- Abstract
Introduction: Dysfunctional voiding (DV) is a habitual voiding disorder caused by involuntary contraction or non-relaxation of the external urethral sphincter (EUS) during voiding. This contraction causes high post-void residuals (PVR), urinary incontinence and urinary tract infections (UTIs). Various treatments for DV are available, but some children do not respond. Intersphincteric botulinum toxin-A (BTX-A) may be a possible treatment for therapy-refractory children with DV., Objective: The aim of this systematic review is to summarize the effects and safety of intersphincteric BTX-A as a treatment for therapy-refractory DV in children., Methods: A systematic search in Embase, MEDLINE, Cochrane, and Web of Science databases was performed. Studies reporting on the usage of intersphincteric BTX-A as a treatment for DV in children were included. Data on PVR, maximum flow rate (Qmax), repeat injections and complications were extracted., Results: From a total of 277 articles, five cohort studies were identified, reporting on 78 children with DV of whom 53 were female (68 %) and 25 were male (32 %). Sample sizes ranged from ten to twenty patients. Mean or median age at the time of intervention ranged from 8 to 10.5 years. Meta-analysis could not be performed due to lack of data. The narrative synthesis approach was therefore used to summarize the results. All studies showed significant decrease in PVR after BTX-A injection. Three studies showed a 33-69 % improvement on incontinence after BTX-A injection. Less UTIs were reported after treatment. A temporary increase in incontinence, UTIs and transitory numbness to the gluteus muscle were reported as side-effects., Conclusions: BTX-A could be a safe and effective treatment option for therapy-refractory DV in children by reducing PVR, UTIs and incontinence. Hereby, the synergistic effect of BTX-A and urotherapy should be emphasized in future management. Furthermore, this study identified gaps in current knowledge that are of interest for future research., Competing Interests: Conflict of interest None., (Copyright © 2023 The Authors.

- Abstract
Background: The first studies on patients with forkhead-box protein P1 (FOXP1) syndrome reported associated global neurodevelopmental delay, autism symptomatology, dysmorphic features and cardiac and urogenital malformations. The aim of this study was to assess the prevalence of congenital abnormalities in an unbiased cohort of patients with FOXP1 syndrome and to document rare complications., Methods: Patients with FOXP1 syndrome were included, mostly diagnosed via whole-exome sequencing for neurodevelopmental delay. A parent-report questionnaire was used to assess medical signs and symptoms, including questions about features rated as most burdensome by patients and their family., Results: Forty individuals were included, 20 females and 20 males. The mean age at assessment was 13.2 years (median 8.5 years; range 2-54 years; ≥18 years n = 7). Seven adults were included. All patients had developmental problems, including cognitive, communication, social-emotional and motor delays. The most prevalent medical signs and symptoms include delayed bladder control, sleeping problems, hypermetropia, strabismus, sacral dimple, undescended testes, abnormal muscle tone and airway infections. The most burdensome complaints for patients with FOXP1 syndrome, as perceived by parents, include intellectual disability, impaired communication, behaviour problems, lack of age-appropriate self-reliance, attention problems and anxiety. According to parents, patients have quite similar reported symptoms, although incontinence, obsessions and a complex sensory profile have a higher ranking., Conclusion: The results of this study may be used to further guide medical management and identify patient priorities for future research targeted on those features of FOXP1 syndrome that most impair quality of life of patients and their families., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objectives: The aims of this study were to 1) determine the success rate of the tined lead test phase in patients with nonobstructive urinary retention (NOUR), 2) determine predictive factors of a successful test phase in patients with NOUR, and 3) determine long-term treatment efficacy and satisfaction in patients with NOUR., Materials and Methods: The first part was a multicenter retrospective study at two centers in The Netherlands. Patients with NOUR received a four-week tined lead test phase. Success was defined as a ≥50% reduction of clean intermittent catheterization frequency or postvoid residual. We analyzed possible predictors of success with multivariable logistic regression. Second, all patients received a questionnaire to assess efficacy, perceived health (Patient Global Impression of Improvement), and treatment satisfaction., Results: This study included 215 consecutive patients (82 men and 133 women) who underwent a tined lead test phase for the treatment of NOUR. The success rate in women was significantly higher than in men, respectively 62% (83/133) and 22% (18/82, p < 0.001). In women, age per ten years (odds ratio [OR] 0.74, 95% CI: 0.59-0.93) and a history of psychiatric illness (OR 3.92, 95% CI: 1.51-10.2), including posttraumatic stress disorder (PTSD), significantly predicted first stage sacral neuromodulation (SNM) success. In men, age per ten years (OR 0.43, 95% CI: 0.25-0.72) and previous transurethral resection of the prostate and/or bladder neck incision (OR 7.71, 95% CI: 1.43-41.5) were significant predictors of success. Conversely, inability to void during a urodynamic study (for women, OR 0.79, 95% CI: 0.35-1.78; for men, OR 3.06, 95% CI: 0.83-11.3) was not predictive of success. Of the patients with a successful first stage, 75% (76/101) responded to the questionnaire at a median follow-up of three years. Of these patients, 87% (66/76) continued to use their SNM system, and 92% (70/76) would recommend SNM to other patients., Conclusions: A history of psychiatric illness, including PTSD, in women with NOUR increased the odds of first stage SNM success 3.92 times. A previous transurethral resection of the prostate and/or bladder neck incision in men increased the odds of success 7.71 times. In addition, a ten-year age increase was associated with an OR of 0.43 in men and 0.74 in women, indicating a 2.3- and 1.3-times decreased odds of success, respectively., (Copyright © 2022 The Authors.

- Abstract
Introduction: Neurogenic lower urinary tract dysfunction (NLUTD) in children can cause renal failure and urinary incontinence if not treated sufficiently. Antimuscarinics (AM) and intradetrusor botulinum toxin injections (BoNT-A) with clean intermittent catheterization (CIC) are widely used treatment options for children with NLUTD. However, a considerable number will become refractory to these treatment options. This study aimed to evaluate the efficacy and long-term outcomes of mirabegron in children with NLUTD as an add-on and as a stand-alone treatment., Material and Methods: Patients under 18 years of age with NLUTD who were refractory to AM and/or BoNT-A and were treated with mirabegron 50 mg were retrospectively studied. Mirabegron was either used as monotherapy or in addition to AM and/or BoNT-A. Video-urodynamic studies (VUDSs) were performed before and after treatment with mirabegron. Changes in video-urodynamic parameters, the need for other NLUTD therapy during follow-up, patient-reported side effects, and urinary incontinence were outcomes of interest., Results: A total of 34 patients with NLUTD were included. All patients were on CIC and the median age was 13.1 years (IQR 15.9-10.3). Median follow-up was 31.4 months (IQR 57.4-11.4). Bladder compliance improved by 89.9%, from 14.9 to 28.3 ml/cm H
2 O (p-value<0.001). Maximum cystometric capacity, end-filling detrusor pressure, volume at first detrusor overactivity, vesicoureteral reflux, and urinary incontinence significantly improved after mirabegron. The add-on therapy group showed more significant improvements in video-urodynamic outcomes compared to the monotherapy group. The median time of requiring other NLUTD therapy was 25.5 months (IQR 39.8-14.8). None of the included patients reported side effects., Conclusions: Mirabegron is an effective treatment for children with therapy-refractory NLUTD with an average efficacy of 2 years after which additional therapy is required. Despite the retrospective character of this study, our results confirm the beneficial effect of mirabegron in children with therapy-refractory NLUTD, in particular when mirabegron is used as add-on therapy in those with low-compliance bladders., Competing Interests: Conflicts of interest All authors declare to have no potential or actual conflict of interest., (Copyright © 2023 The Authors.

- Abstract
Objectives: Our aim was to evaluate trends and regional differences in the use of indwelling and intermittent urinary catheters in the community setting in the Netherlands from 2012 to 2021., Design and Methods: For this population-based cohort study, data on catheter use was collected from the Drug and Medical Devices Information System of the National Healthcare Institute of the Netherlands. This database contains information on the Dutch insured population, which was 100% of the total population in 2018. Users were divided into 12 provinces according to the Nomenclature of Territorial Units for Statistics codes. The number of catheter users was adjusted for the total population of the provinces by sex and age, and was expressed by users per 100,000 people. Negative binomial regression (NBR) was used to test for differences in clean intermittent catheter (CIC) and indwelling catheter (IDC) users across Dutch provinces., Results: Between 2012 and 2021, IDC users increased by 44.6% from 41,619 to 60,172, and CIC users increased by 27.3% from 34,204 to 43,528. The greatest increases were mainly observed among IDC users over 85 years old and male CIC users over 65 years old. NBR showed significant differences for IDC and CIC users between the 12 provinces. CIC incidence was higher in Drenthe and Groningen (Northern Netherlands) compared to Zuid-Holland (Southern Netherlands). IDC incidence was higher in seven provinces dispersed throughout the Netherlands compared to Noord-Holland., Conclusion: CIC and IDC users have continued to increase in recent years; this was especially observed among older men. In addition, there were regional differences in the number of CIC and IDC users; CIC was more prominent in the northern region of the Netherlands, and IDC varied between multiple provinces. Practice variation in urinary catheterization may result from patient population differences or healthcare provider preferences and their alignment with guidelines., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2023.)

- Abstract
Background: The diagnosis of a clinically significant catheter-associated urinary tract infection (CAUTI) in patients performing clean intermittent catheterization (CIC) or with an indwelling catheter (IC) can be challenging., Objective: To get an insight into the variation of the used definition, diagnosis and management of CAUTIs by relevant healthcare workers in the Netherlands., Design: An online clinical scenario-based survey., Methods: The survey was built in Limesurvey and distributed to healthcare workers from randomly selected urology departments, rehabilitation departments/centres and general practice offices between January and May 2022. Questions regarding their field of experience, management strategies, used guidelines and two hypothetical cases with clinical scenarios of a possible CAUTI were included., Results: A total of 172 individuals participated, of which 112 completed the survey. In all, 32 individuals who completed the survey partially were also included. Participants consisted of 68 [44 urologists, 22 rehabilitation doctors (RDs) and 2 general practitioners (GPs)] doctors, 60 nurses (46 from the urology department and 14 from rehabilitation centres/departments) and 16 medical assistants (13 from urology department and 3 from GP offices). The majority consulted patients with an IC or on CIC on a daily/weekly or monthly basis. In all, 35 urologists (79.5%), 9 RDs (40.9%), 21 (45.7%) nurses in the urology department and 6 (42.9%) nurses from a rehabilitation department/centre indicated bladder irrigation as a treatment option for prevention/treatment of CAUTIs, treatment of symptoms or treatment of blockage of the catheter. In the clinical scenarios presented, treatment discrepancies were seen between subspecialties and healthcare workers. Various guidelines were named for the definition of CAUTIs., Conclusion: A considerable variation in diagnoses and management of CAUTIs between the healthcare workers involved was seen. Uniformity in diagnosing and managing CAUTIs, to prevent overtreatment and possible resistance to antibiotics, is advised. Suitable multidisciplinary guidelines are preferred., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2023.)

- Abstract
Purpose: The global prevalence of overactive bladder (OAB) is estimated at 11.8%. Despite existing treatment options such as sacral neuromodulation, a substantial number of patients remain untreated. One potential alternative is noninvasive transcutaneous electrical stimulation. This form of stimulation does not necessitate the implantation of an electrode, thereby eliminating the need for highly skilled surgeons, expensive implantable devices, or regular hospital visits. We hypothesized that alternative neural pathways can impact bladder contraction., Methods: In this pilot study, we conducted transcutaneous electrical stimulation of the abdominal wall (T6-L1), the ear (vagus nerve), and the ankle (tibial nerve) of 3 anesthetized female Sprague-Dawley rats. Stimulation was administered within a range of 20 Hz to 20 kHz, and its impact on intravesical pressure was measured. We focused on 3 primary outcomes related to intravesical pressure: (1) the pressure change from the onset of a contraction to its peak, (2) the average duration of contraction, and (3) the number of contractions within a specified timeframe. These measurements were taken while the bladder was filled with either saline or acetic acid (serving as a model for OAB)., Results: Transcutaneous stimulation of the abdominal wall, ear, and ankle at a frequency of 20 Hz decreased the number of bladder contractions during infusion with acetic acid. As revealed by a comparison of various stimulation frequencies of the tibial nerve during bladder infusion with acetic acid, the duration of contraction was significantly shorter during stimulation at 1 kHz and 3 kHz relative to stimulation at 20 Hz (P = 0.025 and P = 0.044, respectively)., Conclusion: The application of transcutaneous electrical stimulation to the abdominal wall, ear, and tibial nerve could provide less invasive and more cost-effective treatment options for OAB relative to percutaneous tibial nerve stimulation and sacral neuromodulation. A follow-up study involving a larger sample size is recommended.

- Abstract
The first two objectives were to establish which stimulation parameters of kilohertz frequency alternating current (KHFAC) neuromodulation influence the effectiveness of pudendal nerve block and its safety. The third aim was to determine whether KHFAC neuromodulation of the pudendal nerve can relax the pelvic musculature, including the anal sphincter. Simulation experiments were conducted to establish which parameters can be adjusted to improve the effectiveness and safety of the nerve block. The outcome measures were block threshold (measure of effectiveness) and block threshold charge per phase (measure of safety). In vivo, the pudendal nerves in 11 male and 2 female anesthetized Sprague Dawley rats were stimulated in the range of 10 Hz to 40 kHz, and the effect on anal pressure was measured. The simulations showed that block threshold and block threshold charge per phase depend on waveform, interphase delay, electrode-to-axon distance, interpolar distance, and electrode array orientation. In vivo, the average anal pressure during unilateral KHFAC stimulation was significantly lower than the average peak anal pressure during low-frequency stimulation (p < 0.001). Stimulation with 20 kHz and 40 kHz (square wave, 10 V amplitude, 50% duty cycle, no interphase delay) induced the largest anal pressure decrease during both unilateral and bilateral stimulation. However, no statistically significant differences were detected between the different frequencies. This study showed that waveform, interphase delay and the alignment of the electrode along the nerve affect the effectiveness and safety of KHFAC stimulation. Additionally, we showed that KHFAC neuromodulation of the pudendal nerves with an electrode array effectively reduces anal pressure in rats., Competing Interests: The authors report no conflicts of interest in this work.

- Abstract
Background: Urinary incontinence is a prevalent form of pelvic floor dysfunction, with a non-negligible impact on a patient's quality of life. There are several treatment options, varying from conservative to invasive. The aim of this study is to predict treatment outcomes of pure or predominant urge urinary incontinence (UUI) in women to support shared decision-making and manage patient expectations., Methods: Data on patient characteristics, disease history, and investigations of 512 consecutive women treated for UUI in three hospitals in the Netherlands were retrospectively collected. The predicted outcome was the short-term subjective continence outcome, defined as patient-reported continence 3 months after treatment categorized as cure (no urinary leakage), improvement (any degree of improvement of urinary leakage), and failure (no improvement or worsening of urinary leakage). Multivariable ordinal regression with backward stepwise selection was performed to analyze association between outcome and patient's characteristics. Interactions between patient characteristics and treatment were added to estimate individual treatment benefit. Discriminative ability was assessed with the ordinal c-statistic., Results: Conservative treatment was applied in 12% of the patients, pharmacological in 62%, and invasive in 26%. Subjective continence outcome was cure, improvement, and failure in 20%, 49%, and 31%, respectively. Number of incontinence episodes per day, voiding frequency during the day, subjective quantity of UI, coexistence of stress urinary incontinence (SUI), night incontinence, and bladder capacity and the interactions between these variables were included in the model. After internal validation, the ordinal c-statistic was 0.699., Conclusions: Six variables were of value to predict pure or predominant UUI treatment outcome in women. Further development into a comprehensive set of models for the use in various pelvic floor disorders and treatments is recommended to optimize individualized care. This model requires external validation before implementation in clinical practice., Competing Interests: Conflict of interest statement: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2022.)

- Abstract
Introduction: Chronic urinary retention is a common lower urinary tract disorder, mostly neurogenic or idiopathic in origin. The preferred treatment is clean intermittent urinary self-catheterisation (CISC) four to six times a day. In most European countries, virtually all patients use single use catheters, which is in contrast to several countries where the use of reusable catheters is more common. The available literature on the use of reusable catheters is conflicting and until now, no randomised controlled trial with sufficient power has been performed to investigate if reusable catheters for CISC is as safe as single use catheters., Methods and Analysis: We described this protocol for a prospective, randomised controlled non-inferiority trial to investigate if the use of reusable catheters is as safe as single use catheters for CISC patients, measured by symptomatic urinary tract infections (sUTIs). Secondary objectives are adverse events due to a sUTI, urethral damage, stone formation, quality of life and patient satisfaction. A cost-effectiveness analysis will also be performed. 456 Participants will be randomised into two groups stratified for age, gender, menopausal status and (non-)neurogenic underlying disorder. The intervention group will replace the reusable catheter set every 2 weeks for a new set and replace the cleaning solution every 24 hours. The control group continues to use its own catheters. The primary outcome (amount of sUTIs from baseline to 1 year) will be tested for non-inferiority. Categorical outcome measures will be analysed using χ
2 tests and quantitative outcome variables by t-tests or Mann-Whitney U tests. Two-sided p values will be calculated., Ethics and Dissemination: This protocol was reviewed and approved by the Medical Ethics Committee of the Erasmus MC (MEC 2019-0134) and will be performed according to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for non-inferiority trials. The results of this randomised controlled non-inferiority trial will be published in a peer-reviewed journal and will be publicly available., Trial Registration Number: NL8296., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

- Abstract
Background: Neurogenic bowel dysfunction (NBD), like fecal incontinence and constipation, is a common symptom of disease in patients with multiple sclerosis (MS). The NBD score is a validated symptom-based questionnaire consisting of 10 multiple-choice questions. The aim of this study was to validate the Dutch version of the NBD score in patients with MS, creating an objective measuring tool of bowel dysfunction., Methods: Translation and validation of the NBD score was performed according to standardized guidelines. Adult patients with MS visiting a urology department completed a set of questionnaires (test): the NBD score, the Fecal Incontinence Quality of Life scale (FIQL), the Fecal Incontinence Severity Index (FISI), and the EQ-5D 3-Level questionnaire (EQ-5D-3L). After 1 to 2 weeks, the questionnaires were completed again (retest). A control group recruited at a general practitioner's practice completed the questionnaires once. Data were analyzed for measurement properties., Results: Sixty-one patients and 50 controls were included. Content validity was adequate, internal consistency was moderate (Cronbach α = 0.57 and 0.41), and reproducibility was excellent (interclass correlation coefficient = 0.78). Criterion validity was confirmed; the NBD score correlated moderately/strongly with the FIQL, FISI, and EQ-5D-3L. The NBD scores in the patient group were significantly higher than those in the control group, demonstrating good construct validity., Conclusions: The Dutch version of the NBD score showed moderate to good validity and good reliability for assessment of NBD in patients with MS., Competing Interests: Financial Disclosures: The authors declare no conflicts of interest., (© 2022 Consortium of Multiple Sclerosis Centers.)

- Abstract
Study Design: This is a prospective validation study., Objectives: The neurogenic bowel dysfunction (NBD) score is a widely used symptom-based questionnaire evaluating bowel dysfunction and its impact on quality of life (QoL) in spinal cord-injured patients. This study aimed to translate and validate a Dutch-language NBD score in patients with SCI., Setting: Patients with SCI visiting the urology department or general practitioner (GP) in Rotterdam, the Netherlands., Methods: Standardized guidelines were followed for the translation and validation process of the NBD score. Adult patients with SCI visiting our urology department were asked to participate by filling in a set of questionnaires: the NBD score, the Fecal Incontinence Quality of Life scale (FIQL), the Fecal Incontinence Severity Index (FISI), and the European Quality of life 5-Dimension 3-Level questionnaire (EQ-5D-3L) at baseline and 1-2 weeks afterward. A control group recruited at a GP office completed the questionnaires once. The following measurement properties were evaluated: content validity, internal consistency, reproducibility, criterion-, and construct validity., Results: Fifty-eight patients and 50 references were included. Content validity was adequate, internal consistency was moderate (Cronbach's alpha 0.56 and 0.30) and reproducibility was adequate (ICC 0.87). Criterion validity was confirmed; NBD score correlated significantly with the FIQL, FISI, and EQ-5D-3L. NBD scores in the patient group were significantly higher than in references, demonstrating good construct validity., Conclusions: The Dutch-language version of the NBD score showed moderate to good measurement properties, and therefore is a reliable tool to measure bowel dysfunction in patients with SCI. We recommend standardized usage of this questionnaire for clinical evaluation and research purposes., (© 2021. The Author(s), under exclusive licence to International Spinal Cord Society.)

- Abstract
Context: Transcutaneous electrical nerve stimulation (TENS) and percutaneous tibial nerve stimulation (PTNS) provide minimally invasive ways to treat idiopathic nonobstructive urinary retention (NOUR)., Objective: To assess the efficacy of TENS and PTNS for treating idiopathic NOUR., Evidence Acquisition: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Embase, Medline, Web of Science Core Collection, and the Cochrane CENTRAL register of trials were searched for all relevant publications until April 2020., Evidence Synthesis: A total of 3307 records were screened based on the title and abstract. Eight studies met the inclusion criteria and none of the exclusion criteria. Five studies, all from the same group, reported the efficacy of PTNS and two that of TENS in adults with idiopathic NOUR. One study reported the efficacy of TENS in children with idiopathic NOUR. Objective success was defined as a ≥50% decrease in the number of catheterizations per 24 h or in the total catheterized volume in 24 h. The objective success rate of PTNS ranged from 25% to 41%. Subjective success was defined as the patient's request for continued chronic treatment with PTNS, and ranged from 46.7% to 59%. Eighty percent of women who underwent transvaginal stimulation reported an improvement such as a stronger stream when voiding. TENS in children reduced postvoid residual and urinary tract infections., Conclusions: The efficacy of TENS and PTNS in the treatment of idiopathic NOUR is limited and should be verified in larger randomized studies before application in clinical practice., Patient Summary: The outcomes of transcutaneous electrical nerve stimulation and percutaneous tibial nerve stimulation for the treatment of urinary retention of unknown origin were reviewed. Whether these treatments are superior to other treatments could not be established., (Copyright © 2020 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

- Abstract
Purpose: Functional neuroimaging is a powerful and versatile tool to investigate central lower urinary tract (LUT) control. Despite the increasing body of literature there is a lack of comprehensive overviews on LUT control. Thus, we aimed to execute a coordinate based meta-analysis of all PET and fMRI evidence on descending central LUT control, i.e. pelvic floor muscle contraction (PFMC) and micturition., Materials and Methods: A systematic literature search of all relevant libraries was performed in August 2020. Coordinates of activity were extracted from eligible studies to perform an activation likelihood estimation (ALE) using a threshold of uncorrected p <0.001., Results: 20 of 6858 identified studies, published between 1997 and 2020, were included. Twelve studies investigated PFMC (1xPET, 11xfMRI) and eight micturition (3xPET, 5xfMRI). The PFMC ALE analysis (n = 181, 133 foci) showed clusters in the primary motor cortex, supplementary motor cortex, cingulate gyrus, frontal gyrus, thalamus, supramarginal gyrus, and cerebellum. The micturition ALE analysis (n = 107, 98 foci) showed active clusters in the dorsal pons, including the pontine micturition center, the periaqueductal gray, cingulate gyrus, frontal gyrus, insula and ventral pons. Overlap of PFMC and micturition was found in the cingulate gyrus and thalamus., Conclusions: For the first time the involved core brain areas of LUT motor control were determined using ALE. Furthermore, the involved brain areas for PFMC and micturition are partially distinct. Further neuroimaging studies are required to extend this ALE analysis and determine the differences between a healthy and a dysfunctional LUT. This requires standardization of protocols and task-execution., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Aim: The aim of this study is to evaluate the acute effects of sacral neuromodulation (SNM) on various urodynamic parameters., Methods: Patients with overactive bladder and detrusor overactivity (DO) who were planned for percutaneous nerve evaluation (PNE) were included. Directly after the PNE, a urodynamic study (UDS) was performed. The stimulation was turned off during the first UDS (UDS 1), and during the second filling cycle, stimulation was turned on (UDS 2). The UDS was followed by a test phase of 1 week and the bladder diaries were evaluated during an outpatient clinic visit. Primary outcome measures were the differences in UDS parameter values with SNM off and on., Results: Ten female patients were included in the study and completed the study protocol. Eight patients showed ≥50% improvement of symptoms following a test phase. There were no differences between UDS 1 and UDS 2 in the UDS parameters; bladder volume at first sensation, bladder volume at first DO, highest DO pressure, bladder capacity, maximum flow rate, and pressure at maximum flow rate., Discussion: None of the aforementioned urodynamic parameters was influenced by acute SNM in patients who responded to SNM. To the best of our knowledge, this is the first study investigating the acute effects of SNM on bladder function., (© 2019 The Authors.

- Abstract
Aim: The primary aim of this study is to demonstrate that 7-tesla functional magnetic resonance imaging (7T-fMRI) can visualize the neural representations of the male pelvic floor in the whole brain of a single subject., Methods: In total, 17 healthy male volunteers (age 20-47) were scanned in a 7T-MRI scanner (Philips Achieva). The scanning protocol consisted of two functional runs using a multiband echo planar imaging sequence and a T1-weighted scan. The subjects executed two motor tasks, one involving consecutive pelvic floor muscle contractions (PFMC) and a control task with tongue movements., Results: In single subjects, results of both tasks were visualized in the cortex, putamen, thalamus, and the cerebellum. Activation was seen during PFMC in the superomedial and inferolateral primary motor cortex (M1), supplementary motor area (SMA), insula, midcingulate gyrus (MCG), putamen, thalamus, and in the anterior and posterior lobes of the cerebellum. During tongue movement, activation was seen in the inferolateral M1, SMA, MCG, putamen, thalamus, and anterior and posterior lobes of the cerebellum. Tongue activation was found in the proximity of, but not overlapping with, the PFMC activation. Connectivity analysis demonstrated differences in neural networks involved in PFMC and tongue movement., Conclusion: This study demonstrated that 7T-fMRI can be used to visualize brain areas involved in pelvic floor control in the whole brain of single subjects and defined the specific brain areas involved in PFMC. Distinct differences between brain mechanisms controlling the pelvic floor and tongue movements were demonstrated using connectivity analysis., (© 2019 The Authors.

- Abstract
Objective: Myelomeningocele (MMC) is the most common form of spina bifida, with a lifelong impact on the quality of life for infants born with this condition. In recent decades, fetal surgery has evolved from an experimental therapy to standard of care for many centers in the world. In this study, the authors aimed to provide an overview of the current management and outcomes for infants with MMC managed at their institution. This then provides a center-specific historical cohort for comparison with future antenatal-treated MMC cases., Methods: This is a retrospective, single-institution cohort study including all consecutive MMC cases between January 1, 2000, and June 1, 2018, at Erasmus MC. Outcome data included closure of the defect (location, timing, and surgical parameters), hydrocephalus management, Chiari malformation type II (CMTII) management, incidence of spinal cord tethering and outcome, motor outcomes, and continence., Results: A total of 93 patients were included with predominantly lumbosacral lesions. Two patients died during follow-up. Hydrocephalus was present in 84%, with a 71% ventriculoperitoneal shunt reoperation rate. Surgery was performed in 12% for a tethered spinal cord at a mean age of 8 years. Decompression surgery was performed in 3 patients for CMTII. Special education in 63% was significantly associated with hydrocephalus (p < 0.015). Nineteen percent of patients were able to walk independently, and 47% were nonambulators. Social continence for urine was obtained in 75% of patients, 4% had fecal incontinence., Conclusions: This study provides an overview of current MMC outcomes at the authors' center and will serve as a historical cohort for comparison with future fetal surgery cases operated on at the center in the coming years. Apart from a relatively low surgical untethering rate, the authors' outcome data are comparable to those in the literature. Hydrocephalus is highly prevalent in postnatally treated MMC patients; in this study as in much of the literature, hydrocephalus is correlated with a low cognitive function. Fetal surgery for MMC halves the need for shunt treatment in a select group of MMC pregnancies, constituting a major indication for us to undergo the transition to a fetal surgery center. The fetal benefits of open antenatal surgery for MMC are well established, yet long-term data on especially tethered spinal cord are eagerly awaited.

- Abstract
Context: Surgical treatment of anatomic bladder outlet obstruction (BOO) may be indicated in males with neurogenic bladder dysfunction. A bothersome complication after surgery is urinary incontinence., Objective: To identify the optimal practice in the surgical treatment of anatomic BOO in males with neurogenic bladder dysfunction, due to multiple sclerosis, Parkinson disease, spinal cord injury (SCI), spina bifida, or cerebrovascular accident (CVA)., Evidence Acquisition: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Medline, Embase, Cochrane controlled trial databases, Web of Science, and Google Scholar were searched for publications until January 2017., Evidence Synthesis: A total of 930 abstracts were screened. Eight studies were included. The types of anatomic BOO discussed were benign prostate obstruction, urethral stricture, and bladder neck sclerosis. The identified surgical treatments were transurethral resection of the prostate (TURP) in patients with Parkinson, CVA or SCI, endoscopic treatment of urethral stricture by laser ablation or urethrotomy (mainly in SCI patients), and bladder neck resection (BNR) in SCI patients. The outcome of TURP may be highly variable, and includes persistent or de novo urinary incontinence, regained normal micturition control, and urinary continence. Good results were seen in BNR and endoscopic urethrotomy studies. Laser ablation and cold knife urethrotomy resulted in restarting intermittent catheterization or adequate voiding. Overall, a high risk of bias was found., Conclusions: This systematic review provides an overview of the current literature on the outcome of several surgical approaches of different types of anatomic BOO in males with neurogenic bladder dysfunction. Identifying the optimal practice was impossible due to limited availability of high-quality studies., Patient Summary: The outcome of several surgical approaches in males with neurogenic bladder dysfunction with benign prostate obstruction, urethral stricture, or bladder neck sclerosis is overviewed. The optimal practice could not be identified., (Copyright © 2018 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

- Abstract
Aims: The overactive bladder quality of life short-form questionnaire (OAB-q SF) evaluates both symptom bother and health-related quality of life in patients with OAB, a highly prevalent disease. The objective of this study was to translate and validate a Dutch version of the OAB-q SF., Methods: The translation into Dutch and validation process of the OAB-q SF was performed according to standardized guidelines. Patients with OAB who visited the department of Urology outpatient clinic completed the questionnaires OAB-q SF, European Quality of life 5-Dimension 5-Level questionnaire (EQ-5D-5L), Urogenital Distress Inventory 6 (UDI-6), and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) at baseline (test) and 2 weeks later (retest). A reference group from the department of Allergology outpatient clinic completed the same questionnaires once. The evaluated measurement properties included content validity, internal consistency, reproducibility, criterion validity, and construct validity., Results: Fifty-two patients were included in the study group and 51 references were included. The content validity was adequate and the internal consistency was excellent (Cronbach's α > 0.80). The reproducibility was good with intraclass correlation coefficients higher than 0.70. Patient's OAB-q SF scores were moderately to strongly correlated with the UDI-6, ICIQ-OAB, and the EQ-5D-5L confirming the criterion validity. A good construct validity was demonstrated with significant higher scores of the OAB-q SF score in patients compared to references., Conclusions: The Dutch OAB-q SF is a reliable and valid measure to evaluate symptom bother and health-related quality of life in patients with OAB., (© 2019 The Authors.

- Abstract
Objectives: To evaluate the long-term results after the construction of a Continent Catheterizable Urinary Conduit (CCUC) in adults. Methods: This study retrospectively reviewed the charts of 41 adults from two tertiary centers who received a CCUC. The demographics, underlying diseases, indications for a CCUC and outcomes such as the reoperation rate and the occurrence of complications were extracted. The patient reported outcome was measured with the Patient Global Impression of Improvement (PGI-I) scale and four additional questions about continence, leakage and stomal problems. Results: Twenty-nine patients were women. The median age at surgery was 32 years, with a median follow-up of 52 months. Twenty-six patients had a neurogenic bladder. The reoperation rate was 48.8%, with a median of 10.5 months after constructing the CCUC. Superficial stomal stenosis was the most common registered complication (20 times) and stoma revision was the most often performed reoperation (12 times). Twenty-four patients completed the PGI-I; the mean improvement rating was 2 (=much better). Conclusion: The construction of a CCUC in adults is associated with a high complication and reoperation rate. The high reoperation rate is in accordance with the sparse literature. Despite this, patients reported 'much better' on the PGI-I.

- Abstract
Aim: To evaluate the outcome of adjustable continence balloons in the treatment of stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP)., Methods: In two tertiary centers, adjustable continence balloons were implanted in 29 patients with post-TURP SUI between 2007 and 2018. Endpoints of this retrospective multicenter study were patient-reported changes in pad count and complications. Dry was defined as no pad or one security pad., Results: Preoperative urinary incontinence was mild in 7 (24%), moderate in 12 (41%), and severe in 10 (35%) patients. The median follow-up duration was 21 (interquartile range [IQR], 11-43) months. Within 30 days postoperatively, a Clavien-Dindo grade less than or equal to II complication occurred in 24% of the patients. Reintervention rate was 24%. Six and 12 months after implantation, the International Prostate Symptom Score (IPSS) quality-of-life item improved significantly from 5 (IQR, 5-6) preoperatively to 3 (IQR, 1-4.5) and 1 (IQR, 0-3), respectively. At last visit (median 21 months after implantation), the outcome on continence had improved in 76% of the patients, including, 45% dry patients. After a median follow-up of 28 months (IQR, 13-63; N = 23), all but one patient reported improvement on the Patient Global Impression of Improvement (PGI-I) scale. In detail, 10 patients reported "very much better" condition compared with before the implantation, 10 patients "much better," two patients "a little better," and one patient "no change." Daily pad use decreased from three (IQR, 2-5) to one (IQR, 0-2) pads/day (P < 0.001)., Conclusions: This is hitherto, the first study reporting results of adjustable continence balloons in the treatment of post-TURP SUI. The therapy was found to be safe and efficient. The majority of our study population reported improvement on their condition and greater than or equal to 50% reduction in daily pad use., (© 2019 The Authors.

- Abstract
Introduction: Achieving continence in children with neurogenic sphincteric incompetence is a challenge. Awareness of the long-term outcome in this young patient population is important. In the past 25 years, the study institution has built experience in bladder outlet procedures such as bladder neck sling and bladder neck reconstructions., Objective: The objective of this study was to evaluate the long-term outcome on continence and re-intervention rate of bladder outlet procedures in children with neurogenic urinary incontinence at the study institution., Design: All children who underwent a bladder neck procedure between 1992 and 2017 at the study institution were retrospectively reviewed. Continence at the end of follow-up was the primary endpoint, defined as 'dry' when there was an interval of a minimum of 4 h without urinary leakage. Non-parametric tests were used for statistical analysis., Results: During this 25-year period, a total of 60 children underwent a bladder outlet procedure, either a bladder neck sling (n = 43) or a bladder neck reconstruction (n = 17). The median age at surgery was 11.6 years (interquartile range [IQR] 7.8-13.9). Concomitant surgery consisted of bladder augmentation in 80% and continent catheterizable urinary channel in 97% of children. Dry rate within 1 year was 38%. After a median follow-up of 10.4 years (IQR 6.5-15.5), 77% of all children were dry. Twenty-five children (42%) needed one or more re-interventions, including redo of the bladder outlet procedure, other type of outlet procedure, bulking agents, bladder augmentation, and bladder neck closure., Discussion: This study confirms that achieving continence is a challenge. The inconsistent use of the definition of urinary continence creates confusion in the literature and makes comparison of outcome with other studies difficult. Openness of (long-term) results in achieving urinary continence is important and helpful for future patients., Conclusion: On the long term, the majority of children with neurogenic urinary incontinence were dry after a bladder outlet procedure, but a considerable number of patients had a re-intervention. The initial outcome on continence was slightly disappointing. Reporting long-term results is essential and helpful for patient counseling., (Copyright © 2018 Journal of Pediatric Urology Company.

- Abstract
Aims: The Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15) evaluates symptoms of sexual dysfunction in patients with multiple sclerosis (MS). The objective of this study was to provide and validate a Dutch version of the MSISQ-15 in patients with neurological disease such as MS and spinal cord injury (SCI)., Methods: The linguistic validation process of the original English MSISQ-15 into Dutch was performed according to standardized guidelines. Sexually active patients with MS or spinal cord disorders, including SCI and cauda equine syndrome, who visited a tertiary urology center or a rehabilitation center completed the MSISQ-15, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women, or International Index of Erection Function (IIEF-15) in men at baseline (test) and 2 weeks later (retest). A reference group recruited from a general medical practice completed the questionnaires once. Data were analyzed for measurement properties., Results: Fifty-three patients with MS, 49 patients with spinal cord disorder, and 50 references were included. Content validity was adequate. Internal consistency (Cronbach's alpha >0.8) and reproducibility (intraclass correlation coefficient >0.8) of the MSISQ-15 were excellent. Patients' MSISQ-15 scores were correlated with severity of symptoms of sexual dysfunction measured by PISQ-12 or IIEF-15 and confirmed positive rating for criterion validity. MSISQ-15 scores in patients were higher than in references (on a scale of 15-75: 38.9 ± 11.4 vs 21.1 ± 5.4; P < 0.001), indicating good construct validity., Conclusions: The Dutch MSISQ-15 is a reliable and valid measure to evaluate symptoms of sexual dysfunction in patients with MS or with SCI., (© 2018 The Authors.

- Abstract
Aims: We sought to establish the responsiveness of the Dutch Vancouver Symptom Score for Dysfunctional Elimination Syndrome (VSSDES) and Pediatric urinary incontinence Quality of life (PinQ) questionnaires. Secondary, we evaluated the outcome of urotherapy extended for children with dysfunctional voiding (DV)., Methods: This cross-sectional multicenter study was done in one tertiary and two community hospitals. Children with DV were included, also when refractory to previous urotherapeutic treatment. The questionnaires were completed before and after urotherapy. The primary outcome measure was the responsiveness of the Dutch VSDESS and PinQ. Secondary outcome was the initial success (defined by the International Children's Continence Society) of extended urotherapy., Results: Between June 2014 and May 2016, 64 children (median age 7 years, IQR 6-10) received urotherapy (median 18 weeks, IQR 11-28). In contrast to the VSSDES, the PinQ showed good responsiveness. For children and parents, respectively, the area under the ROC-curve was 0.79 (P = 0.01) and 0.72 (P = 0.03) for the PinQ and 0.50 (P = 0.98) and 0.55 (P = 0.62) for the VSSDES. Fifty children received extended urotherapy, 27 had complete, and 14 had partial response. Sixteen children had been refractory to previous treatment; four showed complete, and six showed partial response., Conclusion: The PinQ is able to detect clinically important changes in continence-specific quality of life after treatment. We support the use of the VSSDES questionnaire in addition to the current diagnostics for the diagnosis of DV. Extended urotherapy showed to be a successful treatment for children with DV, also for those who had received previous unsuccessful treatment., (© 2018 The Authors.

Aims: To evaluate our outcomes of the adjustable continence balloons ProACT™ for the treatment of male stress urinary incontinence after radical prostatectomy., Methods: Between May 2007-August 2016 the ProACT™ was implanted in 143 patients without a history of radiotherapy. Endpoints were patient-reported changes in pad counts and complications. Treatment was considered successful if no pad or just one "security" pad per day sufficed, and improved if daily pad use was reduced by ≥50%., Results: Incontinence before implantation was mild in 36 (25%), moderate in 57 (40%), and severe in 50 (35%) patients. Complications within 30 days were classified by the Clavien-Dindo classification; eight (5.6%) grade I, three (2.1%) grade II, three (2.1%) grade IIIb, and 129 (90.2%) patients had no complication. Revision was done in 43 (30%) patients. The IPSS quality of life item improved significantly from 5.0 (IQR 4.0-5.0) preoperative to 2.0 (IQR 1.0-4.0) and 1.0 (IQR 0.0-3.0) 6 and 12 months after implantation, respectively. After a median follow up of 56 months (range 28 to 79, n = 112), 72 (64%) patients were improved, including 51 (45%) patients were successful. Daily pad use decreased from 3.0 to 1.0 (67% reduction). The median outcome on the Patient Global Impression of Improvement scale was "much better," and 97 (87%) patients perceived improvement., Conclusions: The minimally invasive ProACT™ device showed a clear beneficial continence outcome in patients with stress urinary incontinence after radical prostatectomy. The majority of the patients were satisfied and perceived improvement ≥50% on daily pad use on the long term., (© 2017 The Authors. Neurourology and Urodynamics Published by Wiley Periodicals, Inc.)

- Abstract
Aims: To describe all outcome parameters and definitions of cure used to report on outcome of surgical interventions for stress urinary incontinence (SUI) in neuro-urological (NU) patients., Methods: This systematic review was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The study protocol was registered and published (CRD42016033303; http://www.crd.york.ac.uk/PROSPERO). Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov were systematically searched for relevant publications until February 2017., Results: A total of 3168 abstracts were screened. Seventeen studies reporting on SUI surgeries in NU patients were included. Sixteen different outcome parameters and nine definitions of cure were used. Six studies reported on objective outcome parameters mainly derived from urodynamic investigations. All studies reported on one or more subjective outcome parameters. Patient-reported pad use (reported during interview) was the most commonly used outcome parameter. Only three of 17 studies used standardized questionnaires (two on impact of incontinence and one on quality of life). Overall, a high risk of bias was found., Conclusions: We found a considerable heterogeneity in outcome parameters and definitions of cure used to report on outcome of surgical interventions for SUI in NU patients. The results of this systematic review may begin the dialogue to a future consensus on this topic. Standardization of outcome parameters and definitions of cure would enable researchers and clinicians to consistently compare outcomes of different studies and therapies., (© 2017 The Authors.

- Abstract
Context: Impaired sexual function has a significant effect on quality of life. Various patient-reported outcome measures (PROMs) are available to evaluate sexual function. The quality of the PROMs to be used for neurologic patients remains unknown., Objective: To systematically review which validated PROMs are available to evaluate sexual function in neurologic patients and to critically assess the quality of the validation studies and measurement properties for each identified PROM., Evidence Acquisition: A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. The included publications were assessed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments checklist., Evidence Synthesis: Twenty-one studies for PROMs regarding sexual function were identified for the following patient groups: spinal cord injury (11 studies), multiple sclerosis (MS; 6 studies), Parkinson's disease (2 studies), traumatic brain injury (1 study), and epilepsy (1 study). The evidence for the quality of PROMs was found to be variable, and overall evaluation of measurement properties was lacking in 71% of the studies. The measurement error and responsiveness were not studied in any of the publications., Conclusions: Several PROMs have been identified to evaluate sexual function in neurologic patients. Strong evidence was found only for the Multiple Sclerosis Intimacy and Sexuality Questionnaire-15 and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 for patients with MS, although evidence was lacking for certain measurement properties as well. Future research should focus on identifying relevant PROMs and establishing adequate quality for all measurement properties in studies with high methodological quality., Patient Summary: A quality assessment of patient-reported outcome measures (PROMs) for sexual function in neurologic patients was made. The evidence found for good PROMs was limited. Studies with high methodological quality are needed to improve the quality of PROMs to evaluate sexual function in neurologic patients., (Copyright © 2016 European Association of Urology.

- Abstract
Background: Optimizing the patients' quality of life is one of the main goals in the urological management of spinal cord injury (SCI) patients. In this study we validated the Dutch SF-Qualiveen, a short questionnaire that measures the urinary-specific quality of life, in SCI patients. No such measure is yet available for this patient group., Methods: In 2015-2016 SCI patients with urinary symptomatology who visited the outpatient clinics of Urology at the Erasmus Medical Centre and Rehabilitation at Rijndam Revalidation completed the SF-Qualiveen and UDI-6 during the visit and 1-2 weeks later. The UDI-6, a urinary tract symptom inventory, served as gold standard. Controls, recruited from the Otolaryngology outpatient clinic, completed the questionnaires once. Content-, construct-, and criterion validity and reliability (internal consistency and reproducibility) of the SF-Qualiveen were determined., Results: Fifty seven SCI patients and 50 controls were included. 12 SCI patients asserted that the SF-Qualiveen covered their bladder problems (good content validity). Patients' SF-Qualiveen scores being positively associated with severity of urinary symptoms and patients' scores being higher than those of controls indicated good construct validity. The positive association that was found between SF-Qualiveen and UDI-6 in patients (r = 0.66-0.67, P < 0.001) and controls (r = 0.63, P < 0.001) confirmed good criterion validity. Internal consistency (Cronbach's alpha 0.89-0.92) and reproducibility (intraclass correlation coefficient 0.94) of the SF-Qualiveen were good., Conclusions: The Dutch SF-Qualiveen is a valid and reliable tool to measure the urinary-specific quality of life in SCI patients.

- Abstract
Aims: The SF-Qualiveen is a short questionnaire that measures the impact of urinary symptoms on the quality of life of patients with urological dysfunction due to neurological disorders. The aim of this study is to translate, culturally adapt and validate a Dutch version of the SF-Qualiveen for use in Multiple Sclerosis (MS) patients., Methods: Cross-cultural adaptation of the original English SF-Qualiveen into Dutch was performed according to standardized guidelines. Adult MS patients with symptomatic urinary disorders who visited the Urology or Rehabilitation outpatient clinic of the Erasmus Medical Center completed the SF-Qualiveen and the Urinary Distress Inventory-6 (UDI-6), that evaluates bother caused by lower urinary tract symptoms and was used as a gold standard, at baseline and 1-2 weeks later. A control group recruited from the Otolaryngology outpatient clinic completed the questionnaires once. Reliability and validity were determined., Results: Fifty MS patients and 50 controls were included. SF-Qualiveen scores in patients were higher than in controls (on a scale of 0-4: 1.73 vs. 0.34; P < 0.001). Internal consistency (Cronbach's alpha >0.8) and reproducibility (Intraclass correlation coefficients >0.8) were good for the total SF-Qualiveen. Content validity was adequate and a significant relationship between SF-Qualiveen and UDI-6 (r = 0.510-0.479, P < 0.001) confirmed good criterion validity., Conclusions: The Dutch SF-Qualiveen showed good measurement properties. We recommend its use to measure urinary-specific quality of life in MS patients in research and clinical practice in the Netherlands., (© 2016 Wiley Periodicals, Inc.)

- Abstract
Aims: To evaluate the long-term outcome of appendicovesicostomies and to present the frequency and timing of complications needing re-intervention., Methods: In this retrospective study we included patients in whom an appendicovesicostomy was created at our institution between 1993 and 2011. Patients with a follow-up less than 1 year were excluded. Patient characteristics and conduit-related complications requiring re-intervention were collected., Results: One hundred and twenty-eight patients were included with mean age at initial surgery of 10.1 ± 3.9 years. Two thirds of the children had underlying neurogenic disease. The mean follow-up was 10.1 ± 4.8 years. All but one patient continued to use the catheterizable channel. Re-intervention for conduit-related complications was necessary in 32.0% of the patients. A second, third, and fourth re-intervention was required in respectively 10.9%, 2.3%, and 1.6%. The commonest complications were cutaneous/fascial stenosis in 14.8%, stenosis at conduit-bladder level in 9.4%, and stomal incontinence in 6.3% of the patients. The most performed re-interventions were stoma revision (in 16.4% of the patients), conduit revision (10.2%), and dilatation of a stenotic tract (4.7%). 63.3% of the re-interventions was superficial and/or endoscopic. The peak incidence of re-interventions was in the 1st year after conduit construction and decreased yearly., Conclusions: Our study gives an overview of patients and their conduits developing from prepubertal children to young adults. During a mean follow-up of 10.1 years, roughly one third of the patients needed a re-intervention. We conclude that an appendicovesicostomy is an effective and durable treatment for whom transurethral clean intermittent catheterization is not feasible. Neurourol.

- Abstract
Background: Several studies have shown that the antimuscarinic treatment of overactive bladder is characterized by low long-term persistence rates. We have investigated the persistence of solifenacin in real life by means of telephonic interviews in a prospective cohort. We included both patients with idiopathic overactive bladder as well as neurogenic overactive bladder., Methods: From June 2009 until July 2012 patients with idiopathic or neurogenic overactive bladder who were newly prescribed solifenacin were included. In total 123 subjects were followed prospectively during one year by means of four telephonic interviews, which included questions about medication use and adverse events., Results: After one year 40% of all patients included was still using solifenacin, 50% discontinued and 10% was lost to follow-up. In the neurogenic group 58% was still using solifenacin versus 32% in the idiopathic group after one year (p < 0,05). The main reasons to stop solifenacin were lack of efficacy, side effects and a combination of both., Conclusions: This prospective cohort study showed a real life continuation rate of 40% after 12 months. This continuation rate is higher than found in most other studies. The use of regular telephonic evaluation might have improved medication persistence. The findings of this study also suggest that patients with neurogenic overactive bladder have a better persistence with this method of evaluation compared to patients with idiopathic overactive bladder., Trial Registration: This study was retrospectively registered on march 17, 2017 at the ISRCTN registry with study ID ISRCTN13129226 .

- Abstract
Aims: SNM has been proven to be effective in the treatment of refractory UUI. Total costs and patient burden due to regular battery changes may prevent broad implementation of this treatment. The aim was to achieve a minimal improvement of 50% in incontinence episodes compared to pre-SNM by using iSNM., Methods: This prospective cohort study was performed in women with UUI receiving treatment with SNM for a minimum of 6 months. The neurostimulator was programmed to 8 hr "on" and 16 hr "off" per day for 12 weeks. Prior to iSNM, data were collected during no SNM and cSNM. Bladder diaries and various patient reported outcome measures were collected at predetermined time points: 1-5 weeks, and 8, 12, and 16 weeks. Nonparametric tests were used for the statistical analysis., Results: Of the 19 patients 63% showed an improvement of >50% of incontinence episodes during iSNM compared to pre-SNM. Bladder diary parameters showed a difference between pre-SNM and iSNM median (P-value); incontinence episodes/24 hr, 4.1-1.0 (P = 0.04), incontinence severity, 2.0-1.0 (P = 0.001), voiding episodes/24 hr, 13.0-8.0 (P = 0.001), and voided volume, 149-219 ml (P = 0.04). The UDI-6, 50.0-27.8 (P = 0.03), and the IIQ-7 scores, 50.0-9.5 (P = 0.04) also showed a significant improvement. No difference was demonstrated between iSNM and cSNM., Conclusions: Compared to pre-SNM parameters, iSNM shows an improvement in both objective and subjective outcomes. Specifically no difference was found between iSNM and cSNM, indicating that iSNM could be a feasible and cost-effective alternative. Neurourol.

- Abstract
Purpose of Review: The purpose of this article is to provide an overview about the applicability of botulinum toxin type A (BTX-A) in paediatric neurogenic bladder based on the recently published literature combined with hypothetical notes and future perspectives., Recent Findings: The indications, clinical outcomes, urodynamic outcome parameters and cost-effectiveness are presented from recent publications. Also, alternative routes of application of BTX-A in the bladder are discussed as well as the influence of BTX-A on conservative and invasive treatment., Summary: Intradetrusor BTX-A injections for neurogenic bladder dysfunction are effective in resolving both urinary incontinence and improving urodynamic parameters in most children with a sustained response at repeated injections. In low-compliance bladders, however, if no response is seen after initial BTX-A injection, repeated injections seem to be unnecessary. Because general anaesthesia is mandatory for BTX-A injections in children, alternative routes of application have been investigated such as intravesical installation, electromotive drug application and liposomal drug delivery; however, no definite results have been found in a paediatric clinical setting.

- Abstract
Aims: The objective of this study was to determine the prevalence of female sexual dysfunction (FSD) in patients with Multiple Sclerosis (MS) in one of the leading MS centers in the Netherlands. Furthermore, we evaluated the practice patterns of members of the Dutch Urological Association (DUA) with respect to FSD., Methods: A self-administered Web-based questionnaire for physicians was mailed to all 467 members of the DUA. The questions covered different topics in female sexuality. For the patient survey the Female Sexual Function Index (FSFI) was used., Results: The response rate of the physicians survey was 42% (n = 194). Sixty-one percent of the responders reported to ask their female patients about their sexual function. Thirty-nine percent of the physicians did not ask their patients about sexuality. The majority indicated that they lacked knowledge on FSD or found discussing sexuality not relevant for their practice. The response rate of the patient survey was 28% (n = 85). According to the FSFI questionnaire 32% of the sexually active MS patients experienced FSD. Women with FSD scored low on all subdomains of the FSFI questionnaire. In particular, desire, arousal, lubrication, and the ability to achieve orgasm were affected., Conclusions: The prevalence of FSD in MS patients in our center is about 32%. Overall, many members of the DUA do not screen for sexual dysfunction in female patients because of lack of knowledge on FSD. Better and more structured education of urologists and residents in urology on FSD in The Netherlands is urgently needed. Neurourol.

- Abstract
Neurogenic lower urinary tract dysfunction (LUTD) in multiple sclerosis (MS) is highly prevalent in adults, but has not previously been described in paediatric MS. A total of 24 consecutive children with newly diagnosed MS were prospectively assessed for bladder and bowel problems early after diagnosis. Five of 24 children (21%) showed LUTD during assessment. One of these patients did not report voiding complaints. This high prevalence of LUTD indicates that all recently diagnosed patients with paediatric MS should be evaluated early in their disease and treated for urinary problems in order to prevent potential damage to the upper urinary tract., (© The Author(s), 2015.)

- Abstract
Objective: To evaluate changes of the urethral pressure profile (UPP) after implantation of adjustable continence therapy (ProACT), a minimally invasive procedure in which 2 volume-adjustable balloons are placed periurethrally for treatment of male stress urinary incontinence. The working mechanism of the ProACT to achieve continence has not been fully understood. We hypothesized that successful treatment with ProACT improves urinary continence by inducing a significant increase in static urethral pressure., Materials and Methods: We included patients who underwent UPP before and after ProACT implantation. UPPs were initially performed with the Brown-Wickham water perfusion method and later with the T-DOC Air-Charged catheter method. Pre- and postoperative UPPs and International Prostate Symptom Scores were evaluated. UPP measurements of successfully (no or 1 precautionary pad per day) and unsuccessfully treated patients were compared., Results: Twenty-seven patients were included in the study; 23 patients were successfully and 4 patients were unsuccessfully treated. Maximum urethral closure pressure (MUCP) increased significantly from median 58.0 to 79.0 cmH2O in the successfully treated group (P = .001). Within the subgroup of unsuccessfully treated patients, MUCP did not change significantly (P = .715). The change in MUCP was statistically significantly different between the successful and unsuccessful group (P = .034). Total score of the International Prostate Symptom Scores did not change significantly after ProACT implantation (P = .097)., Conclusion: Successful treatment with ProACT is associated with a significant increase of MUCP. This implies that increased static urethral pressure contributes to the working mechanism of the ProACT device to achieve continence., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: We sought to establish the reliability and validity of the Dutch version of the Vancouver Symptom Score for Dysfunctional Elimination Syndrome for children with dysfunctional voiding and their parents., Materials and Methods: For this cross-sectional multicenter study the Vancouver Symptom Score for Dysfunctional Elimination Syndrome was translated and cross-culturally adapted to Dutch following a standardized process. Patients 16 years or younger with dysfunctional voiding and their parents were recruited at pediatric, pediatric urology and pelvic floor physical therapy outpatient clinics. The reference group consisted of children 6 to 16 years old without dysfunctional voiding and their parents. All groups completed questionnaires. The evaluated measurement properties included discriminative ability, internal consistency, test-retest reliability, interrater agreement, criterion validity using the Pediatric Incontinence Questionnaire and construct validity. A cutoff value for diagnosis of dysfunctional voiding was determined., Results: A total of 50 patients and 60 references and their parents were included in the study. The Vancouver Symptom Score for Dysfunctional Elimination Syndrome showed good discriminative ability. A moderate internal consistency was found (Cronbach alpha 0.37-0.55). Test-retest reliability was moderate to good, and interrater agreement demonstrated good correlation between children and parents (ICC 0.85, 95% CI 0.79-0.89). A weak correlation with the Pediatric Incontinence Questionnaire was found in patients and construct validity was confirmed. Cutoff scores for dysfunctional voiding were 11 and 9 for patients and parents, respectively., Conclusions: The Dutch Vancouver Symptom Score for Dysfunctional Elimination Syndrome displayed moderate to good reliability and validity properties for the patient and parent versions. Use of this instrument in clinical practice will support the assessment of dysfunctional voiding and facilitate international reporting of research results., (Copyright © 2016 American Urological Association Education and Research, Inc.

- Abstract
Introduction: An increased activity of the external urethral sphincter or pelvic floor muscles during voluntary voiding leads to dysfunctional voiding. Frequently reported symptoms are urinary incontinence, urinary tract infections and high post-void residuals. Dysfunctional voiding is a common problem in school-aged children and despite various treatment options, 10-40% of the children remain therapy-refractory., Objective: The aim of this study is to evaluate the effectiveness of Onabotulinum toxin-A (BTX-A) injections in the external urethral sphincter in children with therapy-refractory dysfunctional voiding., Patients and Methods: Patients with therapy-refractory dysfunctional voiding who have received BTX-A injections in the external urethral sphincter from 2010 to 2013 were analysed. Children with known neuropsychiatric disorders were excluded. All children had abnormal flow patterns and increased pelvic floor tone during uroflowmetry/EMG studies. They had received at least five sessions of urotherapy and two sessions of pelvic floor physical therapy prior to treatment. A total of 100 IU of BTX-A was injected in the external urethral sphincter at the 3, 9 and 12 o'clock positions. Our main outcome measures were urinary incontinence, recurrent urinary tract infections and post-void residual., Results: A total of twenty patients, of whom 16 girls, with a median age of 9 years (range 5-14) were treated with BTX-A. The median follow-up was 13 months (range 5-34). Post-void residual decreased by 75% after BTX-A, from a median of 47.5 ml (16.3-88.5 ml) to 0 ml (0.0-28.0 ml) (p = 0.001) Six patients had a post-void residual < 20 ml prior to treatment. After BTX-A sixteen patients had a post-void residual <20 ml (Figure). No significant changes in uroflowmetry results was seen. Sixteen children are no longer daily incontinent, of whom 9 became completely dry (p = 0.0001). Eleven patients suffered from recurrent urinary tract infections prior to treatment. After BTX-A five children remained infection free, while the other six experienced only one urinary tract infection during follow-up (p = 0.003). Fourteen patients received additional urotherapy after BTX-A. Repeat injections were necessary in four patients after initial satisfactory results, with repeated good clinical responses. Two children showed no improvement after first BTX-A injection. No serious adverse events were reported., Discussion: The results in this homogenous group of patients confirm the conclusions of previous studies in opting BTX-A in the external urethral sphincter to be a viable treatment option for the therapy-refractory group of patients with dysfunctional voiding. What is new, is that in most of our patients post-injection urotherapy was used to amplify the BTX-A effect. During our long-term follow-up the satisfactory results were sustained, similar to the results of the long-term follow-up presented by Vricella et al. [1]. The retrospective character and relative small sample size are limitations of this study., Conclusions: This study shows safe and persistent satisfactory results during our average 13-month follow-up in 90% of our patients with therapy-refractory dysfunctional voiding. A prospective study using validated and standardized measurements will be performed to affirm our results and evaluate the exact role of post-injection urotherapy., (Copyright © 2015 Journal of Pediatric Urology Company.

- Abstract
Background: Blood oxygen saturation (BOS) is decreased in a low-compliant, overactive obstructed bladder. The objective of this study is to determine the effect of Sildenafil (SC) on bladder function and BOS) in an in vivo animal model of bladder outlet obstruction., Methods: Thirty-two guinea pigs; sham operated (n = 8), sham operated + SC (n = 8), urethrally obstructed (n = 8) and urethrally obstructed + SC (n = 8) were studied during an 8 week period. BOS of the bladder wall was measured by differential path-length spectroscopy (DPS) before obstruction, at day 0, and at week 8. The bladder function was evaluated by urodynamic studies every week., Results: Before surgery and after sham operation all study parameters were comparable. After sham operation, bladder function and BOS did not change. In the obstructed group the urodynamic parameters were deteriorated and BOS was decreased. In the group obstruction + SC, bladder compliance remained normal and overactivity occurred only sporadic. BOS remained unchanged compared to the sham group and was significantly higher compared to the obstruction group., Conclusions: In an obstructed bladder the loss of bladder function is accompanied by a significant decrease in BOS. Treatment of obstructed bladders with SC yields a situation of high saturation, high bladder compliance and almost no overactivity. Maintaining the microcirculation of the bladder wall might result in better bladder performance without significant loss of bladder function. Measurement of BOS and interventions focussing on tissue microcirculation may have a place in the evaluation / treatment of various bladder dysfunctions.

- Abstract
Objective: To report clinical outcomes for laparoscopic pyeloplasty (LP) in children compared with open pyeloplasty (OP) and literature findings., Patients and Methods: In a prospective study, the outcomes of 57 consecutive transperitoneal LP in children from the age of 3 years were analyzed and compared with a matched historic control group of OP and with series of LP in the literature. Successful result was defined as resolution of symptoms, no conversion or re-operation, improved hydronephrosis, and/or improved renographic drainage., Results: Mean operative time was 177 (SD 50.5)min in the LP group and 108 (SD 25.6)min in the OP group (p < 0.001). Mean hospital stay was 1.2 (SD 0.46) days in the LP and 6.7 (SD 1.2) days in the OP group. Improvement in renographic drainage was observed more often after LP than after OP (98% vs 83%; p = 0.010). A successful result was reported in 56 (98%) LP and 54 (95%) OP (p = 0.298) patients. Our LP series demonstrates a high success rate compared to literature data., Conclusions: Our LP has a similar success rate and more often improved renographic drainage in comparison to OP. Furthermore, our LP demonstrates a shorter hospital stay and favorable outcomes compared to the literature. We thus regard LP as standard treatment for repair of ureteropelvic junction obstruction in children from the age of 3 years., (Copyright © 2012 Journal of Pediatric Urology Company.

- Abstract
Current diagnosis, follow-up and treatment of patients suffering from bladder dysfunction are mainly symptom-targeted. A recently recognized cause of continuing bladder function loss is a deteriorated bladder microvasculature. Incorporating this aspect into the clinical diagnostic toolbox may improve treatment results. Recent developments in the field of optical spectroscopy now allow for non-invasive measurement of microvascular blood oxygen saturation in living tissue. We have recently reported pre-clinical data that show that this marker can be successfully measured in an animal bladder. In the animal model the marker differentiated bladders with loss of function from those with normal function. In the present paper, we report on the first in vivo measurement of this marker in the human bladder, as proof of principle, in the muscle of bladders with a normal function., (Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

- Abstract
Purpose: Several studies suggest that hypoxia of the bladder wall contributes to bladder dysfunction but the exact relation between bladder function and blood oxygen saturation, a surrogate marker for hypoxia, is not known. We determined bladder wall blood oxygen saturation in vivo in an animal model of bladder outlet obstruction to establish the exact relation between blood oxygen saturation and bladder function., Materials and Methods: In 8 sham operated and 8 urethrally obstructed guinea pigs we measured blood oxygen saturation of the bladder wall by differential path length spectroscopy before surgery and 8 weeks postoperatively. Urodynamic investigations performed during the whole 8-week period provided data on bladder function., Results: Before surgery and 8 weeks after sham surgery blood oxygen saturation in the bladder wall was between 88% and 95% during filling. It decreased during voiding and returned to greater than 90% within 30 seconds. Eight weeks after obstruction saturation was significantly lower than in the sham operated group during filling and voiding. The decrease was positively related to bladder pressure during filling and voiding, and was more pronounced when overactivity was present. Local bladder contractions occurred without a measurable increase in bladder pressure but were associated with a decrease in saturation., Conclusions: A normal bladder maintains a high oxygen saturation level during filling. Bladder obstruction compromises this ability, especially when it involves overactivity. Local bladder contractions without a measurable increase in bladder pressure were associated with a decrease in blood saturation., (Copyright © 2011 American Urological Association Education and Research, Inc.

- Abstract
Purpose: The objective of this study was to evaluate the influence of propiverine-HCl (P4) and propiverine-N-oxide (P4NO), one of the major metabolites of P4, on bladder contraction in a standardized in vivo model. Additionally, salivary flow measurements enabled the evaluation of hyposalivation, one of the most predominant anticholinergic side effects., Materials and Methods: Ten male mini pigs were anesthetized. P4 (0.4 mg/kg b.w.) and P4NO (0.422 mg/kg b.w.) were administered intravenously. Bladder contractions were induced through sacral anterior root stimulation and cystometrogram evaluation was performed. For stimulation-induced salivary flow measurements, the lingual nerve was exposed for neurostimulation. The effects of P4 and P4NO on stimulation-induced bladder contraction and salivation were evaluated in 5 mini pigs, respectively., Results: In all experiments, for each animal reproducible intravesical pressure values (Pves) were elicited during sacral anterior root stimulation before administration of the study drug. After administration of P4, Pves decreased by 64% whereas P4NO decreased Pves by 28%. Inhibition of salivary flow with P4 and P4NO was 71 and 32%, respectively. Directly following intravenous administration of P4, a short-term and reversible period of mild fluctuations in heart rate was observed. Administration of P4NO revealed no changes in either heart rate, or blood pressure., Conclusion: All of the investigated parameters revealed less anticholinergic effects for P4NO compared to P4. Under the experimental conditions described above, it may be assumed that P4NO behaves as a substance with poor anticholinergic effects with respect to side effects. As expected, P4 showed anticholinergic effects on bladder contraction and salivation.

- Abstract
Aims: To determine if detrusor glycogen content in a bladder after removal of a urethral obstruction reflects the situation of bladder dysfunction as it existed during the period of obstruction., Methods: The glycogen content of the detrusor was scored using a Periodic Acid Schiff's (PAS) staining. It was related to the functional history of the bladder. Bladder tissue was obtained from a guinea-pig model for posterior urethral valves where animals had been obstructed for up to 10 weeks, de-obstructed and allowed to recover for 2--8 weeks. Bladder urodynamic function had been documented with multiple measurements for the complete period of obstruction and de-obstruction., Results: The degree of glycogen deposition in a bladder after de-obstruction correlated directly with bladder function during obstruction. The strongest glycogen deposition was found in bladders having experienced the highest pressures, most instabilities, lowest compliance and highest contractility. In contrast, the bladder glycogen content was not related to the function of the bladder at the day the tissue was obtained, except for a relation between high glycogen content and continuing low compliance., Conclusions: The glycogen content of a bladder reflects the history of bladder dysfunction, also when measured during a recovery period. This window on the functional history of a bladder may be of clinical value for picking out potential bad-responders to therapy in patients with incomplete data on bladder function during a previous period of bladder obstruction.

- Abstract
Aims: We examined the relation between the loss of bladder function during obstruction and the potential for recovery of function after de-obstruction., Methods: Guinea pigs received a partial urethral obstruction. Bladder pressure, urine flow rate, detrusor overactivity (DO), compliance and contractility were examined weekly for 2-4 weeks (short), 6-8 weeks (medium), or 9-12 weeks (long). Then the obstruction was removed and bladder function followed up to 7 weeks. The groups were compared to animals receiving only obstruction or a sham operation., Results: During obstruction the three de-obstruction groups and the obstruction group progressively lost bladder function. Flow rate remained stable, compliance decreased, pressure, contractility and DO increased. After de-obstruction the response in the three de-obstruction groups varied. In S, bladder pressure and compliance normalized, contractility initially increased then decreased towards high normal values, DO remained high normal and flow rate increased. In M, bladder pressure and DO decreased to above average normal levels. Compliance improved but did not normalize. Contractility initially stabilized, then decreased to just above the normal range. Flow-rate increased. In L, bladder pressure and DO decreased to high normal. Compliance did not improve. Contractility decreased directly after de-obstruction, stabilizing at an above normal level, flow-rate increased., Conclusions: The potential for functional recovery decreases with increasing loss of bladder function. At all stages of bladder dysfunction, voiding pressure appears to normalize after de-obstruction. However, contractility remains high and compliance low. Such a bladder may be more vulnerable to new events of outflow obstruction than a low contractile, normal compliant bladder., ((c) 2008 Wiley-Liss, Inc.)

- Abstract
Purpose: Oxybutynin is used clinically to lower intravesical pressure and detrusor overactivity. In vitro it inhibits stretch induced bladder smooth muscle cell proliferation. We tested whether oxybutynin also prevents hypertrophic bladder changes in vivo in a model of partial bladder obstruction., Materials and Methods: Subvesical obstruction was induced in immature guinea pigs by a silver ring around the urethra. Eight animals received 0.4 mg oxybutynin per kg body weight per day in 2 doses. Control groups were obstructed without oxybutynin treatment or sham operated. Urodynamic pressure flow studies were performed at 1-week intervals for 10 weeks in all animals under anesthesia with ketamine/xylazine. After 10 weeks the animals were sacrificed and the bladder was removed for structural analysis with periodic acid-Schiff stain, in which the number of glycogen granules was also scored as a measure of previous ischemia., Results: Compared to the sham treated group obstructed animals had significantly higher intravesical pressure and detrusor overactivity, lower compliance and increased contractility. Obstructed animals that received oxybutynin retained normal intravesical pressure, detrusor overactivity and compliance. Their bladder contractility increased as in obstructed animals. The oxybutynin group showed less collagen infiltration in the detrusor and fewer glycogen granules compared to those in obstructed animals., Conclusions: Our results demonstrate that oxybutynin has a protective effect on bladder function and structure. Prevention of hypertrophic and ischemic bladder changes is an argument for an early start of oxybutynin treatment in children with inborn neurogenic bladder dysfunction, such as spina bifida, or in patients with urethral valves.

- Abstract
Purpose: The objective was to validate an in vivo model for evaluation of pharmacological effects on bladder function taking the most predominant anticholinergic side effect (hyposalivation) into account. Therefore, two anticholinergic properties (propiverine hydrochloride and tolterodine-L(+)-tartrate) were used to test the in vivo model. Sacral anterior root stimulation (SARS) was performed to induce reproducible and standardized bladder contractions. To evaluate hyposalivation standardised salivavary flow measurements by stimulating the lingual nerve was performed in addition to SARS., Materials and Methods: 10 male mini pigs were anaesthetised. The carotid artery was cannulated for blood pressure measurement and the jugular vein for administration of propiverine 0.4 mg kg(-1) b.w. and tolterodine 0.06 mg kg(-1) b.w. For stimulation-induced salivary flow measurements both lingual nerves were exposed and a cuff electrode was placed around the nerves. The bladder was exposed and a cystostomy catheter was inserted to performed cystometrographic measurements during SARS., Results: In all experiments, for each animal reproducible intravesical pressure values (pves) and salivary flow rates were elicited during electrostimulation before administration of the drug. Bladder pressure: After administration of propiverine, neurostimulation-induced rise in pves had fallen by 60% from the initial value. After administration of tolterodine pves had fallen by about 50%. After additional administration of atropine pves decreased to about 15% of the initial value for both drugs. Salivation: After propiverine salivary flow had fallen by 61%. Inhibition of salivary flow under tolterodine was about 56%. Additional administration of atropine led in both drugs to a nearly complete blockade of salivation. Heart rate (HR) and blood pressure (BP): Directly following intravenous administration of both drugs, a short-term and reversible period of mild but significant fluctuations in HR was observed. There was also a slight but non-significant rise in blood pressure., Conclusions: This model allows comparative investigations of various drugs with bladder inhibitory properties in terms of acute efficacy and side effects.

- Abstract
Objectives: Endothelin (ET) is a strong constrictor of smooth muscle structures. The relevance of Endothelin-A receptors in the bladder was demonstrated in several in vitro studies. The aim of this functional study was to evaluate the acute effect of the selective ET-A-antagonist LU 302146 (LU) on neurostimulation-induced bladder contractions in vivo., Methods: Eight male mini pigs were anesthesized. The bladder was exposed and a double lumen catheter was inserted to perform intravesical pressure (pves) measurements. Laminectomy was performed for sacral anterior root stimulation (SARS) of S2. Four animals received the selective ET-A-antagonist LU, three atropine and one animal was treated with vehicle. Pves was recorded before and after drug administration as well as before and during neurostimulation. At the end of each LU trial, a supplementary application of 4 mg atropine was administered followed by a final SARS., Results: In all experiments reproducible pves values were elicited during electrostimulation before administration of the test substance. The selective ET-A-antagonist reduced stimulation-induced bladder contraction by a mean of 57%. Additional administration of atropine inhibited the detrusor contraction almost completely during SARS. The vehicle had no effect on bladder contraction., Conclusions: In the presented animal model, ET-1 inhibition with the selective ET receptor-A-antagonist LU 302146 decreases stimulation-induced bladder contraction in vivo. The results suggest that the selective ET-A antagonist LU acts on the atropine-resistant component of efferent detrusor activation since additional administration of atropine almost completely abolish detrusor contraction. This observation in addition to the involvement of ET-1 in bladder smooth muscle proliferation, raises the possibility that ET-receptor antagonists might be beneficial in patients with neurogenic bladder dysfunction or in patients with functional or anatomical BOO.

- Abstract
Objective: To report our experience with the percutaneous management of renal stone disease in children., Patients and Methods: The medical and radiological records of children up to 18 years old who were treated for renal calculi by percutaneous nephrolithotomy (PCNL) at our institution between March 1995 and April 2003 were reviewed. For stone removal a special paediatric 18 F access sheath was used., Results: In all, 26 PCNLs were used in 23 patients (10 boys and 13 girls, aged 1.7-16.8 years). The presenting symptoms were urinary tract infection, abdominal pain and/or haematuria. Of the 23 patients, 17 (75%) had associated metabolic disease or underlying urological anatomical abnormalities. Urinary tract infections were found in 15 patients (65%). The mean (range) stone burden was 6.0 (0.5-18.2) cm2, and the operative duration 127 (50-260) min. The primary stone-free rate was 58%, which increased to 81% after treating residual fragments. One blood transfusion was required and one patient developed urosepsis after PCNL, which was treated with antibiotics., Conclusion: PCNL is an effective alternative for treating renal stones in children, and is the treatment of choice for stones refractory to extracorporeal shock wave lithotripsy.
