Item does not contain fulltext, BACKGROUND: Interstitial cystitis/bladder pain syndrome (IC/BPS) patients are more susceptible to urinary tract infections (UTIs), likely worsening pre-existing symptoms. However, this receives limited attention in guidelines. This study aimed to explore the burden of UTIs on IC/BPS patients' quality of life and their healthcare. METHODS: Two quantitative retrospective database studies were conducted in cystoscopically proven IC/BPS patients: one compiled existing patient survey data (n = 217) from July 2021 to examine physical and emotional UTI burden, and the other used a patient file database (n = 100) from January 2020 to May 2022, focusing on UTI prevalence, healthcare use, urine cultures and antibiotic resistance. RESULTS: A delay in diagnosis was seen in 70% of patients, due to doctors confusing IC/BPS symptoms with UTIs. The UTI prevalence was over 50%; these patients also report anxiety for new UTIs (70%) and worsening of IC/BPS symptoms (60%). Additionally, for UTI+ patients, healthcare consumption was significantly increased in both studies. Antibiotic resistance (80% of cultures) and prophylactic antibiotic use were common. CONCLUSIONS: These findings highlight the burden of UTIs on quality of life in IC/BPS patients and the healthcare system. These results emphasize the need for improved UTI guidelines concerning diagnosis, management and prevention for IC/BPS patients to improve quality of life and care.

Item does not contain fulltext, BACKGROUND: Older patients (> 65 yr) suffering from overactive bladder (OAB) are more likely to have functional impairment and comorbidity than those without OAB. This article reviews available published studies and discusses how fesoterodine might meet the specific needs of the older OAB patient. METHODS: A comprehensive literature search was undertaken in order to evaluate fesoterodine safety in older OAB patients. RESULTS: Fesoterodine offers flexible dosing, allowing the clinician to balance risk and benefits according to the symptoms and preferences of the patient. Its balanced affinity for M2 and M3 muscarinic receptors may lead to its benefit on OAB symptoms. Its active metabolite is a P-gp substrate that is actively transported from the central nervous system (CNS), potentially avoiding adverse CNS effects. Fesoterodine can be used in mild or moderate hepatic or renal insufficiency and no dose adjustment is routinely required. Fesoterodine's benefit has been demonstrated in multiple clinical trials in older and medically vulnerable patients. Fesoterodine was rated as "beneficial" in the LUTS-FORTA classification due to its efficiency and tolerability in older patients. CONCLUSION: Here, the use of fesoterodine in older and vulnerable patients is summarized given the need to approach pharmacotherapy for OAB differently in older adults.

Item does not contain fulltext, WHAT IS KNOWN AND OBJECTIVE: Alpha-blockers have been associated with orthostatic hypotension (OH). We aimed to assess the prevalence of OH measured with beat-to-beat blood pressure monitoring in older male outpatients who used alpha-blockers for lower urinary tract symptoms (LUTS). In addition, we investigated associations of OH with duration of alpha-blocker use, concomitant medication use and comorbidity. METHODS: Cross-sectional explorative study in a urology outpatient clinic. Older white males ≥65 years using alpha-blockers for LUTS were included. Blood pressure responses to standing up from supine were recorded using a validated beat-to-beat blood pressure device (Finapres). Prevalence rates were derived from the beat-to-beat data to include OH measured between 60-110 s (OH), impaired recovery OH at 40 s (OH[40]), initial OH (IOH) and normal orthostatic response. Subgroups were defined based on duration of alpha-blocker use, polypharmacy, and Charlson comorbidity index (CCI), to obtain relative risks. RESULTS AND DISCUSSION: Sixty-five patients were included. Median age was 75 years (range 65-92). The prevalence of OH was 7.7% (n = 5). The prevalence of OH(40) was 16.9% (n = 11) and of IOH 38.5% (n = 25). Thirty-six patients (55.4%) had a normal orthostatic response. The relative risk of OH for the subgroup using ≥ 10 medications (n = 13) was 6.0 (95%CI 1.1-32.3). For the subgroup with multimorbidity (CCI ≥3, n = 11) this was 7.4 (95%CI 1.4-39.0). Recent initiation of alpha-blocker use (<3 months) did not increase OH risk (RR 0.6 [95%CI 0.1-5.1]). WHAT IS NEW AND CONCLUSION: The overall prevalence of OH was low and comparable to age-matched population prevalence, suggesting that the relative contribution of alpha-blockers to OH was small. However, OH risk significantly increased in patients with multimorbidity or polypharmacy. For these patients, the benefits of starting alpha-blockers for LUTS should be weighed against the increased risk of OH.

Contains fulltext : 225058.pdf (Publisher’s version ) (Closed access), CONTEXT: Coronavirus disease 19 (COVID-19) has changed standard urology practice around the world. The situation is affecting not only uro-oncological patients but also patients with benign and disabling conditions who are suffering delays in medical attention that impact their quality of life. OBJECTIVE: To propose, based on expert advice and current evidence where available, a strategy to reorganize female and functional urological (FFU) activity (diagnosis and treatment). EVIDENCE ACQUISITION: The present document is based on a narrative review of the limited data available in the urological literature on SARS-Cov-2 and the experience of FFU experts from several countries around the world. EVIDENCE SYNTHESIS: In all the treatment schemes proposed in the literature on the COVID-19 pandemic, FFU surgery is not adequately covered and usually grouped into the category that is not urgent or can be delayed, but in a sustained pandemic scenario there are cases that cannot be delayed that should be considered for surgery as a priority. The aim of this document is to provide a detailed management plan for noninvasive and invasive FFU consultations, investigations, and operations. A classification of FFU surgical activity by indication and urgency is proposed, as well as recommendations adopted from the literature for good surgical practice and by surgical approach in FFU in the COVID-19 era. CONCLUSIONS: Functional, benign, and pelvic floor conditions have often been considered suitable for delay in challenging times. The long-term implications of this reduction in functional urology clinical activity are currently unknown. This document will help functional urology departments to reorganize their activity to best serve their patients. PATIENT SUMMARY: Many patients will suffer delays in urology treatment because of COVID-19, with consequent impairment of their physical and psychological health and deterioration of their quality of life. Efforts should be made to minimize

Contains fulltext : 220577.pdf (Publisher’s version ) (Open Access), PURPOSE OF REVIEW: Overactive bladder syndrome (OAB) is a chronic condition, which can be treated by tibial nerve stimulation. The present review will focus on the technical aspects, advantages, drawbacks, and limitations of the latest available applications of posterior tibial nerve stimulation. RECENT FINDINGS: We describe the technical aspects of recent developed implants and techniques of tibial nerve stimulation in a transcutaneous, percutaneous, and minimal invasive way. All different treatment options have advantages and disadvantages based on type of surgery, energy transfer, impedance, treatment setting options, risk of migration, and patient usability, which are described in this review. Only devices with data that are publicly available were included. SUMMARY: New technologies are on their way in the field of tibial nerve stimulation for the treatment of OAB. Technical aspects are important to demonstrate safety and efficacy and user friendliness in order to obtain high acceptance of the various devices.

Contains fulltext : 225048.pdf (Publisher’s version ) (Closed access), PURPOSE: We evaluated the 3-year safety and efficacy of the BlueWind Medical RENOVA™ iStim system for the treatment of overactive bladder syndrome. MATERIALS AND METHODS: All patients who previously underwent implantation with the RENOVA system were offered continued participation. The primary long-term study end point was to evaluate the safety profile based on incidence of serious adverse events (system and/or procedure related), which was measured by the impact and frequency of serious adverse events. The secondary end points included clinical improvement compared to baseline and quality of life improvement compared to baseline at 36 months, which was measured by 3-day voiding diary and quality of life questionnaires at certain time points. RESULTS: Of the 34 patients with overactive bladder syndrome who previously underwent implantation with the RENOVA system 20 consented to continuation in this 3-year followup study. Mean patient age was 56.1 years and 80% (16) of the study cohort was female. The overall treatment success rate was 75% at 36 months in the per protocol (16) and the intent to treat (20) analyses. In total, 73% of the patients reported improvement in health related quality of life scores above the minimal important difference of 10 points. CONCLUSIONS: This 3-year followup study using the BlueWind RENOVA iStim system for the treatment of overactive bladder syndrome symptoms confirms the long-term good safety profile with no technical failures reported. Lasting treatment efficacy is mirrored by a sustained positive impact on patient quality of life.

Contains fulltext : 219864.pdf (Publisher’s version ) (Open Access), BACKGROUND: Percutaneous tibial nerve stimulation (PTNS) is used as a treatment to reduce the complaints of overactive bladder (OAB). Although it is rewarding therapy patients need maintenance treatment to preserve the beneficial effect. AIM: This real-life retrospective study was performed to assess the feasibility of PTNS adherence. MATERIALS & METHODS: All patients who underwent PTNS were retrospectively included. We analyzed the following: indication, kind of treatments (pharmacologic and third-line therapy) before and after PTNS treatment, time and reason for quitting therapy. Statistical analysis was done by performing competitive-risk analysis and Kaplan-Meier curves. Patients were categorized into four groups. Group 1: all patients; group 2: all patients on maintenance PTNS therapy (continuing after 12 weeks); group 3: patients on maintenance PTNS therapy excluding the following: (a) patients with initial good response who seized treatment due to death, (b) patient who successfully switched to transcutaneous stimulation, (c) patients who were cured of their OAB symptoms, or (d) patients who relocated; and group 4: group 3 but excluding those who stopped treatment because of nonmedical reasons (physical strain, inconveniencies associated with visiting the hospital). RESULTS: Four-hundred two patients (70% female) with a median age of 70 years underwent PTNS. Underlying treatment indications were: OAB-wet (54%) and OAB-dry (29%). The median follow-up (FU) of group 1 was 4 months. Fifty-seven percent (N = 228) of the patients received maintenance PTNS therapy. Median FU in group 4 was 46 months (range, 3-111 months). Over 40% of the maintenance patients stopped PTNS because of logistic reasons and physical strain during an FU time of 6 years. CONCLUSION: The real-world data described here with is in line with earlier published work in terms of the success rate of OAB treatment. However, over 40% quit their therapy due to nonmedical reasons.

Item does not contain fulltext, AIMS: To assess efficacy and safety as well as predictive factors of dry rate and freedom from surgical revision in patients underwent AUS placement. The artificial urinary sphincter (AUS) is still considered the standard for the treatment of moderate to severe post-prostatectomy stress urinary incontinence (SUI). However, data reporting efficacy and safety from large series are lacking. METHODS: A multicenter, retrospective study was conducted in 16 centers in Europe and USA. Only primary cases of AUS implantation in non-neurogenic SUI after prostate surgery, with a follow-up of at least 1 year were included. Efficacy data (continence rate, based on pad usage) and safety data (revision rate in case of infection and erosion, as well as atrophy or mechanical failure) were collected. Multivariable analyses were performed in order to investigate possible predictors of the aforementioned outcomes. RESULTS: Eight hundred ninety-two men had primary AUS implantation. At 32 months mean follow-up overall dry rate and surgical revision were 58% and 30.7%, respectively. Logistic regression analysis showed that patients without previous incontinence surgery had a higher probability to be dry after AUS implantation (OR: 0.51, P = 0.03). Moreover institutional case-load was positively associated with dry rate (OR: 1.18; P = 0.005) and freedom from revision (OR: 1.51; P = 0.00). CONCLUSIONS: The results of this study showed that AUS is an effective option for the treatment of SUI after prostate surgery. Moreover previous incontinence surgery and low institutional case-load are negatively associated to efficacy and safety outcomes.

Contains fulltext : 203279.pdf (publisher's version ) (Open Access), Aims: This study investigated user perception and adherence related to a hydrophilic-coated urinary catheter (LoFric(R) Origo), available for male patients who practice intermittent catheterization. Design: The study had a prospective observational design, including patients from 19 European hospitals. Methods: A total of 416 patients were eligible for the study; 179 experienced catheter users and 237 de novo. Two questionnaires were filled out, one describing background data and a second, 8 weeks later, evaluating catheter features. Results: The response rate for the second questionnaire was 88% (365 patients). Patients evaluating the new catheter showed a general satisfaction rate of 81% and 72% kept using it. The hygienic grip of the catheter was appreciated by 85% and the foldable feature by 67%. The results show that convenience, ease of use, and hygienic factors are patient-preferred features for a urinary catheter. These factors were confirmed for the evaluated hydrophilic-coated catheter.

Item does not contain fulltext, The use of polypropylene tapes for female stress urinary incontinence is still the treatment of choice in 2018. These tapes have proven efficacy with an acceptable success rate and an acceptable level of complications. These results can be achieved with a procedure that is less invasive than the alternatives in an ambulatory setting, with quick discharge from the hospital and speedy recovery.

Item does not contain fulltext, CONTEXT: Several drugs are approved and available for the treatment of lower urinary tract symptoms (LUTS) in men and women. However, the vast majority of available data, upon which the approval and recommendation in guidelines are based, considered only the role of the monotherapies and did not evaluate possible combination therapies. OBJECTIVE: This systematic review analyzes the efficacy and adverse events of combination therapies for male and female LUTS. EVIDENCE ACQUISITION: A systematic literature search in the PubMed/Medline, Web of Science, and Cochrane databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement to identify clinical trials, randomized controlled trials, meta-analyses, and guidelines on male and female LUTS combination therapy published from March 2012 to December 2017 for men (in order to update a previous men-focused work) and from January 1988 to December 2017 for women. A total of 58 papers were identified. EVIDENCE SYNTHESIS: The most studied combination therapy for the treatment of male LUTS is the alpha1-adrenoceptor antagonist/5alpha-reductase inhibitor combination. This combination seems to be more efficacious in terms of several outcome variables, in particular in men who have moderate-to-severe LUTS and are at risk of disease progression. Also in terms of nocturia improvements, this combination is significantly more effective than the monotherapy. The other often studied combination treatment, in both male and female patients with LUTS, was the combination of antimuscarinics (in particular solifenacin) and mirabegron. This combination seems to be more effective in comparison with the monotherapies with respect to urinary incontinence and urgency urinary incontinence episodes and several other objective and subjective parameters, without relevant increase of adverse events. The combination of hormone therapy and antimuscarinics in women with LUTS does not seem to be useful.

Contains fulltext : 202930.pdf (publisher's version ) (Closed access), INTRODUCTION: Parkinson's disease (PD) is a chronic multisystem disorder that causes a wide variety of motor and non-motor symptoms. Over time, the progressive nature of the disease increases the risk of complications such as falls and loss of independence, having a profound impact on quality of life. The complexity and heterogeneity of symptoms therefore warrant a holistic, multidisciplinary approach. Specific healthcare professionals, e.g. the movement disorders neurologist and the PD nurse specialist, are considered essential members of this multidisciplinary team. However, with our increasing knowledge about different aspects of the disease, other disciplines are also being recognized as important contributors to the healthcare team. Areas covered: The authors describe a selection of these relatively newly-recognized disciplines, including the specialist in vascular medicine, gastroenterologist, pulmonologist, neuro-ophthalmologist, urologist, geriatrician/elderly care physician, palliative care specialist and the dentist. Furthermore, they share the view of a person with PD on how patients and caregivers should be involved in the multidisciplinary team. Finally, they have included a perspective on the new role of the movement disorder neurologist, with care delivery via 'tele-neurology'. Expert commentary: Increased awareness about the potential role of these 'new' professionals will further improve disease management and quality of life of PD patients.

Contains fulltext : 200096.pdf (publisher's version ) (Open Access), Urgency is the cornerstone symptom of overactive bladder (OAB) syndrome, which is associated with reduced health-related quality of life (HRQoL) and affects patients with different profiles. We report here three clinical pictures of OAB: a male patient with mixed lower urinary tract symptoms (LUTS), a young woman with comorbidities, and an elderly woman with mixed urinary incontinence. The aim is to analyze the specificities of these real cases, to discuss what would be the most appropriate management, and how treatment with fesoterodine, an antimuscarinic agent with key pharmacological properties, might meet the patients' expectations. Relevant and constructive messages are drawn: urgency, the cornerstone symptom, should be given special attention; fesoterodine is effective and well tolerated in the elderly; before switching to another medication consider increasing the dosage of fesoterodine; the major goal of initial therapy is to meet patient expectations; and involving the patient in the treatment plan increases her/his adherence.

Item does not contain fulltext, BACKGROUND: Evidence-based guidelines for the management of neurological disease and lower bowel dysfunction have been produced by the International Consultations on Incontinence (ICI). These are comprehensive guidelines, and were developed to have world-wide relevance. AIMS: To update clinical management of neurogenic bowel dysfunction from the recommendations of the 4th ICI, 2009. MATERIALS AND METHODS: A series of evidence reviews and updates were performed by members of the working group. The resulting guidelines were presented at the 2012 meeting of the European Association of Urology for consultation, and modifications applied to deliver evidence based conclusions and recommendations for the scientific report of the 5th edition of the ICI in 2013. RESULTS: The current review is a synthesis of the conclusions and recommendations, including the algorithms for initial and specialized management of neurogenic bowel dysfunction. The pathophysiology is described in terms of spinal cord injury, multiple sclerosis, and Parkinson's disease. Assessment requires detailed history and clinical assessment, general investigations, and specialized testing, if required. Treatment primarily focuses on optimizing stool consistency and regulating bowel evacuation to improve quality of life. Symptom management covers conservative and interventional measures to promote good habits and assist stool evacuation, along with prevention of incontinence. Education is essential to achieving optimal bowel management. DISCUSSION: The review offers a pragmatic approach to management in the context of complex pathophysiology and varied evidence base.

Contains fulltext : 181610.pdf (publisher's version ) (Open Access), Overactive bladder (OAB) syndrome is a common, complex, and challenging condition. To assist the management of these patients, the European Association of Urology (EAU) updates its guidelines annually. This review reports the presentations from the symposium titled "Dealing with complex OAB patient profiles: in or out of the EAU guidelines?" held at the 32nd EAU Annual Congress in March 2017 in London. The symposium focused on three groups of OAB patients: women who may also suffer pelvic organ prolapse, stress urinary incontinence, the genitourinary syndrome of menopause (GSM); patients at risk of cognitive impairment; and elderly patients. The aim of the symposium was to determine how the 2017 EAU guidelines can best assist physicians, as well as to assess the benefits of fesoterodine in these patients. The EAU guidelines recommend antimuscarinic agents (grade A) for the medical treatment of OAB. In women, OAB is correlated with GSM, both of which are underdiagnosed and undertreated. Fesoterodine decreases OAB symptoms and the associated limitation of physical activity. A combination of fesoterodine and vaginal estrogens is appropriate for OAB associated with GSM. In patients at risk of cognitive impairment, prescribers should pay particular attention to the choice of medication. Fesoterodine is a Pgp substrate with limited ability to cross the blood-brain barrier, which may explain the lack of negative effects on the central nervous system observed in clinical trials of this agent. OAB should not be regarded as a normal consequence of aging. Fesoterodine has been extensively investigated in the elderly, and is the only anticholinergic drug licensed for OAB in this population, rated B (beneficial) according to the Fit for the Aged classification for lower-urinary-tract symptoms. The EAU guidelines are a valuable resource for physicians managing patients with OAB, and the pharmacological properties of fesoterodine offer credible clinical advantages in these three p

Contains fulltext : 177694.pdf (publisher's version ) (Closed access), AIM: Over the past few years, we have been doing an increasing number of revisions for artificial urinary sphincters (AUS) at our center. The study aims to investigate reason for this change in our practice. METHODS: Demographics and surgical outcomes of patients who received AUS in 2003-2014 at our center were retrospectively evaluated, and patients were contacted to check the current status of their AUS. The outcomes of the study were: percentage of revisions and explanation, survival, and the risk factors associated with these events. RESULTS: A total of 102 patients (72 years (30-87)) underwent 214 procedures: 99 primary implants, 11 secondary implants, 84 revisions, and 20 explantations-median follow-up was 54 months (5-146). The 5-years and 10-years revision-free survival for AUS were 47% and 23%, respectively. The 5 and 10 years explantation-free survival were 77% and 72%, respectively. The median time to revision for AUS implanted in 2010-2014 was shorter than in AUS implanted in 2003-2009 (6 vs. 13.5 months, P = 0.08). The percentage of AUS that were preceded by urethral surgery for incontinence was significantly higher in AUS implanted in 2010-2014 than in those implanted in 2003-2009 (19% vs. 63%, P = 0.001). The percentage of patients with AUS who received radiotherapy in the past 5 years was higher than in 2003-2009 (53% vs. 30%, P = 0.09). CONCLUSIONS: In modern urological practice, more exposure to RT and previous surgeries for incontinence are associated with increased risk for revision with decline in AUS survival.

Contains fulltext : 181594.pdf (publisher's version ) (Open Access), OBJECTIVE: To determine the ability of bladder wall thickness (BWT) in combination with non-invasive variables to distinguish patients with bladder outlet obstruction (BOO). PATIENTS AND METHODS: Patients completed the International Prostate Symptom Score (IPSS) questionnaire and prostate size was measured by transrectal ultrasonography (US). Pressure-flow studies were performed to determine the urodynamic diagnosis. BWT was measured at 250-mL bladder filling using transabdominal US. Recursive partition analysis (RPA) recursively partitions data for relating independent variable(s) to a dependent variable creating a tree of partitions. It finds a set of cuts of the dependent variable(s) that best predict the independent variable, by searching all possible cuts until the desired fit is reached. RPA was used to test the ability of the combined data of BWT, maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), IPSS, and prostate size to predict BOO. RESULTS: In all, 72 patients were included in the final analysis. The median BWT, voided volumes, PVR, mean Qmax, and IPSS were significantly higher in patients who had an Abrams/Griffiths (A/G) number of >40 (55 patients) compared to those with an A/G number of

Item does not contain fulltext, CONTEXT: Surgical nonautologous meshes have been used for several decades to repair abdominal wall herniae. Implantable materials have been adopted for the treatment of female and male stress urinary incontinence (SUI) and female pelvic organ prolapse (POP). OBJECTIVE: A consensus review of existing data based on published meta-analyses and reviews. EVIDENCE ACQUISITION: This document summarises the deliberations of a consensus group meeting convened by the European Association of Urology (EAU) and the European Urogynecological Association, to explore the current evidence relating to the use of polypropylene (PP) materials used for the treatment of SUI and POP, with reference to the 2016 EAU guidelines (European Association of Urology 2016), the European Commission's SCENIHR report on the use of surgical meshes (SCENIHR 2015), other available high-quality evidence, guidelines, and national recommendations. EVIDENCE SYNTHESIS: Current data suggest that the use of nonautologous durable materials in surgery has well-established benefits but significant risks, which are specific to the condition and location they are used for. Various graft-related complications have been described-such as infection, chronic pain including dyspareunia, exposure in the vagina, shrinkage, erosion into other organs of xenografts, synthetic PP tapes (used in SUI), and meshes (used in POP)-which differ from the complications seen with abdominal herniae. CONCLUSIONS: When considering surgery for SUI, it is essential to evaluate the available options, which may include synthetic midurethral slings (MUSs) using PP tapes, bulking agents, colposuspension, and autologous sling surgery. The use of synthetic MUSs for surgical treatment of SUI in both male and female patients has good efficacy and acceptable morbidity. Synthetic mesh for POP should be used only in complex cases with recurrent prolapse in the same compartment and restricted to those surgeons with appropriate training who are working i

Contains fulltext : 171608.pdf (publisher's version ) (Closed access), AIM: The molecular interactions between Transient Receptor Potential Vanilloid subtype 4 channels (TRPV4) and cell junction formation were investigated in the human and mouse urogenital tract. MATERIALS AND METHODS: A qualitative study was performed to investigate TRPV4 channels, adherence junctions (AJ's) and tight junctions (TJ's) in kidney, ureter and bladder tissues from humans and wild type and transgenic TRPV4 knockout (-/-) mice with immunohistochemistry, western blotting, immunoprecipitation and reverse-trasnscription-PCR. Cell junction formation in the wild type and TRPV4 knockout (-/-) mouse was evaluated with immunohistochemistry and Transmission Electron Microscope (TEM) techniques. RESULTS: TRPV4 channels are predominantly located in membranes of epithelial cells of the bladder, ureter and the collecting ducts of the kidney. There is a molecular interaction between the TRPV4 channel and the AJ. TEM evaluation showed that AJ formation is disrupted in the TRPV4 -/- mouse resulting in deficient intercellular connections and integrity of the epithelium. CONCLUSIONS: TRPV4 is believed to be a mechanoreceptor in the bladder. This study demonstrates that TRPV4 is also involved in intercellular connectivity and structural integrity of the epithelium.

Item does not contain fulltext, AIMS AND OBJECTIVES: To explore which factors determine successful intermittent catheterisation. BACKGROUND: Intermittent catheterisation is a safe, effective treatment and is associated with improved quality of life, although negative issues are reported. Factors which determine adherence are largely unknown. An additional qualitative study was conducted to gain insight into patient's experience with intermittent catheterisation in everyday life. DESIGN: A prospective multicentre study was conducted between March 2012-March 2013 with one year follow-up. METHODS: Patients with a variety of diagnoses referred to the outpatient clinic, >/=18 years, performed catheterisation at least once a day for >/=3 months were included. Data were obtained by patients' specific questionnaire Visual Analog Scale of quality of life regarding voiding problems, a questionnaire about catheterisation in daily practice, King's Health questionnaire, and a short questionnaire after one year. RESULTS: Of the 129 (72 male) patients, mean age 62 (22-86) years, seven died and 63 stopped, 32/63 (50%) due to recovered bladder function. Fifty-nine (47%) continued to perform catheterisation after one year. Forty-seven (86%) patients reported catheterisation had become part of their life or had a positive effect on their life. A weak correlation was found between increasing age and cessation of catheterisation. Visual Analogue Scale - score on quality of life improved for the total group. The King's Health questionnaire identified in the total group that the impact of the bladder problem in daily life, limitations in daily activities and negative emotions decreased over time. CONCLUSION: Adherence of successful intermittent catheterisation can be influenced negatively by increasing age. However, we think catheterisation should be considered as an option for older patients. We could not conform that if intermittent catheterisation was beneficial for the patient, it would positively influence adherenc

Item does not contain fulltext, AIMS AND OBJECTIVES: This study reports about the experiences of 11 patients in the Netherlands who use intermittent self-catheterisation to manage their symptoms. The aim of the study was to get insight in underlying barriers and facilitators for patients dealing with intermittent catheterisation in everyday life. BACKGROUND: Studies show that intermittent catheterisation has an impact on everyday life. A positive effect does not guarantee that patients maintain catheterisation over a longer period of time. After the implementation of a guideline, a quantitative study was performed to determine successful intermittent catheterisation. The patients of this study had previously taken part in this quantitative study. DESIGN: This is a qualitative multicentre study using semistructured in-depth interviews with 11 patients between March-May 2013. METHODS: Inclusion criteria included patients of a quantitative study (n = 124) with a variety of diagnoses referred to the outpatient clinic. Those who received instruction from the researcher and who at start of the study performed catheterisation

Contains fulltext : 165971.pdf (publisher's version ) (Open Access), A noncontact mapping system (EnSite) was used for electroanatomical mapping of the bladder simultaneously with pressure flow study in three women with lower urinary tract symptoms. We selected the periods of obvious detrusor activity. Data were processed to remove baseline drift, and an envelope of electrovesicography (EVG) data was created. The correlation coefficient for the correlation between between the EVG envelope and the detrusor pressure (Pdet) was calculated. Bladder geometry was successfully created in all 3 patients. Simultaneous recording of EVG and pressure flow data was successful in 1 patient. Scatter plots were made of the highest correlation coefficient, showing a positive correlation between the Pdet and the envelope, and negative correlation between abdominal pressure (Pabd) and the envelope. Minimal electrical activity could be observed. Significant weak to moderate correlation coefficients were found for the correlations between Pdet and EVG and between Pabd and EVG.

Background: The Actionable questionnaire is an 8-item tool to screen patients with multiple sclerosis (MS) for neurogenic bladder problems, identifying those patients who might benefit from urological referral and bladder-specific treatment. The original scoring yields a total score of 0 to 24 with cut-off point 6. A simplified scoring, yielding a total score of 0 to 8 with cut-off point 3, has been developed in urogynaecological patients, but has not been investigated in MS. Methods: One-hundred-and-forty-one MS patients completed the Actionable on two occasions. We compared the test performance of the simplified scoring with cut-off point 3 with that of cut-off point 2, using the original scoring with cut-off point 6 as a gold standard. The following measures were calculated: True Positives (TP), True Negatives (TN), False Positives (FP), False Negatives (FN), Sensitivity, Specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV), and Accuracy. The associations between positive test result and urological treatment, and bladder-specific drug treatment were calculated. Results: For cut-off point 3 the outcomes (Test 1, Test 2) were: TP 43.26 %, 40.88 %; TN 29.79 %, 32.85 %; FP 0.00 %, 0.00 %; FN 26.95 %, 26.28 %; Sensitivity 0.62, 0.61; Specificity 1.00, 1.00; PPV 1.00, 1.00; NPV 0.53, 0.55; Accuracy 0.73, 0.74; and for cut-off point 2: TP 59.57 %, 59.85 %; TN 26.95 %, 31.39 %; FP 2.84 %, 1.46 %; FN 10.63 %, 7.30 %; Sensitivity 0.85, 0.89; Specificity 0.90, 0.96; PPV 0.95, 0.98; NPV 0.72, 0.81; Accuracy 0.87, 0.91. Cut-off 3 completely prevented FP outcomes, but wrongly classified 26 % of the patients as negative (FN). Cut-off 2 reduced the FN to 7-10 %, with low FP values (2.84-1.46 %). With cut-off 2, the percentage of patients screened positive was higher in the Progressive group (75.00 %) than in the Relapsing Remitting group (56.25 %) (P∈=∈0.0331), which was not the case with cut-off 3. Only a positive test according to the original scoring

Subpubic cartilaginous pseudocyst is a rare degenerative lesion of pubic symphysis that may cause these symptoms. Materials and Methods. A 61-year- and 57-year-old women presented with symptoms of difficult micturition and dyspareunia. Physical examination revealed a painless smooth, rounded, firm, and cystic mass, at the anterior vaginal wall of about 4 cm width. The mass caused inward deviation of the external urethral meatus. Cystoscopy and MRI were done. Results. Cystoscopy of case 1 (61 y) demonstrated anterior external urethral compression with normal urethral mucosa. Cystoscopy was not possible in case 2 (57 y) because the urethra could not be entered under local anesthesia. MRI showed almost the same findings in both cases: midline, rounded, and cystic mass ~3 x 3 x 4 cm, anterosuperior to the urethra, and posteroinferior to the pubic symphysis, with normal features of the urinary bladder. Open surgical excision of theses lesions was performed in both patients. Histopathologic assessment of the specimen obtained from both patients showed degenerated hyaline with areas of fibrinous and mucoid degeneration, a picture suggestive of cartilaginous subpubic pseudocyst. After 11-month and 4-month followup of patients numbers 1 and 2, respectively, there is no evidence of local recurrence of the lesion, either clinically or radiologically and both patients void empty. Conclusions. Subpubic cartilaginous pseudocysts are rare benign lesions with only 13 cases were reported in the literature. Patients present with a spectrum of gynecological and/or urological manifestations. Sizable lesions severely compressing the urethra need surgical excision to restore the voiding function.

Item does not contain fulltext, INTRODUCTION: To evaluate the efficacy and safety of onabotulinumtoxinA for the treatment of neurogenic detrusor overactivity (NDO) in subpopulations of etiology (multiple sclerosis [MS] or spinal cord injury [SCI]) and concomitant anticholinergics (use/non-use). METHODS: Data were pooled from two double-blind, placebo-controlled, pivotal, phase 3 studies including a total of 691 patients with >/= 14 urinary incontinence (UI) episodes/week due to MS (n = 381) or SCI (n = 310). Patients received intradetrusor injections of onabotulinumtoxinA 200U (n = 227), 300U (n = 223), or placebo (n = 241). Change from baseline at week 6 in UI episodes/week (primary endpoint), urodynamics, quality of life (QOL), and adverse events (AEs) were assessed. RESULTS: Significant and similar reductions in UI episodes were observed regardless of etiology or anticholinergic use: at week 6, mean weekly decreases of -22.6 and -19.6 were seen in MS and SCI patients, respectively, and -20.3 and -22.5 in anticholinergic users and non-users, respectively, treated with onabotulinumtoxinA 200U. The 300U dose did not add to the clinical efficacy in any subpopulation. Similar proportions of patients achieved >/= 50% or 100% reductions in UI episodes in all subgroups. Improvements in maximum cystometric capacity, maximum detrusor pressure during first involuntary detrusor contraction, and QOL were significant in both etiologies and were independent of anticholinergic use. The most common AEs in all groups were urinary tract infection and urinary retention. CONCLUSION: Regardless of concomitant anticholinergic use or etiology, onabotulinumtoxinA significantly improved UI symptoms, urodynamics, and QOL in patients with UI due to NDO. OnabotulinumtoxinA was well tolerated in all groups.
