The degree of change in erectile (EF) and ejaculatory function (EjF) according to validated questionnaires following anterior urethroplasty and different techniques is unclear.To investigate the evidence on EF and EjF evaluated via validated questionnaires following anterior urethroplasty.A systematic review (PROSPERO ID: CRD42021229797) of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The PubMed and CENTRAL databases were searched on February 1, 2021, with an updated search performed on December 1, 2021. Studies evaluating EF and/or EjF using validated questionnaires in men aged ≥18 yr following anterior urethroplasty were included.Overall, 29 studies (two randomised and 27 nonrandomised) were included. The questionnaire most commonly used to evaluate EF and EjF was the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ), respectively. The incidence of postoperative erectile dysfunction (ED) was 0-38% and the mean change in EF score according to the IIEF ranged from -4.0 to 2.5. The incidence of postoperative ejaculatory dysfunction (EjD) was 7.7-67% and the mean change in EjF score according to the MSHQ-EjD was 0.7-7.0. Meta-analyses revealed a mean difference of -0.87 (95% confidence interval [CI] -1.50 to -0.23; p = 0.008) in IIEF-EF score and 1.77 (95% CI 0.61-2.93; p = 0.003) in MSHQ-EjF score following anterior urethroplasty.EF and EjF may be affected following anterior urethroplasty and men should be counselled appropriately. Owing to the variation in questionnaires and cutoff scores used, EF and EjF outcomes following different urethroplasty techniques are heterogeneous, with limited data from randomised controlled trials. An agreement on questionnaires and cutoff scores should be established to allow consistent reporting. Future research should aim to investigate best approaches for minimising sexual dysfunction.Surgical repair of the urethra (urethroplasty) used to treat narrowing of the urethra (urethral stricture) may affect erectile and ejaculatory function. Different questionnaires and definitions are used to evaluate sexual function, so it is hard to compare data. The degree of disruption can be affected by different techniques and the severity of disease.

Urethral bulking agents are commonly used to manage female stress urinary incontinence (SUI) as they have been suggested to be safe, efficacious, and a minimally invasive surgical option. Bulkamid is a newer bulking agent that has been introduced and promoted in the market for use. It is non-particulate in nature with high tissue biocompatibility, and consequently, it is difficult to differentiate between Bulkamid and a periurethral cyst on magnetic resonance imaging (MRI). This, therefore, presents a diagnostic dilemma.Here we describe two cases with previous injections of Bulkamid referred to our Centre for management of a presumed periurethral diverticulum based on MRI findings. Both patients were reviewed and examined in outpatient clinics with MRI findings discussed at MDT, further imaging was required.We found that a limited noncontrast computed tomography (CT) pelvis, followed by a voiding cystometrogram (VCMG), and then a repeat limited noncontrast CT pelvis effectively differentiated between Bulkamid and these presumed periurethral diverticulae. The theory behind this was that during micturition, the contrast would pass through to the urethral diverticulum and appear as high-density (bright) material within the periurethral region (the pre-VCMG was required to prove that any high-density material was due to the contrast and not pre-existing high-contrast material).A CT scan done in conjunction with a VCMG is likely to be more effective in differentiating between Bulkamid and a true periurethral diverticulum than an MRI scan. Appropriate diagnostic evaluation of periurethral lesions can lead to time-saving and cost-effective patient management as this will bypass the need for unnecessary investigations and possible unwarranted surgical intervention.

Prevalence data on nocturnal polyuria (NP), nocturia caused by overproduction of urine during sleep, is primarily limited to men and varies by NP definition. This U.S.-representative epidemiological study of men and women ≥30 years old assessed the prevalence of NP.Consenting participants completed the baseline EpiNP (Epidemiology of Nocturnal Polyuria) survey (eg Lower Urinary Tract Symptoms Tool, comorbidities). All reporting ≥2 voids/night and a target of 100 random respondents reporting 0 or 1 void/night were asked to complete 3-day bladder diaries. NP was defined as nocturnal polyuria index (NPI)0.33 (NPI33) and nocturnal urine production90 ml/hour (NUP90). Extrapolated prevalence was stratified by sex and subgroups: idiopathic (without underlying causes), associated with overactive bladder (NPOAB), bladder outlet obstruction (NPBOO; men) and comorbidities. Voided volumes and timing, including first uninterrupted sleep period, were assessed by subgroup.A total of 10,190 individuals completed the baseline survey; mean age (range) was 54.4 (30-95). A total of 3,938 individuals were invited to complete the diary; 1,763 (49.3%) completed 3-day bladder diaries. Urine production (maximum nighttime volume, total volume, nocturnal urine production, nocturia index) was higher in both men and women with idiopathic NP and comorbidities. The median number of nighttime voids was greatest for NPBOO in men and NPOAB in women. Bother associated with nighttime voiding differed by NP subgroup but was highest in NPBOO for men (NPI33: 69.6%; NUP90: 71.1%) and NPOAB for women (NPI33: 67.5%; NUP90: 66.0%).This population-based NP prevalence study including men and women characterizes NP subgroups and provides insights into nocturia treatment by emphasizing factors influencing urine production versus factors influencing bladder capacity.

AIM: The aim of this study is to evaluate safety and efficacy of ASP8302, a novel positive allosteric modulator for the muscarinic M3 receptor (M3-PAM), in patients with underactive bladder (UAB).METHODS: A randomized, double-blind, placebo-controlled multicenter study was performed in adult male/female subjects with UAB, defined as incomplete bladder emptying (postvoid residual volume [PVR] > 100 ml) without significant bladder outlet obstruction and/or overactive bladder. Subjects were randomized (1:1) to receive 4-week oral once-daily administration of 100 mg ASP8302 or matching placebo. Primary endpoint was a change from baseline in PVR measured by catheterization after standardized bladder filling (PVRC2 ). Other endpoints included PVR and bladder voiding efficiency (BVE) measured in various ways, uroflowmetry, bladder diary, and questionnaires. Pressure-flow studies were performed in a subgroup.RESULTS: One hundred and thirty-five patients were randomized (ASP8302 group: 65 patients, placebo group: 70 patients). The median change in PVRC2 was -40.0 ml (ASP8302) versus -35.0 ml (placebo) and the difference between groups was -5.0 ml (p = 0.960). In males, functional and symptomatic outcomes improved, for example, maximum urine flow rate (Qmax ) and detrusor pressure at Qmax (Pdet.Qmax ) increased (mean difference in change ASP8302 vs. placebo: 3.8 ml/s, p = 0.031 and 12.7 cm H2 O, p = 0.034, respectively). Urinary incontinence episodes/24 h decreased in males with preexisting incontinence (mean difference: -0.35; p = 0.028). The incidence of adverse events was similar between study groups (ASP8302: 33.3%, placebo: 31.4%). In the included subjects, both baseline urine flow and bladder voiding pressure was low. Compared with PVR, simultaneous BVE measurements were more consistent between various methods (spontaneous vs. standardized bladder filling, catheterization vs. ultrasound [US]).CONCLUSIONS: ASP8302 was safe and well tolerated in patients with UAB identified by nonurodynamic clinical criteria, but it did not show efficacy in the primary endpoint. However, in males it showed improvement of symptoms and functional parameters. BVE (using US) is a more optimal outcome measure than PVR in UAB.

This case discusses the typical presentation, evaluation, and management options offered to male patients with urethral strictures. It uses three case-based scenarios to highlight some potential outcomes and some key differences in the approach and decision-making processes. It reviews the anatomy of the urethra and the pathophysiology of stricture disease and how its management has evolved over the years. It also discusses prognosis and rates of success of intervention.

Background Recommendations against prostate-specific antigen (PSA) testing in 2012 have increased advanced-stage diagnosis and prostate cancer–specific mortality rates. Objective To present the position of the European Association of Urology (EAU) in 2021 and provide recommendations for the use of PSA testing as part of a risk-adapted strategy for the early detection of prostate cancer. Evidence acquisition The authors combined their review of relevant literature, including the EAU prostate cancer guidelines 2021 update, with their own knowledge to provide an expert opinion, representing the EAU’s position in 2021. Evidence synthesis The EAU has developed a risk-adapted early prostate cancer detection strategy for well-informed men based on PSA testing, risk calculators, and multiparametric magnetic resonance imaging, which can differentiate significant from insignificant prostate cancer. This approach largely avoids the overdiagnosis/overtreatment of men unlikely to experience disease-related symptoms during their lifetime and facilitates an early diagnosis of men with significant cancer to receive active treatment. It also reduces advanced-stage diagnosis, thereby potentially reducing prostate cancer–specific mortality and improving quality of life. Education is required among urologists, general practitioners, radiologists, policy makers, and healthy men, including endorsement by the European Commission to adapt the European Council’s screening recommendations in its 2022 plan and requests to individual countries for its incorporation into national cancer plans. Conclusions This risk-adapted approach for the early detection of prostate cancer will reverse current unfavourable trends and ultimately save lives. Patient summary The European Association of Urology has developed a patient information leaflet and algorithm for the early diagnosis of prostate cancer. It can identify men who do not need magnetic resonance imaging or a biopsy and those who would not show any symptoms versus those with more aggressive disease who require further tests/treatment. We need to raise awareness of this algorithm to ensure that all well-informed men at risk of significant prostate cancer are offered a prostate-specific antigen test. Take Home Message A risk-adapted early prostate cancer detection strategy, incorporating prostate-specific antigen testing, multiparametric magnetic resonance imaging, risk calculators, and biomarkers, will avoid overdiagnosis/overtreatment of insignificant cancers and ensure early detection and treatment of significant cancers, thereby improving quality of life and reducing prostate cancer–related deaths.

Bladder pain syndrome is a clinical condition with many aspects to its presentation and numerous suggested treatments, many of which remain controversial. Reconstructive surgery should only be considered when all the conservative options have been exhausted and only after careful counselling. The purpose of this review is to demonstrate the current evidence in the surgical management of this disease, preparatory to which we have reviewed the surgical aspects. For medical treatment, the evidence base is of poor quality and based on case series. Nevertheless, in carefully selected patients after appropriate counselling, excellent results can be achieved both with total cystectomy and augmentation cystoplasty or a continent or incontinent diversion. We reviewed the various success rates of the treatments which are described. A multidisciplinary approach is essential to a successful outcome, and it is essential to consider not only the urological, but also broader medical and psychological consequences seen with bladder pain syndrome. Further research should focus on clearly categorizing the patients with well-defined clinical criteria to provide high-quality evidence to support the selection of the most effective treatment.

Background Overactive bladder (OAB) syndrome is a symptom complex affecting 12–14% of the UK adult female population. Symptoms include urinary urgency, with or without urgency incontinence, increased daytime urinary frequency and nocturia. OAB has a negative impact on women’s social, physical, and psychological wellbeing. Initial treatment includes lifestyle modifications, bladder retraining, pelvic floor exercises and pharmacological therapy. However, these measures are unsuccessful in 25–40% of women (refractory OAB). Before considering invasive treatments, such as Botulinum toxin injection or sacral neuromodulation, most guidelines recommend urodynamics to confirm diagnosis of detrusor overactivity (DO). However, urodynamics may fail to show evidence of DO in up to 45% of cases, hence the need to evaluate its effectiveness and cost-effectiveness. FUTURE (Female Urgency, Trial of Urodynamics as Routine Evaluation) aims to test the hypothesis that, in women with refractory OAB, urodynamics and comprehensive clinical assessment is associated with superior patient-reported outcomes following treatment and is more cost-effective, compared to comprehensive clinical assessment only. Methods FUTURE is a pragmatic, multi-centre, superiority randomised controlled trial. Women aged ≥ 18 years with refractory OAB or urgency predominant mixed urinary incontinence, and who have failed/not tolerated conservative and medical treatment, are considered for trial entry. We aim to recruit 1096 women from approximately 60 secondary/tertiary care hospitals across the UK. All consenting women will complete questionnaires at baseline, 3 months, 6 months and 15 months post-randomisation. The primary outcome is participant-reported success at 15 months post-randomisation measured using the Patient Global Impression of Improvement. The primary economic outcome is incremental cost per quality-adjusted life year gained at 15 months. The secondary outcomes include adverse events, impact on other urinary symptoms and health-related quality of life. Qualitative interviews with participants and clinicians and a health economic evaluation will also be conducted. The statistical analysis of the primary outcome will be by intention-to-treat. Results will be presented as estimates and 95% CIs. Discussion The FUTURE study will inform patients, clinicians and policy makers whether routine urodynamics improves treatment outcomes in women with refractory OAB and whether it is cost-effective. Trial registration ISRCTN63268739. Registered on 14 September 2017.

Background Urinary fistula (UF) is a global health problem but less common in well-resourced countries. Over the past decade there has been a trend toward managing UF in dedicated centres. Most of the evidence for surgical treatment is from individual case series, with few publications that involve high numbers. We describe the repair of recurrent and complex UF cases and outcomes in a tertiary referral setting. Objective To describe UF aetiology, repair techniques, and outcomes. Design, setting, and participants This is a retrospective study of a series of patients undergoing UF repair at a specialist unit. Outcome measurements and statistical analysis We describe the aetiology, cure rate, complications, and postoperative urinary incontinence rates for the series of UF cases. Results and limitations A consecutive series of 98 patients was identified, all of whom were tertiary referrals. Of these, 31 (31.6%) had at least one prior attempt at repair at another centre. The median age was 48 yr (interquartile range [IQR] 40–60.25). The median time from occurrence to repair was 12 mo (IQR 6–12). UF occurred most commonly following hysterectomy (48.0%), Caesarean section (9.2%), other gynaecological surgery (7.1%), and anti-incontinence surgery (7.1%). Complex fistulae (eg, repeat cases, radiation, ureteric involvement) comprised 41 of the cases (41.8%). Most patients with vesicovaginal fistula underwent repair via a transabdominal approach (70.4%). Tissue interposition was used in 96 cases (98%). There were no Clavien-Dindo grade >3 complications. Two patients (2%) had a persistent UF postoperatively. Two patients (2%) developed recurrence more than 2 yr after their initial repair, and both were successfully repaired at our centre. Twelve patients (12.3%) developed de novo overactive bladder, 22 (22.5%) developed stress urinary incontinence (13 had subsequent incontinence surgery), and two (2%) developed bladder pain (both had a subsequent cystectomy). Conclusions Despite a high rate of recurrent and complex UF, successful lasting closure was achieved in 96% of our cases. A minority of patients developed other problems such as de novo overactive bladder and stress urinary incontinence that may require further treatment. Patient summary Urinary fistula is an abnormal opening or connection in the urinary tract and is less common in well-resourced countries. As a consequence, management of this condition is more frequently undertaken at specialist units. Even patients with a complex fistula and those who have had multiple attempts at repair can experience a cure. Urinary leakage is a common complication after the operation but can be successfully managed with surgery., Take Home Message Despite a high number of complex and recurrent cases, we achieved a success rate in excess of 95% in the surgical management of genitourinary fistula. It is important that such cases are managed by teams of surgeons who are comfortable in undertaking both vaginal and abdominal approaches to repair.

Objective:Transvaginal excision of urethral diverticulum (UD) is the gold standard treatment for symptomatic women with UD. Complete UD excision can be challenging due to poor access to the surgical field, especially with proximal, circumferential and recurrent UD. Prone patient positioning has been suggested as an effective way of improving surgical access and vision compared to the traditional supine positioning. However, direct comparison of the two positions is yet to be performed. This study aimed to compare patients who underwent UD excision in prone and supine positions.Materials and Methods:Prospectively recorded data of 79 women undergoing urethral diverticulectomy between 2004 and 2017 in a single referral centre were reviewed. Patients were operated either in supine or prone positions based on the surgeon’s preference. Data collected included patient demographics, UD characteristics on magnetic resonance imaging, intraoperative details and postoperative outcomes. Operative time was calculated from the electronic theatre records starting from the entry of the patient into the operating room to their exit.Results:The mean patient age was 42.38 (±15.24) years. More than half of the patients had a recurrent UD at presentation (51.89%). The mean size of the diverticulum was 25.06 (±1.2) mm, and the mean operative time was 146.18 (±6.0) min. UD excision was undertaken in prone position in 50 (63.3%) and supine position in 29 (36.7%) patients. Patients in the prone position group were older and had relatively larger and proximal UD. In the multivariable analysis, it was found that a proximally located UD was the main indicator for undergoing surgery in the prone position.Conclusion:Despite longer operative times, prone patient positioning appears to be the preferred option for patients with larger and proximal UD, presumably because it offers better access to the surgical field.

Background Female urethral diverticula (UD) are an uncommon and often overlooked aetiology in women presenting with lower urinary tract symptoms, urethral pain, and recurrent urinary tract infection. With increasing awareness, appropriate imaging is more commonly undertaken with consideration given to surgical management. Objective The video presented demonstrates the technique for excising large and/or complex UD using a modified prone jack-knife position—a position that offers excellent surgical access and allows the surgeon to operate in a more ergonomic position. Design, setting, and participants A retrospective review of the data on patients undergoing excision of UD at a tertiary referral unit was performed. Surgical procedure Urethral and suprapubic catheters (±insertion of ureteric stents) were placed in supine position. UD excised in the modified prone jack-knife position (±placement of a Martius flap). Measurements Subjective cure rate, recurrence rate, rates of postoperative urinary incontinence, need for secondary incontinence procedure, and postoperative complications were measured. Results and limitations A total of 121 patients were operated on in the study period. The mean follow-up time was 10 mo (range 3–40). The most frequent presenting symptoms included a vaginal mass (n = 76, 63%), followed by dysuria (n = 72, 60%) and pelvic pain (n = 71, 59%). An identifiable aetiological factor was present in 45 patients, including traumatic vaginal delivery (18, 15%), prior periurethral surgery (17, 14%), and urethral dilatation (10, 8%). All patients underwent postvoiding magnetic resonance imaging (MRI) to confirm the diagnosis and plan surgery. UD ranged in maximum diameter from 8 to 48 mm, with a mean of 43 mm (standard deviation 9.24). The most common anatomical location was midurethral (55, 46%), followed by distal (36, 30%), proximal (25, 21%), and full length (5, 4%). Most UDs were single in configuration (74%), followed by multiloculated (15%), saddle shaped (7%), and circumferential (5%). On preoperative videourodynamics, 17 (14%) had stress urinary incontinence. UD excision was undertaken in the modified prone jack-knife position in all cases. A Martius flap was utilised in 36 (30%). The median postoperative postvoiding residual was 26 ml (interquartile range 0–40). In total, 88 (73%) patients were continent postoperatively and 16 (13%) experienced de novo stress urinary incontinence. Of the 37 with pre-existing stress incontinence symptoms, 20 (54%) were continent after operation. A total of 14 patients had subsequent autologous fascial sling at 6 mo. In total, five symptomatic recurrences occurred (4%); of these patients, three elected to undergo surgical excision, all of whom had symptom resolution and were continent after operation. A total of 11 patients (9%) experienced a Clavien-Dindo grade I–II complication within 90 d after operation. Five patients complained of dyspareunia, which resolved by 6 mo. Conclusions The modified prone jack-knife position facilitates excellent access for excision of both simple and complex UDs. This positioning of the patient is not widely recognised amongst urologists. Using this approach, there were low rates of symptomatic recurrence and de novo stress incontinence at medium-term follow-up. Associated urinary incontinence resolves in over half of patients following UD excision; hence, we advocate deferring any incontinence procedure until after the results of surgery are established. Patient summary Surgical removal of urethral outpouching (diverticula) in women is challenging due to its potential to damage the nearby sphincter muscle, which controls continence, or the urethra tube. Placement of patients on their front, rather than on their back, provides excellent access for the surgical removal of urethral diverticula. With this approach, we achieved excellent rates of cure and low rates of urinary incontinence at an average follow-up of 10 mo.

Aims To inform and guide patient-centred care for men with lower urinary tract symptoms (LUTS), by providing in-depth qualitative evidence regarding men's perspectives on treatment decision-making for LUTS. Methods An interview study of men recruited from 26 English urology departments. Purposive sampling captured surgical/nonsurgical treatment decisions, and diversity in demographics and symptom burden, in men who had urodynamics and those who did not. After diagnostic assessments, men were interviewed either pre-treatment or after LUTS surgery. Thematic analysis was conducted. Participants' descriptions of how LUTS treatment decisions were made were categorised as patient-led, doctor-led, or shared. Results A total of 41 men participated (25 pre-treatment, 16 post-surgery), ages 52-89. Twenty out of 41 described the treatment decision as shared with their consultant, 14 as doctor-led, and seven as patient-led. There was no obvious association between treatment decision-making style and patients' satisfaction with either clinicians' role in their decision or their treatment decision. Incomplete or rushed discussions and misperceptions of LUTS and its treatment were reported, indicating a risk of suboptimal decision-making support by clinicians. As well as clinician opinion, men's treatment decision-making was influenced by the results of urological assessments, comparing current symptoms with possible side-effects of surgery, and others' experiences and opinions. Conclusions Men with LUTS report and prefer different kinds of decision-making support from their clinicians, who must tailor their input to patients' preferences and needs. Patients' treatment decision-making involves multiple factors and can be challenging, and areas of inadequate clinician support were identified. Recommendations for patient-centred consultations about LUTS treatment are presented.

Context The nonspecific storage symptom complex overactive bladder (OAB) is an important clinical condition in functional urology. Until recently, pharmacological therapy comprised antimuscarinic drugs, but more recently beta 3 agonists have added to the available agents. Traditional reporting of efficacy and safety of these agents relies upon regulatory placebo-controlled studies. There remains no head-to-head comparison of existing agents in the contemporary literature. Contemporary conclusions on comparative efficacy and safety drawn from the use of these agents are based on systematic reviews of the literature and associated meta-analyses. Objective In this study, we used the analytical model of multicriteria decision analysis (MCDA) to compare contemporary pharmacotherapy for OAB. Evidence acquisition Efficacy and safety data from published, randomised, placebo-controlled trials of antimuscarinic antagonists, the beta 3 agonist, and the combination of an antimuscarinic and beta 3 agonist were used to populate the MCDA model. Evidence synthesis Experts assessed weights of the relative importance of favourable and unfavourable effects, which provided a common measure of benefits and safety that were combined in the MCDA model to give an overall ranking of the OAB drugs. Results When benefits are judged as more important than safety, fesoterodine 4 or 8 mg used in a flexible dosing pattern provides the most favourable therapeutic option, over a wide sensitivity analysis relating to benefits and harms. Conclusions In our analysis using an MCDA model, in both the flexible dosing pattern of fesoterodine and the solifenacin combination with mirabegron, the benefit-safety balance is better in terms of benefits and/or safety than any of the other available OAB drugs. Caution in interpretation of the data has to be expressed as the fesoterodine data are based on a flexible dosing regimen, which adds an additional dimension of personalising therapy. Patient summary Overactive bladder (OAB) is a common condition with a significant impact on the quality of life. Possible symptoms include the following: (1) urgency—a compelling desire to urinate, which is difficult to defer; (2) urgency urinary incontinence—urgency leading to incontinence episodes; (3) frequency—increased frequency of wanting to pass urine; and (4) nocturia—increase in instances of getting up at night to urinate. To date, the mainstay of therapy for OAB has been antimuscarinic drugs and, more recently, the beta 3 agonist mirabegron. Ten international experts in urology, obstetrics, gynaecology, healthy ageing, and data analysis compared the benefit-risk balance of 14 OAB drugs licensed in Europe. The experts considered the importance of a favourable effect on the above four symptoms and also potential for side effects, but only three of these side effects, constipation, dry mouth, and dizziness, showed clinically relevant differences among the six drugs they considered. The observations recorded here suggest interesting differences between drugs across a wide range of possible trade-offs between benefit and safety. The different recruitment criteria used for each study may influence the results seen, so they need to be treated with caution. Comparison of flexibly dosed fesoterodine studies with fixed-dose fesoterodine studies introduces an additional potential bias; definitive conclusions can be drawn only if enough comparable placebo-controlled flexible dosing studies with other drugs were available.

Mirabegron, a β3-adrenoreceptor agonist, is an alternative drug to antimuscarinics for overactive bladder (OAB) symptoms.To summarise safety and efficacy reporting of mirabegron treatment for OAB symptoms.Pooled data analysed from 10 phase 2-4, double-blind, 12-wk mirabegron monotherapy studies in adults with OAB who had received one or more doses of study drug.Mirabegron: 25 and 50mg; antimuscarinics: solifenacin (2.5, 5, and 10mg) and tolterodine extended release (4mg).Baseline OAB-related characteristics, intrinsic and extrinsic factors, and analyses by age (65 vs ≥65yr and75 vs ≥75yr) and sex were assessed. Solifenacin 2.5 and 10mg groups were not included in the efficacy analyses (small patient numbers). Safety was evaluated using the proportion of treatment-emergent adverse events. Efficacy variables were derived from bladder diaries (baseline and week 12).Baseline hypertension and diabetes were more frequent across treatment groups in the older versus younger age groups and in men versus women. Within sexes, frequencies were similar between treatment groups. Some differences were observed in baseline characteristics, including type of incontinence and medical history between sexes. No previously unreported safety concerns were identified. Improvements in efficacy (mean number of incontinence episodes/24h, micturitions/24h, urgency episodes/24h, volume voided/micturition, and nocturia episodes) versus placebo were observed in all treatment groups. Significant treatment-by-subgroup interactions included change from baseline in the mean number of incontinence episodes/24h by age (65 vs ≥65yr), nocturia by age (65 vs ≥65yr and75 vs ≥75yr), and urgency episodes by previous OAB medication.Data from this integrated database of 10 mirabegron studies reaffirm the safety and efficacy profiles of mirabegron, solifenacin, and tolterodine in adults of different age groups and sexes.Overactive bladder is a complex of symptoms including a compelling desire to pass urine that leads to increased frequency, which may lead to a degree of incontinence if you do not reach the toilet in time and may wake you from sleep. We pooled data from 10 different studies of mirabegron in patients with overactive bladder symptoms, and looked at the effect in the total number of patients who received the treatment, as well as in different age groups and between men and women. No new safety concerns were identified, and mirabegron improved the symptoms of overactive bladder.

Oral pharmacotherapy consisting of antimuscarinics, β3-adrenoreceptor agonists, or combinations of these agents forms the mainstay of overactive bladder (OAB) management.To evaluate the efficacy and safety of combination therapy in patients with OAB.A literature search was conducted in June 2018 using Embase, MEDLINE, and Cochrane databases via Ovid and relevant congress abstracts. Studies reporting the efficacy/safety of two antimuscarinics or a β3-adrenoreceptor agonist plus an antimuscarinic were included.Publications reported on clinical efficacy, safety, and health-related quality of life (HRQoL) for mirabegron (M) plus solifenacin (S) from three 12-wk randomised controlled trials (RCTs)-SYMPHONY, SYNERGY, and BESIDE-and a 12-mo RCT, SYNERGY II. SYMPHONY reported statistically significant improvements in clinical symptoms and HRQoL with combination therapy versus solifenacin 5 mg (S5) and placebo. In SYNERGY, there were consistent improvements in urinary incontinence (UI) episodes/24 h and micturitions/24 h (coprimary endpoints), and in secondary efficacy parameters with mirabegron 25 mg (M25) + S5 and mirabegron 50 mg (M50) + S5 versus respective monotherapies. In patients with an inadequate response to S5 monotherapy (BESIDE), greater improvements in UI (primary endpoint) were noted for M50 + S5 versus S5 (p = 0.001). Combination therapy was noninferior to solifenacin 10 mg (S10) for reduction in UI and superior to S10 for improvement in micturition frequency (p 0.001), and resulted in greater improvements from baseline in OAB-5 Dimension scores versus S5 and S10 (p 0.01). In SYNERGY II, clinically meaningful and sustained improvements in clinical outcomes were observed for M50 + S5 versus M50 or S5. Combination therapy was well tolerated in all four trials. The incidence of adverse events (AEs) was similar across groups, and there were no notable differences in the incidence of specific AEs. Positive efficacy outcomes were observed in five studies of dual antimuscarinic therapy (trospium + solifenacin).Mirabegron plus solifenacin provides effective, well-tolerated treatment for patients with OAB. Limited data for dual antimuscarinic therapy suggest a benefit in patients with moderate-to-severe symptoms.Overactive bladder (OAB) is treated with medicines called antimuscarinics, such as solifenacin, propiverine, or trospium, or another β-adrenoreceptor agonist medicine called mirabegron, which works in a different way. We looked at published scientific studies of patients with OAB treated with mirabegron plus solifenacin together, or with two antimuscarinics. We found that mirabegron plus solifenacin can help reduce symptoms and improve quality of life. Patients tolerate this treatment well, with few patients experiencing side effects.

Stress urinary incontinence (SUI) has been treated surgically with the midurethral sling but in recent years, this option has come under scrutiny and the risk-benefit balance continues to be reviewed. The low-risk alternative for women with uncomplicated SUI is the bulking agent, which aims to achieve continence through coaptation of the urethra. Two classes of bulking agents can be identified: those made from solid microparticles in an absorbable liquid or gel carrier (particulate agents) and those comprising a homogenous gel (non-particulates) that resists absorption. Polydimethylsiloxane®, carbon-coated zirconium oxide®, calcium hydroxyapatite® and polyacrylate polyalcohol copolymer® are currently marketed particulate agents. With the exception of calcium hydroxyapatite, the particles are non-degradable. Each agent achieves its long-term bulking effect through reactive changes around the persisting particles while the carrier volume is lost. Bulkamid® is a non-particulate agent with the bulking effect resulting from the volume of gel injected. The lasting network of fine fibers formed by the host tissue anchors the gel in situ. Foreign-body granulomas, erosion and migration/material extrusion and loss of bulk have been observed in connection with the particle-based products. Bulkamid may be mechanistically less liable to these events; however, there are minimal data directly comparing the two types of bulking agent. The question of durability is inevitable based on their differing modes of action.

The prevalence of nocturnal polyuria (NP), which is passing large volumes of urine during the main sleep period, has been investigated primarily in middle-aged to older men. There is thus a gap in the NP evidence base for women and for younger individuals.To estimate the prevalence of nocturia due to NP in the USA.This large epidemiologic study used a US population-representative sample of men and women aged ≥30 yr to assess the prevalence of NP (NCT04125186).Consenting participants completed an online survey (Lower Urinary Tract Symptoms Tool and comorbidities). All who reported two or more voids per night and 100 random respondents each reporting no or one void per night were asked to complete a 3-d bladder diary. Two NP definitions were used: nocturnal urine production90 ml/h (NUP90) and Nocturnal Polyuria Index0.33 (NPI33). Crude and population-adjusted prevalence results were calculated from completed diaries for the following subgroups by sex and age: idiopathic NP; NP with overactive bladder (NP-OAB) or bladder outlet obstruction (NP-BOO; men only); NP associated with other comorbidities; and no NP (did not meet the NPI33 or NUP90 definition).Among the 10,190 respondents who completed the survey, the mean age was 54.4 yr (range 30-95); 3,339 reported two or more nocturnal voids and 1,763 completed the 3-d diary (response rate 49.3%). The adjusted overall NP prevalence was 31.5% among men and 38.5% among women using the NPI33 definition, and 23.8% among men and 18.1% among women using NUP90. The adjusted idiopathic NP prevalence was lower among men (NPI33: 5.2%; NUP90: 1.4%) than among women (NPI33: 9.8%; NUP90: 4.0%). The prevalence of idiopathic NP decreased with age as NP associated with other possible causes increased with age in men (most common, BOO) and women (most common, OAB).This is the first population-based study of NP prevalence to include men, women, and young adults. NP is common; a multifactorial etiology should be considered, particularly as age increases.In this population-based US study, we examined the frequency of nighttime urination among men and women aged ≥30 y and older. We found that nighttime urination is common among men and women. Many conditions can lead to increased nighttime urination as people age.

INTRODUCTION AND OBJECTIVE:To assess the prevalence of nocturnal polyuria (NP) in a large epidemiologic study of a US population-representative sample of men (M) and women (W) ≥30 years (The EpiNP ...

Purpose of review Urethrotomy remains the first-line therapy in the treatment of a urethral stricture despite data showing no real chance of a cure after repeated urethrotomies. An anastomotic or an augmentation urethroplasty using oral mucosa can be offered to patients following failed urethrotomy. The potential for a tissue engineered solution as an alternative to native tissue has been explored in recent years and is reviewed in this article. Recent findings More than 80 preclinical studies have investigated a tissue-engineered approach for urethral reconstruction mostly using decellularized natural scaffolds derived from natural extracellular matrix with or without cell seeding. The animal models used in preclinical testing are not representative of disease processes seen with strictures in man. The available clinical studies are based on small noncontrolled series. Summary There is a potential role for tissue engineering to provide a material for substitution urethroplasty and work has demonstrated this. Further work will require a rigorous basic science programme and adequate evaluation of the material prior to its introduction into clinical practice. The research with tissue engineering applied to the urethra has not yet been resulted in a widely available material for clinical use that approaches the efficacy seen with the use of autologous grafts.

Context Female bladder outlet obstruction (fBOO) is a relatively uncommon condition compared with its male counterpart. Several criteria have been proposed to define fBOO, but the comparative diagnostic accuracy of these remains uncertain. Objective To identify and compare different tests to diagnose fBOO through a systematic review process. Evidence acquisition A systematic review of the literature was performed according to the Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. The EMBASE/MEDLINE/Cochrane databases were searched up to August 4, 2020. Studies on women ≥18 yr of age with suspected bladder outlet obstruction (BOO) involving diagnostic tests were included. Pressure-flow studies or fluoroscopy was used as the reference standard where possible. Two reviewers independently screened all articles, searched reference lists of retrieved articles, and performed data extraction. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). Evidence synthesis Overall, 28 nonrandomised studies involving 10 248 patients were included in the qualitative analysis. There was significant heterogeneity regarding the characteristics of women included in BOO cohorts (ie, mixed cohorts including both anatomical and functional BOO). Pressure-flow studies ± fluoroscopy was evaluated in 25 studies. Transperineal Doppler ultrasound was used to evaluate bladder neck dynamics in two studies. One study tested the efficacy of transvaginal ultrasound. The urodynamic definition of fBOO also varied amongst studies with different parameters and thresholds used, which precluded a meta-analysis. Three studies derived nomograms using the maximum flow rate (Qmax) and voiding detrusor pressure at Qmax. The sensitivity, specificity, and overall accuracy ranges were 54.6–92.5%, 64.6–93.9%, and 64.1–92.2%, respectively. Conclusions The available evidence on diagnostic tests for fBOO is limited and heterogeneous. Pressure-flow studies ± fluoroscopy remains the current standard for diagnosing fBOO. Patient summary Evidence on tests used to diagnose female bladder outlet obstruction was reviewed. The most common test used was pressure-flow studies ± fluoroscopy, which remains the current standard for diagnosing bladder outlet obstruction in women. Take Home Message The available evidence on diagnostic tests for female bladder outlet obstruction is limited and heterogeneous. The most common test used was video-urodynamics, which remains the current standard for diagnosing bladder outlet obstruction in women.
