Abstract
INTRODUCTION AND HYPOTHESIS In the setting of recurrent female urethral stricture, urethroplasty offer the best chance of cure. However, which approach (dorsal or ventral) and which tissue (buccal mucosa, vaginal graft, vaginal flap) remain areas of controversy. In this article and accompanying video, we describe female urethroplasty with a supraurethral approach using a buccal mucosa graft. METHODS A stricture of 3 cm in length was observed in the mid urethra. A supraurethral semi-lunar incision was made and dissection was performed up to the stricture. A dorsal urethrotomy was performed and a 3 × 2 cm oral mucosal graft was harvested from the left cheek. The mucosal graft was anastomosed to both urethral edges with running sutures. The graft was fixed to the supraurethral tissue with quilting sutures. A urethral catheter and a suprapubic catheter were left in place for 3 weeks. RESULTS Following removal of the catheters, the patient was able to void satisfactorily with no incontinence. No complications were observed in the urethral area or at the graft harvest site. CONCLUSIONS Buccal mucosa graft urethroplasty with a supraurethral approach is a reliable method in the treatment of female urethral stricture.

Abstract
CONTEXT The complications of synthetic midurethral slings (MUSs) in women with stress urinary incontinence (SUI) have become a globally debated issue. OBJECTIVE To systematically review the short- and long-term complications of mesh slings reported in observational data compared with clinical trial data, to determine whether the complication rates from clinical trials reflects "real-world" observational data. EVIDENCE ACQUISITION PubMed and Cochrane Library were searched. Methods as detailed in Preferred Reporting Items for Systematic Reviews and Meta-analyses and Cochrane Handbook for Systematic Reviews of Interventions were followed. EVIDENCE SYNTHESIS Thirty registries/databases including 709 335 MUS procedures (1-22 yr of follow-up) were identified. MUS procedures were associated with intraoperative bladder perforation in 0.86-3.6%, urethral perforation in 0-0.1%, vascular injury in 0.04-0.1%, voiding lower urinary tract symptoms (LUTS) in 1.47-3.5%, vaginal exposure in 0.2-1.9%, and reoperation in up to 9% of cases. Forty-three randomised clinical trials were identified, including 6284 women who underwent MUS procedures and 2177 women who underwent other interventions (1-10 yr of follow-up). MUS procedures were associated with urinary tract perforation in 2.58%, vaginal injury in 1.43%, de novo voiding LUTS in 4.37%, de novo storage LUTS in 5.41%, mesh extrusion/exposure (vaginal/urinary tract) in 2.54%, dyspareunia in 2.26%, pain (pelvic/suprapubic/perineal) in 2.83%, and reoperation for complications required in 1.82% of cases. Meta-analyses of the randomised controlled trials revealed that retropubic MUSs were associated with more events of urinary tract perforation (risk ratio [RR] 9.81, 95% confidence interval [CI] 5.05-19.04, high certainty of evidence [COE]) and voiding LUTS (RR 1.57, 95% CI 1.19-2.07, high COE) than transobturator MUSs. MUSs were associated with more events of pain than mini-slings (RR 1.72, 95% CI 1.04-2.87, moderate COE). CONCLUSIONS Short- and long-term data on complications of polypropylene mesh used for female SUI are fairly comparable when using outcome data from well-designed clinical trials or from less structured prospective or retrospective registries. Comparisons have to be made with caution since the two systems of data collection are inherently incomparable. This knowledge should be incorporated in the discussion on how to implement polypropylene mesh for female stress incontinence. PATIENT SUMMARY In order to know whether mesh tapes used for treating stress incontinence work well and are safe, high-quality information is important. It appears that well-designed clinical studies give similar results to large registration databases. These data should be interpreted with caution in view of the different ways the information was collected. These results will help physicians and patients understand the risks of mesh tapes.

Abstract
INTRODUCTION Robotic ureteral reconstruction (RUR) has been widely used to treat ureteral diseases. To summarize the surgical techniques, complications, and outcomes following RUR, as well as to compare data on RUR with open and laparoscopic ureteral reconstruction. METHODS Our systematic review was registered on the PROSPERO (CRD42022309364) database. The PubMed, Cochrane and Embase databases were searched for publications in English on 06-Feb-2022. Randomised-controlled trials (RCTs) or non-randomised cohort studies with sample size ≥ 10 cases were included. RESULTS A total of 23 studies were included involving 996 patients and 1004 ureters from 13 non-comparative, and 10 retrospective comparative studies. No RCT study of RUR was reported. The success rate was reported ≥ 90% in 15 studies. Four studies reported 85-90% success rate. Meta-analyses for comparative studies showed that RUR had significantly lower estimated blood loss (EBL) (P = 0.006) and shorter length of stay (LOS) (P < 0.001) than the open approach. RUR had shorter operative time than laparoscopic surgery (P < 0.001). CONCLUSIONS RUR is associated with lower EBL and shorter LOS than the open approach, and shorter operative time than the laparoscopic approach for the treatment of benign ureteral strictures. However, further studies and more evidence are needed to determine whether RUR is more superior.

Abstract
PURPOSE Female representation at scientific conferences is crucial for encouraging women pursuing an academic career. Nevertheless, gender inequity at urological conferences is common place and women are often stereotyped choosing functional urology. However, there is no evidence whether female representation is higher in functional urology. This investigations aims to analyze gender representation at functional urology sessions. METHODS National and international urological congresses between 2019 and 2021 with a focus on functional urology and female urology sessions were evaluated. Congresses were categorized as national or international. Session type, topic, gender of chairs and speakers of the identified sessions were recorded. In addition, affiliation and medical specialty were collected for chairs. RESULTS A total of 29 congresses were evaluated. Out of a total of 2893 chairs and speakers, 1034 (35.7%) were women and 1839 (63.6%) were men. This represents an overall gender gap of 27.9% for functional urology sessions. No significant differences in gender representation between national and international congresses could be identified (p = 0.076). When considering gender distribution of chairs, the gap was more pronounced by 35.5%. Furthermore, men were more likely to be invited to be a speaker in plenary and podiums sessions. CONCLUSIONS Gender inequality is present in functional urology sessions. There is a need for greater efforts to achieve gender equality. An important step to remedy the situation is the inclusion of women in scientific program committees. Furthermore, support by the leadership of urological societies and academic departments is essential to herald a lasting change in gender inequality.

Abstract
INTRODUCTION 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. METHODS AND MATERIALS 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. RESULTS 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). CONCLUSION 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.

Abstract
The use of robot-assisted technology has been widely adopted in urological oncological surgery and its benefits have been well established. In recent years, robotic technology has also been used in several functional reconstructive and neuro-urology (FRNU) procedures. The aim of this review was to evaluate the current evidence in the use of robotic technology in the field of FRNU. We performed a PubMed-based literature search between July and August 2022. The keywords we included were 'robotic assisted', 'ureteric reimplantation', 'cystoplasty', 'ileal conduit', 'neobladder', 'sacrocolpopexy', 'colposuspension', 'artificial urinary sphincter', 'genitourinary fistula' and 'posterior urethral stenoses'. We identified the latest available evidence in the use of robotic technology in specific FRNU procedures such as the reconstruction of the ureters, bladder and urinary sphincter, urinary diversion, and repair of genitourinary prolapse and fistula. We found that there is a lack of prospective studies to assess the robotic-assisted approach in the field of FRNU. Despite this, the advantages that robotic technology can bring to the field of FRNU are evident, including better ergonomics and visual field, less blood loss and shorter hospital stays. There is therefore a need for further prospective studies with larger patient numbers and longer follow-up periods to establish the reproducibility of these results and the long-term efficacy of the procedures, as well as the impact on patient outcomes. Common index procedures and a standardized approach to these procedures should be identified to enhance training.

Abstract
CONTEXT The degree of change in erectile (EF) and ejaculatory function (EjF) according to validated questionnaires following anterior urethroplasty and different techniques is unclear. OBJECTIVE To investigate the evidence on EF and EjF evaluated via validated questionnaires following anterior urethroplasty. EVIDENCE ACQUISITION 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. EVIDENCE SYNTHESIS 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. CONCLUSIONS 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. PATIENT SUMMARY 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.

Abstract
CONTEXT Urethral stricture management guidelines are an important tool for guiding evidence-based clinical practice. OBJECTIVE To present a summary of the 2021 version of the European Association of Urology (EAU) guidelines on management of urethral strictures in females and transgender patients. EVIDENCE ACQUISITION The panel performed a literature review on these topics covering a time frame between 2008 and 2018 and used predefined inclusion and exclusion criteria for study selection. Key papers beyond this time period could be included as per panel consensus. A strength rating for each recommendation was added based on the review of the available literature and after panel discussion. EVIDENCE SYNTHESIS Management of urethral strictures in females and transgender patients has been described in a few case series in the literature. Endoluminal treatments can be used for short, nonobliterative strictures in the first line. Repetitive endoluminal treatments are not curative. Urethroplasty encompasses a multitude of techniques and adaptation of the technique to the local conditions of the stricture is crucial to obtain durable patency rates. CONCLUSIONS Management of urethral strictures in females and transgender patients is complex and a multitude of techniques are available. Selection of the appropriate technique is crucial and these guidelines provide relevant recommendations. PATIENT SUMMARY Although different techniques are available to manage narrowing of the urethra (called a stricture), not every technique is appropriate for every type of stricture. These guidelines, developed on the basis of an extensive literature review, aim to guide physicians in selecting the appropriate technique(s) to treat a specific type of urethral stricture in females and transgender patients. TAKE HOME MESSAGE: Although different techniques are available to manage urethral strictures, not every technique is appropriate for every type of stricture. Management of urethral strictures in females and transgender patients is complex and a multitude of techniques are available. Selection of the appropriate technique is crucial and these guidelines provide relevant recommendations.

Abstract
Subfertility is a risk factor for testicular cancers (TT), and conversely, TT may induce subfertility due to local and regional toxic effects. We aimed to identify the association between TT characteristics and pre-orchidectomy azoospermia. A systematic review of the literature was performed according to the PRISMA checklist. Overall, eight non-randomised studies involving 469 men with TT (azoospermia, n = 57; no azoospermia n = 412) were included in the qualitative analysis. Bilateral TT (12.3% vs 2.9% in non-azoospermia), non-seminoma germ cell tumours (6.4% vs 1.9%), germ cell neoplasia in-situ (GCNIS) (11.1% vs 1.2%), stage 2-3 disease (22.2% vs 0%), Sertoli Cell only (SCO) on biopsy (60% vs 37.5%) and a history of undescended testis (UDT) (66.7% vs 50%) were more common in azoospermic men. FSH levels are higher (18.7-23.2 mIU/L vs <0.1-8 mIU/L in non-azoospermia), testosterone is lower, and testis size are smaller (lower range 1 mL vs 10 mL) in men with azoospermia. Leydig cell tumours and hyperplasia were only detected in men with azoospermia. In summary, bilateral TT, GCNIS, higher tumour stage, smaller testes, SCO and history of UDT may have direct effects on spermatogenesis. Small testis, raised FSH and low testosterone may reflect reduced testicular function in azoospermic men. Performing a pre-orchidectomy semen analysis is important to identify those with azoospermia or severe oligospermia in order to plan for cryopreservation or onco-TESE in young men who wish to conceive.

Abstract
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.

Abstract
CONTEXT Urethral stricture management guidelines are an important tool for guiding evidence-based clinical practice. OBJECTIVE To present a summary of the 2021 European Association of Urology (EAU) guidelines on diagnosis, classification, perioperative management, and follow-up of male urethral stricture disease. EVIDENCE ACQUISITION The panel performed a literature review on the topics covering a time frame between 2008 and 2018, and using predefined inclusion and exclusion criteria for the literature. Key papers beyond this time period could be included if panel consensus was reached. A strength rating for each recommendation was added based on a review of the available literature after panel discussion. EVIDENCE SYNTHESIS Routine diagnostic evaluation encompasses history, patient-reported outcome measures, examination, uroflowmetry, postvoid residual measurement, endoscopy, and urethrography. Ancillary techniques that provide a three-dimensional assessment and may demonstrate associated abnormalities include sonourethrography and magnetic resonance urethrogram, although these are not utilised routinely. The classification of strictures should include stricture location and calibre. Urethral rest after urethral manipulations is advised prior to offering urethroplasty. An assessment for urinary extravasation after urethroplasty is beneficial before catheter removal. The optimal time of catheterisation after urethrotomy is <72 h, but is unclear following urethroplasty and depends on various factors. Patients undergoing urethroplasty should be followed up for at least 1 yr. Objective and subjective outcomes should be assessed after urethral surgeries, including patient satisfaction and sexual function. CONCLUSIONS Accurate diagnosis and categorisation is important in determining management. Adequate perioperative care and follow-up is essential for achieving successful outcomes. The EAU guidelines provide relevant evidence-based recommendations to optimise patient work-up and follow-up. PATIENT SUMMARY Urethral strictures have to be assessed adequately before planning treatment. Before surgery, urethral rest and infection prevention are advised. After urethral surgery, x-ray dye tests are advised before removing catheters to ensure that healing has occurred. Routine follow-up is required, including patient-reported outcomes. These guidelines aim to guide doctors in the diagnosis, care, and follow-up of patients with urethral stricture.

Abstract
The rate of burnout among physicians appears to be on the rise and urologist are no exception. In fact, urology appears to be one of the specialties most affected, with European urologists reporting burnout rates of up to 54% and those working in the United States up to 68%.Herein, we review the relatively few studies looking at burnout in European urologists to estimate its prevalence and discuss what could be done to reverse the trend. A total of seven studies were identified assessing burnout in urologists in Europe and Turkey. While the rates vary (9.3-68%), they indicate that burnout is prevalent within urology, with data from other studies suggesting there is a rising trend. Although the topic has been studied for many years, with an increased focus in the last decade, little seems to have been done to improve the situation.

Abstract
OBJECTIVE To present a summary of the 2021 version of the European Association of Urology (EAU) guidelines on management of male urethral stricture disease. EVIDENCE ACQUISITION The panel performed a literature review on these topics covering a time frame between 2008 and 2018, and used predefined inclusion and exclusion criteria for the literature to be selected. Key papers beyond this time period could be included as per panel consensus. A strength rating for each recommendation was added based on a review of the available literature and after panel discussion. EVIDENCE SYNTHESIS Management of male urethral strictures has extensively been described in literature. Nevertheless, few well-designed studies providing high level of evidence are available. In well-resourced countries, iatrogenic injury to the urethra is one of the most common causes of strictures. Asymptomatic strictures do not always need active treatment. Endoluminal treatments can be used for short, nonobliterative strictures at the bulbar and posterior urethra as first-line treatment. Repetitive endoluminal treatments are not curative. Urethroplasty encompasses a multitude of techniques, and adaptation of the technique to the local conditions of the stricture is crucial to obtain durable patency rates. CONCLUSIONS Management of male urethral strictures is complex, and a multitude of techniques are available. Selection of the appropriate technique is crucial, and these guidelines provide relevant recommendations. PATIENT SUMMARY Injury to the urethra by medical interventions is one of the most common reasons of male urethral stricture disease in well-resourced countries. Although different techniques are available to manage urethral strictures, not every technique is appropriate for every type of stricture. These guidelines, developed based on an extensive literature review, aim to guide physicians in the selection of the appropriate technique(s) to treat a specific type of urethral stricture.

Abstract
CONTEXT Four techniques for graft placement in one-stage bulbar urethroplasty have been reported: dorsal onlay (DO), ventral onlay (VO), dorsolateral onlay (DLO), and dorsal inlay (DI). There is currently no systematic review in the literature comparing these techniques. OBJECTIVE To assess if stricture recurrence and secondary outcomes vary between the four techniques and to assess if one technique is superior to any other. EVIDENCE ACQUISITION The EMBASE, MEDLINE, and Cochrane Systematic Reviews-Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane HTA, DARE, HEED) databases and ClinicalTrials.gov were searched for publications in English from 1996 onwards. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), observational studies (cohort, case-control/comparative, single-arm), and case series with ≥20 adult male participants were included. EVIDENCE SYNTHESIS A total of 41 studies were included involving 3683 patients from one RCT, four NRCSs, and 36 case series. Owing to the overall low quality of the evidence, a narrative synthesis was performed. CONCLUSIONS No single technique appears to be superior to another for bulbar free graft urethroplasty. Both DO and VO are suitable for bulbar augmentation urethroplasty, with a ≤20% recurrence rate over medium-term follow-up. No recommendations can be made regarding DI or DLO techniques owing to the paucity of evidence. Secondary outcomes including sexual function, and complications are infrequently reported. Recurrence rates deteriorate in the long term for both DO and VO procedures. PATIENT SUMMARY We reviewed the evidence for four different skin-graft techniques used to repair narrowing of a section of the urethra (bulbar urethra, under the scrotum and perineum) in men. Two of the techniques seem to give consistent results, with recurrence rates lower than 20%. Recurrence rates increase over time, so patients should continue to monitor their symptoms. There is poorer reporting of other outcomes such as sexual function, urinary symptoms, and complications, and it is possible that these occur more frequently than the current data suggest.

Abstract
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.

Abstract
The role of surgery in the management of bladder pain syndrome is unclear; particularly the optimum surgical approach. Treatment refractory patients should be managed in a multi-disciplinary setting including psychological support. Further prospective studies using validated assessments and clear diagnostic criteria would be useful to guide patient selection.

Abstract
CONTEXT Detrusor underactivity (DUA) is a common but relatively under-researched bladder dysfunction. Underactive bladder (UAB) is the symptom-based correlate of DUA. Recently, there has been renewed interest in this topic. OBJECTIVE To systematically review and summarise the most recent literature and discuss this in the context of what is already known. EVIDENCE ACQUISITION A systematic review of the literature was performed in December 2017 using Medline and Scopus databases. Separate searches of each database used a complex search strategy including "free text" protocols. Search terms included "underactive bladder", "detrusor underactivity", "acontractile bladder", "detrusor failure", "detrusor areflexia", "atonic bladder", "chronic retention", and "impaired bladder contractility". EVIDENCE SYNTHESIS The initial search retrieved a total of 1690 studies; of these 44 were included in the final analyses. CONCLUSIONS Although there has been an expansion in the literature concerning all aspects of DUA and UAB, knowledge on its epidemiology and aetiopathogenesis is still lacking; there remains a need to develop accurate reproducible diagnostic criteria and effective treatments, in particular drug therapies. PATIENT SUMMARY Recently, there has been renewed interest in underactive bladder with expanding research in this area. The lack of simple, reproducible, noninvasive diagnostic criteria has precluded an accurate estimation of the magnitude of the problem. Recent studies have highlighted the potential role of impaired bladder blood supply in causing bladder underactivity.

Abstract
Penile paraffinoma is a rare cause of penile mass that can occur following injection of liquid paraffin, performed illicitly for penile augmentation. Over the past 2 yr, we have observed an increasing number of cases presenting with the complications of penile paraffinoma; three patients of central European origin have required inpatient treatment at our institution and posed a significant management dilemma. This mini-review aims to review the literature on the aetiopathogenesis, clinical features, diagnosis, and management of penile paraffinoma. A systematic search of PubMed and Scopus was performed with 10 case series and 26 case reports identified between 1956 and 2017. A total of 124 cases, with a mean age of 36.29 yr, were identified. The majority originated in Korea, and the most common injected material was liquid paraffin (80.6%). Patients presented with pain/swelling, ulceration/fistulae, and penile deformity. The majority required surgical excision of paraffinoma followed by reconstruction with a variety of procedures including split skin grafting, scrotal skin flap reconstruction, and prepuce grafting. Mean duration of follow-up was 15.8 mo. Penile paraffinoma remains a rare presentation; however, it can present management difficulties. We have had an increase in cases, with three patients presenting with complications following injection of paraffin in our unit in the past 2 yr. Definitive management includes surgical excision and reconstruction as required with early involvement of plastic surgeons. There may be a role for conservative management; however, long-term outcomes are unclear. There may be a need for targeted preventative measures through public health agencies in communities where the practice is more prevalent. PATIENT SUMMARY: Penile paraffinoma can occur following injection of liquid paraffin or similar substances, generally used by non-healthcare personnel for the purpose of penile augmentations, and can cause significant pain, ulceration, and penile deformity. Definitive management includes surgical excision with reconstruction as required. Prevention of its use through awareness and education may be required in communities where the practice is more common.

Abstract
BACKGROUND Surgery for stress urinary incontinence (SUI) has been dominated recently by synthetic midurethral tapes. Increasing recognition of serious complications associated with nonabsorbable polypropylene mesh has led to resurgence in interest in alternative approaches, such as the autologous fascial sling (AFS). Despite being an efficacious and durable option in women with recurrent and complex SUI, there has been a reluctance to consider AFS in women with primary SUI due to a perception that it is only appropriate for treating patients with intrinsic sphincter deficiency (ISD) and is associated with high rates of urinary retention and de novo storage symptoms. OBJECTIVE The video presented demonstrates the technique for a loosely applied midurethral AFS. In contrast to AFS applied at the bladder neck, this technical modification in patients who demonstrate primary SUI without ISD avoids high rates of de novo storage symptoms and urinary retention. DESIGN, SETTING, AND PARTICIPANTS A retrospective review of data on patients undergoing AFS at a tertiary referral unit. SURGICAL PROCEDURE AFS placement in a "loose" fashion using a short length of fascia suspended on a suture bilaterally at the midurethral level rather than at the bladder neck and only using more tension in patients with ISD. MEASUREMENTS Subjective cure rate, rates of postoperative storage symptoms, and urinary retention necessitating intermittent self-catheterisation (ISC). RESULTS AND LIMITATIONS A total of 106 patients underwent AFS; the mean follow-up period was 9 mo. The mean age was 52.6 (range 24-83) yr. In total, 46.2% had primary SUI, whilst all of the remaining 53.8% had undergone prior surgical intervention. Overall subjective cure occurred in 79.2% of patients; a further 15.1% described significant subjective improvement in symptoms, whilst 5.7% reported no change in symptoms. In those with primary SUI, rates of subjective cure, improvement, and nonresolution of symptoms were 87.8%, 12.2%, and 0%, respectively. In individuals with prior surgical intervention, rates of subjective cure, improvement, and nonresolution of symptoms were 72.0%, 17.5%, and 10.5%, respectively. De novo storage symptoms occurred in 8.2% of those with primary SUI compared with 14.0% of those with prior surgical intervention. Only 2.0% patients with primary SUI needed to perform ISC beyond 2 wk compared with 10.5% of those after prior surgery. CONCLUSIONS A midurethral AFS appears to be effective and safe both in women with primary SUI who want to avoid the placement of permanent material and its attendant risks, and in more complex cases where this is less appropriate. PATIENT SUMMARY A graft taken from the covering of the abdominal muscle or the outer aspect of the thigh is an alternative to a synthetic vaginal mesh in women who have stress urinary incontinence requiring surgical treatment. Placing the graft loosely at the midpoint of the urethral tube, rather than at the bladder neck, reduces the risk of postoperative voiding difficulty and overactive bladder symptoms. Long-term data have suggested an outcome at least as good as a synthetic nonabsorbable tape without the potential for sling erosion into adjacent structures, as it avoids the use of nonabsorbable material.

Abstract
OBJECTIVE To describe the surgical approach and outcomes in the treatment of adult patients with complications of childhood hypospadias surgery, as such patients present a significant reconstructive challenge due to the combination of anatomical and cosmetic deformity, which often results in major functional and psychosexual sequelae. PATIENTS AND METHODS We analysed prospectively collected data on 79 adults with complications of childhood hypospadias surgery, who were operated on between 2004 and 2016. Of the 79 patients, 48 underwent a two-stage urethroplasty using a buccal mucosa graft, and 31 underwent a one-stage distal urethroplasty. RESULTS Patients were followed up using flexible cystoscopy (every 6-9 months). The mean (range) follow-up was 48 (12-96) months. Of the 48 patients who underwent a two-stage repair, eight (16%) needed a revision of the first-stage graft. In total, nine of the 48 patients (16%) developed fistula requiring closure after the second stage; all but one was closed successfully on the first attempt, whilst one required two attempts before closure. Only two of the 48 patients that underwent a two-stage procedure required a re-do urethroplasty within 3 years. Of the 31 patients who underwent a one-stage repair, six (19%) needed fistula closure, all of which were successful. No patient required a further urethroplasty during follow-up. CONCLUSIONS Despite the significant surgical challenges found in this patient group, excellent long-term functional outcomes can be achieved. As expected there is a need for additional intervention, either for revision of the first stage or to close fistulae and less commonly for further reconstruction for stricture recurrence.

Abstract
The acontractile bladder (AcB) is a urodynamic-based diagnosis wherein the bladder is unable to demonstrate any contraction during a pressure flow study. Although it is often grouped with underactive bladder, it is a unique phenomenon and should be investigated independently. The purpose of the present review was to examine the current literature on AcB regarding its pathology, diagnosis, current management guidelines, and future developments. We performed a review of the PubMed database, classifying the evidence for AcB pathology, diagnosis, treatment, and potential future treatments. Over the 67 years covered in our review period, 42 studies were identified that met our criteria. Studies were largely poor quality and mainly consisted of retrospective review or animal models. The underlying pathology of AcB is variable with both neurological and myogenic aetiologies. Treatment is largely tailored for renal preservation and reduction of infection. Although future developments may allow more functional restorative treatments, current treatments mainly focus on bladder drainage. AcB is a unique and understudied bladder phenomenon. Treatment is largely based on symptoms and presentation. While cellular therapy and neuromodulation may hold promise, further research is needed into the underlying neuro-urological pathophysiology of this disease so that we may better develop future treatments.

Abstract
BACKGROUND We aimed to determine UK medical students' perceptions and attitudes and interest toward medical leadership and clinician managers. METHODS A cross-sectional study was conducted during the academic year 2015-2016. An online questionnaire was distributed to 2,349 final-year students from 10 UK medical schools. Participants were asked to complete a 5-point Likert scale on their current perceptions, attitudes, and interest toward medical leadership and clinician managers. They were also asked to self-rate their leadership competences set by the Medical Leadership Competency Framework and to rate the quality of management and leadership training they received from their medical school. RESULTS In total, we received 114 complete responses. Only 7.9% of respondents were in agreement (strongly agree or agree) when asked whether they felt they were well informed about what a managerial position in medicine entails. When asked whether clinicians should influence managerial decisions within a clinical setting, 94.7% of respondents were in agreement with the statement. About 85% of respondents were in agreement that it is important for clinicians to have managerial or leadership responsibilities, with 63.2% of students in agreement that they would have liked more management or leadership training during medical school. Over half the respondents rated their management and leadership training they received during medical school as "very poor" or "poor" (54.4%). CONCLUSION Our study suggests that UK medical students have an appetite for management and leadership training and appreciate its importance but feel that the training they are receiving is poor. This suggests that there is a gap between the demand for management and leadership training and the quality of training supplied by UK medical schools.

Abstract
Synthetic or biological materials can be used for the surgical repair of pelvic organ prolapse (POP) or stress urinary incontinence (SUI). While non-degradable synthetic mesh has a low failure rate, it is prone to complications such as infection and erosion, particularly in the urological/gynecological setting when subject to chronic influences of gravity and intermittent, repetitive strain. Biological materials have lower complication rates, although allografts and xenografts have a high risk of failure and the theoretical risk of infection. Autografts are used successfully for the treatment of SUI and are not associated with erosion; however, can lead to morbidity at the donor site. Tissue engineering has thus become the focus of interest in recent years as researchers seek an ideal tissue remodeling material for urogynecological repair. Herein, we review the directions of current and future research in this exciting field. Electrospun poly-L-lactic acid (PLA) and porcine small intestine submucosa (SIS) are two promising scaffold material candidates. Adipose-derived stem cells (ADSCs) appear to be a suitable cell type for scaffold seeding, and cells grown on scaffolds when subjected to repetitive biaxial strain show more appropriate biomechanical properties for clinical implantation. After implantation, an appropriate level of acute inflammation is important to precipitate moderate fibrosis and encourage tissue strength. New research directions include the use of bioactive materials containing compounds that may help facilitate integration of the new tissue. More research with longer follow-up is needed to ascertain the most successful and safe methods and materials for pelvic organ repair and SUI treatment.

Abstract
CONTEXT Urogenital fistula is a global healthcare problem, predominantly associated with obstetric complications in low-resourced countries and iatrogenic injury in well-resourced countries. Currently, the published evidence is of relatively low quality, mainly consisting retrospective case series. OBJECTIVE We evaluated the available evidence for aetiology, intervention, and outcomes of urogenital fistulae worldwide. EVIDENCE ACQUISITION We performed a systematic review of the PubMed and Scopus databases, classifying the evidence for fistula aetiology, repair techniques, and outcomes of surgery. Comparisons were made between fistulae treated in well-resourced countries and those in low-resourced countries. EVIDENCE SYNTHESIS Over a 35-yr period, 49 articles were identified using our search criteria, which were included in the qualitative analysis. In well-resourced countries, 1710/2055 (83.2%) of fistulae occurred following surgery, whereas in low-resourced countries, 9902/10398 (95.2%) were associated with childbirth. Spontaneous closure can occur in up to 15% of cases using catheter drainage and conservative approaches are more likely to be successful for nonradiotherapy fistulae. Of patients undergoing repairs in well-resourced countries, the median overall closure rate was 94.6%, while in low-resourced countries, this was 87.0%. Closure was significantly more likely to be achieved using a transvaginal approach then a transabdominal technique (90.8% success vs 83.9%, Fisher's exact test; p=0.0176). CONCLUSIONS It is difficult to conclude whether any specific route of surgery has advantage over any other, given the selection of patients to a particular procedure is based upon individual fistula characteristics. However, surgical repair should be carried out by experienced fistula surgeons, well versed in all techniques as the primary attempt at repair is likely to be the most successful. PATIENT SUMMARY Urogenital fistulae are a common problem worldwide; however, the available evidence on fistula management is poor in quality. We searched the current literature and identified that 95% of fistulae occur following childbirth in low-resourced countries, whereas 80% of fistulae are associated with surgery in well-resourced countries, where successful repair is also more likely to be achieved. The first attempt at repair is often the most successful and therefore fistula surgery should be centralised to hospitals with the most experience.

Abstract
CONTEXT Stress urinary incontinence (SUI) is a common and bothersome problem that frequently requires operative management. Over the past two decades, novel techniques have been introduced into clinical practice. With the greater variety of surgical options now available, there is an increasing focus on selecting the appropriate procedure for the individual patient based on the likely underlying pathophysiologic mechanism. OBJECTIVE To review the methods used in the evaluation of SUI and the proposed classification systems. EVIDENCE ACQUISITION A search of the PubMed database for the relevant search terms was conducted, and selected articles were retrieved and reviewed. EVIDENCE SYNTHESIS Standardised terminology for the description of SUI has been produced by the International Continence Society describing the problem in terms of symptoms, clinical signs, and urodynamic observations. The two major pathophysiologic theories that have emerged over the past 50 yr, urethral hypermobility and intrinsic sphincteric deficiency, have influenced the development and adoption of surgical techniques. It is now recognised that these two entities are not dichotomous but often coexist. The primary aim of the evaluation of the patient presenting with SUI is to confirm the diagnosis and assess symptom severity before instituting conservative treatments. Secondary evaluation consists of more sophisticated techniques that assess anatomy of the bladder neck and urethra under rest and stress (eg, videourodynamics, ultrasound) or direct or indirect physiologic measures of the integrity of the sphincter mechanism. CONCLUSIONS Classification of patients with SUI into distinct groups based on probable pathophysiologic mechanism could help guide the choice of surgical procedure, but current systems are likely too simplistic, and methods of assessment lack standardisation in techniques and sensitivity. PATIENT SUMMARY Urinary leakage on exertion, termed stress incontinence, is a common problem that affects many women. There is a need to develop better ways of categorising the underlying causes of leakage to ensure that patients receive the optimal treatments.

Abstract
Detrusor underactivity (DU) is an important contributor to lower urinary tract symptoms (LUTS). While DU has been defined in the literature in urodynamic terms, current definitions lack specific parameters. In addition, the clinical syndrome associated with and manifesting itself as DU, underactive bladder (UAB), has not been well defined in the literature. In the absence of a precise definition of UAB, it is difficult to appreciate the true nature and burden of this condition. We review the evidence regarding the epidemiology, pathogenesis, diagnosis, and treatment of DU and UAB and discuss the challenges in gathering data in the absence of precise definitions. DU may be idiopathic or caused by ageing, medications, or a number of causes of neurogenic, myogenic, or iatrogenic origin. Treatments are largely palliative due to a lack of curative options, and include watchful waiting, catheterization, medications, and surgical interventions. In light of the evidence available in the literature, we propose that a new symptom-based definition of UAB syndrome should be developed as a first step in furthering more standardized research. Further discussion on this proposed definition to reach expert consensus will enable researchers to gather more robust data, allowing greater insights into DU and UAB diagnosis and treatment.

Abstract
Pelvic fracture urethral injuries comprise one of the most challenging reconstructive procedures in urology. The obliterated or stenosed urethra can usually be effectively repaired by an end-to-end anastomosis (bulbomembranous anastomosis). To achieve this, a progression of surgical steps can be used to make a tension-free anastomosis. Before undertaking surgery it is important to comprehensively assess the patient to define their anatomical defects, in particular the site of the stenosis, the length of the distraction injury and the integrity of the bladder neck, and thus guide preoperative decision-making. Contemporary reports suggest that most pelvic fracture urethral distraction defects (PFUDD) can be adequately managed by a perineal approach. Nevertheless it is essential that all surgeons treating these injuries are familiar with the whole spectrum of operative steps that are necessary to repair PFUDD.

Abstract
BACKGROUND Urethral strictures can be difficult to diagnose at an early stage because the urinary flow rate does not diminish until the urethral calibre is ≤3mm. In the past, posturethral surgery follow-up has relied upon flow rates and contrast imaging. OBJECTIVE To evaluate the role of flexible urethroscopy in the follow-up of patients undergoing urethroplasty. DESIGN, SETTING, AND PARTICIPANTS Prospective flexible urethroscopy follow-up of 144 male patients who underwent urethroplasty by a single surgeon over a 10-yr period at a tertiary referral centre. INTERVENTION Flexible urethroscopy at 3, 6, and 12 mo postoperatively, and annually thereafter. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Type of recurrence, based on urethroscopy findings, and further interventions were measured. Actuarial analysis was performed using Kaplan-Meier curves and a log-rank test. RESULTS AND LIMITATIONS All 144 patients underwent flexible urethroscopy follow-up over a median postoperative follow-up of 22 mo (range: 1-96 mo). No further intervention was required for 117 patients (81.25%); 27 (18.75%) developed recurrences that required further treatment. Recurrences included diaphragms (13 patients) or significant restenosis (14 patients). Diaphragms were treated by urethrotomy, gentle dilatation, or a short course of intermittent self-dilatation. Restenosis required repeated simple procedures or surgical revision. Most recurrences (26 of 27, 96%) were detected within the first year. Urinary peak flow-rate data were available for 11 of 27 of these recurrences; 7 patients had flow rates >15ml/s. Anastomotic procedures had greater success than augmentation urethroplasty (p=0.0136); there was no significant difference in outcomes between redo and non-redo surgery (p=0.2093) CONCLUSIONS: Endoscopic follow-up of patients after urethroplasty enables earlier identification and treatment of recurrences compared to the use of urinary flow rates alone. It also enables the identification of two different morphologic recurrence patterns that require different types of intervention. PATIENT SUMMARY Endoscopy detects most stricture recurrences within 1 yr after urethroplasty and is more sensitive than using urinary flow rates alone.

Abstract
Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) are major health issues that detrimentally impact the quality of life of millions of women worldwide. Surgical repair is an effective and durable treatment for both conditions. Over the past two decades there has been a trend to enforce or reinforce repairs with synthetic and biological materials. The determinants of surgical outcome are many, encompassing the physical and mechanical properties of the material used, and individual immune responses, as well surgical and constitutional factors. Of the current biomaterials in use none represents an ideal. Biomaterials that induce limited inflammatory response followed by constructive remodelling appear to have more long term success than biomaterials that induce chronic inflammation, fibrosis and encapsulation. In this review we draw upon published animal and human studies to characterize the changes biomaterials undergo after implantation and the typical host responses, placing these in the context of clinical outcomes.

Abstract
PURPOSE Autologous buccal mucosa is commonly utilized in the surgical treatment of urethral strictures. Extensive strictures require a larger quantity of tissue, which may lead to donor site morbidity. This review assesses progress in producing tissue engineered buccal mucosa as an alternative graft material. RESULTS Few clinical studies have introduced cells onto biological or synthetic scaffolds and implanted resulting constructs in patients. The available studies show that buccal mucosa cells on acellular human dermis or on collagen matrix lead to good acute stage tissue integration. Urothelial cells on a synthetic substrate also perform well. However while some patients do well many years post-grafting, others develop stricture recurrence. Acellular biomaterials used to treat long urethral defects in animals commonly lead to fibrosis. CONCLUSIONS Tissue engineered buccal mucosa shows promise as a substitute for native tissue. The fibrosis which occurs months post-implantation may reflect the underlying disease process recurring in these patients.

Abstract
Detrusor underactivity (DUA) is a poorly understood, yet common, bladder dysfunction, referred to as underactive bladder, which is observed in both men and women undergoing urodynamic studies. Despite its prevalence, no effective therapeutic approaches exist for DUA. Exactly how the contractile function of the detrusor muscle changes with ageing is unclear. Data from physiological studies in animal and human bladders are contradictory, as are the results of the limited number of clinical studies assessing changes in urodynamic parameters with ageing. The prevalence of DUA in different patient groups suggests that multiple aetiologies are involved in DUA pathogenesis. Traditional concepts focused on either efferent innervation or myogenic dysfunction. By contrast, contemporary views emphasize the importance of the neural control mechanisms, particularly the afferent system, which can fail to potentiate detrusor contraction, leading to premature termination of the voiding reflex. In conclusion, the contemporary understanding of the aetiology and pathophysiology of DUA is limited. Further elucidation of the underlying mechanisms is needed to enable the development of new and effective treatment approaches.

Abstract
Synthetic non-degradable meshes used in pelvic floor surgery can cause serious complications such as tissue erosion. A repair material composed of an autologous oral fibroblast seeded degradable polylactic acid scaffold may be a viable alternative. The aims of this study were to investigate the effects of media supplementation with additives (ascorbic acid-2-phosphate, glycolic acid and 17-β-oestradiol) on the mechanical properties of these scaffolds. Oral fibroblasts were isolated from buccal mucosa. The effects of the three additives were initially compared in two-dimensional culture to select the most promising collagen stimulating additive. Sterile electrospun scaffolds were seeded with 500,000 oral fibroblasts and fixed in 6-well plates and subjected to ascorbic acid-2-phosphate (the best performing additive) and/or mechanical stimulation. Mechanical stimulation by fluid shear stress was induced by rocking scaffolds on a platform shaker for 1 h/day for 10 of 14 days of culture. In two-dimensional culture, ascorbic acid-2-phosphate (concentrations from 0.02 mM to 0.04 M) and glycolic acid (10 µM) led to significantly greater total collagen production, but ascorbic acid-2-phosphate at 0.03 mM produced the greatest stimulation (of the order of >100%). In three-dimensional culture, mechanical stimulation alone gave non-significant increases in stiffness and strength. Ascorbic acid-2-phosphate (0.03 mM) significantly increased collagen production in the order 280% in both static and mechanically stimulated scaffolds (p < 0.0001). There was no additional effect of mechanical stimulation. Dense collagen I fibres were observed with ascorbic acid-2-phosphate supplementation. Uniaxial tensiometry showed that strength (p < 0.01) and stiffness (p <0.05) both improved significantly. A combination of ascorbic acid-2-phosphate and mechanical stimulation led to further non-signficant increases in strength and stiffness. In conclusion, a pelvic floor repair material with improved mechanical properties can be developed by supplementing culture media with ascorbic acid-2-phosphate to increase collagen I production. Future studies will assess the change in mechanical properties after implantation in an animal model.

Abstract
The assessment of men with bladder outflow obstruction relies on an adequate history and examination. Uroflowmetry and post-void residue estimation are very revealing and may be sufficient in the majority of men. The prostate-specific antigen test may be used to select men who are at a high risk of progression. In specific situations, cystometry may be required. We discuss the use of cystometry and the newer less-invasive methods of assessment that have emerged over the last few years, including ultrasound estimation of intravesical prostatic protrusion, prostatic urethra angle, detrusor wall thickness, ultrasound-estimated bladder weight, near-infrared spectroscopy and the condom catheter and penile cuff tests. Although these techniques show promise, they still require further modifications, standardization and testing in larger populations. In addition, they should be used in men where only specific questions need to be answered.
