RESUMO
PURPOSE: To synthetize the current scientific knowledge on the use of ultrasound of the male urethra for evaluation of urethral stricture disease. This review aims to provide a detailed description of the technical aspects of ultrasonography, and provides some indications on clinical applications of it, based on the evidence available from the selected prospective studies. Advantages and limitations of the technique are also provided. METHODS: A comprehensive literature search was performed using the Medline and Cochrane databases on October 2022. The articles were searched using the keywords "sonourethrography", "urethral ultrasound", "urethral stricture" and "SUG". Only human studies and articles in English were included. Articles were screened by two reviewers (M.F. and K.M.). RESULTS: Our literature search reporting on the role of sonourethrography in evaluating urethral strictures resulted in selection of 17 studies, all prospective, even if of limited quality due to the small patients' number (varied from 28 to 113). Nine studies included patients with urethral stricture located in anterior urethra and eight studies included patients regardless of the stricture location. Final analysis was based on selected prospective studies, whose power was limited by the small patients' groups. CONCLUSION: Sonourethrography is a cost-effective and safe technique allowing for a dynamic and three-dimensional urethra assessment. Yet, because of its limited value in detecting posterior urethral strictures, the standard urethrography should remain the basic 'road-map' prior to surgery. It is an operator-dependent technique, which can provide detailed information on the length, location, and extent of spongiofibrosis without risks of exposure to ionizing radiation.

PURPOSE: This study directly compares peri-catheter retrograde urethrography (pcRUG) and voiding cysto-urethrography (VCUG) as early postoperative imaging after urethroplasty and aims to assess whether pcRUG is superior at avoiding catheter reinsertion. METHODS: This is a single-center, prospective, interventional study comparing pcRUG and VCUG after urethroplasty in a within-patient fashion. All participants were first evaluated with pcRUG and subsequently with VCUG, unless pcRUG revealed significant contrast extravasation warranting further catheter stay. The primary end-point was to assess whether pcRUG is superior at avoiding catheter reinsertion compared with VCUG. Secondary end-points included the amount of significant contrast extravasations missed on pcRUG and the differences in radiation exposure. RESULTS: 80 patients were included in this study. Median (IQR) interval between surgery and first postoperative imaging was 16 (9-16) days. In 14/80 (18%) patients, the pcRUG showed significant contrast extravasation and catheter reinsertion was avoided, while this percentage is 0 by default for VCUG (p < 0.001). In the other 66/80 (82%) patients, a VCUG was performed and 1/66 (1.5%) of these was considered as significant contrast extravasation. Notably, 9/66 (14%) of these patients could not void during the investigation. Median (IQR) dose of radiation exposure during pcRUG and VCUG was, respectively, 120 (84-161) mGy/cm2 and 241 (169-334) mGy/cm2 (p < 0.001). CONCLUSIONS: After urethroplasty, pcRUG is a valuable alternative for VCUG as early postoperative imaging. It has a comparable diagnostic yield, averts the risk of having to reinsert the catheter, avoids the problem of patients being unable to void during the examination and requires significantly less radiation.

PURPOSE: The benefits and harms of the available types of surgical management for lichen sclerosus-related (LS) strictures remain unclear and, thus, clear and robust clinical practice recommendations cannot be given. MATERIALS AND METHODS: To assess the role of single-stage OMGU in the management of LS strictures and explore how its benefits and harms compare with the alternative management options. Medline, Embase and Cochrane controlled trial databases (CENTRAL, CDSR) were systematically searched. Randomized (RCTs) and nonrandomized studies (NRCSs) comparing single-stage OMGU with other surgical management options for LS strictures and single-arm studies on single-stage OMGU were included. Risk of bias (RoB) was assessed. RESULTS: Of the 1912 abstracts identified, 15 studies (1 NRCS and 14 single-arm studies) were included, recruiting in total 649 patients. All studies were at high RoB. In the only NRCS available, stricture-free rate (SFR) for single-stage and staged OMGU was 88% vs 60%, respectively (p = 0.05), at a mean follow-up of 66.5 months. SFR range for single-stage OMGU in single-arm studies was 65-100% (mean/median follow-up, 12-59 months). Single-stage OMGU had low complication rates and beneficial impact on LUTS and QoL. CONCLUSIONS: The present SR highlights the methodological limitations of the available literature. In the absence of adverse local tissue conditions, and taking into consideration benefit-harm balance and surgeon's skills and expertise, single-stage OMGU can be justified in patients with LS strictures.

BACKGROUND: Until recently, all available erectile devices were manufactured in accordance with the anatomy of a native penis and led to high explantation rates when implanted in the neophallus. AIM: The aim of this study was to investigate surgical outcomes after implantation of the ZSI 475 FTM in the neophallus; this is the first erectile device specifically manufactured for implantation after phalloplasty. METHODS: This is a prospective observational study of patients undergoing implantation of the ZSI 475 FTM in the neophallus at a tertiary referral center since September 2017. Patients with a follow-up < 3 months were excluded from this analysis. OUTCOMES: Intraoperative and postoperative complications were analyzed with descriptive statistics and explantation-free survival was assessed using a Kaplan-Meier survival analysis. RESULTS: In total, 57 patients were included with a median (IQR) follow-up of 16 (10-21) months. No intraoperative complications occurred. Postoperative complications were seen in 18 of 57 (32%) patients and included cylinder protrusion (1/57, 1.8%), infection (8/57, 14%), malpositioning (4/57, 7.0%), mechanical failure (4/57, 7.0%), and urinary retention (1/57, 1.8%). A total of 13 of 57 (23%) devices were explanted which corresponds with an estimated explantation-free survival rate (SD) of 84% (4.9), 80% (5.6), and 80% (5.6) after, respectively, 6, 12, and 18 months of follow-up. CLINICAL IMPLICATIONS: By better addressing the specific needs after phalloplasty, this innovative erectile device might lead to improved cylinder protrusion, malpositioning, and mechanical failure rates, but device infection remains common. STRENGTHS & LIMITATIONS: This is the largest study on this topic to date and the first to report prospective data. Main limitations involve the relatively small sample size and the limited follow-up. CONCLUSION: Short-term cylinder protrusion, malpositioning, and mechanical failure rates are encouraging, although device infection remains a common problem. These complications resulted in a device explantation rate of 23%. Verla W, Goedertier W, Lumen N, et al.

BACKGROUND: Possible options of genital gender affirming surgery in transmasculine are metoidioplasty or phalloplasty. As opposed to phalloplasty, no flapbased neophallic reconstruction is needed in metoidioplasty. Urethral lengthening is needed in metoidioplasty if the patient desires voiding at the tip of the neophallus. This urethral lengthening poses the patient at risk for urethral complications. AIM: Our primary goal was to describe the morbidity and specific the urethral complications related to metoidioplasty. Second, we sought for predictors of these urethral complications. METHODS: Our institutional database was retrospectively analyzed to identify transmasculine who underwent metoidioplasty between 2006 and 2020. This cohort was further evaluated for surgical morbidity, urethral complications and potential predictors for urethral complications. OUTCOMES: The rate of surgical morbidity and urethral complications (temporary/permanent fistula, stricture or fistula and stricture) was calculated. Potential predictors evaluated herein were BMI, concomitant vaginectomy, active smoking and additional urethral lengthening (AUL). They were tested with logistic regression analysis with calculation of Odds Ratio (OR). RESULTS: Seventy-four patients underwent metoidioplasty with a median follow-up of 44 months. Median age was 26 years. AUL was done in 36 (48.6%) patients and established by a transverse preputial skin island and labium minus flap in respectively 34 and 2 patients. Within 30 days after metoidioplasty, 3 (4.1%) high-grade complications were noted. Urethral complications of any kind were noted in 42 (56.8%) patients. All fistulas, permanent fistulas and strictures were seen in resp. 34 (45.9%), 27 (36.5%) and 14 (18.9%) patients. AUL is a significant predictor for all urethral complications (OR 15.5), strictures (OR 24.5), all fistula's (OR 6.07) and permanent fistulas (OR 3.83). In contrast, smoking is only a predictor for all fistulas (OR 6.54) and permanent fistulas (OR 3.76). CLINICAL IMPLICATIONS: Obtaining information about the risk of complications is important in preoperative patient counselling. Patient who desires AUL are at higher risk to develop urethral complications and patients who continue to smoke at the period of metoidioplasty have a higher risk of fistula formation. STRENGTH & LIMITATIONS: Sufficient events to calculate predictors for urethral complications. However, this is a retrospective study with still a small number of patients with a relative short follow-up. CONCLUSION: Urethral complications are frequent after metoidioplasty and approximately 50% needs corrective surgery. AUL is an independent risk factor for fistula and stricture formation, whereas smoking is a risk factor for fistula formation. Waterschoot M, Hoebeke P, Verla W, et al.

PURPOSE OF REVIEW: This narrative review summarizes the most relevant literature published in 2019-2020 regarding urethroplasty for bulbar strictures. RECENT FINDINGS: We identified relevant papers focussing on new insights in the field of excision and primary anastomosis, graft augmentation urethroplasty and perineostomy for bulbar strictures and bulbomembranous strictures after radiotherapy or surgery for benign prostatic hyperplasia. SUMMARY: Respecting the vascularity of the anterior urethra and maintaining the integrity of surrounding structures during bulbar urethroplasty does not appear to deteriorate surgical outcomes and might be associated with improved functional outcomes.

PURPOSE: To identify independent risk factors for urethroplasty failure in a prospective dataset. METHODS: Since 2008, data of all male patients undergoing urethroplasty at Ghent University Hospital have been prospectively recorded and maintained. This analysis excluded: posterior strictures, strictures of the perineostomy, urethral malignancy-related strictures, age < 18 years and follow-up < 1 year. Postoperatively, a voiding cysto-urethrography (VCUG) was performed after 2 weeks and in absence of significant contrast extravasation, the transurethral catheter was removed. Patients were followed after 3 m, 12 m and annually thereafter. Failure was defined as stricture recurrence requiring additional urethral intervention(s). Uni- and multivariate Cox regression analyses were performed on the entire patient cohort and for one-stage urethroplasty (OSU) at specific locations. RESULTS: In total, 474 patients were included. Median follow-up was 62 m (IQR 35-91). Significant extravasation was present in 6.9%. Bulbar stricture location was identified as independent protective factor for urethroplasty failure (HR 0.44; p = 0.046) and significant extravasation at first VCUG was identified as independent risk factor for urethroplasty failure (HR 2.86; p = 0.005). Cox regression analyses for OSU at specific locations could not identify other risk factors. All but one (89%) of the failures preceded by significant extravasation at first VCUG occurred within 2 years of follow-up whereas 44% of the failures with no or insignificant extravasation at first VCUG occurred after 2 years of follow-up (p = 0.03). CONCLUSIONS: Bulbar stricture location is an independent protective factor for urethroplasty failure. Significant extravasation at first urethrography is an independent risk factor for urethroplasty failure and is associated with earlier stricture recurrence than other failed cases.

The present study assessed the efficacy of hyperbaric oxygen therapy in reducing symptoms of radiation cystitis, a specific type of iatrogenic injury to the bladder, by systematic review of recent literature. The MEDLINE, Embase and Web of Science databases were searched using combinations of the terms "radiation," "cystitis" and "hyperbaric oxygen" to identify articles evaluating patients with radiation cystitis, treated with hyperbaric oxygen therapy. Only recent (≤10 years) original studies were included. Data were extracted and pooled in order to calculate descriptive weighted averages. Articles were evaluated on their level of evidence. A total of 20 papers were obtained, resulting in a cohort of 815 patients who were treated with hyperbaric oxygen therapy for radiation cystitis. Overall and complete response rates varied from 64.8% to 100% and 20% to 100%, respectively. The weighted average overall and complete response rates were 87.3% and 65.3%, respectively. Adverse events were observed in 9.6% of the patients, but permanent side-effects were rare. The most prominent limitations were high cost and low availability. Hyperbaric oxygen therapy is effective in the treatment of radiation-induced cystitis, with minimal adverse events, but low availability and high cost. At present, evidence is low; therefore, more prospective studies are required.

PURPOSE: The study aimed to translate the Urethral Stricture Surgery Patient Reported Outcome Measures (USS-PROM) questionnaire in Dutch. To validate this translated questionnaire, the study evaluates its psychometric properties in a different population, a different environment, and a different health care system. Questions about urinary incontinence and sexual functioning were added. MATERIALS AND METHODS: Between December 2014 and January 2017, Dutch-speaking adult men scheduled for urethroplasty at Ghent University Hospital were prospectively enrolled in this study. Patients completed the USS-PROM before surgery, 3-6 months after surgery, and 1 year after surgery. Psychometric criteria included content validity, criterion validity, internal consistency, reproducibility, responsiveness, and floor and ceiling effects. (EC/2014/0438). RESULTS: A total of 100 patients were included, 39 patients completed both the preoperative and the postoperative questionnaire, and 30 patients completed the USS-PROM twice within a short period of time in order to evaluate test-retest reliability. Pearson correlation coefficients showed no statistical significant correlation between lower urinary tract symptoms (LUTS) scores and maximum flow rates. Cronbach's α was 0.81 and 0.89, respectively, for the LUTS score and the summative Male Sexual Health Questionnaire Ejaculatory Dysfunction short form (MSHQ-EjD short form) score. The intraclass correlation coefficients ranged from 0.72 to 0.94. Significant changes were observed in all items except the MSHQ-EjD short form scores. All values exceeded the predefined thresholds. CONCLUSIONS: The Dutch version of the USS-PROM has adequate psychometric properties and is a valid instrument to assess patient-reported outcome measures in men undergoing urethroplasty.

CONTEXT: The European Association of Urology (EAU) Guidelines Panel for Urological Trauma has produced guidelines in order to assist medical professionals in the management of urological trauma in adults for the past 20 yr. It must be emphasised that clinical guidelines present the best evidence available to the experts, but following guideline recommendations will not necessarily result in the best outcome. Guidelines can never replace clinical expertise when making treatment decisions for individual patients regarding other parameters such as experience and available facilities. Guidelines are not mandates and do not purport to be a legal standard of care. OBJECTIVE: To present a summary of the 2023 version of the EAU guidelines on the management of urological trauma. EVIDENCE ACQUISITION: A systematic literature search was conducted from 1966 to 2022, and articles with the highest certainty evidence were selected. It is important to note that due to its nature, genitourinary trauma literature still relies heavily on expert opinion and retrospective series. EVIDENCE SYNTHESIS: Databases searched included Medline, EMBASE, and the Cochrane Libraries, covering a time frame between May 1, 2021 and April 29, 2022. A total of 1236 unique records were identified, retrieved, and screened for relevance. CONCLUSIONS: The guidelines provide an evidence-based approach for the management of urological trauma. PATIENT SUMMARY: Trauma is a serious public health problem with significant social and economic costs. Urological trauma is common; traffic accidents, falls, intrapersonal violence, and iatrogenic injuries are the main causes. Developments in technology, continuous training of medical professionals, and improved care of polytrauma patients reduce morbidity and maximise the opportunity for quick recovery.
RESUMO
Introduction: The artificial urethral sphincter (AUS) is the gold standard treatment in cases of moderate-to-severe stress urinary incontinence in males. Cuff erosions are one of the most important distant complications of AUS implantation. The optimal urethral management has still not been established. Material and methods: Search terms related to 'urethral stricture', 'artificial urinary sphincter', and 'cuff erosion' were used in the PubMed database to identify relevant articles. Results: In this mini review we identified 6 original articles that assessed the urethral management after AUS explantation due to cuff erosion and included urinary diversion by transurethral and/or suprapubic catheterization, urethrorrhaphy, and in situ urethroplasty. We summarized the results of different management methods and their efficacy in terms of preventing urethral stricture formation. We highlight the need for better-quality evidence on this topic. Conclusions: The available data do not provide a clear answer to the question of optimal urethral management during AUS explantation. There is a great need to provide higher-quality evidence on this topic.
RESUMO
Context: Intermittent self-dilatation (ISD) is a therapeutic strategy used to stabilise a urethral stricture and postpone or avoid further treatment. Adding corticosteroids to this mode of management might further enhance its outcomes by downregulation of collagen deposition and excessive scar tissue formation. Objective: To explore whether a course of ISD with topical corticosteroids is superior at stabilising urethral stricture disease in men and improving functional outcomes over a course of ISD alone. Evidence acquisition: This systematic review and meta-analysis was undertaken by the European Association of Urology Urethral Strictures Guideline Panel according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines (CRD42021256744). The primary benefit outcome was successful stabilisation of the urethral stricture. Treatment-related complications were the primary harm outcome. Evidence synthesis: In total, 978 records were screened for eligibility, ultimately leading to five included studies, all randomised controlled trials, comprising 250 patients, of whom 124 underwent a course of ISD with corticosteroids and 126 underwent a course of ISD alone, all after direct vision internal urethrotomy (DVIU). Successful stabilisation of the stricture was achieved in 77% and 64% of patients in the group with and without corticosteroids, respectively (pâ¯=â¯0.04). No extra complications related to the addition of corticosteroids to the ISD regimen were reported. The risk of bias of the included studies was generally unclear to high. Conclusions: Based on the currently available data, a course of ISD with topical corticosteroids appears to be safe and superior at stabilising a urethral stricture after DVIU in the short term to a course of ISD alone. However, given the unclear to high risk of bias in the included studies, further high-quality studies are needed to fully underpin this. Patient summary: This study shows that addition of topical corticosteroids to intermittent self-dilatation after direct vision internal urethrotomy can better stabilise the stricture in the short term.
RESUMO
Urethral stricture disease is a very heterogeneous condition where different urethral segments can be involved as a result of diverse etiologies which come with variable prognosis. The surgical management of urethral strictures, and in particular urethroplasties can result in very diverse outcomes on many levels and, currently, there is absolutely no consensus about what should and what should not be considered a "success" after urethral surgery. In the wake of well-established quality criteria in urologic oncology, such as tri- or pentafecta outcomes, and given the lack of agreement on meaningful outcomes after urethral surgery, we aim to introduce our study protocol as the first step of a multistep research endeavor to reach consensus on comprehensive urethroplasty outcomes within a novel conceptual framework: the "stricture-fecta criteria". The development of stricture-fecta will be based on a Delphi consensus involving some of worldwide most influencing reconstructive urologists.
RESUMO
Assessment of anterior urethral stricture (US) management of European urology experts is relevant to evaluate the quality of care given to the patients and plan future educational interventions. We assessed the practice patterns of the management of adult male anterior US among reconstructive urology experts from European countries. A 23-question online survey was conducted among European Association of Urology Section of Genito-Urinary Reconstructive Surgeons (ESGURS) members. A total of 88 invitations were sent by email at two different times (May and October 2019). Data were prospectively collected from May 2019 to December 2019. The response rate was 55.6%. Most of the responders were between 50 and 59 y.o. and mainly from University Public Teaching/Academic Hospitals. A total of 73.5% treated ≥20 patients/year with US. Retrograde urethrogram (RUG) was the commonest diagnostic tool, followed by uroflowmetry (UF) +/− post-void residual (PVR). Urethroplasty using grafts was the most frequent treatment (91.8%). Of responders, 55.3% performed >20 urethroplasties/year. Anastomotic urethroplasties were performed by 83.7%, skin flap repairs by 61.2%, perineal urethrostomy by 77.6% and non-transecting techniques by 63.3%. UF was the most common follow-up tool. Most of the responders considered urethroplasty as the primary option when indicated. Male anterior US among ESGURS members are treated mainly using urethroplasty graft procedures. RUG is preferred for diagnosis, and UF for follow-up.
RESUMO
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.

Radiotherapy is a frequently used treatment for prostate cancer. It does not only causes the intended damage to cancer cells, but also affects healthy surrounding tissue. As a result radiation-induced urethral strictures occur in 2.2% of prostate cancer patients. Management of urethral strictures is challenging due to the presence of poor vascularized tissue for reconstruction and the proximity of the sphincter, which can impair the functional outcome. This review provides a literature overview of risk factors, diagnostics and management of radiation-induced urethral strictures.
RESUMO
INTRODUCTION: Female urethral strictures and injuries are relatively uncommon compared to males. A wide range of possible causes and treatment modalities have been described. Lately female urethral reconstruction is gaining attention and is fortunately no longer a neglected topic within the reconstructive urology. As such, we aimed to describe our surgical techniques and outcomes for female urethroplasty from a tertiary center. MATERIALS AND METHODS: Records of female patients who underwent a urethroplasty between July 2018 and May 2021 in our tertiary referral center were reviewed. Patients were subdivided in two groups: patients who suffered from a urethral injury and received an early repair urethroplasty, and patients with a true urethral stricture who received a delayed urethroplasty. Preprocedural, surgical and postoperative data were collected and analyzed with descriptive statistics. RESULTS: A total of five patients in group 1 and nine patients in group 2 were included. Etiology of the urethral injury in group 1 was iatrogenic in 80% and transitional cell carcinoma of the urethra in 20% of cases. A patency rate of 100% at a follow-up of 30 months was achieved with the different techniques. In group 2 etiology was idiopathic (44%), iatrogenic (44%) and due to external trauma in 12% of cases. Urethroplasty technique consisted of primary repair or dorsal onlay of a buccal mucosal graft. Patency rate was 100% at a median follow-up of 13 months. Three patients suffered from postoperative urinary incontinence, one in group 1 and two in group 2. CONCLUSION: Female urethroplasty is a relatively rare entity within reconstructive urethral surgery. This case series of 14 patients demonstrates that with appropriate surgical techniques, a high patency rate with a low complication rate can be achieved. Further prospective studies with standardized diagnostic workup and follow-up should be performed in order to optimize management strategy.
RESUMO
BACKGROUND: To report on the use of oral mucosa graft urethroplasty for meatal strictures using the dorsal inlay technique. METHODS: Patients who underwent a single-stage dorsal inlay oral mucosal graft urethroplasty between January 2000 and May 2021 were included in this study. A follow-up of a minimum of 12 months was necessary for inclusion. Exclusion criteria were stricture extension into the penile urethra, concomitant stricture at another location, flap urethroplasty for a meatal stricture, dorsal inlay urethroplasty with another type of graft, ventral onlay graft urethroplasty or staged urethroplasty. Recurrence was defined by the inability to pass a 14F metal sound through the reconstructed meatus irrespective of patients' complaints. RESULTS: Our study cohort included 40 patients. Buccal mucosal graft (BMG) urethroplasty was used in 25 patients and 15 patients were treated with the aid of lingual mucosal graft (LMG). The median follow-up was 85 (IQR: 69-110) months. Seven (17.5%) patients suffered a stricture recurrence of which four (10%) needed re-intervention. The median 5-y recurrent free survival (RFS) for the entire cohort was 85 (±6)%. The median 5-y RFS was 96 (±4)% versus 65 (±13)% for respectively BMG and LMG (p = 0.03). Post-operative complications were identified in 11 (27.5%) patients with only one (2.5%) patient who had a grade 3a complication. CONCLUSIONS: Dorsal inlay oral mucosa graft urethroplasty is a safe and feasible technique for selected patients with meatal stenosis.
