Abstract
OBJECTIVE To evaluate patient-reported quality of life (PRQoL) in patients presenting with membranous urethral stenosis after prostate radiotherapy. Urethral stenosis is an under-reported complication after prostate radiotherapy with a particular deficiency in PRQoL. METHODS Patients presenting with urethral stenosis after radiotherapy were retrospectively reviewed from 2004 to 2022. PRQoL was assessed via patient survey using the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP). RESULTS Two hundred thirty patients were identified at a mean age of 67.7years and mean time to stricture diagnosis of 63.6months' postradiotherapy. Of 87 patients completing the survey, 29.9% recalled being aware of urethral stenosis as a potential complication and 51.7% had documentation of urethral stenosis as a potential complication. 33.5% of patients underwent urethroplasty, 59.6% repeat endoscopic treatment and 6.1% an indwelling catheter. 64.4% of patients reported urinary dysfunction as a "moderate" or "big" problem, 66.7% reported frequent or total incontinence, 64.4% required daily pad use and 50.6% reported incontinence as either a "moderate" or "big" problem. 85.0% reported poor or absent orgasmic dysfunction and 88.5% reported erections insufficient for sexual activity. Additionally, 47.1% of patients reported rectal pain and 31.0% reported dysuria. Depressive symptoms and fatigue were reported by 41.4% and 60.9% of patients respectively. CONCLUSION Urethral stenosis after radiotherapy is a clinically complex entity with a broad scope of associated symptoms including high rates of patient-reported incontinence, voiding dysfunction, sexual dysfunction, pain, bowel dysfunction and depression. This multifocal nature combined with often insidious presentation and patient unawareness creates a uniquely challenging condition to treat.

Barnard J, Liaw A, Gelman J. Long-term follow-up suggests high satisfaction rates for bulbomembranous radiation-induced urethral stenoses treated with anastomotic urethroplasty. World J Urol 2023; 41:1905-1912. [PMID: 37314572 PMCID: PMC10352169 DOI: 10.1007/s00345-023-04429-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 04/18/2023] [Indexed: 06/15/2023] Open
Abstract
PURPOSE To analyze patients who underwent anastomotic urethroplasty for radiationinduced bulbomembranous urethral stricture/stenosis (RIS) due to prostate cancer treatment with up to 19 years of follow-up and assess long-term patient reported outcomes (PROMs). Long-term follow-up with the inclusion of urethroplasty specific PROMs is lacking in the available research. METHODS Patients who underwent anastomotic urethroplasty for RIS were identified from 2002 to 2020. Inclusion criteria included completion of 4-month post-operative cystoscopy and PROMs including IPSS, SHIM, MSHQ-EF, 6Q-LUTS, and global satisfaction queries at 4 months. PROMs were assessed annually thereafter, and cystoscopy was performed for adverse change in PROMs or worsening uroflow/PVR parameters. PROMs were compared at pre-op, post-op, and most recent follow-up. RESULTS 23 patients met inclusion criteria. Short-term anatomic success was 95.7%. At a mean follow-up of 73.1 months (9.1-228.9), one late recurrence occurred for an overall success of 91.3%. Significant and sustained objective improvement was identified in voiding scores, quality of life, and urethroplasty specific PROMs. Satisfaction was 91.3% despite sexual side effects, and 95.7% of patients stated they would have surgery again knowing their outcome at a mean of over 6 years' follow up. CONCLUSIONS RIS are challenging problems, but durable symptomatic relief is achievable in well-selected patients. Patients with bulbomembranous RIS should be appropriately counseled regarding the risk of urinary incontinence and sexual side effects after anastomotic urethroplasty. However, long-term success is high, and overall QoL will have sustained subjective improvement in most cases.

Abstract
Radiation therapy (RT) in the management of pelvic cancers remains a clinical challenge to urologists given the sequelae of urethral stricture disease secondary to fibrosis and vascular insults. The objective of this review is to understand the physiology of radiation-induced stricture disease and to educate urologists in clinical practice regarding future prospective options clinicians have to deal with this condition. The management of post-radiation urethral stricture consists of conservative, endoscopic, and primary reconstructive options. Endoscopic approaches remain an option, but with limited long-term success. Despite concerns with graft take, reconstructive options such as urethroplasties in this population with buccal grafts have shown long-term success rates ranging from 70 to 100%. Robotic reconstruction is augmenting previous options with faster recovery times. Radiation-induced stricture disease is challenging with multiple interventions available, but with successful outcomes demonstrated in various cohorts including urethroplasties with buccal grafts and robotic reconstruction.

Abstract
Radiation is a common treatment modality for pelvic malignancies. While it can be effective at cancer control, downstream effects can manifest months to years after treatment, leaving patients with significant morbidity. Within urology, a particularly difficult post-radiation consequence is urinary tract stricture, either of the urethra, bladder neck, or ureter. In this review, we will discuss the mechanism of radiation damage and treatment options for these potentially devastating urinary sequelae.

A TriNetX Registry Analysis of the Need for Second Procedures following Index Anterior and Posterior Urethroplasty. J Clin Med 2023; 12:jcm12052055. [PMID: 36902842 PMCID: PMC10004265 DOI: 10.3390/jcm12052055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 02/28/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND We queried a global database to understand re-intervention rates following urethroplasty with the goal of evaluating whether they align with previously published data. METHODS Using the TriNetX database and Common Procedural Terminology (CPT) and International Classification of Diseases-10 (ICD) codes, we identified adult male patients with urethral stricture disease (ICD N35) who underwent one-stage anterior (CPT 53410) or posterior urethroplasty (CPT 53415), with or without (substitution urethroplasty) a tissue flap (CPT 15740) or buccal graft (CPT 15240 or 15241). We set urethroplasty as the index event and used descriptive statistics to report the incidence of secondary procedures (using CPT codes) within 10 years after the index event. RESULTS There were 6606 patients who underwent urethroplasty within the last 20 years, with 14.3% of patients undergoing a second procedure after index event. Upon subgroup analysis, reintervention rates were 14.5% for anterior urethroplasty vs. 12.4% of patients with an anterior substitution urethroplasty (RR 1.7, p = 0.09) and 13.3% for posterior urethroplasty vs. 8.2% for patients with a posterior substitution urethroplasty (RR 1.6, p < 0.01). CONCLUSIONS Most patients will not need any form of re-intervention following urethroplasty. These data align with previously described recurrence rates, which may help urologists counsel patients considering urethroplasty.

Multi-Institutional Study of Dorsal Onlay Urethroplasty of the Membranous Urethra after Endoscopic Prostate Procedures: Operative Results, Continence, Erectile Function and Patient Reported Outcomes. J Clin Med 2021; 10:jcm10173969. [PMID: 34501417 PMCID: PMC8432256 DOI: 10.3390/jcm10173969] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Revised: 08/22/2021] [Accepted: 08/23/2021] [Indexed: 11/16/2022] Open
Abstract
(1) Background: To critically evaluate dorsal onlay buccal mucosal graft urethroplasty (DOBMGU) for posterior urethral stenosis repair following transurethral resection and other endoscopic prostate procedures. (2) Methods: A retrospective multi-institutional review of patients with membranous or bulbomembranous urethral stenosis for whom treatment with DOBMGU was conducted after receipt of prostate endoscopic procedures. Baseline data, peri-operative care, post-operative care and patient-reported outcomes were analyzed. The primary outcomes were procedural failure and development of de novo stress urinary incontinence (SUI). The secondary outcomes were changes in voiding, sexual function and patient satisfaction. (3) Results: A total of 107 men with a mean age of 69 ± 9.5 years and stenosis length of 3.5 ± 1.8 cm were included. Prior endoscopic procedures among participants were 47 patients (44%) with monopolar TURP, 33 (30.8%) with bipolar TURP, 16 (15%) with Greenlight laser, 9 (8.4%) with Holmium laser enucleation and 2 (1.9%) with bladder neck incision. At a mean follow-up time of 59.3 ± 45.1 months, stenosis recurred in 10 patients (9.35%). Multivariate analysis confirmed that postoperative complications (OR 12.5; p = 0.009), history of radiation (OR 8.3; p = 0.016) and ≥2 dilatations before urethroplasty (OR 8.3; p = 0.032) were independent predictors of recurrence. Only one patient (0.9%) developed de novo SUI. Patients experienced significant improvement in PVR (128 to 60 cc; p = 0.001), Uroflow (6.2 to 16.8 cc/s; p = 0.001), SHIM (11.5 to 11.7; p = 0.028), IPSS (20 to 7.7; p < 0.001) and QoL (4.4 to 1.7; p < 0.001), and 87 cases (81.3%) reported a GRA of + 2 or better. (4) Conclusions: DOBMGU is an effective and safe option for patients with posterior urethral stenosis following TURP and other prostate endoscopic procedures. This non-transecting approach minimizes external urinary sphincter manipulation, thus limiting postoperative risk of SUI or erectile dysfunction.

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
Background: Robotic pelvic surgery is being increasingly utilized for reconstruction proximal to the genitourinary diaphragm. We describe a combined robotic, transabdominal, and open transperineal approach for complex anastomotic posterior urethroplasty. Materials and Methods: We performed a multi-institutional retrospective study of patients who underwent anastomotic posterior urethroplasty by a combined robotic, transabdominal, and open transperineal approach between January 2012 and December 2018. Patient demographics; preoperative, intraoperative, and postoperative clinical data; and complications were reviewed. Urethroplasty success, de novo stress urinary incontinence (SUI), and de novo erectile dysfunction (ED) were evaluated. Results: Twelve patients were identified with a mean follow-up of 596 (range 73-1618) days. Mean patient age was 65.9 (range 53.4-76.8). Reconstruction required corporal splitting, prostatectomy, and gracilis muscle flap use in one (8.3%), eight (66.7%), and four (33.3%) patients, respectively. Postoperative urinary leak, thromboembolic event, and wound abscess occurred in one (8.3%), one (8.3%), and two (16.7%) patients, respectively. Stenosis recurrence occurred in two patients (16.7%) at a mean 187.5 (20-355) postoperative days. De novo ED and de novo SUI were reported in two (16.7%) and four (33.3%) patients, respectively. Nine patients (75.0%) underwent placement of an artificial urinary sphincter at a mean interval of 359.2 (111-1456) days after the index procedure, with no subsequent erosion. Conclusions: Complex posterior urethroplasty by a combined robotic, transabdominal and open transperineal approach is associated with success and complications rates that are comparable to open techniques and may allow for adjunctive procedures such as prostatectomy. This technique allows for the reconstruction of posterior urethral stenoses that would otherwise have been managed conservatively or with urinary diversion.

Abstract
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.

Efficacy and Incontinence Rates After Urethroplasty for Radiation-induced Urethral Stenosis: A Systematic Review and Meta-analysis. Urology 2021; 152:109-116. [PMID: 33631205 DOI: 10.1016/j.urology.2021.02.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 12/30/2020] [Accepted: 02/05/2021] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To estimate the efficacy of urethroplasty and rates of de novo stress urinary incontinence (SUI) in the specific setting of radiation-induced urethral stenosis. METHODS A systematic search of databases (PubMed and EMBASE) was performed between 1980-2019 (CRD42020144845). Inclusion criteria were: (1) prior pelvic radiotherapy; (2) surgical urethroplasty; (3) rates of successful treatment and/or SUI development and (4) total case number provided. The pooled summary of stenosis resolution rate and SUI were calculated using the random-effects model weighted by the inverse variance. Accessory analyses were performed by reconstructive technique and type of RT. RESULTS Ninety-six studies were identified, of which 8 retrospective studies met inclusion criteria, comprising 256 patients. The proportion of cases treated with external beam RT (EBRT), brachytherapy (BT), or combination (EBRT+BT) were 52%, 33%, and 15%, respectively, of studies that specified modality. Most strictures involved the bulbomembranous region (n = 212; 83%). Sixty-one percent of cases (n = 157) entailed primary anastomosis, while the remainder underwent augmentation reconstruction (graft or flap). The mean follow-up time after urethroplasty varied from 10 to 50.5 months. The pooled stenosis resolution rate was 80% (95% CI: 74%-86%). There were no significant associations between stenosis resolution rate and reconstructive technique (rho=0.20, P = .74) or RT modality (rho=-0.31, P = .53). Fifty-three cases developed subsequent SUI, with a pooled complication rate of 19% (95% CI: 10%-31%). CONCLUSIONS Urethroplasty after radiation-induced urethral stenosis is effective for 80% of cases, independent of prior RT modality or urethroplasty technique; however, 1 out of every 5 patients develops SUI post-procedure.

Multi-institutional Outcomes and Associations After Excision and Primary Anastomosis for Radiotherapy-associated Bulbomembranous Urethral Stenoses Following Prostate Cancer Treatment. Urology 2021; 152:117-122. [PMID: 33556448 DOI: 10.1016/j.urology.2020.11.077] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 11/28/2020] [Accepted: 11/30/2020] [Indexed: 01/12/2023]
Abstract
OBJECTIVE To evaluate the outcomes of excision and primary anastomosis (EPA) for radiation-associated bulbomembranous stenoses using a multi-institutional analysis. The treatment of radiation-associated urethral stenosis is typically complex owing to the adverse impact of radiation on adjacent tissue. METHODS An IRB-approved multi-institutional retrospective review was performed on patients who underwent EPA for bulbomembranous urethral stenosis following prostate radiotherapy. Preoperative patient demographics, operative technique, and postoperative outcomes were abstracted from 1/2007-6/2018. Success was defined as voiding per urethra without the need for endoscopic treatment and a minimum follow-up of 12 months. RESULTS One hundred and thirty-seven patients from 10 centers met study criteria with a mean age of 69.3 years (50-86), stenosis length of 2.3 cm (1-5) and an 86.9% (119/137) success rate at a mean follow-up 32.3 months (12-118). Univariate Cox regression analysis identified increasing patient age (P = .02), stricture length (P <.0001) and combined modality radiotherapy (P = .004) as factors associated with stricture recurrence while body mass index (P = .79), diabetes (P = .93), smoking (P = .62), failed endoscopic treatment (P = .08) and gracilis muscle use (P = .25) were not. On multivariate analysis, increasing patient age (H.R.1.09, 95%CI 1.01-1.16; P = .02) and stenosis length (H.R.2.62, 95%CI 1.49-4.60; P = .001) remained associated with recurrence. Subsequent artificial urinary sphincter was performed in 30 men (21.9%), of which 25 required a transcorporal cuff and 5 developed cuff erosion. CONCLUSIONS EPA for radiation-associated urethral stenosis effectively provides unobstructed instrumentation-free voiding. However, increasing stenosis length and age are independently associated with surgical failure. Patients should be counseled that further surgery for incontinence may be necessary.

Abstract
INTRODUCTION From May to December 2019, a literature review of the urinary system iatrogenic injury problem was performed. The most cited, representative articles in PubMed, Scopus, and WoS databases dedicated to this problem were selected. Urinary system iatrogenic injuries include ureter, bladder, urethra, and kidney traumas. It is widely thought that the main causes of such injuries are urological, obstetric, gynecological, and surgical operations on the retroperitoneal space, pelvis, or perineum. METHODS The purpose of the study is to describe all aspects of the iatrogenic injure problem, under the established scheme and for each of the most damaged organs: the urethra, bladder, kidney, and ureter. The treatment of confirmed iatrogenic injuries largely depends on the period of its detection. Modern medical procedures provide conservative or minimally invasive treatment. An untimely diagnosis worsens the treatment prognosis. "Overlooked" urinary system trauma is a serious threat to society and a particular patient. Thus, incorrect or traumatic catheterization can lead to infection (RR 95%) and urethral stricture (RR ≥11-36%), and percutaneous puncture nephrostomy can cause the risk of functional renal parenchyma loss (median 5%), urinary congestion (7%), or sepsis (0.6-1.5%). RESULTS Lost gain, profits, long-term and expensive, possibly multistage treatment, stress and depression, and the risks of suicide put a heavy financial, moral, and ethical burden on a person and society. Also, iatrogenic injury might have legal consequences. DISCUSSION/CONCLUSION Thus, the significant problem of urinary tract iatrogenic injuries is still difficult to solve. There is a need to implement mandatory examining algorithms for patients at risk, as well as the multidisciplinary principle for all pelvic surgery.

Abstract
Aims This article reviews the clinical outcomes and basic science related to negative effects of radiotherapy (RT) on the lower urinary tract (LUT) when used to treat pelvic malignancies. Methods The topic was discussed at the 2019 meeting of the International Consultation on Incontinence―Research Society during a “think tank” session and is summarized in the present article. Results RT is associated with adverse effects on the LUT, which may occur during treatment or which can develop over decades posttreatment. Here, we summarize the incidence and extent of clinical symptoms associated with several modes of delivery of RT. RT impact on normal tissues including urethra, bladder, and ureters is discussed, and the underlying biology is examined. We discuss innovative in vivo methodologies to mimic RT in the laboratory and their potential use in the elucidation of mechanisms underlying radiation‐associated pathophysiology. Finally, emerging questions that need to be addressed through further research are proposed. Conclusions We conclude that RT‐induced negative effects on the LUT represent a significant clinical problem. Although this has been reduced with improved methods of delivery to spare normal tissue, we need to (a) discover better approaches to protect normal tissue and (b) develop effective treatments to reverse radiation damage.

Abstract
PURPOSE To critically evaluate a multi-institutional patient cohort undergoing Dorsal-Onlay Buccal Mucosal Graft Urethroplasty (D-BMGU) for recurrent post-radiation posterior urethral stenosis. METHODS Retrospective multi-institutional review of patients with posterior urethral stenosis from 10 institutions between 2010-2019 was performed. Patients with at least 1-year follow-up were assessed. Patient demographics, stenosis characteristics, peri-operative outcomes, and post-operative clinical and patient-reported outcomes were analyzed. The primary outcomes were stenosis recurrence and de-novo stress urinary incontinence (SUI). Secondary outcomes were changes in voiding, sexual function, and patient-reported satisfaction. RESULTS Seventy-nine men with post-radiation urethral stenosis treated with D-BMGU met inclusion criteria. Median age and stenosis length were 72 years, (IQR 66-75), and 3.0 cm (IQR 2.5-4 cm), respectively. Radiation modalities included: 36 (45.6%) external beam radiotherapy (EBRT), 13 (16.5%) brachytherapy (BT), 10 (12.7%) combination EBRT/BT, and 20 (25.3%) EBRT/radical prostatectomy. At a median follow-up of 21 months (IQR 13-40), 14 patients (17.7%) had stenosis recurrence. Among 37 preoperatively-continent patients, 3 men (8.1%) developed de-novo SUI following dorsal onlay urethroplasty. Of 29 patients with preoperative SUI all but one remained incontinent post-operatively (96.6%). Following repair, patients experienced significant improvement in PVR (92.5 to 26 cc, p = 0.001) and Uroflow (4.6 to 15.9 cc/s, p = 0.001), and high overall satisfaction, with 91.9% reporting a GRA of + 2 or better). CONCLUSION Dorsal onlay buccal mucosa graft urethroplasty is a safe and feasible technique in patients with post-radiation posterior urethral stenosis. This non-transecting approach may confer low rates of de-novo SUI. Further research is needed to compare this technique with excisional urethroplasty.

Abstract
OBJECTIVES To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. PATIENTS AND METHODS Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan-Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). RESULTS Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65-74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28-68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. CONCLUSION The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.

Abstract
PURPOSE OF REVIEW Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries. We review the literature focusing on the anatomy of membranous urethra and on the evolution of treatments for membranous urethral strictures. RECENT FINDINGS Non-traumatic strictures affecting bulbomembranous urethra are typically sequelae of instrumentation, transurethral resection of the prostate, prostate cancer treatment, and pelvic irradiation. Being a different entity from trauma-related injuries where urethra is not in continuity, a new understanding of membranous urethral anatomy is necessary for the development of novel reconstruction techniques. Although efficacious and durable to achieve urethral patency, classical bulboprostatic anastomosis carries a risk of de-novo incontinence and impotence. Newer and relatively less invasive reconstructive alternatives include bulbar vessel-sparing intra-sphincteric bulboprostatic anastomosis and buccal mucosa graft augmented membranous urethroplasty techniques. The accumulated experience with these techniques is relatively scarce, but several published series present promising results. These approaches are especially indicated in patients with previous transurethral resection of the prostate in which sparing of rhabdosphincter and the cavernous nerves is important in attempt to preserve continence and potency. Additionally, introduction of buccal mucosa onlay grafts could be especially beneficial in radiation-induced strictures to avoid transection of the sphincter in continent patients, and to preserve the blood supply to the urethra for incontinent patients who will require artificial urinary sphincter placement. The evidence regarding erectile functional outcomes is less solid and this item should be furtherly investigated.
