Klein R, Vasan R, Guercio C, Rusilko P. Minimally Invasive Management of Posterior Urethral Stricture/Stenosis with DVIU and Mitomycin C Injection. Urology 2024; 183:e317-e319. [PMID: 37866650 DOI: 10.1016/j.urology.2023.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 10/08/2023] [Accepted: 10/11/2023] [Indexed: 10/24/2023]
Abstract
OBJECTIVE To demonstrate a technique for minimally invasive endoscopic management of posterior urethral strictures, including those at the bladder neck and vesicourethral anastomosis. METHODS Herein, we have included endoscopic video footage from 3 patients with posterior urethral strictures, including 1 at the bladder neck, 1 at the vesicourethral anastomosis, and 1 in the bulbomembranous urethra. In each patient, we perform a direct visualization internal urethrotomy (DVIU) with incisions at the 5 and 7 o'clock positions to widen the urethral lumen, followed by injection of 2 mg mitomycin C (MMC) in a total volume of 5 mL sterile water. RESULTS Herein, we describe our technique for the endoscopic management of posterior urethral strictures, including those in the prostatic urethra and bladder neck. MMC injection, in conjunction with traditional DVIU, adds minimally to the complexity and length of the procedure but may substantially improve long-term surgical outcomes. CONCLUSION Bladder outlet obstruction due to stenosis or stricture of the posterior urethra is a common urologic diagnosis whose etiology can often be traced to prior urethral manipulation or iatrogenic trauma. While Americal Urological Assicuation (AUA) guidelines state that dilation or direct visualization internal urethrotomy (DVIU) should be offered for bulbar strictures measuring less than 2 cm in length, recent evidence suggests that DVIU with or without MMC injection may have utility in the management of bladder neck or vesicourethral anastomotic contractures. We have found that DVIU with subsequent MMC injection is a viable minimally invasive approach for the treatment of posterior urethral strictures. While more data are needed to better understand the long-term success rates of these procedures, this approach should be considered for patients with a bladder outlet obstruction secondary to a short stricture of the posterior urethra, bladder neck, or vesicourethral anastomosis.

Abstract
BACKGROUND The aim of the study was to assess whether the risk of perioperative complications after urethroplasty was affected by hospital annual surgical volume (ASV). METHODS In the Nationwide Inpatient Sample, we searched for patients who underwent urethroplasty between 2001 and 2015. Hospitals were categorized into empirically determined tertiles, according to ASV of performed urethroplasties and divided into low (<3) (LVC), intermediate (3-19) (IVC) and high (>20) volume centers (HVC). Multivariable logistic regression (MLR) analyses examined the effect of ASV on perioperative complications and on four specific sub-types of post-operative complications. RESULTS A weighted estimate of 39 912 patients underwent urethroplasty in the US. 34.9% were operated in HVC, while the rate of performed urethroplasties increased in LVC and decreased in HVC. Overall, 1.1%, 18.8% and 2.1% patients respectively experienced intraoperative, post-operative, and transfusions complications. At MLR, IVC and LVC were associated with higher risk of both intraoperative (IVC: OR 2.65, P=0.0008; LVC: OR 4.98, P<0.0001), post-operative (IVC: OR 1.14, P=0.01; LVC: OR 1.26, P=0.001) and transfusions complications (IVC: OR 1.85, P<0.001; LVC: OR 3.03, P=0.01). LVC was also associated with higher risk of hematuria (OR 3.77), urinary infections (OR 1.60) and sepsis (OR 2.83) complications. CONCLUSIONS Approximately 65% of patients were operated in IVC and LVC, and patients treated in IVC or LVC had higher risk of developing both intra and post-operative complications. These data provide important indicators for policy makers to categorize institution based on urethroplasty outcomes.

Abstract
Current therapeutic modalities to treat urethral strictures are associated with several challenges and shortcomings. Therefore, significant strides have been made to develop strategies with minimal side effects and the highest therapeutic potential. In this framework, electrospun scaffolds incorporated with various cells or bioactive agents have provided promising vistas to repair urethral defects. Due to the biomimetic nature of these constructs, they can efficiently mimic the native cells’ niches and provide essential microenvironmental cues for the safe transplantation of multiple cell types. Furthermore, these scaffolds are versatile platforms for delivering various drug molecules, growth factors, and nucleic acids. This review discusses the recent progress, applications, and challenges of electrospun scaffolds to deliver cells or bioactive agents during the urethral defect repair process. First, the current status of electrospinning in urethral tissue engineering is presented. Then, the principles of electrospinning in drug and cell delivery applications are reviewed. Finally, the recent preclinical studies are summarized and the current challenges are discussed.

[PMID: 36042279 PMCID: PMC9428161 DOI: 10.1038/s41598-022-19141-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 08/24/2022] [Indexed: 11/28/2022] Open
Abstract
Urethral stricture is related to scar tissue fibrosis, but its pathogenesis is still unclear. This study aims to explore the regulatory mechanism of circular RNA (circRNA) in the occurrence and development of urethral stricture. CircRNA microarray was employed to analyze circRNA expression profiles between human urethral scar tissue and normal urethral tissue. The results of circRNA microarray showed that there were 296 differentially expressed genes between urethral scar tissue and normal urethral tissue. The enrichment analysis of Kyoto encyclopedia of genes and genomes showed that these circRNAs were significantly correlated with ECM–receptor interaction. The first nine differentially expressed circRNA were selected to predict the circRNA–miRNA network. RT-qPCR results showed that circ_0047339 was upregulated considerably in urethral scar tissue. Urethral scar fibroblasts were isolated from human urethral scar tissue and cultured in vitro. After silencing circ_0047339, the proliferation of urethral scar cells decreased significantly, and the expressions of Collagen I (COL-1) and α-smooth muscle actin (α-SMA) also reduced. As a competing endogenous RNA, circ_0047339 could increase the expression of TSP-1 by competitively binding miR-4691-5p. In addition, miR-4691-5p mimic transfection could inhibit the proliferation of urethral scar fibroblasts and the presentation of thrombospondin-1 (TSP-1), α-SMA and COL-1, while circ_0047339 overexpression eliminated this inhibition. Our results showed that circ_0047339 might promote the growth and fibrosis of urethral scar fibroblasts through miR-4691-5p/TSP-1 axis, thus promoting the development of urethral stricture.

Abstract
OBJECTIVE To assess U-score individual values as urethral complex surgery predictors. METHODS Cross-sectional study including patients who received anterior urethroplasty from 2011 to 2019. U-score (etiology (1-2 points), number of strictures (1-2 points), anatomic location (1-2 points) and length (1-3 points)) was measured individually and globally. Surgical complexity was defined as low (anastomotic, buccal mucosal graft, and augmented anterior urethroplasty), and high complexity (double buccal mucosal graft, flap, and graft/flap combination). U-score components were included as complex surgery predictor and as main variable with individual probability values estimations and comparisons. Risk complex surgery probability groups were established. RESULTS 654 patients were included. Mean age was 57.2 years. Low complexity surgery was performed in 464 patients (259 anastomotic, 144 graft, 61 augmented anterior urethroplasty) and high complexity was done in 190 (53 double buccal mucosa graft, 27 flap, 110 graft/flap comb.). In multivariate analysis length, number of strictures and location were predictors of complexity. Introducing U-Score as only variable in univariate model predicted an OR 8.52 (95%CI 6.1-11). Simplified U-score grouping set obtained by complex probability was: low risk (4-5 points), medium risk (6 points) and high risk of complexity (7-9 points) Predicted risk of complex surgery probability (95%CI) for low, median and high risk group were 1.6 (0-2.9), 19.1 (13.8-25.9) and 77.9 (61.6-88.7), respectively. CONCLUSIONS U-score can be used as a tool to predict complex urethral surgery. We present a simplified U-score risk tool to assess individual complex anterior urethroplasty probability.

Abstract
AIM To summarize available data focused on diagnosis and management of urethral stricture in men with neurogenic lower urinary tract dysfunction by a systematic review of the literature. MATERIALS AND METHODS A systematic review of the literature was carried out through an extensive electronic database search performed in PubMed/MEDLINE and Scopus databases for full texts, and International Continence Society, American Urology Association, and European Association of Urology abstracts for citations related to urethral structure. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. RESULTS A total of 316 articles were identified, 48 of which were selected for this review. Different strategies are currently being used for the management of urethral strictures, such as clean intermittent catheterization (CIC) which reduces stricture by up to 68%; direct vision internal urethrotomy which shows lower rates of renarrowing; urethroplasty which shows a success rate up to 70%; urinary diversion is the treatment of choice when reconstruction is not possible. CONCLUSIONS Further studies are needed in this population because of the heterogeneity of the outcomes and the lack of a standardized definition and classification of this population.

Abstract
Fibrotic diseases of the genitourinary tract are devastating and incompletely understood pathologies. These diseases include urethral and ureteral strictures, retroperitoneal fibrosis, and Peyronie's disease. They can contribute to obstructive uropathy and sexual dysfunction. Poor understanding of the pathophysiology of these diseases severely limits our ability to prevent and treat them. Genitourinary fibrotic diseases likely represent related pathologies that share common underlying mechanisms involving wound healing in response to injury. These diseases share the common feature of extracellular matrix abnormalities-such as collagen deposition, transforming growth factor-β accumulation, and dysregulation of collagen maturation-leading to abnormal tissue stiffness. Given the association of many of these diseases with autoimmunity, a systemic pro-inflammatory state likely contributes to their associated fibrogenesis. Herein, we explore the immunologic contribution to fibrogenesis in several fibrotic diseases of the genitourinary system. Better understanding how the immune system contributes to fibrosis in these diseases may improve prevention and therapeutic strategies and elucidate the functions of immunologic contributors to fibrosis in general.

Abstract
OBJECTIVES Penile urethral stricture disease not associated with hypospadias is rare, and there is a wide range of commonly used surgical repair techniques for this disease. We sought to compile a multi-institutional database of patients who had surgical correction of strictures in the penile urethra not limited to the meatus, and who had no history of hypospadias, for analysis using the Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology classification system. METHODS A retrospective database from 13 institutions was compiled of patients who had undergone surgical correction of Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology urethral stricture segments S2b/S2c and excluding E5, with a minimum follow-up time of 4 months. Failure was defined as cystoscopically confirmed recurrence of a stricture measuring less than 16-Fr. RESULTS We analyzed 222 patients with a median age of 57 years and a follow-up of 49 months. The overall surgical success rate was 80.2%. On multivariate analysis, the two variables identified that were predictive of surgical success were stricture length ≤2 cm as well as use of a buccal mucosa graft as compared to use of a fasciocutaneous flap, which had success rates of 83% and 52%, respectively (P = 0.0004). No statistically significant differences were found based on incisional approach or surgical technique, nor were outcomes different based on etiology or preoperative patient demographics. CONCLUSIONS Surgical repair of penile urethral strictures of non-hypospadiac origin have a favorable overall success rate, at 80.2%. Regardless of incisional approach or surgical technique, all operations appear to have similar outcomes other than repairs using fasciocutaneous flap, which were statistically less successful than those using buccal mucosa graft.

Abstract
BACKGROUND Urethral strictures represent the most frequent long-term complication in men after history of hypospadias surgery. OBJECTIVES To better define the spectrum of men previously treated for hypospadias during childhood, presenting at an adult urology clinic with persistent urethral complications. STUDY DESIGN Retrospective review of the records of 42 consecutive adult patients with a personal history of hypospadias repair during childhood referred at one adult tertiary urology center between 2004 and 2017. Those with persistent urethral strictures were included: 28 patients (median age 28yr [17-81]). Residual chordee, aesthetic concerns, isolated fistulas, and motives of consultation unrelated to hypospadias were excluded. Early initial success rate and location of urethral stricture were studied. Statistical Analysis was done by non-parametric tests. RESULTS On the 42 consecutive adults eligible, a total of 28 patients had a persistent urethral stricture. During childhood, 13/28 boys had required multiple surgical revision procedures, including six of them for postoperative urethral strictures. During adulthood, initial urethral assessment revealed 29 urethral strictures in 28 patients (penile urethra 23/29, bulbar urethra 8/29). The early initial success rate of stricture treatment was 50% (median follow-up: 4 years [1-7]). Additional surgical procedures were needed and performed in 11 patients. Eight patients were eventually diagnosed with a bulbar stricture, either isolated (n = 5) or combined with a distal stricture (n = 3), without significant relationship with initial position of meatus. DISCUSSION Predictive factors for bulbar strictures locations could not be identified. It was however observed that symptomatic bulbar strictures do exist in adults, in the long term after penile hypospadias repair during childhood, independently of the initial site of hypospadias, initial success of primary repair, and the type of surgical reconstructions performed during childhood. CONCLUSION Bulbar strictures represent more than 25% of the overall strictures diagnosed in adult patients treated for hypospadias during childhood, independently of the original site of urethral reconstruction.

Front Public Health 2022; 9:794451. [PMID: 35004597 PMCID: PMC8739884 DOI: 10.3389/fpubh.2021.794451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 11/30/2021] [Indexed: 11/25/2022] Open
Abstract
Background: Male urethral stricture is a disease with a high incidence rate. With social-economic development in the developing countries, the trend of etiology and treatment of male urethral stricture changed was speculated. Methods: The clinical data of the male patients with urethral stricture from 2000 to 2019 were analyzed. The subjects were divided into Group A (2000–2009) and Group B (2010–2019) according to treatment time. The pooled analysis of the data extracted from pieces of literature was also performed. Results: About 540 patients were included in the present study, including 235 patients in Group A and 305 patients in Group B. In recent 10 years, trauma has still been the main cause of urethral stricture. Iatrogenic injury, especially transurethral operation, increases significantly, while male urethral stricture secondary to radiotherapy and infection decrease. Urethroplasty increases and the reoperation rate decreases in treating simple urethral stricture, and flap urethroplasty also increases in treating complex urethral stricture. The results of a pooled analysis of data from 11 centers in Mainland China are partially consistent with it. Complications, such as urethral fistula, false canal, ejaculation disorder, and penile curvature, decrease significantly. Conclusions: The main causes of urethral stricture in the recent 10 years are still trauma and iatrogenic injuries, and the etiology of urethral stricture is related to socioeconomic development. With the increase of intracavitary minimally invasive treatment and flap urethroplasty, the curative effect is increasing, while iatrogenic urethral stricture cannot be ignored.

Abstract
Background Urethral stricture is a relatively frequent problem often requiring multiple surgical interventions. The objective of this study was to compare the clinicopathologic features of urethral resections from patients who underwent open end-to-end anastomotic urethroplasty and later recurred compared to those who did not. Methods A retrospective review of the pathology files identified 36 consecutive patients who underwent urethroplasty. The histopathological analysis included evaluation of the inflammatory infiltrate based on the predominant (>50%) cell type: lymphocyte-rich, neutrophil-rich, plasma cell-rich, and mixed; length and thickness of the fibrous plaque; and the cellularity of the fibrous plaque: cellular (>40 stroma nuclei/HPF) or paucicellular (<40 stroma nuclei/high power field). Results Ten (28%) patients recurred, and 26 (72%) did not. There was no significant difference between recurrent and non-recurrent cases in age, race, comorbidities, location of the stricture, and etiology. All patients with recurrent strictures showed dense paucicellular fibrotic plaques (10/10; 100%), while this was seen in 14/26 (53.8%) non-recurrent cases (P=0.01). Only one patient with cellular fibrosis showed recurrence during follow-up. The log-rank test shows that time to recurrence is significantly shorter in patients with paucicellular fibrosis compared to those with cellular fibrosis (P=0.036). The inflammation consisted of a mixed population of CD3(+) T-lymphocytes, CD20(+) B-lymphocytes, and CD68(+) histiocytes, and there was no difference in the composition of the inflammation between groups. All cases with plasma cell-rich infiltrate showed normal IgG4:IgG. Conclusions Our study supports reporting cellularity of the fibrous plaque as a potential predictor of outcome in patients undergoing reconstructive urethroplasty. Patients with paucicellular fibrosis are at increased risk of recurrence.

Abstract
OBJECTIVE The purpose of this first french guideline is to provide a clinical framework for the diagnosis, treatment and follow-up of anterior urethral strictures. The statements are established by the subgroup working on uro-genital reconstruction surgery (GURU) from the CAMS-AFU (Andrology and Sexual Medicine Committee from the French Association of Urology). MATERIAL AND METHODS These guidelines are adapted from the Male Urethral Stricture : American Urological Association Guideline 2016, updated by an additional bibliography from January 2016 to December 2019. Twenty-seven main scenarios seen in clinical practice are identified: from diagnosis, to treatment and follow-up. In addition, this guidelines are powered by anatomical diagrams, treatment algorithms, summaries and follow-up tables. RESULTS Anterior urethral strictures are a common condition (0,1 à 1,4 %) in men. The diagnosis is based on a trifecta including an examination with patient reported questionnaires, urethroscopy and retrograde urethrography with voiding cystourethrography. Short meatal stenosis can be treated by dilation or meatotomy, otherwise a urethroplasty can be performed. First line treatment of penile strictures is urethroplasty. Short bulbar strictures (<2cm) may benefit from endourethral treatment (direct visual internal urethrotomy or dilation). In case of recurrence or when the stenosis measures more than 2 cm, a urethroplasty will be proposed. Repeated endourethral treatment management are no longer recommended except in case of palliative option. Urethroplasty is usually done with oral mucosa graft as the primary option, in one or two stages approach depending on the extent of the stenosis and the quality of the tissues. Excision and primary anastomosis or non-transecting techniques are discussed for bulbar urethra strictures. Follow-up by clinical monitoring with urethroscopy, or retrograde urethrography with voiding cystourethrography, is performed at least the first year and then on demand according to symptoms. CONCLUSION Anterior urethral strictures need an open surgical approach and should be treated by urethroplasty in most cases. This statement requires a major paradigm shift in practices. Training urologist through reconstructive surgery is the next challenge in order to meet the demand.

Cell-Seeded Acellular Artery for Reconstruction of Long Urethral Defects in a Canine Model. Stem Cells Int 2021; 2021:8854479.

Abstract
The management of urethral stricture remains a major therapeutic challenge in clinics. Herein, we explored the feasibility of reconstructing a relatively long segment of the urethra by the cell-seeded acellular artery in a canine model. The acellular arterial matrix was obtained from the excised carotid artery of donor dogs. Autologous adipose-derived stem cells (ADSCs) from 6 male dogs were grown and seeded onto the premade acellular arterial matrix. A 3 cm long segment of the urethra was resected in 12 male dogs. Urethroplasty was performed with the acellular arterial matrix seeded with ADSCs in 6 animals and without cells in 6. Serial urethrography was performed at 1 and 3 months postoperatively. Wide urethral calibers without any signs of strictures were confirmed in all 6 animals in the experimental group. In contrast, urethral stricture was demonstrated in 3 animals in the control group. The graft was highly epithelialized and smooth in the experimental group, while graft contracture and scar formation were showed in the control group. Histologic analysis of the cell-seeded arterial matrix at 1 month confirmed the presence of multilayered urothelium and muscle. The levels of tissue formation developed over time with a progressive increase in muscle content. In contrast, extensive fibrosis and sparse smooth muscle were seen in animals treated with matrix without ADSCs. This study provides preclinical evidence that the ADSC-seeded arterial matrix can be used as a tubularized scaffold in the reconstruction of 3 cm long urethral defect in a male canine model. The ADSC-seeded arterial matrix remodels and regenerates normal-appearing urethral tissue layers over time.

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
Recurrent male anterior urethral stricture disease is a complex surgical challenge that should be managed by reconstructive urologists with experience in stricture management. Diagnosis of recurrence requires both anatomic narrowing and patient symptoms identified on validated questionnaires, with limited role for intervention in asymptomatic treatment “failures”. Endoscopic management has a very specific role in recurrence, and the choice of technique for urethroplasty depends on pre-operative urethrography and cystoscopy. Surgical success depends on addressing patient concerns, complete stricture excision, tissue quality optimization, and the use of multi-stage repair when indicated. Augmentation with genital skin flaps and/or grafts is often required, with buccal mucosa as the ideal graft source if local tissue is compromised. Salvage options including urinary diversion and perineal urethrostomy must also be considered in debilitated patients with severe disease or repeated treatment failures. Unique patient populations including patients with hypospadias and lichen sclerosis are among the highest risk for repeated recurrence and require special care in surgical technique, graft selection, and post-operative management.

Abstract
Background To evaluate erectile and sexual function after pelvic fracture urethral injury (PFUI) by performing a retrospective review of a large multi-center database. We hypothesized that most men will have erectile dysfunction (ED) and poor sexual function following PFUI, which will remain after posterior urethroplasty. Methods Using the Trauma and Urologic Reconstructive Networks of Surgeons (TURNS) database, we identified PFUI patients undergoing posterior urethroplasty. We excluded patients with incomplete demographic, surgical and/or questionnaire data. Sexual Health Inventory of Men (SHIM), Male Sexual Health Questionnaire (MSHQ), and subjective changes in penile curvature were collected before urethroplasty surgery and at follow-up. We performed descriptive statistics for erectile and ejaculatory function using STATA v12. Results We identified 92 men meeting inclusion criteria; median age was 41.7 years and BMI was 26.5. The mechanism of injury was blunt in all patients, and average distraction defect length was 2.3 cm (SD 1.0 cm). In the 38 patients who completed both pre and post-operative SHIM questionnaires, the mean SHIM score was 10.5 (SD 7.0), with 63% having severe ED (SHIM <12). The median follow-up was 5.6 months and the mean post-operative SHIM was 9.3 (SD 6.5), with 68% having severe ED. The mean change in SHIM score was −1.18 (SD 6.29) with 6 (16%) patients reporting de novo ED (≥5 point decrease in score). Of the men with pre-operative MSHQ data, 46/74 (62.1%) had difficulty with ejaculation, 25/35 (71%) had change in penile length, and 6/33 (18%) reported penile curvature. In men with post-operative MSHQ, 19/44 (43%) expressed difficulty with ejaculation, 23/32 (72%) had change in penile length, and 9/33 (27%) reported penile curvature. Conclusions There is a high rate of severe ED, both following PFUI and remaining after posterior urethroplasty. Additionally, rates of ejaculatory difficulty and patient perceived changes in penile length and curvature underscore the complex nature of the impact of these injuries on sexual function beyond simple erectile function.

Abstract
PURPOSE OF THE REVIEW The goal of this paper was to evaluate the impact on erectile and ejaculatory function after anterior and posterior urethroplasty. RECENT FINDINGS With a rise in the use of urethroplasty, its impact on sexual function has come into question. For anterior urethroplasties, some degree of erectile dysfunction is common, but this tends to be transient, with most patients having a resolution of any de novo dysfunction by 12 months. Patients with posterior urethral strictures have a very high rate of erectile dysfunction prior to surgery and may show improvement after urethroplasty. Ejaculatory function tends to improve in patients due to alleviation of obstruction while some patients notice degradation in force of ejaculation. While urethroplasty has a minimal permanent effect on sexual function for most patients, there are some patients who notice improvement and others worsening. Patients should be counseled on these risks prior to urethroplasty.

Abstract
OBJECTIVE At present, excision and primary anastomosis (EPA) urethroplasty is a highly reliable method of reconstruction for short bulbar urethral strictures. Longer strictures are often managed with grafting techniques to ensure a tension-free repair. Here we report our initial experience with a new, extended anastomotic technique for long bulbar strictures that incorporates plication of the ventral corporal bodies to reduce the distance between the urethral ends and obviates the need for grafting. METHODS We reviewed records for all urethroplasties performed by a single surgeon at our institution between January 2018 and February 2020. We identified a cohort of older patients with complex strictures who underwent Extended Primary Anastomosis with Penile Plication (EPAPP). Patient demographics, stricture characteristics, perioperative 75 parameters, and postoperative outcomes were evaluated. RESULTS Of 346 urethroplasty records reviewed, 10 patients (2.9%) underwent EPAPP. Mean stricture length was 3.75 ± 1.4 cm. EPAPP patients were older than those repaired by other techniques (mean age 66.6 vs 55.6, P = .024), and most were not sexually active preoperatively. Postoperative voiding cystourethrogram confirmed urethral patency without extravasation in all patients. At a median follow up of 9.7 months (IQR 8.5-11.5) 8 patients remained asymptomatic after EPAPP alone and 2 patients required a single balloon dilation for stricture recurrence. CONCLUSION EPAPP is a promising alternative option for the management of long bulbar strictures among appropriately selected patients.

Abstract
Background: Frequency of urethral stenosis makes it necessary to develop new innovative methods of treating this disease. This pathology most often occurs in men and manifests itself in painful urination, reduced urine flow, or total urinary retention. This is a condition that requires immediate medical intervention. Methods: Experimental tests were carried out on a rabbit in order to determine the changes of pressure in the urethra system and to estimate the velocity of urine flow. For this purpose, a measuring system was proposed to measure the pressure of a fluid-filled urethra. A fluoroscope was used to observe the deformability of the bladder and urethra canal. Results: Based on these tests, the range of changes in the urethra tube diameter, the pressures inside the system, and the flow velocity during micturition were determined. Conclusions: The presented studies allowed determining the behavior of the urethra under the conditions of urinary filling. The fluid-filled bladder and urethra increased their dimensions significantly. Such large changes require that the stents used for the treatment of urethral stenosis should not have a fixed diameter but should adapt to changing urethral dimensions.
