RESUMEN
BACKGROUND: Urethrocutaneous fistula (UCF) formation is a known complication following hypospadias repair, affecting between 5 and 70% of cases. Moreover, approximately 30% of patients experience refistulization after UCF repair. The use of extracellular matrices, such as AmnioCord, a dehydrated human umbilical cord allograft manufactured by MiMedx®, may mitigate high rates of refistulization. OBJECTIVE: To determine whether the use of AmnioCord during UCF repair is associated with reduced incidence of subsequent UCFs among pediatric patients. DESIGN, SETTING, AND PARTICIPANTS: Electronic medical records were retrospectively reviewed among 60 patients who underwent at least one UCF repair at a pediatric hospital in a large urban setting in the U.S. between January 2012-June 2018. Patients were followed through January 2024. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Adjusted generalized estimating equation regression models were used to assess the association between AmnioCord use and rates of refistulization, while controlling for confounding variables. RESULTS: The number of fistula presentations per patient ranged from one to four; 53.3% had one fistula, 30.0% had two, and 16.6% had three or more. Overall fistula repair success rate was 56.8% but significantly differed by AmnioCord use in adjusted modelling; 69.4% of cases that received AmnioCord were successfully repaired, compared to 47.2% of cases that did not receive AmnioCord. In adjusted models, patients who received AmnioCord had 2.66 times greater odds of surgical success than patients who did not receive AmnioCord (95% CI:1.13-6.24; p = 0.02). CONCLUSIONS: This study demonstrates a positive association between AmnioCord use and successful UCF closure among pediatric patients.

A 70-year-old male came to our clinic with a high fever and left scrotal swelling. Following a diagnosis of left-side epididymitis, antibiotic treatment was started, though the swelling did not improve. Since an additional examination revealed an abscess in the left scrotum, scrotal incision and drainage were performed. Although the symptoms subsided, urine outflow from the incision was observed. The patient then noted that he had inserted a glass ball into the urethral meatus when he was about 30 years old. It was considered that an abscess and fistula had formed due to inflammation caused by the foreign body. Thus a transurethral surgical procedure was used for crushing and removal. The fistula disappeared within three months after the operation and the patient has not been affected by dysuria since that time. Symptoms may appear several years following insertion of a foreign body into the urethra. To the best of our knowledge, the present case is the longest term of indwelling, approximately 40 years, following insertion of a foreign body reported in Japan.

We report on a case of a two-year-old male dog, breed chow-chow, who suffered from urethral fistula as a result of ureterolithiasis. The urethral defect was identified intraoperatively with methylene blue. An autologous regenerative approach was combined with surgical closure of the defect, due to the well-known healing issues of the urethral wall in such conditions. A part of abdominal fat tissue was dissected to produce microfragmented adipose tissue containing mesenchymal stem cells, which was combined with platelet-rich plasma. The final product was applied in the area around the urethral defect closure. One month after the procedure, healing was confirmed with positive-contrast cystography. This therapeutic approach yielded success, and the follow-up period of one year was uneventful. The observed positive outcome of this approach in the canine model may be considered as a starting point for investigating the translational potential of the treatment in human medicine.

INTRODUCTION AND HYPOTHESIS: This video illustrates a rare surgical case involving a urethral diverticulum, urethrovaginal fistula, and mesh erosion. METHODS: We present a 58-year-old patient attending a tertiary care center with a suspected urethrovaginal fistula. Her concerns included stress urinary incontinence (SUI), recurrent urinary tract infection, and vaginal pain. The surgical history was notable for the placement of two different mesh slings during the same procedure to treat SUI. Preoperative evaluation and findings are illustrated in detail. The video uses a high-definition surgical camera to emphasize the initial intraoperative evaluation with localization of the fistula and diverticulum. We then demonstrate the approach to the dissection with the goal of ensuring complete resection of the diverticulum, fistula, and mesh, while preserving healthy tissue for subsequent closure. The utilization of unique and specialized tools for each portion of the procedure is also illustrated. A layered vaginal closure, including a Martius flap, is created to prevent recurrence. RESULTS: The surgery was accomplished without complications. CONCLUSIONS: To our knowledge, concomitant findings of a urethral diverticulum, urethrovaginal fistula, and mesh erosion are unique in the literature. We postulate that this triad could have resulted from the mesh burden in this particular patient.

BACKGROUND: Urethral diverticulum (UD) is a poorly defined anomaly consisting of an outpouching of the urethra. Management without surgical resection is not previously reported in dogs. HYPOTHESIS/OBJECTIVES: Report the outcome of male dogs presented for urinary incontinence with UD treated with an artificial urethral sphincter (AUS). ANIMALS: Eight client-owned dogs with UD treated with an AUS. METHODS: Multicenter retrospective study. Medical records from male dogs with urinary incontinence were reviewed. INCLUSION CRITERIA: diagnosis of a UD by retrograde cystourethrography, cystoscopy, abdominal ultrasonography or contrast computed tomodensitometry (CT) or a combination of these modalities, AUS placement, and at least 1 follow-up. Urinary continence score (UCS) was attributed retrospectively. RESULTS: Median UCS at presentation was 1/5. A contrast cystourethrogram was diagnostic in 8/8 dogs. All diverticula were saccular, and 7/8 were within the prostatic urethra and 1/8 extended up to the membranous urethra. A congenital origin was suspected in 7 dogs and acquired in 1. Concurrent anomalies included renal dysplasia or chronic pyelonephritis (n = 4), bilateral cryptorchidism (n = 3), and pelvic urinary bladder (n = 3). All dogs were poorly/moderately responsive to phenylpropanolamine. Artificial urethral sphincter placement resulted in improvement in continence in all dogs with a median UCS of 4/5 (5/5 in 2/8 dogs, 4/5 in 5/8 dogs, 3/5 in 1/8 dogs). CONCLUSION: Urethral diverticulum should be considered in male dogs with persistent urinary incontinence not responding to medical management. Artificial urethral sphincter placement is an effective therapeutic option that improved continence scores in all dogs.

BACKGROUND: Long-term urinary outcomes after anorectal malformation (ARM) repair are affected by surgical approach and sacral anomalies. This study aimed to compare laparoscopic-assisted anorectoplasty (LAARP) and posterior sagittal anorectoplasty (PSARP) in terms of urinary complications. METHODS: Between 2001 and 2022, 45 patients were treated with LAARP or PSARP. The rectourethral fistula and inflow angle between the fistula and rectum was confirmed by preoperative colonography. The incidence of urinary complications and treatment were compared between the two groups. RESULTS: Four patients (14%) had remnant fistula and five patients (17%) had neurogenic bladder dysfunction in LAARP group, while three patients (18%) had urethral injury in PSARP group. All patients with remnant fistula were asymptomatic and followed without treatment. The incidence of remnant fistula improved between earlier decade and later decade. In all cases with urethral injury, suture repair was performed and no postoperative leakage was noted. All five patients with neurogenic bladder dysfunction had spine abnormalities that required clean intermittent catheterization (CIC) and two were free from CIC finally. CONCLUSIONS: It is important to check inflow angle preoperatively to prevent remnant fistula. For PSARP, meticulous dissection is required when separating fistula from urethra because they create common wall. The most contributing factor to neurogenic bladder is sacral anomalies. Preoperative evaluation and postoperative urinary drainage are important.

OBJECTIVE: To determine urethral outcomes of single-stage metoidioplasty and radial forearm free flap (RFFF) phalloplasty using the labia minora ring flap for urethral lengthening (UL). METHODS: A retrospective review was performed of patients undergoing single-stage metoidioplasty and RFFF phalloplasty utilizing the labia minora ring flap technique. The ring flap consists of endodermal labia minora tissue ventral to the clitoris and surrounding the vaginal introitus. During metoidioplasty, the ring flap accounts for the entirety of UL. During RFFF phalloplasty, the ring flap becomes the pars fixa (PF) urethra. The primary outcomes measured were rates of fistula, stricture, and surgical revision. RESULTS: Between November 2017 and August 2023, 311 patients underwent metoidioplasty or RFFF phalloplasty (mean follow-up 37 months). Of the 69 metoidioplasties, urethrocutaneous fistulas developed in 11 patients (16%); strictures occurred in 4 (6%). Of the 242 phalloplasty patients, there were 71 fistulas (29%), 56 of which resolved spontaneously. Strictures developed in 44 patients (18%). Twenty-five patients (10%) developed both a stricture and fistula. Surgical repair was required in 8/69 (12%) metoidioplasty patients and in 46/242 (19%) RFFF phalloplasty patients for an overall revision rate of 17%. CONCLUSION: UL during metoidioplasty or RFFF phalloplasty can be accomplished in a single stage using the labia minora ring flap with comparable surgical revision rates to previously described techniques. This approach can also be applied to other phalloplasty techniques. Many fistulas of the PF urethra resolve spontaneously. Higher urethral revision rates were seen in phalloplasty compared to metoidioplasty.

INTRODUCTION: The most prevalent complication in hypospadias repair is fistula formation. Adhering to the principle of providing urethroplasty coverage to mitigate fistula occurrence, we implemented a modification by integrating a spongiosum layer between the urethroplasty and the dartos flap. Our hypothesis posited that this approach would result in a reduced fistula formation rate. METHODS: This study is a comparative analysis involving patients under 18 years of age who underwent primary hypospadias repair. The cases were allocated into two groups. In the study group, in addition to performing tubularized incised plate (TIP) repair, a spongiosum layer harvested from both sides of the urethra was used to cover the urethroplasty (modification of the Y-to-I urethroplasty). The control group underwent a standard TIP repair. The primary outcome was to assess urethrocutaneous fistula formation. Secondary outcomes included evaluating the development of meatal stenosis and glans dehiscence, along with assessing cosmetic results by the Hypospadias Objective Penile Evaluation (HOPE) score. RESULTS: Overall, 154 hypospadias cases were included in the study. Eighty-seven patients (56%) were allocated to the study group, and 67 (44%) were allocated to the control group. Urethrocutaneous fistula developed in 3 (3.4%) and 11 (16.4%) patients in the study and control group, respectively (p = 0.006). Glans dehiscence occurred in 2 (2.3%) patients in the study group and 4 (6%) patients in the control group (p = 0.198). Meatal stenosis was observed in 4 (4.6%) patients in the study group and 5 (7.5%) patients in the control (p = 0.452). The mean HOPE score was 59 in both groups (p = 0.36). DISCUSSION: This study details our encounters with the novel modification and compares the results with standard TIP. Our data suggest that adding a layer of spongiosum tissue over the urethroplasty reduces the complication of urethrocutaneous fistula without increasing the occurrence of dehiscence, significant meatal stenosis, or compromising cosmetic outcomes. CONCLUSION: We advocate for implementing the described surgical modification as a viable option for hypospadias repair.

OBJECTIVE: Children with congenital anorectal malformation (CAM) experience challenges with defecation. This study aims to assess defecation in preschool-age children with CAM and to evaluate the correlation between pelvic floor muscle developed assessed by magnetic resonance imaging (MRI) and postoperative defecation. METHODS: We collected clinical data and MRI results from 89 male children with CAM. The bowel function scores for children with Perineal (cutaneous) fistula, Rectourethral fistula(Prostatic or Bulbar), and Rectovesical fistula were computed. MRI scans were subjected to image analysis of the striated muscle complex (SMC). The association between pelvic floor muscle score and bowel function score was examined using the Cochran-Armitage Trend Test. RESULTS: We observed that 77.4% of the SMC scores by MRI for Perineal fistula were good. The Rectourethral fistula SMC score was 40.6% for moderate and 59.4% for poor. The SMC score for Rectovesical fistula was 100% for moderate. Furthermore, 77.4% of patients with Perineal fistula had bowel function scores (BFS) ≥ 17 points. Among those with Rectourethral fistula and Rectovesical fistula, 12.5% and 0 had BFS ≥ 17 points, respectively. An analysis of muscle development and bowel function in patients with Rectovesical fistula, Rectourethral fistula, and Perineal fistula revealed a correlation between SMC development and BFS. Subgroup analysis showed that the Perineal fistula had statistical significance; however, the Rectourethral fistula and Rectovesical fistula were not statistically significant. CONCLUSION: A correlation exists between pelvic floor muscle development and postoperative defecation in children with Perineal fistula.

INTRODUCTION AND OBJECTIVES: Artificial urinary sphincter (AUS) is a treatment option for women with stress urinary incontinence (SUI) after failure of previous surgery or as a primary procedure in severe intrinsic sphincter deficiency (ISD). The aim of the study was to assess the long-term efficacy and risk factors for surgical revision and definitive explantation of AUS laparoscopic implantation in female patients. METHODS: A retrospective review of all women submitted to AUS implantation between April 2005 and March 2023 was conducted. The AUS was implanted via transperitoneal laparoscopic approach, by two experienced surgeons. The primary endpoint was postoperative continence. Continence was defined as no leakage and no pad usage or leakage and/or pad usage with no impact on social life and failure as leakage and/or pad usage impacting social life. As secondary outcomes, clinical predictive factors for AUS revision and definitive explantation were evaluated. RESULTS: In the last 18 years, females with a mean age of 68±12 years-old were submitted to laparoscopic implantation of AUS. Early overall complication rate was 16%, but only one case was Clavien-Dindo ≥3. After a median follow-up of 67 months, 22.2% of the patients needed a device revision, the majority due to mechanical device dysfunction. AUS definitive explantation was performed in 16%, mainly due to urethral/vaginal erosion (9.9%) and infection (6.2%). Patients with age ≥70 years and follow-up ≥10 years significantly predisposed for device revision. At the time of the last follow-up, 72% of the patients were keeping the urinary continency. CONCLUSIONS: Laparoscopic AUS implantation in females is an effective treatment for SUI due to ISD. Meanwhile, adequate patient selection, multidisciplinary evaluation and careful expectation management are essential to achieving good results, concerning their significant complication rate.

INTRODUCTION: Urethrocutaneous fistula (UCF) is a common complication after hypospadias repair with an incidence of 5-10%. Several techniques are described for its repair: small UCFs are frequently corrected by isolation, excision, and closure with apposition of a protective second layer. In 2008 Malone described the PATIO technique: the fistula tract is turned inside out in the urethral lumen preventing contact with passing urine without direct urethral sutures. OBJECTIVE: Aim of our study is to present our outcomes using a modified version of the PATIO technique, with a more reproducible isolation of the tract and without its fixation at the urethral meatus. STUDY DESIGN: We retrospectively reviewed all cases of UCFs corrected with a modified PATIO technique at our center between 2016 and 2020. Data collected from electronical clinical notes were age at UCF closure, location of UCF, presence of meatal stenosis and clinical outcomes. Data are presented as median and IQR. RESULTS: In the study period we performed 425 urethroplasties for distal and mid penile hypospadias. The incidence of UCFs was 7% (30/425) and 25 patients underwent UCF correction with modified PATIO. Median age at repair was 4.5 years (IQR: 2.5-6.2). At a median follow-up of 3 years (IQR: 2-4) recurrence was observed in 5 cases out of 24 with one patient who was lost at follow-up (20.8%). One case was corrected successfully with re-do modified PATIO technique, while 4 are awaiting repair. One cases was lost at follow-up. UFC-recurrence was homogeneously distributed along the study period. DISCUSSION: Risk factors for UCF recurrence are mostly the type of hypospadias, neo-urethral length, and quality of the urethral plate. Among the many existing techniques, we propose a modified version of Malone's PATIO repair. We believe that the use of four stay-suture to isolate the fistula allows a well-defined dissection of the tract along its surface, compared to the use of a single stay-suture. In our experience, there is no need to keep and fix the traction on the fistula tract to the urethral meatus, probably reflecting the efficacy of the fistula closure during the introflection, which is then maintained without traction. Limitations to our study include the retrospective nature of the review, the small sample size of the cohort and the absence of control groups. CONCLUSIONS: Our results appear consistent with literature regarding the efficacy of PATIO principles in treating UCF. Modified PATIO seem to be particularly reproducible, showing encouraging results.

Due to the controversy on the feasibility of laparoscopic-assisted anorectoplasty (LAARP) for the treatment of the anorectal malformation (ARM) with rectobulbar fistula (RBF), this study aimed to compare the outcomes of LAARP and posterior sagittal anorectoplasty (PSARP) for ARM with RBF. Demographic data, postoperative complications, and bowel function of RBF patients who underwent LAARP and PSARP at 2 medical centers from 2016-2018 were retrospectively reviewed. Eighty-eight children with RBF were enrolled, including 43 in the LAARP group and 45 in the PSARP group. There were no significant differences in the sacral ratio (P = .222) or sacral agenesis (P = .374). Thirty-seven and 38 patients in the LAARP and PSARP groups were followed up for a median of 4.14 years. The postoperative complications were comparable between the groups (P = .624), with no cases of urethral diverticulum. The urination of all cases was normal and no evidence of cyst formation was found on MCU or MRI during the follow-up period. The incidence of rectal prolapse was similar between the 2 groups (9.3% vs 17.8%, P = .247). The groups had equivalent Bowel Function Score (15.29 ± 2.36 vs 15.58 ± 2.88, P = .645), but the LAARP group had better voluntary bowel movement (94.6% vs 84.2%, P = .148) by Krickenbeck classification. The intermediate-term outcomes of LAARP show that the urethral diverticulum was rare by the intraluminal incision of the fistular and the bowel function was comparable to that of PSARP in ARM with rectobulbar fistula. However, LAARP was associated with smaller perineal wounds.

Skene's gland duct cysts are benign, asymptomatic bulging interlabial masses that are rarely identified in female newborns. The aetiology is unknown, but it is commonly associated with in utero maternal oestrogen exposure or obstruction or stenosis of the gland duct. We report three unrelated cases of neonatal Skene's gland duct cysts that resolved spontaneously without the need for surgical intervention.

Literature on the management of pelvic fracture urethral injuries (PFUI) in women is scarce. We present a case of PFUI in a woman.A woman in her 50s presented with lower abdominal pain, bleeding per vaginum and inability to void following road traffic accident. Local examination showed mid-urethral transection injury and tear over the left anterolateral aspect of the vagina. Foley's catheter bulb and bony fragments of the fractured pelvis were palpable anteriorly. Imaging revealed bilateral superior and inferior rami fractures with pubic bone diastasis. She underwent external fixation of pelvic bones with primary repair of urethral and vaginal mucosal injury.Intraoperatively external pelvic fixator was applied, following which the bony fragments in the vagina were lifted up (due to the realignment of pelvic bones). Mid-urethral transection injury was repaired using end-to-end anastomotic urethroplasty. Per-urethral catheter and suprapubic catheter were placed. Periurethral tissue and vaginal layers were closed over the urethral repair. The postoperative course was uneventful.External pelvic fixator was removed after 6 weeks of surgery. Micturating cystogram showed no evidence of contrast extravasation. Follow-up at 3 months showed no urinary symptoms with a bell-shaped uroflowmetry curve.

Rectourethral fistula (RUF) is an infrequent but severe complication of the treatment of prostate cancer. Herein, we describe a new surgical approach used successfully in 3 patients that incorporates a partially de-epithelialized mid-perineal scrotal flap (MPSF), used as interposition flap, that can be used in almost every patient with RUF after radiotherapy, regardless of having or not a concomitant posterior urethra or bladder neck stricture or contracture that might require a simultaneous urethroplasty. The interposition flap includes well vascularized subcutaneous fat tissue by distal vascular branches of the internal pudendal vessels that reaches without tension the deep perineum up to the posterior bladder neck. The MPSF is a time efficient procedure that allows excellent access to the bulbar urethra and to the surgical plane between rectum and prostate and it does not require a separate incision for the flap harvesting procedure when required.

BACKGROUND: Posterior urethral valve (PUV) is the most common congenital bladder outlet obstruction in boys, causing renal damage beginning in utero. There are scarce data from Thailand regarding the long-term outcomes of PUV in boys, thus the aim of this study was to examine the presentation, clinical course, complications, outcomes and renal survival in PUV boys. METHODS: We reviewed the medical records of PUV boys treated at the Pediatric Nephrology Clinic, Prince of Songkla University, Thailand, over a 30-year-period. RESULTS: Seventy-seven PUV boys were identified, with a median age at diagnosis of 4.8 months. The most common presentations were urinary tract infection (UTI), poor urine stream and urinary dribbling in 26 (33.8%), 19 (24.7%) and 11 (14.3%) boys, respectively. Renal ultrasound results in 70 boys showed 8 (11.4%) unilateral and 56 (80%) bilateral hydronephroses. Of 72 voiding cystourethrograms, 18 (25.0%) showed unilateral and 22 (30.6%) bilateral vesicoureteral refluxes. 99mTc dimercaptosuccinic acid renal scans in 30 boys showed 12 (40%) unilateral and 8 (26.7%) bilateral renal damage. Fifty-nine (76.6%) boys had 149 UTIs; 42 (54.4%) had recurrent UTI. Forty-eight boys had valve ablation at the median age of 30.3 months. 22 boys (28.6%) developed chronic kidney disease (CKD) at a median age of 15.0 years. CONCLUSION: Of 77 PUV Thai boys, UTI was the most common presentation. Recurrence of UTI and CKD was the most common consequence. Lifelong follow-up for renal and bladder functions is essential for all PUV patients.

PURPOSE OF REVIEW: Female periurethral masses are an uncommon occurrence. The purpose of this review is to describe etiologies of female urethral and periurethral masses and to provide an update on diagnosis and management. RECENT FINDINGS: The most common causes of periurethral and urethral masses in women are urethral caruncles, urethral diverticula, and Skene's gland cysts. Urethral meatal lesions such as urethral caruncles and prolapse can be managed conservatively with topical estrogen therapy and close follow-up or should be excised in the setting of thrombosis, significant or recurrent bleeding, acute urinary retention, or persistent pain. Benign periurethral gland masses, such as Skene's gland cysts, Gartner's duct cysts, and Mullerian duct cysts, remain rare. Recent case series reveal a high rate of surgical management of these lesions with few complications. Urethral malignancy or malignant transformation of benign etiologies are even rarer but can be aggressive in nature and should be treated promptly. SUMMARY: Nonspecific urinary and vaginal symptoms as well as similar physical presentations make diagnosis of urethral and periurethral lesions in females difficult. Magnetic resonance imaging is useful for differentiation of periurethral masses. The decision for conservative or surgical management is typically guided by patient symptom bother, as well as concern for urethral malignancy.

OBJECTIVES: This study aimed to investigate the characteristics of patients who report improvement in quality of life (QOL) related to urinary status after undergoing robot-assisted radical prostatectomy (RARP) for localized prostate cancer. METHODS: We retrospectively reviewed the patients who underwent RARP between May 2010 and May 2021 at our institution and were preoperatively unsatisfied with their urinary status. Patients were grouped as Group 1 (improved patients: "satisfied" with urinary status based on international prostate symptom score QOL [IPSS-QOL] = 0-2 at 12 months after RARP) and Group 2 (unimproved group: "unsatisfied"-IPSS-QOL 3-6). Additionally, the Expanded Prostate Cancer Index Composite (EPIC) urinary subdomains (urinary function, urinary bother [UB], urinary incontinence, and urinary irritation/obstruction [UIR]) and IPSS were evaluated preoperatively and till 12 months after RARP. RESULTS: Of the 237 patients, 72 (30.4%) were Group 1, and 165 (69.6%) were Group 2. Only UB and UIR improved at 12 months after RARP in Group 1, while other EPIC urinary subdomains remained unimproved at 12 months in both groups. On the other hand, IPSS improved at 12 months in both groups. Univariate and multivariate analysis revealed that the nerve-sparing, preoperative low IPSS (<11 vs. ≥11), and low IPSS-QOL (3 vs. 4-6) were associated with improvement in urinary status-related QOL (p < 0.05). CONCLUSIONS: Improvement in UB and UIR are important factors to ascertain improvement in urinary status-related QOL after RARP. Nerve-sparing and preoperative IPSS/IPSS-QOL values are useful predictors of this improvement.

INTRODUCTION: A rectourethral fistula (RUF) is an infrequent complication that can be iatrogenic in most cases. Multiple surgical interventions were described for RUF repair including transsphincteric, transanal, transperineal, and transabdominal approaches. To this day, there is no consensus on a standardized surgery of choice for acquired RUF. MATERIALS AND SURGICAL TECHNIQUE: Our patient was diagnosed with RUF 4 weeks after undergoing laparoscopic low anterior resection for midrectum adenocarcinoma, with failure of conservative treatment. A three-port transabdominal approach was used to dissect the rectoprostatic space and close the fistula orifice on the anterior rectal wall. With the technical impossibility to develop an omental flap, the peritoneum on the posterior vesical wall was carefully dissected to form a rectangular flap pedicled by its inferior aspect. The harvested peritoneal flap was then anchored between the prostate and the rectum. Follow-up imaging showed the absence of RUF, concurrently with total remission of RUF symptomatology. DISCUSSION: Management of acquired RUF can be challenging, especially after failure of conservative treatment. Laparoscopic repair of acquired RUF by vesical peritoneal flap is a valid option for a minimally invasive approach for the treatment of RUF.
