Acquired rectourethral fistulas in adults: a systematic review of surgical repair techniques and outcomes

How to do a transperineal rectovesical fistula repair with dartos flap interposition

Rectovesical fistula (RVF) is defined as an extra-anatomic communication between the rectum and bladder. A multitude of approaches and techniques have been described; however, there is a lack of consensus regarding which of these procedures is the optimal cost-effective, appropriate treatment to perform. We describe the repair of a persistent RVF via a transperineal approach, utilizing the dartos fascia flap, a technique with minimal description in the literature.

Rectal Injury During Radical Prostatectomy: Incidence, Management, and Outcomes in Single-Center Experience

Background: Rectal injury (RI) is a rare yet serious complication of radical prostatectomy (RP). In this study, we aimed to assess the incidence, risk factors, management strategies, and outcomes of RI during RP. Methods: A retrospective analysis was conducted on 382 patients who underwent RP between 2012 and 2024. Cases of RI were identified intraoperatively, and repair techniques, including two-layer rectal wall closure and vesicourethral anastomosis, were recorded. Risk factors, such as prior pelvic surgery and high-risk pathological features, were also analyzed. Postoperative continence status at 12 months was evaluated using daily pad count, and erectile dysfunction was evaluated using the International Index of Erectile Function (IIEF-5) Results: RI was observed in 2.4% of patients (n = 9), and repairs were successfully completed intraoperatively in all cases. During multivariate analysis, the BMI was found to be protective against RI. Among RI patients, one patient developed a rectourethral fistula, which required reoperation and diversion colostomy; however, six months after the closure colostomy, the fistula persisted, and the patient suffered from severe incontinence. The postoperative 12-month IIEF-5 median score was 7. Conclusions: This study highlights the importance of early intraoperative detection and meticulous surgical repair of RI during RP. Diagnostic measures, such as pneumatic testing and rectal wall monitoring, can mitigate postoperative complications. Our findings contribute to a better understanding of RI management and underscore the importance of individualized surgical approaches for high-risk patients.

Rectourethral fistulas after treatment for prostate carcinoma: Update and new management algorithm

Rectourethral fistula (RUF) is associated with poor quality of life related to urinary functional symptoms (pneumaturia, fecaluria, urine passing through the rectum) or urinary tract infections (upper or lower, often recurrent). Most are iatrogenic, occurring after surgery such as radical prostatectomy, where their prevalence ranges from 0.03 in various series. RUF can also occur after radiation therapy administered for prostate cancer. Management of RUF is complex and depends on whether the patient has had previous radiation therapy or not. Different surgical techniques have been evaluated, but currently there is no consensus as to the best approach. The York-Mason technique is preferred for simple RUF in patients without prior irradiation, while for more complex cases, with antecedent irradiation, transperineal approaches with muscular flap interposition are often recommended. Evaluation of quality of life is crucial, because management of RUF can have severe consequences on urinary continence and sexual function. Despite successful anatomical repair, patients often continue to suffer from functional sequalae that affect their quality of life. Although progress has been achieved in the treatment of RUF, a coherent and efficient management algorithm is necessary to standardize the practical aspects and improve the outcomes. This update summarizes the different strategies that are available for management of RUF and underscores the importance of an individualized approach.

Management of acquired prostatic fistulas in adults

PURPOSE

Acquired prostatic fistula (PF) was defined as a connection between the prostatic urethra and the rectum, symphysis, peritoneum, or ending freely in the periprostatic area. This study aims to report our experience with PF presentation, diagnosis, and treatment.

METHODS

From January 2014 to February 2024, we retrospectively analyzed a prospectively maintained database from two urologic university hospitals to identify men with acquired PF. Diagnosis was based on post-intervention symptoms, including pneumaturia, fecaluria, rectal urine leakage, periprostatic inflammation or abscess, completed by radiological assessment using retrograde urethrogram, CT, or MRI. Standard cystoscopy and/or rectosigmoidoscopy assessed bladder and rectal integrity. Patients with post-prostatectomy fistulas were excluded.

RESULTS

Thirteen patients with a mean age of 66.54 ± 7.40 years were identified. The most commonly presenting symptoms were fecaluria/pneumaturia 54%, rectal urine leakage 31%, and recurrent urinary tract infection 31%. The mean time from the initial treatment to fistula development was 22.28 ± 20.53 months (0.1-59 months), and from diagnosis to repair was 3.5 ± 3 months (1-12 months). Cumulative closure rates (success rate) post-first and second attempts were 77% (10 patients) and 92% (12 patients), respectively; one patient declined definitive surgery, maintaining a persistent fistula after bladder drainage.

CONCLUSION

Clinical suspicion and detailed diagnosis are essential for formulating a tailored treatment plan for prostatic fistulas, which are successfully manageable in many patients. Complex cases benefit from a multidisciplinary approach, with individualized therapy based on etiology, severity, and recurrence of PF, facilitating effective closure.

Robotic-Assisted Colovesical Fistula Repair: A Case Report

Colovesical fistulas present a diagnostic and therapeutic challenge, commonly arising from complications of diverticular disease. In our case, a 71-year-old male with colovesical fistula symptoms underwent robotic-assisted surgery for complicated sigmoid diverticulitis. Intraoperatively, meticulous adhesiolysis and fistula repair were performed. Histopathology confirmed diverticular disease. Postoperatively, the patient recovered well. Colovesical fistulas may indicate underlying malignancy in diverticulitis. With a lack of standardized protocols, our case suggests that robotic-assisted surgery offers improved outcomes, better vision, and ergonomics. To conclude, robotic-assisted colovesical fistula repair and sigmoidectomy demonstrated excellent outcomes, suggesting a promising approach for enhanced postoperative recovery.

Radiation-induced recto-urinary fistula: A dreaded complication with devastating consequences

Purpose

This study was undertaken to evaluate our 16-year experience with fistulas between the rectum and urethra or urinary bladder, collectively called recto-urinary fistulas (RUFs), and their devastating consequences in patients treated with radiation for prostate cancer.

Methods

We downloaded the records of all patients with radiation-related RUFS from 2004 to 2020 at our institution using the electronic medical record system. Details concerning patient demographics, clinical presentation, diagnostic approaches and surgical management were obtained and assessed.

Results

We identified a total of seven patients with radiation-induced RUFS: all were male and had an average age of 66 at diagnosis. Each had a history of prostate cancer that was treated with external, internal (i.e.brachytherapy), or combination radiation therapy. No fistulas were noted in patients treated with radiation for another malignancy. Radiation proctitis with rectal ulcer formation occurred in 6 of 7 patients. Common symptoms included fecaluria, pneumaturia, urine leakage via rectum, rectal pain and urinary tract infection. CT scanning was the most useful diagnostic tool. Once confirmed, fistula management included both urinary and fecal diversion in all patients. Only one patient received definitive repair of the fistula. Five others either died before repair could be attempted or had prohibitive co-morbid diseases. One patient declined repair.

Conclusions

Although rare, the development of a recto-urinary fistula is a dreaded complication. Our results indicate that radiation proctitis with rectal ulcer formation precedes fistula formation in most patients and must be aggressively managed. While fecal and urinary diversion can manage fistula symptoms in the majority of patients, definitive fistula repair is only possible in selected individuals.

Laparoscopic repair of acquired rectourethral fistula by vesical peritoneal flap

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.

Outcomes of gracilis muscle interposition for rectourethral fistulas caused by treatment of prostate cancer

BACKGROUND

Gracilis muscle interposition (GMI) has been associated with favorable outcomes in treating complex perianal fistulas. Outcomes of GMI may vary according to the fistula etiology, particularly between rectovaginal fistulas in women and rectourethral fistulas (RUF) in men. The aim of this study was to assess the outcome of GMI to treat RUF acquired after prostate cancer treatment.

METHODS

This retrospective cohort study included male patients treated with GMI for RUF acquired after prostate cancer treatment between January 2000 and December 2018 in the Department of Colorectal Surgery, Cleveland Clinic Florida. The primary outcome was the success of GMI, defined as complete healing of RUF without recurrence. Secondary outcomes were length of hospital stay and postoperative complications.

RESULTS

This study included 53 male patients with a median age of 68 (range, 46-85) years. Patients developed RUF after treatment of prostate cancer with radiation (52.8%), surgery (34%), or transurethral resection of the prostate (TURP) (13.2%). Median hospital stay was 5 (IQR, 4-7) days. Twenty (37.7%) patients experienced 25 complications, the most common being wound infection and dehiscence. Primary healing after GMI was achieved in 28 (52.8%) patients. Fifteen additional patients experienced successful healing of RUF after additional procedures, for a total success rate of 81.1%. Median time to complete healing was 8 (range, 4-56) weeks. The only significant factor associated with outcome of GMI was wound dehiscence (p = 0.008).

CONCLUSIONS

Although the initial success rate of GMI was approximately 53%, it increased to 81% after additional procedures. Complications after GMI were mostly minor, with wound complications being the most common. Perianal wound dehiscence was significantly associated with failure of healing of RUF after GMI.

Pelvic Extirpative Surgery for the "End-Stage Irradiated Bladder"

Men with prostate cancer have the daunting task of selecting from multiple modalities of treatment. The long-term effects of radiation therapy are only now being recognized. For both patients and surgeons, the end-stage irradiated bladder poses numerous problems and challenges. Specifically, irradiated bladders with urosymphyseal fistula, radiation cystitis, and rectourethral fistula are challenging to manage and treat. This review outlines the presentation, workup, and management including cystectomy for these three devastating late complications of radiation therapy. There are special considerations when performing benign cystectomy that are not typically considered during oncologic cystectomy. We discuss an overview of the current literature regarding the "end-stage bladder" resulting from radiation therapy and the important considerations that must be acknowledged when managing these patients. It is shown that many of the less invasive and conservative options ultimately lead to cystectomy. Indeed, our review concludes that cystectomy with urinary diversion is a safe and viable option in select irradiated patients with the goal to improve quality of life.

Incidence of Rectal Injury After Radical Prostatectomy: A Systematic Review and Meta-analysis

Context

Rectal injury (RI) is a dreaded complication after radical prostatectomy (RP), increasing the risk of early postoperative complications, such as bleeding and severe infection/sepsis, and late sequelae, such as a rectourethral fistula (RUF). Considering its traditionally low incidence, uncertainty remains as to predisposing risk factors and management.

Objective

To examine the incidence of RI after RP in contemporary series and to propose a pragmatic algorithm for its management.

Evidence acquisition

A systematic literature search was performed using the Medline and Scopus databases. Studies reporting data on RI incidence were selected. Subgroup analyses were conducted to assess the differential incidence by age, surgical approach, salvage RP after radiation therapy, and previous benign prostatic hyperplasia (BPH)-related surgery.

Evidence synthesis

Eighty-eight, mostly retrospective noncomparative, studies were selected. The meta-analysis obtained a pooled RI incidence of 0.58% (95% confidence interval [CI] 0.46-0.73) in contemporary series with significant across-study heterogeneity (I2 = 100%, p < 0.00001). The highest RI incidence was found in patients undergoing open RP (1.25%; 95% CI 0.66-2.38) and laparoscopic RP (1.25%; 95% CI 0.75-2.08) followed by perineal RP (0.19%; 95% CI 0-276.95) and robotic RP (0.08%; 95% CI 0.02-0.31). Age ≥60 yr (0.56%; 95% CI 0.37-06) and salvage RP after radiation therapy (6.01%; 95% CI 3.99-9.05), but not previous BPH-related surgery (4.08%, 95% CI 0.92-18.20), were also associated with an increased RI incidence. Intraoperative versus postoperative RI detection was associated with a significantly decreased risk of severe postoperative complications (such as sepsis and bleeding) and subsequent formation of a RUF.

Conclusions

RI is a rare, but potentially devastating, complication following RP. RI incidence was higher in patients ≥60 yr of age, and in those who underwent open/laparoscopic approach or salvage RP after radiation therapy. Intraoperative RI detection and repair apparently constitute the single most critical step to significantly decrease the risk of major postoperative complications and subsequent RUF formation. Conversely, intraoperatively undetected RI can lead more often to severe infective complications and RUF, the management of which remains poorly standardised and requires complex procedures.

Patient summary

Accidental rectum tear is a rare, but potentially devastating, complication in men undergoing prostate removal for cancer. It occurs more often in patients aged 60 yr or older as well as in those who underwent prostate removal via an open/laparoscopic approach and/or prostate removal after radiation therapy for recurrent disease. Prompt identification and repair of this condition during the initial operation are the key to reduce further complications such as the formation of an abnormal opening between the rectum and the urinary tract.

[Closure of persisting rectourethral fistula after suprasymphyseal adenoma enucleation of the prostate by combining the Bressel-Naujox and gracilis flap procedure]

When taking into consideration the basic principles of fistula surgery, numerous options are available for the surgical repair of rectourethral fistulas. However, there is no standard regarding which surgical method should be used under which circumstances-due to the heterogeneity of this disease. This case report describes the individual adaptation of a surgical technique that is used for the treatment of vesicovaginal fistulas to treat a rectourethral fistula in a patient who had already undergone an unsuccessful fistula closure attempt. Successful closure of the fistula was achieved on the basis of an established method using tissue interposition.

Robotic Simultaneous Repair of Rectovesical Fistula With Vesicourethral Anastomotic Stricture after Radical Prostatectomy: Step-by-Step Technique and Outcomes

OBJECTIVE

To report our experience and outcomes using a novel robotic technique for the simultaneous repair of rectovesical fistula (RVF) with vesicourethral anastomotic stricture (VUAS) after radical prostatectomy (RP).

METHODS

Between 2019 and 2021, four consecutive patients who underwent robotic-assisted simultaneous repair of RVF with concurrent VUAS after RP were retrospectively reviewed. Baseline characteristics and perioperative outcomes were examined and reported. Complications were graded using the modified Clavien-Dindo classification system and the European Association of Urology Complications Panel Assessment and Recommendations.

RESULTS

Four cases with a median age of 68.5 (63.3-72.3) years were treated. Interposition omentum flaps were used in all our cases. One case had perineal urethral mobilization to reach healthy urethral margins and tension-free vesicourethral anastomosis. Surgeries were uneventful, with no intraoperative complications reported. Median operative time, estimated blood loss, and length of hospital stay were 370 (291.3-453) minutes, 255 (175-262.5) mL, and 2.5 (2-3) days, respectively. Median Jackson-Pratt drains, Double-J stents and Foley catheter removal days were 6 (6-10), 38 (32-43), and 30 (27-41) days, respectively. No postoperative complications were reported. The median follow-up time was 16.25 (12-26) months, and no fistula recurrence was shown.

CONCLUSION

Robotic-assisted laparoscopic repair could represent an effective approach for the simultaneous repair of RVF with concomitant VUAS. More studies and management standardization are needed to assess the role of the robotic platform in the simultaneous repair of RVF with VUAS after radical prostatectomy.

Gracilis muscle transposition in complex anorectal fistulas of diverse types and etiologies: long-term results of 60 cases

PURPOSE

Complex fistulas often require several attempts at repair and continue to be a challenging task for the surgeon, but above all, a major burden for the affected patient. This study is aimed at evaluating the potential of gracilis muscle transposition (GMT) as a therapeutic option for complex fistulas of diverse etiologies.

METHODS

A retrospective study was conducted over a period of 16 years with a total of 60 patients (mean age 50 years). All were treated for complex fistula with GMT at St. Josef's Hospital in Regensburg, Germany. Follow-up data were collected and analyzed using a prospective database and telephone interview. Success was defined as the absence of fistula.

RESULTS

A total of 60 patients (44 women, 16 men; mean age 50 years, range 24-82 years) were reviewed from January 2005 to June 2021. Primary fistula closure after GMT was achieved in 20 patients (33%) and 19 required further interventions for final healing. Overall healing rate was 65%. Fistula type was heterogeneous, with a dominant subgroup of 35 rectovaginal fistulas. Etiologies of the fistulas were irradiation, abscesses, obstetric injury, and iatrogenic/unknown, and 98% of patients had had previous unsuccessful repair attempts (mean 3.6, range 1-15). In 60% of patients with a stoma (all patients had a stoma, 60/60), stoma closure could be performed after successful fistula closure. Mean follow-up after surgery was 35.9 months (range 1-187 months). No severe intraoperative complications occurred. Postoperative complications were observed in 25%: wound healing disorders (n = 6), gracilis necroses (n = 3), incisional hernia (n = 2), scar tissue pain (n = 2), suture granuloma (n = 1), and osteomyelitis (n = 1). In 3 patients, a second gracilis transposition was performed due to fistula recurrence (n = 2) or fecal incontinence (n = 1).

CONCLUSION

Based on the authors' experience, GMT is an effective therapeutic option for the treatment of complex fistulas when other therapeutic attempts have failed and should therefore be considered earlier in the treatment process. It should be seen as the main but not the only step, as additional procedures may be required for complete closure in some cases.

Minimally Invasive Management of Rectourethral Fistulae

OBJECTIVE

To report our experience and outcomes in minimally invasive management of rectourethral fistula (RUF).

METHODS

From 2004 to 2021, 15 patients who underwent minimally invasive RUF repair by a single surgeon at 2 international institutions were retrospectively reviewed. Baseline demographic characteristics, perioperative, and postoperative data were collected. Complications were reported using the modified Clavien-Dindo Classification System and the European Association of Urology Complication Panel Assesment and Recommendations. Success was defined as complete resolution of fistula-related symptoms at 12-month follow-up along with confirmation of fistula closure by imaging or cystoscopy. Categorical variables were presented as frequencies and percentages whereas continuous variables were reported as median and quartiles.

RESULTS

Fifteen male patients with a median age of 71 (64-79.2) years were treated. Four cases (26.6%) occurred postsurgery, 8 cases (53.3%) occurred after energy treatments, and 3 cases (20%) after surgery combined with an energy treatment modality. A robotic and laparoscopic approach was performed in 9 (60%) and 6 (40%) patients, respectively. No intraoperative complications were reported. Median operative time was 264 (217.5-341) minutes, estimated blood loss was 175 (137.5-200) mL, and the length of hospital stay was 4 days. Nine postoperative complications were reported. All patients were followed-up for 12 months with no recurrence reported. All patients reached our criteria for successful RUF repair.

CONCLUSIONS

Minimally invasive surgery could represent an efficient way to manage RUF in selected patients. More studies and treatment standardization are needed to assess the role of minimally invasive surgery in the management of RUF.

Long term outcome of multidisciplinary management of urethro-rectal fistula after urologic surgery

Urethro-rectal fistula (URF) is a rare but serious condition whose treatment is poorly codified. This study aims to evaluate the short and long-term results of multidisciplinary management.

MATERIAL AND METHODS

We retrospectively collected the records of patients with URF operated on at the University Hospital of Tours between January 1, 2000 and January 1, 2020. Short-term and long-term results according to management are reported.

RESULTS

The study included 20 patients. As an initial gesture, 11 patients underwent bladder catheterization and colostomy, seven underwent bladder catheterization alone, one underwent graciloplasty, and one, a York Mason procedure. The success rate of initial conservative management was only 5% (1/20). As a secondary or tertiary intervention, ten patients underwent a York Mason procedure and nine underwent graciloplasty. At the end of the study period, with a median follow-up of 50 months, 19 had been effectively treated for URF, 16 were able to have colostomy closure with restoration of digestive continuity while four had a permanent stoma. One patient had anal incontinence, 14% had major stress urinary incontinence.

CONCLUSION

Multidisciplinary care remains a cornerstone of the treatment of URF because iterative surgeries may be required, with an overall success rate of up to 95% at the end of follow-up.

Robotic-assisted laparoscopic repair of a congenital rectourethral fistula with duplicated urethra

OBJECTIVE

To describe our experience with robot-assisted laparoscopic transperitoneal repair of a congenital rectourethral fistula in a pediatric patient with a urethral duplication.

METHODS

The patient is a 2-year-old male with a past medical history of Tetralogy of Fallot presenting with a febrile urinary tract infection (UTI). He was diagnosed with urethral duplication and a rectourethral fistula by voiding cystourethrogram (VCUG). The parents were counseled on various options and agreed to proceed with a robotic repair.

RESULTS

Robotic-assisted transperitoneal rectourethral fistula repair was performed. The procedure time was 229 min with an estimated blood loss (EBL) of 15 mL. His postoperative course was unremarkable. At his 2-week follow-up, the urethral catheter was removed and the patient was voiding normally and having normal bowel movements.

CONCLUSION

Congenital rectourethral fistula with urethral duplication is a rare anomaly with only a few reports in the literature. Pediatric robotic-assisted transperitoneal rectourethral fistula repair is a technically feasible approach in infants with minimal morbidity that allows for excellent visualization and avoids open repair.

Rectourethral Fistula Induced by Localised Prostate Cancer Treatment: Surgical and Functional Outcomes of Transperineal Repair with Gracilis Muscle Flap Interposition

BACKGROUND

Transperineal repair of rectourethral fistula (RUF) following prostate cancer treatment with gracilis muscle flap interposition (GMFI) leads to favourable outcomes, but published data are still lacking, notably concerning functional aspects.

OBJECTIVE

To assess surgical and functional outcomes of this treatment of RUF.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective study was conducted in two referral hospitals including 21 patients who underwent RUF transperineal repair with GMFI between 2008 and 2020.

SURGICAL PROCEDURE

The standard vertical perineal approach is performed for fistula dissection. Bladder and rectal defects are closed separately. After dissection from its facia, the flap is harvested, preserving its pedicle; it is brought to the perineum and placed between the urethra and the rectum to fully cover the sutures.

MEASUREMENTS

Fistula closure (clinical data and postoperative cystography), digestive stoma closure, and complications graded according to the Clavien-Dindo classification were reviewed. Functional results were assessed using the Urinary Symptom Profile (USP) questionnaire, anal incontinence St Mark's score, Patient Observer Scar Assessment Scale (POSAS) score, and a nonvalidated Likert scale questionnaire assessing issues with lower extremity functionality.

RESULTS AND LIMITATIONS

The median (interquartile range) follow-up was 27 (8-47) mo. Fistula closure was successful for 20 patients (95% success). Digestive stoma was closed in 10/12 shunted patients (83%). Two (9%) Clavien-Dindo grade ≥3b complications were reported (one urinoma in a kidney transplant patient and one thigh haematoma evacuation). Eighteen patients (86%) completed the postoperative questionnaire; 11/18 (61%) had significant urinary incontinence. The mean (standard deviation) USP dysuria score was 1/9 (1.2), mean St Mark's score was 5/24 (5), mean POSAS score was 19/70 (11), mean lower extremity functionality score was 2/20 (4), and mean procedure patient satisfaction score was 9/10 (2). The retrospective design and limited number of patients are the main limitations.

CONCLUSIONS

The present study found an excellent success rate and low morbidity for RUF transperineal repair with GMFI. Functional outcomes were satisfactory despite a high urinary incontinence rate.

PATIENT SUMMARY

We performed an analysis of the outcomes of perineal approach surgery with muscle interposition for closing abnormal communication between the bladder and the rectum after prostate cancer treatment. This surgical technique was found to be safe to perform and provides a high success rate, with patients being satisfied despite poor urinary continence outcomes.

Gracilis muscle flap combined with a laparoscopic transabdominal approach is effective in the treatment of post-prostatectomy rectourethral fistula: A case report

Introduction

Case presentation

Clinical discussion

Conclusion

•

The rectourethral fistula is a rare complication of total prostatectomy, but when it becomes intractable, it is difficult to treat. Surgical treatment is required, but there is no standard technique.

•

We used a laparoscopic approach in combination with gracilis muscle flap filling via a transperineal approach.

•

To our knowledge, this technique has only been reported in only one other case in the Japanese literature.

•

In a case of high rectourethral fistula, the gracilis muscle flap with a laparoscopic approach allowed for safe and secure flap filling.

Pelvic Radiation Disease

Pelvic radiation is increasingly being used for the neoadjuvant and definitive treatment of pelvic organ malignancy. While this treatment can be highly effective, and may assist in organ sparing, it is also associated with significant toxicity and devastating adverse events that need to be considered. In broad terms, pelvic radiation disease affects both the primary target organ as well as adjacent organs and soft tissue structures, with complications that can be classified and graded according to consensus criteria. The complication grade is often modality, dose, and area dependent. The most common manifestations are proctitis, cystitis, recto-urethral fistula, ureteric stricture, and bone involvement. Toxicity can be misdiagnosed for many years, resulting in significant management delays. Complications can be difficult to prevent and challenging to treat, requiring specialized multi-disciplinary input to achieve the best possible strategy to minimize impact and improve patient quality of life.

Post-traumatic rectourethral fistula in an adolescent managed via a transperineal approach using a local gluteal tissue interposition flap: a case report

Background

Rectourethral fistula is a rare disease with a wide variety of etiologies and clinical presentations. A definitive surgical procedure for rectourethral fistula repair has not been established.

Case presentation

A 13-year-old boy sustained a penetrating injury to the perineum, and developed a symptomatic rectourethral fistula thereafter. Conservative management through urinary diversion and transanal repair was unsuccessful. Fecal diversion with loop colostomy was performed, and three months later, a fistula repair was performed via a transperineal approach with interposition of a local gluteal tissue flap. There were no postoperative complications, and magnetic resonance imaging studies confirmed the successful closure of the fistula. The urinary and fecal diversions were reverted 1 and 6 months after the fistula repair, respectively, and postoperative excretory system complications did not occur.

Conclusions

The transperineal approach with interposition of a local gluteal tissue flap provides a viable surgical option for adolescent patients with rectourethral fistulas who are unresponsive to conservative management.

A Curious Case of Rectal Ejaculation

Rectal-prostate fistulas are uncommon anatomical connections between the prostatic urethra and rectum that are typically iatrogenic but can also result from other underlying pathology. Here, we present a unique case of a rectal-prostate fistula causing the rectal passage of sperm.

A 33-year-old male with a history of illicit drug use presented with five days of testicular pain and a substantial amount of sperm passage from his rectum with ejaculation for the past two years. Computed tomography and voiding cystourethrogram (VCUG) of the pelvis revealed evidence of a rectal-prostate fistula. He was treated with piperacillin-tazobactam, and a surgical fistula repair was performed. Further investigation divulged a three-week comatose state due to cocaine and phencyclidine intoxication two years prior with documentation suggesting a traumatic Foley catheter placement and strong suspicion for premature balloon dilation in the prostatic urethra. Repeat VCUG revealed resolution of the fistula with mildly reduced antegrade ejaculatory volume.

Cases secondary to Foley catheter placement have not been previously reported in the literature. Even though urethral catheters have been shown to be effective tools in healthcare, it is crucial for clinicians to recognize the numerous potential complications that oftentimes become an afterthought to many providers. This case not only highlights a rare complication of catheter use but also emphasizes the importance of provider mindfulness when utilizing seemingly benign therapies such as Foley catheters.

[Rectourethral fistula treatment using the modified York Mason technique: Failure factors assessment]

OBJECTIVES

To assess surgical outcomes and failure factors in the management of rectourethral fistulas treated surgically with the modified York Mason technique based on our center's 25 years of experience.

METHODS

From 1997 to 2021, in a single center study, a total of 35 consecutive patients, underwent rectourethral fistula cure, using the modified York Mason technique. Preoperative patient data, surgical outcomes and failure factors were assessed.

RESULTS

Of the 35 patients, 28 were successfully managed without the need of further intervention (80%). Median age was 67 years (IQR 62-72) and median follow-up time was 71 months (IQR 30-123). There was no significant difference between the patients that had recurrence or not after the first York Mason.

CONCLUSIONS

The modified York Mason technique offers a high success rate for the cure of iatrogenic rectourethral fistulas. No predictive factor of failure, after a first cure of recto-uretral fistula by modified York-Mason technique was reported.

Video-Endoscopic Mobilization of the Gracilis Muscle for Rectourinary Fistula Repair

INTRODUCTION

Transposition of the gracilis has been used in a large number of reconstructive procedures. Its advantage is its proximity to these defects and a good blood supply. Traditionally, the gracilis mobilization is performed by open surgery with one or more incisions. We describe our initial experience with the video-endoscopic mobilization of gracilis.

METHOD

We described a retrospective review of all patients who underwent gracilis muscle mobilization for treatment of rectourethral fistula, performed by video-endoscopy, between March 2013 and September 2017, for treatment of rectourethral fistula. Also, our surgical technique is described in detail.

RESULTS

Three patients, with a mean age of 66.6 years, underwent the procedures. The mean time for mobilization of the gracilis was 107 min (range 60-145). There was no case of donor area infection, no change in the sensitivity of the medial aspect of the thigh or chronic pain. Conversion to open surgery was not necessary in any case. The hospital discharge occurred in average after 4 days. The bladder catheter was removed after 4 weeks after cystography was performed without evidence of leakage. One patient had a recurrence of the fistula.

DISCUSSION

The gracilis is an excellent choice of tissue to be interposed in reconstructive procedures of the perineal region, especially in the treatment of rectourinary fistulas. However, endoscopic harvest of the gracilis muscle has not yet found its way into everyday practice. The results in the treatment of rectourinary fistulas are excellent, with a success rate of 87.7%. Our rate of 67% is below, probably due to the small number of cases. In open surgery, complications are uncommon; however, approximately half of the patients expressed concern about the painful scar, which can be reduced by minimally invasive access.

CONCLUSION

Video-endoscopic mobilization of gracilis muscle for the treatment of rectourethral fistula is feasible and safe. Studies comparing this technique with the conventional mobilization are required.

Treatment for rectourethral fistulas after radical prostatectomy with biological material interposition through a perineal access

INTRODUCTION

Rectal injury is a rare complication after extraperitoneal laparoscopic radical prostatectomy. The development of rectourethral fistulas (URF) from rectal injuries is one of the most feared and of more complex resolution in urology.

MATERIAL AND METHODS

Between 2013 and 2020 we have operated on a total of 5 patients with URF after extraperitoneal endoscopic radical prostatectomy through a perineal access using the interposition of biological material. All fistulas had a diameter of less than 6 mm at endoscopy and were less than 6 cm apart from the anal margin.

RESULTS

The mean age of the patients was 64 years old. All patients had a previous bowel and urinary diversion for at least 3 months. Under general anesthesia and with the patient in a forced lithotomy position, fistulorraphy and interposition of biological material of porcine origin (lyophilized porcine dermis [Permacol®]) were performed through a perineal access. Mean operative time was 174 min (140-210). Most patients were discharged on the third postoperative day. The bladder catheter was left in place for a mean of 40 days (30-60). Prior to its removal, cystography and a Gastrografin® barium enema were performed, showing resolution of the fistula in all cases.

CONCLUSIONS

The interposition of biological material from porcine dermis through perineal approach is a safe alternative with good results in patients submitted to urethrorectal fistulorraphy after radical prostatectomy.

Acquired Rectourethral and Rectovaginal Fistulas in Children: A Systematic Review

Background: Acquired rectourethral (RUF) or rectovaginal fistulas (RVF) in children are rare conditions in pediatric surgery. Prior literature are retrospective studies and based on a small number of patients. The managements and outcomes vary widely across different studies. No standard or recommended management has been universally adopted. The goal was to systematically summarize different causes, provide an overlook of current clinical trend and to derive recommendation from the literature regarding the etiology, managements, and outcomes of pediatric acquired RUF and RVF. Methods: PubMed, Embase, Cochrane databases were searched using terms: rectourethral fistula, recto-urethral fistula, urethrorectal fistula, urethro-rectal fistula, rectovaginal fistula. All studies were retrospective, in English, and included patients under the age of 18 years. Any series with congenital cases, adult (>18 years), <2 fistula cases less and obstetric related causes were excluded. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline was followed. Results: Of the 531 records identified, 26 articles with 163 patients (63 RUF and 100RVF) were fully analyzed. Most RUF resulted from trauma, most RVF were from infection of HIV. About 92 patients underwent 1 of 3 categories of definitive repair, including transanal (4.3%), trans-sphincteric (48.9%), and transperineal (30.4%). Tissue interposition flaps were used in 37.6% patients, while temporary fecal diversions were used in 63.9% patients. Fistula was successfully closed in 50.3% patients (98.4% RUF and 20% RVF). 89.1 and 79.7 % of surgical repair patients had optimal fecal and urinary functions, respectively. In the inflammatory bowel disease and HIV infection related RVF patient group, the closure rate was prohibitive poor. Conclusions: Most RVF are a sign of systematic diseases like HIV-infection or IBD and are associated with poor general conditions. While conservative treatment is recommended, stable patients can benefit from surgery. Further investigation is recommended if RVF are encountered without trauma or surgical history. RUF are likely to result from trauma or surgery, and transperineal or trans-sphincter approach can lead to closure and optimal function results. Fecal diversion and/or urinary diversion are helpful in some cases, while interposition technique may not be necessary. An objective scoring system for long-term follow-up and reporting consensus is needed to address treatment inconsistence.

Urorectal fistula repair using different approaches: operative results and quality of life issues

PURPOSE

To evaluate efficacy of urorectal fistula (URF) repair using different approaches and the clinical factor determinant of success, and also the morbidity associated to the procedure and health-related quality of life (HRQoL) in male survivors of pelvic malignancies.

MATERIAL AND METHODS

Retrospective evaluation of 39 patients with URF primarily intervened in three institutions using different surgical approaches. Success was defined as effective fistula closure. Variables evaluated included demographics, previous treatments, surgical approach, ancillary surgeries, complications and HRQoL by using a standardized non-validated specific questionnaire. Median follow-up from surgery to interview was 55 months (interquartile range 49, range 4-112). Factors determinant of success were investigated using logistic regression. Safety of the procedure was evaluated by Clavien-Dindo scale. Deterioration of continence and erectile function and other HRQoL issues were evaluated.

RESULTS

Prostate cancer treatment was the predominant etiology. The success rate for fistula repair was 89.5%. The surgical approach was not related to failed repair (p=0.35) or complications (p=0.29). Factors associated with failure were complications (p=0.025), radiotherapy (p=0.03), fistula location (p=0.04) and fistula size (p=0.007). Multivariate analysis revealed fistula size was the only independent determinant of failure (OR 6.904, 1.01-47.75). Complications occurred in 46.2% and severe complications in 12.8%. The mortality related to the procedure was 2.6%. Urinary incontinence was present before repair in 26.3% and erectile dysfunction in 89.5%. Fistula repair caused de novo urinary incontinence in 7.9% and deterioration of erectile status in 44.7%. Globally 79% were satisfied after repair and only 7.9% rated HRQoL as unhappy. Trans-sphincteric approach was related to less deterioration of erectile function (p=0.003), and higher perceived satisfaction in QoL (p=0.04).

CONCLUSIONS

The surgical approach elected to correct URF is not determinant of success nor of complications. Fistula size appears as independent determinant for failure. Trans-sphincteric approach could be advantageous over other procedures regarding HRQoL issues.

Clinical outcome and quality of life after gracilis muscle transposition for fistula closure over a 10-year period

PURPOSE

Gracilis muscle transposition (GMT) is an established surgical technique in the treatment of anorectal fistulas and fistulas to the vagina and the urinary system when previous closure options have failed. There is little evidence on the success rate of this procedure in the long term.

METHODS

This is a follow-up study on all patients undergoing GMT over a 10-year period at a tertiary referral center for complex fistulas. Postoperative function and quality of life were evaluated by standardized questionnaires (Wexner score, Fecal Incontinence Quality of Life Score (FIQL), SF-12 and a brief questionnaire designed for this study). Sexual function was evaluated by the Female Sexual Function Index (FSFI) and the International Index of Erectile Function.

RESULTS

Forty-seven gracilis muscle transpositions (GMT) in 46 patients were performed. Most treated patients had (neo-)-rectovaginal fistulas (n = 29). An overall fistula closure was achieved in 34 of 46 patients (74%): in 25 cases primarily by GMT (53%) and in nine patients with persistent or recurrent fistula by additional surgical procedures. A clinically apparent relapse occurred on average 276 days (median: 180 days) after GMT (mean follow-up 73.4 months).

CONCLUSION

GMT in our hands has a primary closure rate of 53%, and after further procedures, this rises to 74%. Fecal continence is impaired in patients having undergone GMT. The overall quality of life in patients after GMT is only slightly impaired, and sexual function is severely impaired in female patients.

Treatment for rectourethral fistulas after radical prostatectomy with biological material interposition through a perineal access

Rectourethral and rectovesical fistula as serious and rare complications after Hirschsprung disease operation: Experience in seven patients

AIM

To present the features and treatment of rectourethral fistula (RUF) and rectovesical fistula (RVF) after Hirschsprung disease (HD) operation.

METHODS

A retrospective analysis was performed on patients with RUF and RVF after HD operation, who received repair surgery from a single surgeon between January 2005 and December 2019. Bowel function was assessed using the Rintala score.

RESULTS

Seven patients were included. Six patients were referred to us after transanal endorectal pull-through (TEPT) in other centers; one RVF patient had fecal diversion at admission. Bladder-neck injury was detected during redo TEPT in our hospital in the remaining one patient and instant repair was given. 11 days later, RVF and sepsis were detected. Fecal and urine diversion was performed immediately. The fistula openings were prostatic urethra (3), membranous urethra (2), bladder triangle (1), and bladder-neck (1). Anastomotic stricture (4), bladder stone (3), hydronephrosis and ureterovesical junction obstruction (2), pelvic infection (2), distal colonic dilatation (1) and other fistulas (1) were identified before repair surgery. Fecal and urine diversion was performed before repair surgery in one RUF and one RVF patient respectively, to treat pelvic infection owing to fecal or urine leaks and accompanying problems. Five RUFs were repaired by transperineal approach, and two RVFs were repaired using the transabdominal and transanal approach respectively. Four patients with anastomotic stricture underwent redo TEPT with simultaneous fistula repair. Aside from one RUF patient, the fistula in all patients successfully resolved. Median follow up time was 81 months (range, 5-116 months). No recurrence was observed. Median bowel function score was 17.5 (range, 17-18).

CONCLUSION

The location of fistula, presence of anastomotic stricture and the association of urinary complications have significant impacts on the treatment strategy in such rare complications after TEPT for HD.

Lower Urinary Tract Symptoms in Prostate Cancer Patients Treated With Radiation Therapy: Past and Present

The incidence of prostate cancer (PCa) is increasing concomitantly with population aging. Accordingly, interest in radiation therapy (RT) and the frequency of RT are also increasing. The types of RT can be broadly divided into external beam RT (EBRT), brachytherapy (BT), and combination therapy (EBRT+BT). Lower urinary tract symptoms (LUTS) after RT for the treatment of PCa are common; however, there are few reviews on the relationship between RT and LUTS. Herein, we review the causes and incidence of LUTS, as well as the evaluation and treatment options. Because of the reported risks of RT, patients undergoing RT should be counseled regarding the challenges of treatment and informed that they may have higher failure rates than nonirradiated patients. Moreover, thorough evaluation and treatment strategies are needed to support treatment recommendations. With a review of the existing literature, this narrative article provides an overview to aid urologists in treating patients presenting with complications associated with RT for the treatment of PCa. Further research is required to provide evidence of the effectiveness and feasibility of the management approach to the care of patients with LUTS after RT for the treatment of PCa.

Repair of a rectovesical fistula following laparoscopic radical prostatectomy with Martius fat pad flap interposition: a proposal of a new technique

Rectovesical fistula (RVF) is defined as an abnormal communication between the rectum and the urinary bladder, most commonly after an iatrogenic injury during pelvic surgery. Patients with RVF may have various clinical presentations, ranging from fecaluria, pneumaturia, to urine leakage through the anus. The quality of life for patients with this pathology is adversely affected owing to the associated psychological burden. Surgery is the preferred treatment given the low success rates reported for conservative or minimally invasive approaches. Herein, we present a case of a 65-year-old man with RVF after radical prostatectomy successfully treated by a transperineal approach using a modified Martius procedure.

Surgical outcome for colorectal or urinary tract-related fistula: Usefulness of vascularized tissue transfer-a retrospective study⁎

BACKGROUND

It is challenging to manage colorectal or urinary tract-related fistula. We typically treat colorectal or urinary tract-related fistula with a vascularized tissue transfer. This study aimed to analyze the outcomes of our surgical treatments for colorectal or urinary tract-related fistula.

METHODS

This retrospective review included all patients who underwent surgical repair of a colorectal or urinary tract-related fistula at our institution from October 2004 to September 2019. Patients whose surgical outcomes could not be evaluated were excluded. The primary outcome was the overall cure rate. We also evaluated the complication rate and compared the outcomes for rectovaginal fistula with those for urorectal fistula.

RESULTS

The final analysis included 38 cases, of which 17 were rectovaginal fistula and 16 were urorectal fistula. The transperineal approach was used in 28 cases and transperineal and transabdominal combined in nine cases. A gracilis muscle flap was used in 19 cases and a gluteal fold flap in 13 cases. Although a major leak occurred in nine cases, the fistula was finally cured successfully in 31 cases. A comparison of the outcomes for rectovaginal fistula and urorectal fistula showed that complications occurred in 5/17 cases of rectovaginal fistula and 10/16 cases of urorectal fistula (p = 0.056). Fistulae were cured successfully in 13/17 cases of rectovaginal fistula and 14/16 cases of urorectal fistula (p = 0.656).

CONCLUSION

Our surgical treatment for colorectal or urinary tract-related fistula succeeded in 31 of 38 cases. Thus, vascularized tissue transfer is useful for refractory colorectal or urinary tract-related fistula.

Validating the Martini Staging System for Rectourethral Fistula: A Meta-Analysis of Postoperative Outcomes

OBJECTIVE

To validate the Martini staging system for postoperative rectourethral fistula (RUF) utilizing data from previous studies to determine whether it can accurately predict postoperative success rate.

METHODS

A systematic search of peer-reviewed studies was conducted through January, 2020. The primary inclusion criteria for the studies were studies that evaluated outcomes based on the etiology of the fistula (ie, radiotherapy/ablation [RA] vs nonradiotherapy/ablation [NRA]). Martini RUF classification was utilized for the subgroup analysis.

RESULTS

Out of 1948 papers, 7 studies with a total of 490 patients (251 in RA vs 239 NRA) were included in this study. Receiving RA increased the risk of permanent bowel diversion by 11.1 folds, eventual fistula recurrence by 9.1 folds, and post-op urinary incontinence (UI) by 2.6 folds. Similarly, compared to a Grade 0 fistula, a Grade I fistula increased the risk of permanent bowel diversion by 9.1 folds, fistula recurrence by 20 folds, and post-op UI by 2.7 folds. There were some valuable variables that were not captured by the Martini classification.

CONCLUSION

Overall, the Martini classification system is efficacious in stratifying post-op complications from RUF repair based on the grade and etiology; however, it is limited in application. There is an opportunity for the development of more comprehensive staging systems in this domain.

Surgical management of acquired rectourethral fistula: a retrospective analysis of 52 consecutive patients

BACKGROUND

Acquired rectourethral fistula (RUF) is an uncommon complication mostly resulting from surgery or radiation. Standardization of the surgical management is lacking. The aim of this study was to report our experience with surgery for RUF.

METHODS

This was a retrospective study of a prospectively maintained clinical database. The surgical strategy was tailored to complexity of RUF, presence of sepsis, history of radiation and residual urinary/fecal functionality. Outcomes measured were RUF closure and permanent fecal/urinary diversion. Impact of radiotherapy was also assessed.

RESULTS

Between November 2002 and January 2019, 52 patients were identified (100% males). Median follow-up was 10.5 (0.5-16.8) years. Three patients had RUF closure after conservative management. The remaining 49 patients had a total of 76 procedures. The cumulative closure rate after the first, second and third attempt was 55.1%, 85.7% and 95.9%, respectively. Fistula closure together with preservation of the fecal and urinary function was achieved in 49%, 65.3% and 67.3% after the first, second and third repair, respectively. The overall success rate for transanal, transperineal, restorative transabdominal and non-restorative transabdominal procedures was 35.7%, 64.3%, 57.1% and 94.1%, respectively. A significantly higher rate of urinary/intestinal stomas was observed in the irradiated vs non-irradiated patients (84.2% vs 42.4%; p = 0.004).

CONCLUSIONS

Surgery ensured healing in 96% of the patients. Radiotherapy led to higher rate of permanent urinary/fecal diversion. Nearly all irradiated patients who had transabdominal repair end up with a definitive stoma. When transperineal repair with gracilis flap interposition was used, the rate of fistula closure approached 90%. A treatment algorithm is proposed.

Recurrent rectourethral fistula repair: A novel technique of gracilis muscle interposition

BACKGROUND

A perineal approach with gracilis muscle interposition (GMI) remains the most common in recurrent rectourethral fistulas (RUFs). The closure failures in10%-20% cases and urinary incontinence in 10%-80% cases referred to the disadvantages of the perineal approach owing to neurovascular damage. This article shows that the retraction of a survived muscle gracilis flap is one of the causes of fistula recurrence, and a simpler technique of the flap interposition is presented, requiring a less invasive perineal access.

METHODS

Three consecutive patients with RUF at the age of 5, 13 and 15 years who underwent multiple (3, 4 and 5) unsuccessful reconstructive attempts were referred to our clinic. The last procedure was performed with GMI. In all cases, these were acquired iatrogenic fistulas that occurred after operations for Hirschsprung's disease (2) or anorectal malformation (1), and subsequent dilatation of the anus. All patients had a colostomy several years ago. Reinterposition and distant anchoring of the survived graсilis flap were performed through the perineal approach, avoiding lateral and anterolateral dissection.

RESULTS

The early postoperative period was uneventful. In one patient, a stricture of the posterior urethra formed. Urethrotomy was performed in 3 months, with complete restoration of micturition. The colostomy was closed in all patients after 3-4 months. In the long term follow up within 4-8 years, no fistula recurrence was noted.

CONCLUSIONS

The suggested traction technique of GMI allowed: to minimize the perineal access size, hence minimizing the injury and the operating time; to place the anchoring suture outside of the inflammation zone, ensuring secure attachment; to provide precise flap positioning and intimate contact between the flap and the urethra.

Results of the York Mason Procedure with and without Concomitant Graciloplasty to Treat Iatrogenic Rectourethral Fistulas

BACKGROUND

Rectourethral fistulas (RUFs) are rare but devastating complications after surgery or radiation therapy to the urethra, prostate, or rectum. RUF repair is challenging, especially in irradiated patients.

OBJECTIVE

To evaluate the efficacy of the York Mason (YM) procedure with or without concomitant gracilis muscle interposition (graciloplasty) for RUF repair.

DESIGN, SETTING, AND PARTICIPANTS

Records of patients with an iatrogenic RUF who underwent the YM procedure between 2008 and 2018 in two university hospitals were reviewed. Data on etiology, diagnostic and operative procedures, urinary and fecal diversion, and postoperative follow-up were collected.

INTERVENTION

Twenty-eight patients underwent 33 YM procedures. Concomitant graciloplasty was performed in four (14%) primary repairs and two (7%) repairs for recurrent RUFs.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary endpoint was successful RUF repair, defined as absence of symptoms and no leakage on control urethrocystography. The secondary endpoint was colostomy reversal rate.

RESULTS AND LIMITATIONS

Median follow-up was 24 mo. Ten patients (36%) were irradiated previously. The ultimate success rate was 75% after a maximum of three YM procedures. Success rates were 89% and 50% in patients with nonirradiated and irradiated fistulas, respectively. In irradiated patients, the success rates of the first YM procedure with and without graciloplasty were 100% and 29%, respectively. In recurrent cases, concomitant graciloplasty did not result in better outcomes. Colostomy reversal was possible in 15 patients after successful repair. In all patients, fecal continence was intact and no anal stenosis was reported. Limitations of the study include small sample size and the retrospective design.

CONCLUSIONS

Combination of the YM procedure with graciloplasty resulted in higher success rates of RUF repair in patients with irradiated fistulas. Fecal continence was preserved, and colostomy reversal is feasible.

PATIENT SUMMARY

We analyzed the outcomes, complications, and colostomy reversal rate of the York Mason procedure for the repair of rectourethral fistulas (RUFs). We found that concomitant graciloplasty increases success rates in case of prior radiation therapy. Colostomy reversal is feasible after RUF repair.

When the bowel meets the bladder: Optimal management of colorectal pathology with urological involvement

Fistulae between the gastrointestinal and urinary systems are rare but becoming increasingly more common in current surgical practice. They are a heterogeneous group of pathological entities that are uncommon complications of both benign and malignant processes. As the incidence of complicated diverticular disease and colorectal malignancy increases, so too does the extent of fistulous connections between the gastrointestinal and urinary systems. These complex problems will be more common as a factor of an aging population with increased life expectancy. Diverticular disease is the most commonly encountered aetiology, accounting for up to 80% of cases, followed by colorectal malignancy in up to 20%. A high index of suspicion is required in order to make the diagnosis, with ever improving imaging techniques playing an important role in the diagnostic algorithm. Management strategies vary, with most surgeons now advocating for a single-stage approach to enterovesical fistulae, particularly in the elective setting. Concomitant bladder management techniques are also disputed. Traditionally, open techniques were the standard; however, increased experience and advances in surgical technology have contributed to refined and improved laparoscopic management. Unfortunately, due to the relative rarity of these entities, no randomised studies have been performed to ascertain the most appropriate management strategy. Rectourinary fistulae have dramatically increased in incidence with advances in the non-operative management of prostate cancer. With radiotherapy being a major contributing factor in the development of these complex fistulae, optimum surgical approach and exposure has changed accordingly to optimise their management. Conservative management in the form of diversion therapy is effective in temporising the situation and allowing for the diversion of faecal contents if there is associated soiling, macerated tissues or associated co-morbidities. One may plan for definitive surgical intervention at a later stage. Less contaminated cases with no fibrosis may proceed directly to definitive surgery if the appropriate expertise is available. An abdominal approach with direct repair and omentum interposition between the repaired tissues has been well described. In low lying fistulae, a transperineal approach with the patient in a prone-jack knife position provides optimum exposure and allows for the use of interposition muscle grafts. According to recent literature, it offers a high success rate in complex cases.

[Fistula surgery]

Vesicovaginal fistulas are a rare problem in the western world but are frequent occurrences in developing countries. In Germany the most frequent cause is hysterectomy. Vesicovaginal fistulas can be treated by the transvaginal or transabdominal approach depending on the characteristics of the fistula and the patient. The incidence and complexity of urorectal fistulas increase with the number of cumulative sequences of prostate cancer treatment. Overall there is no clear consensus about the optimal surgical approach route. The surgical treatment of both vesicovaginal and urorectal fistulas is associated with high permanent fistula closure rates; however, for both entities if the fistula is discovered early enough, conservative treatment with a temporary catheter drainage can be tried, depending on the underlying cause. For both conditions fistula repair in irradiated patients shows a much lower success rate. A spontaneous closure of fistulas in radiogenic fistulas is also not to be expected.

High rectourethral fistula following TURP: repair possible only after transvesical prostatectomy

We report a case of iatrogenic rectourethral fistula (RUF) in an elderly man with benign prostatic enlargement and acute urinary retention, following a transurethral resection of prostate (TURP). This patient presented a unique challenge of tackling the RUF in the presence of a large residual prostate gland and urinary tract infection. RUF was repaired only after getting the access to the fistula following transvesical prostatectomy. Follow-up imaging showed well-healed repair of RUF. Transvesical prostatectomy is a useful adjunctive procedure in repair of RUF when associated with a large prostate. This case also highlights the importance of technique selection while planning for surgery on large prostate glands. TURP is not the preferred first modality of choice for larger glands as noted in this case.

Operative results, sexual function and quality of life after gracilis muscle transposition in complex rectovaginal fistulas

AIM

Successful treatment of complex rectovaginal fistulas (RVFs) continues to be a surgical challenge. Interposition of well-perfused tissue, such as gracilis muscle, is one treatment option. The aim of this study was to investigate the operative results, sexual function and quality of life after gracilis muscle transposition (GMT) in the authors' own group of patients.

METHOD

The study included 19 women with RVF (mean age 48 years). The postoperative outcome was evaluated by a questionnaire and clinical examination.

RESULTS

The postoperative follow-up period was 7 months to 3.5 years (mean 23 months). GMT led to primary healing of RVF in 10 (53%) patients. Recurrences were observed in nine (47%) patients with RVF, in four (44%) of whom healing was achieved as a result of further interventions. Following GMT, two complications (abscess formation) requiring revision occurred. Although 42% of the patients reported certain limitations following muscle removal, GMT is a procedure that has a positive influence on the healing rate (74%), quality of life, continence and patient satisfaction.

CONCLUSION

GMT is a procedure that allows healing in the majority of patients with RVFs, and it should be considered especially in patients with recurrent fistulas, in whom a correlation between decreasing healing rates and the number of previous operations has been demonstrated.

Analysis of a 7-year national online audit of the management of open reconstructive urethral surgery in men

OBJECTIVE

To conduct an audit of the management of urethral pathology in men presenting for reconstructive urethral surgery in the UK.

METHODS

Between 1 June 2010 and 31 May 2017, data on men presenting with urethral pathologies requiring reconstruction were entered onto a secure online data platform. Surgeon-entered information was collected in 95 fields regarding the stricture aetiology, prior management, mode of presentation, type of surgery and outcomes, with a potential 283 variable responses in the 95 fields. Data were analysed to compare UK practice with that reported in the contemporary literature and with guidelines.

RESULTS

Data on 4809 men were entered by 39 centres and 50 surgeons. Field completeness was 70.7%, 74.3% and 53.7% for preoperative, operative and follow-up data, respectively. Referral for stricture reconstruction frequently followed two prior endoscopic procedures and the stricture was not always assessed anatomically before surgery. Urinary retention was a common symptom in men awaiting reconstruction. Short unifocal strictures of the anterior urethra were the commonest reason for referral, whilst lichen sclerosus and hypospadias generated a significant volume of revisional stricture surgery. Lower numbers of very complex interventions are required for the management of posterior urethral pathology. Although precise criteria for determining success are not clear, management of urethral reconstruction in the UK was found to have a low risk of Clavien-Dindo grade 3 or higher complications, and was associated with outcomes similar to those reported in contemporary series except in the management of posterior urethral fistulae.

CONCLUSIONS

Online databases can provide volume data on the management of reconstructive urethral surgery across a multiplicity of centres in one country. They can also indicate compliance with accepted standards of, and expected outcomes from, this tertiary practice.
