Conservative treatment for urinary fistula following ileal conduit urinary diversion: a simple method.

ABSTRACT: BACKGROUND:The presence of urinary fistula after ileal conduit urinary diversion is a challenging complication, and this study investigated the role of the intra-conduit negative pressure system (NPS) in the presence of urinary fistula following ileal conduit (IC) urinary diversion as a conservative treatment. METHODS:Using the intra-conduit NPS, a minor drainage tube was placed within a silicon tube to suck urine from the conduit with consistent negative pressure. Patients with urinary fistula following IC from August 2012 to July 2017 were recorded, and the clinical characteristics and outcome were retrospectively analyzed. RESULTS:The intra-conduit NPS was used as a primarily conservative treatment for 13 patients who suffered from urinary fistula and presented with a large amount of abdominal/pelvic drainage without other significant morbidities. The median age was 60?years old (42-74?years), and 7patients were male. The median duration between the IC operation and the presence of urinary fistula was 15?days (2-28?days), and elevated creatinine levels were detected in the abdominal/pelvic drainage with a median level of 2114??mol/L (636-388??mol/L). A significant decrease in abdominal/pelvic drainage was identified in 12 patients. The median time that the NPS was used was 9?days (7-11?days). The other patient did not show any improvements after 2?days of observation and then underwent open surgery. With ureteral stenting, 2 abdominal drainage tubes and the intra-conduit NPS were placed during operation, no urine leakage was observed in the abdominal/pelvic field, and the patient was cured in 9?days. With a median follow-up of 22?months, no fistula recurrence or hydronephrosis was detected. CONCLUSION:The intra-conduit negative pressure system is a feasible and promising way to cure urinary fistula following ileal conduit urinary diversion. Because this procedure is a mini-invasive and simple approach, it might represent an alternative in selected patients.

Project description:BackgroundParastomal hernia after ileal conduit urinary diversion is an underestimated and undertreated clinical entity, which heavily impairs patients' quality of life due to symptoms of pain, leakage, application or skin problems. As for all gastrointestinal stomata the best surgical repair technique has yet to be determined. Thereby, surgery for ileal conduit parastomal hernias poses some specific perioperative challenges. This review aims to give an overview of current evidence on the surgical treatment of parastomal hernia after cystectomy and ileal conduit urinary diversion, and on the use of prophylactic mesh at index surgery in its prevention.MethodsA systematic review was performed according to PRISMA-guidelines. The electronic databases Embase, PubMed, Cochrane Library, and Web of Science were searched. Studies were included if they presented postoperative outcomes of patients undergoing surgical treatment of parastomal hernia at the ileal conduit site, irrespective of the technique used. A search was performed to identify additional studies on prophylactic mesh in the prevention of ileal conduit parastomal hernia, that were not identified by the initial search.ResultsEight retrospective case-series were included for analysis, reporting different surgical techniques. If reported, highest complication rate was 45%. Recurrence rates varied highly, ranging from 0 to 80%. Notably, lower recurrence rates were reported in studies with shorter follow-up. Overall, available data suggest significant morbidity after the surgical treatment of ileal conduit parastomal hernias. Data from five conference abstracts on the matter were retrieved, and systematically reported. Regarding prophylactic mesh in the prevention of ileal conduit parastomal hernia, 5 communications were identified. All of them used keyhole mesh in a retromuscular position, and reported on favorable results in the mesh group without an increase in mesh-related complications.ConclusionData on the surgical treatment of ileal conduit parastomal hernias and the use of prophylactic mesh in its prevention is scarce. Given the specific perioperative challenges and the paucity of reported results, more high-quality evidence is needed to determine the optimal treatment of this specific surgical problem. Initial results on the use of prophylactic mesh in the prevention of ileal conduit parastomal hernias seem promising.

Project description:PurposeSurveillance following urinary diversion should be tailored to capture complications downstream from the initial reconstruction. Most analyses of the morbidity associated with urinary diversion are restricted to the index admission or the immediate postoperative period. We characterize the long-term medical and surgical complications and burden of health care use after urinary diversion.Materials and methodsUsing the 5% Medicare sample from 1998 to 2005 we identified individuals who underwent cutaneous and orthotopic continent urinary diversion, ileal conduit or other types of diversion including enterocystoplasty from physician claims for the index admission. We restricted our sample to subjects with claims 1 year before surgery and at least 2 years after the diversion. We included benign and malignant primary diagnoses, and evaluated the incidence of medical and surgical complications 2 and 5 years after surgery. We stratified complications by diversion type and compared long-term complications after urinary diversion surgery.ResultsOf the 1,565 subjects identified 80% underwent ileal conduit urinary diversion, 7% underwent cutaneous or orthotopic continent diversion and 13% underwent other types of reconstruction. Urinary stone formation, wound complications and fistula complications were more common following continent diversion 5 years after surgery, while ureteral obstruction and renal failure/impairment were more common after ileal conduit diversion. Overall we estimated that more than 16% of patients experienced renal failure or impairment after urinary diversion.ConclusionsComplications are common after urinary diversion and continue to occur through 5 years postoperatively. Urolithiasis and delayed wound complications appear to occur more commonly after continent diversion than after other urinary diversions. A large proportion of patients experience renal deterioration after diversion. These results highlight the need to survey patients for the diversion related complications of cystectomy as rigorously as we monitor for cancer recurrence.

Project description:BackgroundRadical cystectomy (RC) with urinary diversion is the recommended treatment for selected cases of non-metastatic high-risk non-muscle-invasive and muscle-invasive bladder cancer. It remains unknown whether robot-assisted laparoscopic cystectomy (RARC) offers any advantage in terms of safety compared to open cystectomy (ORC) in an Enhanced Recovery After Surgery (ERAS) setup. Blinded randomised controlled trials (RCTs) between RARC versus ORC have never been conducted in cystectomy patients. We will investigate the feasibility of conducting a double-blinded RCT comparing ORC with RARC with intra-corporal ileal conduit (iRARC) in an ERAS setup.MethodsThis is a single-centre, double-blinded, randomised (1:1) clinical feasibility study for patients with non-metastatic high-risk non-muscle-invasive or muscle-invasive bladder cancer scheduled for cystectomy. All participants are recruited from Rigshospitalet, Denmark. The planned sample size is 50 participants to investigate whether blinding of the surgical technique is feasible. Participants and postoperative caring physicians and nurses are blinded using a pre-study designed abdominal dressing and blinding of the patient's electronic health record. Study endpoints are assessed 90 days postoperatively. The primary aim is to study the frequency and pattern of unplanned unblinding after surgery and the number of participants who cannot guess the surgical technique at the day of discharge. Eleven secondary endpoints are assessed: length of stay, days alive and out of hospital, in-hospital complication rate, 30-day complication rate, 90-day complication rate, readmission rate, quality of life, blood loss, pain, rate of moderate/severe post-anaesthesia care unit (PACU) complications, and delirium. Participants are managed in an ERAS setup in both arms of the trial.DiscussionWe report on the design and objectives of a novel experimental feasibility study investigating whether blinding of the surgical technique in cystectomy patients is possible. This information is essential for the design of future blinded trials comparing ORC to RARC. There is a continued need to compare RARC and ORC in terms of both efficacy, safety, and oncological outcomes. Estimated end of study is March 2021.Trial registrationClinicalTrials.gov ID: NCT03977831. Registered on the 6th of June 2019.

Project description:The ureterointestinal anastomosis stricture (UAS) is a common complication of urinary diversion after radical cystectomy. For decades, open anastomotic revision remained the gold standard for the treatment of UAS. However, with the advancement in endoscopic technology, mini-invasive therapeutic approaches have been used in its management. Here, we report our experience with and long-term results of combined simultaneous antegrade and retrograde endoscopy (SARE) in the treatment of non-malignant UASs after urinary diversion in a consecutive series of patients.From March 2012 to January 2015, there were 32 consecutive patients with 32 non-malignant UASs following radical cystectomy and urinary diversion. Twenty-nine patients were treated with SARE technique and comprised the study group. Using simultaneous antegrade flexible ureteroscope combined with retrograde semi-rigid ureteroscope or nephroscope, partial or complete strictures were managed with laser incision and balloon dilation under direct visualization. A 7/12 Fr graded endopyelotomy stent was left for 3-6 months after the procedure. Success was defined as symptomatic improvement and radiographic resolution of obstruction.With a median followup of 22 months (6-36), the overall success rate for SARE was 69.0%. Twenty patients with partial stricture had a success rate of 85%, and 9 patients with complete stricture had a success rate of 33.3%. Renal function, hydronephrosis grade, stricture type, and stricture length were significant influences on the outcome (P < 0.05). No complication was observed.The SARE is a safe and effective treatment for UAS, and may be the only endoscopic treatment approach for complete UAS. While success rate for complete strictures is low compared to open revision, it should be considered as an initial approach given its low overall morbidity. For partial strictures, prudent patient selection results in higher success rates that are nearly comparable to open revision.
