Published: August 2018

Anastomotic stricture is a well-known complication of the urinary diversion that accompanies radical cystectomy. Management options range from endoscopic procedures to open surgeries, with a subset of the latter employing bowel as the interposing segment. In this report, we describe a rare patient, who successfully underwent a "Reverse 7" procedure, bypassing strictures at both anastomotic junctions between ureters and neobladder.

Article Synopsis
  • This study presents a series of 16 cases using single-port robotic surgery to repair ureteroenteric anastomosis stricture (UES), marking the first documented success with this technique.
  • A retrospective review was conducted on patients who underwent this procedure after radical cystectomy from September 2020 to July 2024, assessing demographics and surgical outcomes.
  • Results showed that surgeries were accomplished with minimal complications, an average operation time of 265 minutes, and a low average hospital stay of 4.9 days, indicating that this technique is both safe and effective, though further research is recommended.

Objective: To evaluate risk factors contributing to side-specific benign ureteroenteric strictures following radical cystectomy with an ileal conduit.

Materials And Methods: Data obtained from patients with bladder cancer who underwent radical cystectomy with ileal conduit surgery between 2015 and 2018 were retrospectively analysed. Imaging prior to surgery was analysed, regarding calcifications in the aorta, sarcopenia and postoperatively for length of remaining left ureter.

Aim Of The Study: The aim of our study is to evaluate the difference in stricture rate between matched groups of Bricker and Wallace techniques for ureteroileal anastomosis.

Patients And Methods: A retrospective analysis of patients undergoing urinary diversion (UD) with Bricker and Wallace ureteroileal anastomosis at two university hospitals. Two groups of Bricker and Wallace patients were matched in a 1:1 ratio based on the age, sex, body mass index (BMI), Charlson comorbidity index (CCI), preoperative hydronephrosis, prior radiation therapy or abdominal surgery, pathologic T and N stages and 30-days-Clavien grade complications≥III.

Introduction: To evaluate the prevalence, predictors, management, and trends for ureteroenteric strictures (UES) after robot-assisted radical cystectomy (RARC).

Methods: Retrospective review of our RARC database was performed (2005-2022). UES was described in terms of timing, laterality, and management.

Uretero-enteric anastomotic strictures (UES) after robot-assisted radical cystectomy (RARC) represent the main cause of post-operative renal dysfunction. The gold standard for treatment of UES is open uretero-ileal reimplantation (UIR), which is often a challenging and complex procedure associated with significant morbidity. We report a challenging case of long severe bilateral UES (5 cm on the left side, 3 cm on the right side) after RARC in a 55 years old male patient who was previously treated in another institution and who came to our attention with kidney dysfunction and bilateral ureteral stents from the previous two years.
