Abstract

Purpose

Ileal conduit is commonly employed as a urinary diversion procedure for patients with bladder cancer after radical cystectomy. Studies have reported that ureteroileal anastomotic stricture remains a serious complication following ileal conduit diversion. The aim of this study was to introduce a novel modified technique for ureteroileal anastomosis and evaluate postoperative complications, with a specific focus on the incidence of ureteroileal anastomotic stricture.

Methods

A prospective single-center, single-surgeon cohort study was conducted on 29 consecutive patients who underwent laparoscopic radical cystectomy with ileal conduit urinary diversion between February 2017 and April 2021. A descriptive statistical analysis was performed where intraoperative variables and postoperative complications were assessed.

Results

All 29 operations were successful with an average operation time of 372.9 ± 94.3 min. The mean follow-up time was 39.62 ± 15.93 months. No cases of UIAS occurred. Three patients (10.3%) had febrile urinary tract infection, three patients (10.3%) had a transient small bowel obstruction, one patient (3.4%) had ileal anastomotic fistula, one patient (3.4%) had ileal conduit leakage, and one patient (3.4%) died 2 months after surgery due to multiple respiratory diseases. One patient (3.4%) had a mild left ureteral obstruction and CT indicated the obstruction site was in front of the iliac vessels where the left ureter had transposed to the right.

Conclusion

The modified ureteroileal anastomosis can reduce the incidence of UIAS.
