Perioperative Outcomes and Continence Following Robotic-Assisted Radical Cystectomy with Mainz Pouch II Urinary Diversion in Patients with Bladder Cancer

Abstract

Abstract PURPOSE To present the widely unknown perioperative outcomes and continence statuses of bladder cancer patients following robotic-assisted radical cystectomy (RARC) with Mainz Pouch II urinary diversion (UD). MATERIALS AND METHODS From November 2020 to December 2022, 37 bladder cancer patients who underwent RARC with Mainz pouch II UD were retrospectively assessed (ChiCTR2300070279). Patient demographics, perioperative data, continence, and complications (early ≤ 30 days and late > 30 days) were all documented. A numeric rating scale assessed patient satisfaction with urinary continence 30 days after surgery. RESULTS Of the 37 patients evaluated over a median (range) follow-up period of 11.8 (1.6–24.5) months. The median (range) age was 65 (40–81) years. The median (range) time to urinary continence after surgery was 2.3 (1.5-6) months. Of the 37 patients, 31 (83.6%) were continent both during the day and at night, 34 (91.9%) were continent during the day, 32 (86.5%) were continent at night, 35 (94.6%) were satisfied with their urinary continence status, and 21 (56.8%) were very satisfied. The mean (range) voiding frequency was 6 (4–10) during the day and 3 (2-5.5) at night. Five (13.5%) patients experienced late complications. CONCLUSIONS Mainz pouch II UD following RARC in bladder cancer patients results in a satisfactory continence rate, and the intracorporeal approach to Mainz pouch II UD works better for female patients due to its reduced invasiveness.
