Ileal Conduit versus Cutaneous Ureterostomy after Open Radical Cystectomy: Comparison of 90-Day Morbidity and Tube Dependence at Intermediate Term Follow-Up.

Background : This study aims to compare perioperative morbidity and drainage tube dependence following open radical cystectomy (ORC) with ileal conduit (IC) or cutaneous ureterostomy (CU) for bladder cancer. Methods : A single-center, retrospective cohort study of patients undergoing ORC with IC or CU urinary diversion between 2020 and 2023 was carried out. The 90-day perioperative morbidity, as per Clavien-Dindo (C.D.) complication rates (Minor C.D. I-II, Major C.D. III-V), and urinary drainage tube dependence (ureteral stent or nephrostomy tube) after tube-free trial were assessed. Results : The study included 56 patients (IC: 26, CU: 30) with a 14-month median follow-up. At 90 days after IC or CU, the frequencies of any, minor, and major C.D. complications were similar (any-69% vs. 77%; minor-61% vs. 73%; major-46% vs. 30%, respectively, p > 0.2). Tube-free trial was performed in 86% of patients with similar rates of tube replacement (19% IC vs. 32% CU, p = 0.34) and tube-free survival at 12 months was assessed (76% IC vs. 70% CU, p = 0.31). Conclusions : Compared to the ORC+IC, ORC+CU has similar rates of both 90-day perioperative complications and 12-month tube-free dependence. CU should be offered to select patients as an alternative to IC urinary diversion after RC.
