Abstract

Background: Head-to-head comparisons between ileal conduit (IC) and orthotopic neobladder (ONB) in terms of peri-and postoperative outcomes and complications, in the specific setting of robot-assisted radical cystectomy (RARC), are not available.Objective: To address the impact of the type of urinary diversion (UD, IC vs ONB) on RARC morbidity, as well as operative time (OT), length of stay (LOS), and readmissions.Design, setting, and participants: Urothelial bladder cancer patients treated with RARC at nine high-volume European institutions between 2008 and 2020 were identified. Intervention: RARC with either IC or ONB.Outcome measurements and statistical analysis: Intra-and postoperative complica-tions were collected and reported according to the Intraoperative Complications Assessment and Reporting with Universal Standards recommendations and European Association of Urology guidelines, respectively. Multivariable logistic regression models tested the impact of UD on outcomes, after adjustment for clus-tering at single hospital level.Results and limitations: Overall, 555 nonmetastatic RARC patients were identified.
