PD59-03 INTRACORPOREAL VERSUS EXTRACORPOREAL NEOBLADDER AFTER ROBOT-ASSISTED RADICAL CYSTECTOMY: RESULTS FROM THE INTERNATIONAL ROBOTIC CYSTECTOMY CONSORTIUM

Abstract Objectives To compare perioperative and oncologic outcomes of intracorporeal (ICNB) and extracorporeal neobladder (ECNB) following robot assisted radical cystectomy (RARC) from a multi-institutional, prospectively maintained database, the International Robotic Cystectomy Consortium (IRCC). Methods A retrospective review of IRCC database between 2003 and 2020 (3742 patients from 33 institutions across 14 countries) was performed (I-97906). The Cochran-Armitage trend test was used to assess utilization of ICNB over time. Multivariate logistic regression models were fit to evaluate variables associated with receiving ICNB, overall complications, high-grade complications, and readmissions after RARC. Kaplan Meier curves were used to depict recurrence-free (RFS), disease-specific (DSS), and overall survival (OS). Results 411 patients received neobladder, 64% underwent ICNB. ICNB utilization increased significantly over time (p Conclusion Utilization of ICNB increased significantly over time. Patients who underwent RARC and ICNB had shorter hospital stays and fewer 30-d reoperations but were readmitted more frequently compared to those who underwent ECNB.
