N2 - Objective: 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-79606). 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, disease-specific, and overall survival. Results: Four hundred eleven patients received neobladder, 64% underwent ICNB. ICNB utilization increased significantly over time (P <.01). Patients who received ICNB were readmitted and received neoadjuvant chemotherapy more frequently (36% vs 24%, P = .03, 35% vs 8%, P <.01, respectively). ICNB was associated with older age (OR 1.04, 95% CI 1.01-1.07, P = .001), receipt of neoadjuvant chemotherapy (OR 4.63, 95% CI 2.34-9.18, P <.01), and more recent RARC era (2016-2020) (OR 12.6, 95% CI 5.6-28.4, P <.01). On multivariate analysis, ICNB (OR 5.43, 95% CI 2.34-12.58, P <.01), positive surgical margin (OR 4.88, 95% CI 1.29-18.42, P = .019), longer operative times (OR 1.26, 95% CI 1.00-1.58, P = .048), and institutional annual RARC volume (OR 1.09, 95% CI 1.05-1.12, P <.01) were associated with readmissions. 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.
