Contemporary analysis of ureteroenteric strictures after open and robot-assisted radical cystectomy: A population-based study.

484Background: Robot-assisted radical cystectomy (RARC) has been shown to have comparable oncologic efficacy compared to open radical cystectomy (ORC). We sought to compare the rates of benign strictures after RARC and ORC using a population-based data. Methods: From Surveillance, Epidemiology, and End Results (SEER)-Medicare, we identified 332 RARC and 1449 ORC performed during 2009 and 2014, using International Classification of Diseases-9th edition and Current Procedural Terminology 4th edition to compare the development of ureteroenteric strictures at 6 months, 1 year and 2 years following radical cystectomy. We defined ureteroenteric stricture as the need for procedural intervention, consistent with prior studies. Additionally, we compared the incidence of stricture diagnosis. Multivariable proportional hazards regression was performed to determine factors associated with stricture development. Results: The incidence of ureteroenteric stricture at 6 months and 12 was higher for RARC vs. ORC at 12.1% ...
