Procedures were categorized based on surgical technique and date of the relevant hospital’s acquisition of a surgical robot. Of the over cohort, surgical technique was: 38,904 (73%) open, 6875 (13%) laparoscopic, and 7627 (14%) robotic-assisted surgery. The change in percentage of surgical type (RN vs. PN) and procedure type (Open vs. Lap) was performed based on whether it occurred before or after the hospital acquired a surgical robot. RESULTS: Before a hospital acquired a surgical robot, on average 81.6% of all renal surgery performed were RN, and this decreased to 70.1% after robot purchase; PN utilization increased from 19.2% to 31.2% after introduction of the robotic system. Over the same time period, open renal surgery decreased from 85% to 58.9% and laparoscopic decreased from 15.0% to 13.5% (see table); with a subsequent increase in robotic surgery, all values significant p¼
