Intracorporeal urinary diversion following robot-assisted radical cystectomy is associated with reductions in perioperative blood transfusion (7% vs 16%), and 90-day rates of hospital readmission (12% vs 19%) and postoperative mortality (1.6% vs 4.9%) compared with extracorporeal diversion. Surgical data collected at 18 international centres between 2003 and 2011, comparing 167 intracorporeal and 768 extracorporeal procedures, also showed that operative time, hospital stay and rates of postoperative complications were comparable in the two groups.
