Is experience with extracorporeal urinary diversion following robotic assisted radical cystectomy necessary before transitioning to intracorporeal urinary diversion?

Efforts to minimise the high morbidity following open radical cystectomy have led to the development of robotic assisted radical cystectomy (RARC) (1). Since first reported in 2003, the uptake of RARC has increased in recent years despite the lack of solid evidence to suggest a perioperative benefit (2,3).
