Reducing the rate of uretero‐enteric strictures after robot‐assisted cystectomy: a green light for immunofluorescence?

Benign postoperative ureteric strictures are thought to be largely attributable to inadequate vascularization of the distal ureter on account of its segmental blood supply. Despite meticulous dissection technique and avoidance of traction or anastamotic tension, many series still report a stricture rate in the order of 10% in both open and minimally invasive surgery. Conventionally, the left ureter is associated with a higher risk because of its more extensive mobilization and longer trajectory behind the recto-sigmoid.
