Selection and perioperative management of patients undergoing an orthotopic ileal bladder substitution

Abstract

Orthotopic ileal bladder substitution (Studer pouch) has gained much popularity during the last decade, offering the best form of urinary diversion in appropriately selected patients. The superiority of this procedure is well known, with a low complication and high success rate. In the present study the most important details in patient selection, surgical technique, perioperative management with short- and long-term postoperative follow-up are described. Adequate preoperative assessment results in a proper indication for surgery and appropriate patient selection. The cystectomy should be performed with atraumatic dissection and preservation of the urethral autonomic innervation and sphincter apparatus. The bladder substitute is constructed from a terminal ileal segment of proper length formed into a spherical shape. Implantation of the ureters into the reservoir should not be performed using an anti- reflux technique to avoid a high stricture rate. Anastomosis of the bladder substitute to the urethra must be flat and wide open, avoiding a funnel- shaped outlet. In the immediate postoperative period, careful monitoring is necessary to minimize metabolic complications of acidosis and salt loss. To achieve successful voiding rehabilitation, with complete reservoir emptying, good functional reservoir capacity and satisfactory continence, it is necessary to educate the patients as to the physiological functioning of the bladder substitute. Careful lifelong follow up is essential for the successful outcome. Respecting strict patient selection criteria and proper surgical technique are of utmost importance for the successful outcome of the procedure, but only if combined with regular follow-up.
