COMPARISON OF STUDER ILEAL NEOBLADDER AND ILEAL CONDUIT URINARY-DIVERSION WITH RESPECT TO PERIOPERATIVE OUTCOME AND LATE COMPLICATIONS

Purpose: We compare the perioperative and long-term morbidity of a coh ort of patients who had undergone Studer ileal neobladder urinary dive rsion with that of a similar cohort who had undergone ileal conduit ur inary diversion during the same interval and by the same surgeons. Mat erials and Methods: Between 1990 and 1996 we performed Studer ileal ne obladder urinary diversion in 62 men and 4 women, and ileal conduit ur inary diversion in 66 men. Mean age of the neobladder and conduit pati ents was 62 and 69 years, and mean followup was 17 and 20 months, resp ectively. Results: Of 66 neobladder cases (18%) 12 had a total of 16 p erioperative complications and a 5% reoperation rate, whereas 12 of 66 conduit cases (18%) had a total of 17 perioperative complications and a 6% reoperation rate. Mean hospital stay was 13 days for each group. Of the neobladder cases 14 (21%) had 14 late complications and an 11% reoperation rate, whereas 8 conduit cases (12%) had 9 late complicati ons and an 8% reoperation rate. Conclusions: The Studer ileal neobladd er urinary diversion is a safe procedure with perioperative and long-t erm morbidity comparable to ileal conduit diversion at our institution .
