Abstract: Objective To compare the postoperative recovery among patients undergoing orthotopic bladder substitution with
sigmoid or ileal grafts. Methods The clinical data and postoperative recovery (postoperative complications, continence
recovery time and postoperative hospital stay) of 84 patients receiving orthotopic bladder substitution with sigmoid or ileal
grafts after radical cystectomy for bladder cancer were analyzed. Results Of the 84 cases, 70 had continent urinary reservoirs
constructed, among whom 58 (aged 48-89 years) received an ileal neobladder (IN) and 12 (aged 28-80 years) received a sigmoid
neobladder (SN). The postoperative complications rate, continence recovery time and postoperative hospital stay in IN group
was 29.3% (17/58), 91.4%, and 23.5 days, as compared to 58.3%(7/12) (P=0.04), 66.7% (P=0.03), and 25 days (P=0.04) in patients
in SN group, respectively. Conclusion A neobladder constructed from ileal grafts achieves better postoperative recovery
results compared to a neobladder constructed from sigmoid grafts.
