RESUMEN
<p><b>OBJECTIVE</b>To compare the postoperative recovery among patients undergoing orthotopic bladder substitution with sigmoid or ileal grafts.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>A neobladder constructed from ileal grafts achieves better postoperative recovery results compared to a neobladder constructed from sigmoid grafts.</p>
