Comparison of clinical efficacy of orthotopic ileal neobladder versus orthotopic sigmoid neobladder / 中华泌尿外科杂志

ABSTRACT

Objective To compare the clinical efficacy of orthotopic ileal neobladder versus ortho- topic sigmoid neobladder.Methods The data of 96 patients who had undergone orthotopic ileal neoblad- der and 68 patients who had undergone orthotopic sigmoid neobladder were retrospectively analyzed.The perioperative condition,urinary continence,urodynamics,and pouch-related complications were compared between the 2 groups.Results Of all the 164 patients,12(7.3%)were lost to follow-up.The mean fol- low-up was 46(2-86)months in orthotopic ileal neobladder group,and 42(4-78)months in orthotopic sigmoid neobladder group.There was no significant difference in intraoperative blood loss and postoperative urinary continence between the 2 approaches(P＞0.05).However,compared with sigmoid neobladder group,ileal neobladder group had longer operative time and postoperative recovery time,and got a bigger pouch(P＜0.05).The early and late pouch-related complication rates of ileal neohladder group were 16. 7% and 29.2%,which were higher than those of sigmoid neobladder group.During the follow-up,tumor recurred in 3 cases of ileal neobladder group,but none in sigmoid neobladder group.Conclusions Ortho- topic ileal neobladder and sigmoid neobladder are similar in operative difficulties,and both can achieve satis- factory clinical results.Compared with ileal neobladder,sigmoid neobladder has shorter operative time, quicker recovery and lower rate of pouch-related complications,thus is a preferred procedure.
