目的：探讨低压回肠代膀胱术的技术改进及远期疗效。方法：对１６ 例全膀胱切除的膀胱癌病人，施行回肠袋近端肠管人工套迭加隧道式输尿管肠吻合术，同时用２ ％ 碘酊处理回肠袋粘膜以减少肠粘膜的分泌与吸收。结果：手术时间平均５ 小时５０ 分钟。术后随访１１ ～７２ 个月，全部病人白天均能自控排尿，无输尿管返流，无代谢性酸中毒，无手术死亡及再次手术。结论：本术式具有成功率高，并发症少，病人术后生活质量高等优点 Objective: To discuss the technical improvement and long-term curative effect of low-pressure ileal neobladder. Methods: Sixteen patients undergoing total cystectomy of bladder cancer were treated with transvaginal ureteral anastomosis via the proximal intestine of ileal pouch. Meanwhile, the ileal mucosa was treated with 2% iodine tincture to reduce the secretion and absorption of intestinal mucosa. Results: The operation time averaged 5 hours and 50 minutes. Patients were followed up for 11 to 72 months. All patients were able to control urination during the day, without ureteral reflux, without metabolic acidosis, without surgical death and reoperation. Conclusion: This technique has the advantages of high success rate, less complications and higher postoperative quality of life
