【摘要】 目的 评价改良Sigma直肠膀胱术式可控性尿流改道的临床疗效。方法 在2002年1月～2004年6月对5例膀胱癌患者采用改良Sigma直肠膀胱术式。折叠乙状结肠约25cm后全层切开，再缝合成低压袋，顶端固定在骶岬处，两输尿管末端合并，从低压袋上方引入，与切除了一小片段的肠黏膜匙形吻合再植。结果 全组所有患者尿控率100%，无尿失禁、未发生明显酸碱平衡紊乱、肾功能损害及上尿路感染、上尿路结石、吻合口狭窄等并发症。结论 改良Sigma直肠膀胱术并发症低、尿控效果好，术后生活质量较高，是一种快速、安全并简单易行的尿流改道方法。

    【Abstract】 Objective To introduce a modified technique of Sigma rectum pouch procedure as a continent urine reservoir after radical cystectomy.Methods 5 cases of bladder cancer underwent the modified Sigma rectum pouch operation from Jan.2001 to Jun.2004.A segment of sigmoid colon was folded and a longitudinal incision about 25cm was made on the sigmoid wall and the incision was sutured so as to form a low pressure pouch.The vertex of the new pouch was fixed to the sacrum.The ends of the 2 ureterers were anastomosed together and was then drawn into the top of the pouch for 2 cm and finally the ureterosigmoidostomy was accomplished.Results Continence rate was 100%.All the patients were able to distinguish between stool and urine.Symptomatic renal infection and hyperchloremic acidosis occurred seldomly.No patient developed upper tract stone or ureterointestinal anastomotic stricture.Conclusion The modified sigma rectum pouch procedure is a quick,safe and easy to perform urinary diversion which serves as a satisfying alternative for patients in terms of quality of life.Follow-up shows a low complication rate with good results in terms of continence. ......
