Sigma-rectal pouch as the urine reservoir after total cystectomy

对８例侵犯膀胱颈和后尿道的多发浸润性膀胱癌病人于膀胱、前列腺及尿道全切术后行Ｓｉｇｍａ直肠膀胱术。随访４～２６个月，结果满意。代膀胱容量大，压力低，手术比较简单，克服了传统输尿管乙状结肠吻合术的许多缺点。

Construction of a sigma-rectal pouch after total cystectomy, prostatectomy and urethrectomy was made as the urine reservoir for 8 cases of extensive bladder carcinoma invading the bladder neck and urethra. The patients have been followed up for 4～26 months with satisfactory result.The pouch was fixed at the promontory area guaranteering a straight ureter path,with high filling volume and low pressure. The operative procedure was less time consuming and has heed a sound alternative to continent urinary diversion.
