Long-term results of cystectomy involving formation of ureterosigmoid anastomosis and ureterocutaneostomy were studied in 51 cases of cancer of the urinary bladder. Half the patients with T2 tumors and 23%--with T3 tumors survived for 3 years and longer. Tumor process generalization caused death long after operation in 64.2%, while renal failure--in 32.1%. During 1-2 years of follow-up, such pathological changes in uretero-intestinal anastomoses as abnormally large diameter of ostium ureteris and cicatricial stricture were identified in 14 cases and stricture of uretero-cutaneous stoma--in 2 cases. The best results in formation of ureterosigmoid anastomosis were obtained by application of transsigmoid procedures which assured reflux prevention, retention change-free ureters alone being eligible for use in anastomosis.
对51例膀胱癌患者行膀胱切除术并进行输尿管乙状结肠吻合术和输尿管皮肤造口术的长期结果进行了研究。T2期肿瘤患者中有一半以及T3期肿瘤患者中有23%存活了3年及更长时间。肿瘤进展扩散导致64.2%的患者在术后很长时间死亡，而肾衰竭导致32.1%的患者死亡。在随访的1至2年中，14例患者的输尿管肠吻合口出现了诸如输尿管口直径异常增大和瘢痕性狭窄等病理变化，2例患者出现了输尿管皮肤造口狭窄。通过应用经乙状结肠手术进行输尿管乙状结肠吻合术取得了最佳效果，该手术可确保预防反流，仅无改变的保留输尿管才有资格用于吻合。
