膀胱癌根治术后T型回肠新膀胱术的临床应用

目的探讨膀胱癌根治术后T型回肠新膀胱术的手术方法及临床应用价值。方法对25例膀胱癌患者施行T型回肠新膀胱术：截取一段54 cm左右的回肠,利用远端的44 cm肠管做成储尿囊,而近端的10 cm肠管作为新膀胱的输入袢,并通过将输入袢远端的5 cm肠管包埋于构成储尿囊两肠管之间的浆膜隧道内而形成抗返流机制。结果25例手术经过顺利,术后3周拔除尿管后均能自控排尿,尿量为50～200 ml。术后3个月复查尿常规无异常,肾功能及电解质无异常。尿动力学检查,新膀胱最大容量为（327.3±62.7）ml,最大尿流率为（16.2±7.9）ml/s,充盈期膀胱内压力为0～8 cmH2O,排尿期膀胱内压力为8～16cmH2O,剩余尿为0～40 ml。静脉肾盂造影或B超检查,结果表明无肾积水、无输尿管扩张。膀胱造影未见输尿管返流。结论原位T型回肠新膀胱术具有良好的可操作性、较好的尿控及排尿能力,是一种良好的尿流改道术,值得临床推广应用。

The clinical application of T pouch ileal neobladder operation after the radical correction of carcinoma of bladder

Objective To explore the operation method and its clinical application value of T pouch ileal neobladder operation after the radical correction of carcinoma of bladder.Methods25 patients with carcinoma of bladder were performed T pouch ileal neobladder operation.54 cm terminal portion of the ileum was used to construct the T-pouch.The distal 44 cm ileum was used to form the reservoir,while the proximal 10 cm ileum was used to form the afferent antireflux mechanism by anchoring the distal 5 cm afferent ileal...
