下腹壁人工外尿道成形在回肠膀胱术中的应用

目的 为回肠膀胱术患者重建人工外尿道，改善尿液收集方法。方法 1995年8月至2005年7月，为17例膀胱癌患者，在施行膀胱全切除、回肠膀胱术后，在右下腹壁设计两个反向梯形皮瓣对合为管状作为被覆，以回肠膀胱远端段肠瓣作为衬里，共同建造腹壁管状人工外尿道。17例人工外尿道中，16例与回肠膀胱术同时形成，1例在回肠膀胱腹壁膀胱造口1年后成形。在管状外尿道套接由阴茎套及普通尿袋改装的收集器进行尿液收集。结果 17例下腹壁人工外尿道均一次手术获得成形，供瓣区直接闭合，伤口一期愈合；尿流呈点滴或线状，收集容易，污染少。结论 该腹壁人工外尿道成形术操作简单，安全；尿液收集方便，卫生，费用低廉，适合回肠膀胱患者采用。
