尿道腔内长期置管压迫防治复杂性尿道狭窄复发(附21例报告)

The Effcet of long-term Intraurethral Intubation on Protecting Complex Urethral Stricture from Recurrence (Report of 21 cases)

为防治复杂性尿道狭窄术后复发,作者根据“弹力加压包扎治疗烧伤瘢痕增生”的原理,设计了尿道腔内置多孔硅胶支架管持续压迫防治复杂性尿道狭窄复发的方法。从1990年1月～1997年10月治疗21例,置管时间2～6个月,全部恢复正常排尿,2例在置管期间需电切不光滑瘢痕段后尿道。介绍了支架管的制做、长期置管指征、方法及术后处理。对其机理、利弊进行了探讨。认为本疗法简便、有效。

In order to prevent and treat the post-operational stenostic recurrence of complex urethral stricture cases, an unique porous silicone tube has been used intraurethrally to produce constant compressing force against scar tissue, which is similar with that of pressure bandage against burning cicatricial hypertrophy. From Jan. 1990 to Oct. 1997,the method has been applied in 21 cases, including 7cases of anterior urethral stenosis and 14 cases of posterior ones. During the intubation period ranging from 2 to 6 months, 2 cas- es needed transurethral scar resection. All patients regained normal micturition eventually. The tube preparation and catheterization methods are discussed, as well as the indication and nursing gist. The method is thought to be simple and effective.
