Clinical Study on Ureterostenosis with Incision of Ho: YAG Laser

目的 探讨输尿管镜下钬激光（Ho：YAG激光）内切开术治疗输尿管狭窄的方法及疗效。方法 2004-05-2005-10，采用经输尿管镜钬激光内切开治疗45例输尿管狭窄，术中留置双J管，术后2、3个月拔除双J管，拔管后4、12周、6个月进行超声、排泄性尿路造影检查。结果 术后45例共随访了40例，随访率88．9％，随访3-24个月；35例治愈（治愈率87．5％），3例治疗好转，2例无效。结论 输尿管镜下钬激光内切开加留置双J管治疗输尿管狭窄，具有创伤小、疗效好、视野清、并发症少。

Objective To discuss the method and curative effect of ureterostenosis with incision of Ho： YAG laser under ureteroscope. Methods 50 of 45 cases ureterostenosis were underwent incision with Ho： YAG laser from May 2004 to October 2005 and retained Double J tube for 2- 3 months. The ultrasound and excretion urography after 4, 12 and 26 week extubafion. Results The follow- up rate was 88.9% （40/45） in 3-24 months. Thecurative rate was 87.5% with3 cases better and 2 cases noefl＇eet. Conchusion This methed might have less injury, good curative effect, clear vision and less complication.
