【摘要】 目的 探讨输尿管镜钬激光内切开术治疗输尿管狭窄的疗效。方法 本组10例输尿管狭窄，狭窄位于输尿管上段6例，中段1例，下段3例，输尿管狭窄段长度为0.3-1.8cm，采用输尿管镜钬激光(200μm激光光纤，输出能量0.8-1.0J，脉冲频率10-15Hz)内切开术治疗，术后留置1根或2根F5双J支架管，2-3个月后拔管。结果 手术时间30-50min，平均42min，无严重并发症，1例手术失败，余9例随访5-15个月，平均9.5个月，8例效果满意，1例术后3个月复发。结论 输尿管镜钬激光内切开术治疗输尿管狭窄具有创伤小、并发症少、恢复快等优点，是一种安全、有效的微创手术方式。

Treatment of ureteral strictures by holmium: YAG laser endoureterotomy
ABSTRACT: Objective To determine the efficacy of ureteral strictures treated by holmium: YAG laser endoureterotomy. Methods A total of 10 patients (5 women and 5 men, mean age 46 years) with ureteral strictures (6 in the upper, 1 in the mid, and 3 in the lower ureters) underwent holmium: YAG laser endoureterotomy using ureteroscopy and a 200microm fiber at 0.8-1 J and 10-15Hz. The length of ureteral strictures were from 0.3 to 1.8cm. Postoperatively, one or two F5 ureteral stents were remained indwelling for 2-3 months. Results The operative duration was 30-50min (average 42min). No severe complications were observed. 1 case was unsucc……
