输尿管镜钬激光碎石治疗输尿管结石

目的 探讨输尿管镜钬激光碎石术治疗输尿管结石的有效性和安全性。方法 回顾性分析214例采用输尿管镜钬激光碎石治疗的输尿管结石患者资料。男134例，女80例；平均35岁。结石位于输尿管上段47例，中段63例，下段104例。结石直经0．5～2．6cm。平均1．2cm。结果 单次碎石成功率为95％（203／214）．其中上段结石单次碎石成功率87％（41／47）中、下段为98％（164／167）。平均手术30mim，术中无输尿管穿孔等并发症发生。平均住院2．5d，197例随访1～3个月，结石排净率98％，无输尿管狭窄发生。结论 输尿管镜钬激光碎石治疗输尿管结石创伤少，成功率高，是首选的治疗方法。

Transureteroscopic and holmium: YAG laser lithotrpsy for treatment of ureteral calculi

[Objective] To evaluate the efficacy and safety of Transureteroscopic lithotripsy with holmium. [Methods] 214 cases ureteral calculi treated with Transuteteroscopic laser lithotripsy from Feb. 2000 to Dec. 2003 were studied retrospectively. There were 134 male patients and 80 female with an average age of 35, 47 being upper ureteral stone, 63 middle and 104 lower ureteral stone. The stones were 0.5 to 2.6 cm (mean 1.2 cm) in diameter. [Results] The overall rate of successful fragmentation for all levels of utrteral stones in a single procedure achievevd 95% (203/214), The success rates of fragmentation in single procedure for the upper and mid-lower legels of ureteral stones were 87% (41/47) and 98% (164/167). The mean operative time was 30 min. No complications such as perforation occurred during the operation. The mean postoperative hospital stay was 2.5 days. In 197 patients, the postoperatve follow-up of 1 month to 3 months revealed that the stone-free rate was 98%. No ureteral stenosis occurred. [Conlusions] Treatment of ureteral calculi by transureteroscopic laser lithotripsy has geen safe and effective. It can be considered as the first choice of treatment.
