输尿管镜下钬激光内切开术治疗输尿管狭窄35例分析

Endoscopic ureteral excision using holmium laser in the treatment of ureterostenosis

目的探讨输尿管镜下钬激光内切开术治疗输尿管狭窄的方法及疗效。方法采用输尿管镜下钬激光内切开术治疗35例输尿管狭窄患者，术中均留置双J管，于术后8～12周拔除，拔管后3-6个月行超声、排泄性尿路造影榆查。结果35例均手术成功，术后随访6～24个月，平均14个月。31例治愈（治愈率88．57％），2例好转（5．71％），2例无效（5．71％）。结论输尿管镜下钬激光内切开术治疗输尿管狭窄，具有创伤小、疗效好、并发症少、安全、可反复操作的优点，值得推广。

Objective To discuss the method and curative effect of ureterostenosis with incision of holmium laser under ureteroscope. Methods 35 patients with ureterostenosis received ureteral incision by using holmium laser under a endoscope. Two double pig tail stents were placed in the ureters after the operation and left indwelling for 8 to 12 weeks. Ultrasonography and excretion arography were performed 3 to 6 months after extubation. Results Follow - up was available tor 6 to 24 months （ mean, 14 months） in 35 patients, of which 31 （88.57%） were cured after the treatment. In the other 4 patients, 2 （ 5.71% ） were improved after the treatment and 2 （5.71% ） failed. Conclusion Endoscopic ureter- al excision using holmium laser is a safe, effective method with little side effects and worth spread.
