目的讨论输尿管镜钬激光碎石术治疗输尿管结石的手术配合及疗效。方法对我院40例输尿管结石患者行钬激光碎石术的临床资料进行系统性回顾分析。结果40例输尿管结石患者中，38例治疗成功，成功率95%，手术时间15~80min，平均30min，术后无结石残留，无输尿管狭窄。结论输尿管镜钬激光治疗输尿管结石及膀胱结石创伤小，安全可靠，排石率高，良好的手术配合是手术顺利进行的关键。“,”Objective To study the ef ect and operational cooperation of holmium laser lithotripsy under ureteroscope in ureteral calculus. Methods We reviewed and analyzed the clinical datas of 40 patients with ureteral calculus whowere car ied out operations of holmium laser lithotripsy under ureteroscope. Results The probability of successful treatment was 95%(38in 40),the operation time was 15 and 80 minutes,the average surgery time was 30 minutes.There were no residual stones and no ureteral stricture. Conclusion Holmium laser lithotripsy under ureteroscope in ureteral stones and bladder stones issafe and reliable,andstone expulsion probability is high.Good operationalcooperation is the key to ensure the car ying out of the operation.
