输尿管镜气压弹道碎石治疗输尿管结石110例

Treatment of ureteral calculi with ureteroscopy and pneumatic lithotripsy: A report of 110 cases

目的总结输尿管镜气压弹道碎石治疗输尿管结石的临床效果. 方法采用F8/9.8Wolf硬性输尿管镜、JUN-AIR气压弹道碎石机治疗110例输尿管结石. 结果输尿管镜直视下一次碎石成功105例,成功率95.5%(105/110),1～6周内结石全部排净.2例因置镜失败改开放手术,3例输尿管上段结石上移至肾脏行ESWL 2例,口服排石药物治疗1例.术后泌尿系感染5例,轻度肉眼血尿1～3 d. 结论输尿管镜气压弹道碎石是治疗输尿管中、下段结石的有效方法之一,具有碎石率高、安全、并发症少、操作简单的优点.

Objective To evaluate the clinical efficacy of pneumatic lithotripsy under ureteroscope in the treatment of ureteral calculi. Methods A total of 110 cases of ureteral calculi were treated by using 8/9.8 F Wolf rigid ureteroscope and JUN - AIR pneumatic lithotripter. Results Successful lithotripsy under ureteroscope was achieved on one session in 105 cases, with a success rate of 95.5% （105/110）. Calculi were entirely extracted within 1 -6 weeks, Conversions to open surgery were required in 2 cases because of failed ureteroscope insertion. Upper ureteral stones moved into the kidney in 3 cases, 2 of which underwent the ESWL and 1 of which received medical treatment. Postoperatively, 5 cases were complicated with urinary infection with mild hematuria lasting for 1 -3 days. Conclusions Pneumatic lithotripsy under ureteroscope is an effective method for treating mid - lower ureteral calculi,with advantages of high efficiency, safety, minimal invasion, less complications and simplicity of performance.
