目的探讨经皮肾镜气压弹道联合超声碎石、清石术治疗输尿管上段结石的临床疗效。方法对2004年1月至2005年10月采用B超引导下经皮肾镜气压弹道联合超声碎石、清石设备治疗的73例输尿管上段结石患者的资料进行回顾性分析。结果73例患者在B超引导下均成功建立皮肾通道并Ⅰ期处理结石．均为单通道碎石。结石清除率为100%；平均手术时间为41min,平均住院时间为8d,未发生严重并发症。结论经皮肾镜气压弹道联合超声碎石、清石术可以有效地治疗输尿管上段结石。 Objective To investigate the clinical effect of percutaneous nephrolithotomy combined with ultrasonic lithotripsy and lithotripsy in the treatment of upper ureteral calculi. Methods The data of 73 cases of upper ureteral calculi treated by B-guided percutaneous nephroscope, pneumatic lithotripsy and ultrasonic lithotripsy and clear stone equipment were retrospectively analyzed from January 2004 to October 2005. Results 73 cases of patients under the guidance of B ultrasound successfully established the renal access and the first phase of stone treatment. Are single-channel gravel. Stone clearance rate was 100%; the average operation time was 41min, the average hospital stay was 8d, no serious complications. Conclusion Percutaneous nephrolithotomy combined with ultrasonic lithotripsy and lithotripsy can effectively treat upper ureteral calculi.
