目的　提高输尿管镜下气压弹道碎石术的技术水平 ,减少并发症的发生。方法　对采用输尿管镜下气压弹道碎石术治疗的 134例 (146侧 )输尿管结石患者的临床资料进行分析。结果　一次性碎石成功率 92 .4% (135 / 146 ) ;结石梗阻性脓肾 8例 ,其中 1例上段结石术中进入肾盂 ,置双J管后经体外碎石治愈 ;并发症发生率 3.4% (5 / 146 ) ,其中输尿管穿孔 1例 ,粘膜损伤、假道形成 2例 ,泌尿系感染 2例。结论　输尿管镜下气压弹道碎石术具有安全、微创等特点 ,是比较满意的输尿管结石腔内治疗方法 Objective To improve the technical level of pneumatic lithotripsy under ureteroscopy and reduce the incidence of complications. Methods The clinical data of 134 patients (146 sides) with ureteral calculi treated by ureteroscopic pneumatic lithotripsy were analyzed. Results The success rate of one-off gravel was 92.4% (135/146). There were 8 cases of obstructive pus in stone, of which 1 case had upper renal calculus and was treated with extracorporeal lithotripsy after double J-tube operation. Complication rate 3.4% (5/146), including 1 case of ureter perforation, mucosal injury, 2 cases of false passage formation and 2 cases of urinary tract infection. Conclusion ureteroscopic pneumatic lithotripsy is safe, minimally invasive and other characteristics, is more satisfactory ureteral calculi endovascular treatment
