目的：探讨输尿管镜气压弹道碎石术治疗输尿管结石的临床疗效。方法：应用输尿管镜气压弹道碎石术治疗输尿管结石28例。结果：26例中、下段输尿管结石中24例获得成功，2例失败。2例上段输尿管结石，因推入肾盂内改行ESWL。结论；输尿管镜气压弹道碎石术作为一种新兴技术，具有碎石时间短、效果明显、工作时不产生热、不易损伤组织、手术并发症少等优点，是很值得推广的。 Objective: To investigate the clinical efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods: Ureteroscopic pneumatic lithotripsy for the treatment of 28 cases of ureteral stones. Results: Twenty-four cases of ureteral calculi in the lower and middle stages were successful and two failed. 2 cases of upper ureteral calculi, into the renal pelvis due to divert ESWL. Conclusions; Ureteroscopy pneumatic lithotripsy as a new technology, with a short time, the effect is obvious, work does not produce heat, not easy to damage the organization, the advantages of fewer surgical complications, it is worth promoting.
