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。方法回顾性分析2008年3月至2012年2月采用输尿管镜气压弹道碎石术治疗的143例输尿管结石患者的临床资料,其中输尿管上段结石15例,中段57例,下段71例。结果本研究平均手术时间50 min(15～100 min),碎石成功率为96.5%(138/143),另外4例术后1～3周行体外冲击波碎石术治愈,1例中转开放手术治愈;均未出现输尿管穿孔或撕裂、感染、高热及大出血等严重手术并发症,术后1～3个月复查均未见输尿管结石残留及输尿管狭窄,肾积水均明显减轻或消失。结论输尿管镜气压弹道碎石术具有微创、高效、并发症少等优点,疗效确切、安全性高,是值得推广的输尿管结石的治疗方法。
Objective To investigate the clinical efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods The clinical data of 143 patients with ureteral calculi treated with ureteroscopic pneumatic lithotripsy from March 2008 to February 2012 were retrospectively analyzed. Among them, 15 cases had upper ureteral calculi, 57 cases had middle segment, and 71 patients had lower segment. Results In this study, the average operation time was 50 min (15-100 min), the success rate of gravel was 96.5% (138/143), and the other 4 patients were cured by extracorporeal shock wave lithotripsy 1 to 3 weeks after operation. One case was transferred to open surgery No perforation or tearing of ureter, infection, fever and bleeding and other serious complications were observed. No ureteral calculi, ureteral stricture and hydronephrosis were found in 1 ~ 3 months after operation, and hydronephrosis was significantly reduced or disappeared. Conclusions Ureteroscopic pneumatic lithotripsy has the advantages of minimally invasive, high efficiency and less complications, and has the advantages of definite curative effect and high safety. It is worth to be popularized in the treatment of ureteral calculi.
