目的探讨输尿管镜下气压弹道碎石术治疗输尿管结石的疗效.方法输尿管镜下气压弹道碎石术治疗输尿管结石112例.输尿管上段结石5例,中段结石64例,下段结石43例.其中结石位于左侧60例.右侧52例,双侧2例.结果112例输尿管结石粉碎106例(94.6%),3例结石移动至肾盂未完成手术,2例置镜失败而改成开放手术,1例发生输尿管下段穿孔经放置双J管内引流后改行其他方法治疗.60例(53.6%)术后有肉眼或镜下血尿.所有病例无尿路感染、输尿管黏膜剥脱、撕裂及狭窄等严重并发症.结论输尿管镜直视下气压弹道碎石术治疗输尿管结石,碎石确切、安全、组织损伤小,清除彻底,并发症少,可视为输尿管中段和下段结石的首选治疗方法.
Objective To investigate the efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi.Methods Ureteroscopic pneumatic lithotripsy was used to treat 112 cases of ureteral calculi.The upper ureteral calculi in 5 cases, the middle section of calculi in 64 cases, the lower section of calculi in 43 cases, 60 cases on the left side, 52 cases on the right side and 2 cases on both sides.Results In 112 cases, ureteral calculi was smashed in 106 cases (94.6%), 3 cases moved to the renal pelvis in the unfinished operation, Cases occurred in the lower ureter perforation after placement of double J tube drainage and diverted to other methods.60 (53.6%) had macroscopic or microscopic hematuria.All cases without urinary tract infection, ureteral mucosal exfoliation, tearing and stenosis and other serious complications Conclusion ureteroscopic pneumatic lithotripsy for the treatment of ureteral stones, the exact gravel, safety, tissue damage, complete removal, fewer complications, can be considered as the preferred treatment of middle and lower ureteral stones.
