目的探讨输尿管镜气压弹道碎石术治疗输尿管中下段结石的疗效。方法选择2008年2月至2011年2月我院收治的55例输尿管中下段结石患者,其中部分为结石时间较长、嵌顿息肉包裹者,均行输尿管镜下气压弹道碎石术。结果 1次碎石、取石成功成功率为92.7%(51/55),平均手术时间25min。其中1例改行开放性手术,3例术后1～2周行体外震波碎石术(ESWL)1～2次;术后高热4例,大多数患者均出现轻度肉眼血尿,未见输尿管穿孔、撕裂等严重并发症。结论输尿管镜气压弹道碎石术具有创伤小、碎石可靠、安全等优点,是输尿管中下段结石的首选治疗手段。
Objective To investigate the efficacy of ureteroscopic pneumatic lithotripsy in the treatment of lower ureteral calculi. Methods From February 2008 to February 2011, 55 cases of ureteral calculi in our hospital were admitted to our hospital. Some of them were those with longer stones and incarcerated polyps. All underwent ureteroscopic pneumatic lithotripsy. Results The success rate of primary lithotripsy and stone extraction was 92.7% (51/55) and the average operation time was 25 minutes. Among them, 1 case underwent open surgery and 3 cases underwent ESWL 1 ~ 2 weeks after operation. In 4 cases, high fever occurred in most patients, and no ureteral perforation occurred in most of the patients. , Tear and other serious complications. Conclusions Ureteroscopic pneumatic lithotripsy has the advantages of less trauma, reliable and safe gravel, and is the treatment of choice for stones in the lower ureter.
