目的探讨留置输尿管外支架的输尿管下段结石气压弹道碎石术的安全性和有效性。方法前瞻性收集2013年1月至2015年2月我院86例简单输尿管下段结石行输尿管镜气压弹道碎石术患者的资料。采用随机数字表法分为观察组42例(留置外支架管),对照组44例(放置双J管2周),将手术时间、术后不适症状、术后残石率和并发症作为评价的指标。结果两组的手术时间及术后残石率比较无统计学意义(P>0.05)。观察组在膀胱刺激症状、血尿和腰痛发生率均明显少于对照组,且持续时间明显缩短,差异具有统计学意义(P<0.05)。结论在严格选择患者的前提下,留置输尿管外支架的输尿管下段结石气压弹道碎石术是安全和有效的。
Objective To investigate the safety and effectiveness of pneumatic ureteral lithotripsy in the lower ureteral calculi with indwelling ureteral stent. Methods The data of 86 patients with simple ureteral calculi underwent ureteroscopic pneumatic lithotripsy in our hospital from January 2013 to February 2015 were prospectively collected. Using random number table divided into observation group 42 cases (indwelling stent), control group 44 cases (double J tube placed for 2 weeks), the operation time, postoperative discomfort symptoms, postoperative residual stone rate and complications as an evaluation index of. Results There was no significant difference between the two groups in the operation time and postoperative residual stone ratio (P> 0.05). The incidence of bladder irritation, hematuria and back pain in the observation group were significantly less than those in the control group, and the duration was significantly shortened (P <0.05). Conclusions In the strict selection of patients under the premise of leaving ureteral stent in the lower ureteral calculi pneumatic lithotripsy is safe and effective.
