目的 :探讨输尿管肾镜气压弹道碎石技术在治疗输尿管结石中的作用。方法 :分析 16 9例输尿管结石患者应用该方法治疗的经验及教训。结果 :16 9例中 16 4例原位碎石成功 ,成功率达 97.0 % ;平均碎石时间 (5 .8± 2 .9) m in,术后 3 d～ 1个月碎石排净率达 98.1%。结论 :经输尿管肾镜气压弹道碎石治疗输尿管结石安全、微创、高效。输尿管肾镜的置入和结石的相对固定是碎石成功的关键。术后均应置放内引流支架管
Objective: To investigate the role of ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods: The experience and lessons of 169 cases of ureteral calculi treated by this method were analyzed. Results: Among 164 cases, 16 4 cases were successfully treated with in situ gravel, the success rate was 97.0%. The average gravel time was (5.8 ± 2.9) mm and the rate of gravel rejection was 3 days to 1 month after operation Up to 98.1%. Conclusion: The ureteroscopic pneumatic lithotripsy for the treatment of ureteral calculi is safe, minimally invasive and effective. Ureteroscopic nephrolithiasis and the relative fixation of stone is the key to the success of gravel. Postoperative drainage catheter should be placed within the stent
