目的探讨肾微穿刺造瘘灌注下经尿道输尿管镜双频双脉冲激光碎石术治疗输尿管上段嵌顿性结石的疗效及安全性。方法回顾性分析2010年5月～2012年10月本院应用肾微穿刺造瘘灌注下经尿道输尿管镜双频双脉冲激光碎石术治疗的25例输尿管上段嵌顿性结石患者的临床资料。结果术后3 d复查结石清除率为37.5%(9/24),所有患者均未见直径>4 mm结石残留,治疗成功率为96%(24/25)。结论肾微穿刺造瘘灌注下经尿道输尿管镜双频双脉冲激光碎石术治疗输尿管上段嵌顿性结石安全有效。
Objective To investigate the efficacy and safety of transurethral ureteroscopic dual-frequency and double-pulse laser lithotripsy in the treatment of incarcerated ureteral calculi under renal microperitoneal perfusion. Methods The clinical data of 25 patients with upper ureteral incarcerated stones underwent ureteroscopic double-frequency double-pulse laser lithotripsy undergoing renal microperitoneal perfusion in our hospital from May 2010 to October 2012 were retrospectively analyzed. Results The stone clearance rate was 37.5% (9/24) 3 days after operation. All the patients had no residual stones> 4 mm in diameter. The success rate was 96% (24/25). Conclusions Transurethral ureteroscopic dual-frequency and double-pulse laser lithotripsy for the treatment of upper ureteral incarcerated stones under renal micro-peritoneal ostomy perfusion is safe and effective.
