目的观察输尿管镜下双频双脉冲激光治疗输尿管中下段结石的疗效。方法应用输尿管镜及双频双脉冲激光对80例输尿管中下段结石进行碎石治疗。结果 80例中一次性碎石成功率为92.5%(74/80),其中输尿管中段结石一次碎石成功率为86.2%(25/29),输尿管下段结石一次碎石成功率为96.1%(49/51);碎石失败6例,其中1例输尿管穿孔改开放手术。激光碎石成功患者术后除出现血尿外,未发生其他严重并发症。结论输尿管镜下双频双脉冲激光碎石术具有快速、安全、微创、碎石成功率高、操作简单和患者康复快等优点,是目前治疗输尿管中下段结石的理想方法。
Objective To observe the effect of ureteroscopic dual-frequency and double-pulse laser in the treatment of lower ureteral calculi. Methods Ureteroscope and double-frequency double-pulsed laser were used to treat 80 cases of middle and lower ureteral calculi. Results The success rate of primary ureteral stones was 92.5% (74/80) in 80 cases. The success rate of primary ureteral stones was 86.2% (25/29), and the success rate of primary ureteral lithotripsy was 96.1% (49 / 51); gravel failure in 6 cases, of which 1 case of ureter perforation change open surgery. In addition to hematuria after successful laser lithotripsy, no other serious complications occurred. Conclusions Ureteroscopic dual-frequency and double-pulse laser lithotripsy is an ideal method for the treatment of stones in the lower ureter at present because of its advantages of fast, safe, minimally invasive, high success rate of lithotripsy, simple operation and quick recovery.
