目的 研究内窥镜直视下腔内碎石术治疗泌尿系结石的临床疗效。方法 1 996年 5月～ 2 0 0 2年 1 2月期间对 2 8例肾结石、1 2 0 5例输尿管结石、1 2例尿道结石及 33例膀胱结石行腔内机械碎石术、超声碎石术、气压弹道碎石术以及钬激光碎石术。结果 肾多发结石行微创经皮肾输尿管镜碎石术成功率 96.4% (2 7/ 2 8) ;输尿管结石碎石成功率 98.1 % (1 1 81 / 1 2 0 5) ;失败主要原因为输尿管狭窄 6例、输尿管纤维性扭曲 5例、结石游走 8例 ,并发症主要为输尿管穿孔 5例 0 .45% (5/ 1 2 0 5) ;尿道膀胱结石成功率 1 0 0 %。结论 窥镜直视下腔内碎石术治疗泌尿系结石安全、有效并且微创 ,特别适用于泌尿系结石的急诊处理
Objective To study the clinical efficacy of endoscopic lithotripsy for urinary calculi. Methods From May 1996 to February 2002, 28 cases of renal calculi, 1205 cases of ureteral calculi, 12 cases of urethral calculi and 33 cases of bladder calculi underwent mechanical lithotripsy, ultrasonic broken Stone surgery, pneumatic lithotripsy and holmium laser lithotripsy. Results The success rate of minimally invasive percutaneous nephrolithotomy lithotripsy was 98.4% (21/28) for ureteral calculi and 98.1% (11 81/1205) for ureteral calculi. The main reason for the failure was Ureteral stenosis in 6 cases, ureteral fibrosis in 5 cases, walking in 8 cases of stones, complications were mainly ureteral perforation in 5 cases 0.45% (5/1205); urethral bladder stone success rate was 100%. Conclusion Endoscopic lithotripsy for the treatment of urinary stones is safe, effective and minimally invasive, especially for the emergency treatment of urolithiasis
