微创经皮肾镜取石术治疗输尿管上段结石

Treatment of proximal ureteral calculi with mini-percutaneous nephrolithotomy

目的 探讨经皮肾穿刺造瘘取石术 (PCNL)治疗输尿管上段结石的安全性与有效性。 方法 回顾性分析 10 9例采用PCNL治疗的输尿管上段结石患者资料。男 6 1例 ,女 4 8例 ;年龄 12～ 6 7岁。结石直径 1.0～ 3.5cm。 结果 10 9例均为一期取石 ,结石清除率 10 0 % ,平均手术时间6 0min ,术中估计出血量平均 2 5ml,平均住院时间 7d ,无严重并发症发生。 结论 PCNL治疗输尿管上段结石安全有效 ,可以使绝大多数患者避免开放手术。

Objective To evaluate mini-percutaneous nephrolithotomy in treating proximal ureteral calculi. Methods 109 patients underwent mini-percutaneous nephrolithotomy for proximal ureteral calculi from March 1998 to July 2001 were reviewed and evaluated. Results All the 109(100%) were rendered stone-free at 1 session.The average operation time was 60 munites,the estimated blood loss volume 25 ml and the average hospitalization 7 days.No major complications were noted. Conclusions Mini-percutaneous nephrolithotomy is safe and effective in treating proximal ureteral calculi and is less invasive for the patients.
