经皮肾微造瘘通道肾镜治疗肾结石

目的：探讨经皮肾微造瘘通道肾镜治疗肾结石的方法和效果。方法：回顾分析37例采用经皮肾镜取石术（PCNL）治疗的。爵结石患者的临床资料，37例均建立了Fr16或Fr18的经皮肾通道，经肾镜行气压弹道及钬激光碎石术治疗。结果：37例行I期穿刺并同时碎石，其中28例I期碎石清石成功，7例需Ⅱ期手术碎石清石．2例通过Ⅲ期手术碎石清石。单通道取石32例，双通道取石5例，碎石清除率为91．9％。手术时间60－160min．平均84min，术中均未输血。结论：经皮肾微造瘘通道肾镜治疗肾结石，具有创伤小、出血少及并发症少的优点．是治疗复杂肾结石的较好方法。

Treatment of nephrolithiasis with micro-fistula percutaneous channel through nephroscope

Objective ：To discuss the method and effect of treatment of nephrolithiasis with micro-fistula percutaneous channel through nephroscope.Methods：The percutaneous nephrolithotripsy materials of 37 cases of those patients were analyzed retrospectively.All the cases had performed with pneumatic or holmium laser lithotripsy.Results：Thirty seven sides stone cases were finished in one stage.A complementary stone removal was needed in 7 patients, and 2 patients underwent three times of operation.A single tract was used in 32 patients and double tracts in 5 patients.The operation time was from 60 to 160 minutes（mean 84 minutes）.The stone-free rate was 91.9%（32/37） and without blood transfusion.Conclusion：This method might have less injury,less bleeding and less complication so that it improve the successful rate and is a kind of effective and minimally invasive technique for complicated renal calculi.
