目的探讨双微通道经皮肾镜碎石术处理复杂性肾结石的临床效果。方法 164例复杂性肾结石通过双微通道(16F或18F及20F)经皮肾镜下碎石治疗,观察其临床效果。结果 103例通过一期手术治疗,结石清除率为88.3%,61例通过二期手术处理,结石清除率为91.8%。164例患者,平均出血约50 ml,其中2例出血约300 ml,术后有输血,无严重冲洗液外渗、肾周积脓,均无大出血,胸膜、结肠损伤等严重并发症。结论双微通道经皮肾镜碎石术处理复杂性肾结石,特别是无积水铸型结石,能更好的减少并发症,有效清除结石。
Objective To investigate the clinical effect of dual microchannel percutaneous nephrolithotomy on complicated renal calculi. Methods One hundred and sixty four cases of complex renal calculi were treated with percutaneous nephrolithotomy via double microchannels (16F or 18F and 20F). The clinical effect was observed. Results One hundred and three patients underwent primary surgery. The stone removal rate was 88.3%. Sixty-one patients underwent second-stage surgery with a stone clearance rate of 91.8%. 164 patients, the average bleeding about 50 ml, of which 2 cases of bleeding about 300 ml, postoperative blood transfusion, no serious irrigation fluid extravasation, empyema perianal, no bleeding, pleural, colon injury and other serious complications. Conclusions Dual microchannel percutaneous nephrolithotripsy treat complex nephrolithiasis, especially non-hydrostatic cast stone, can better reduce complications and effectively remove stones.
