应用经皮肾镜气压弹道—超声碎石清石系统治疗复杂性肾结石

目的探讨经皮肾镜气压弹道一超声碎石清石系统治疗复杂性肾结石的安全性及疗效。方法采用经皮肾镜气压弹道一超声碎石清石系统治疗46例复杂性肾结石。结果I期结石清除率82．6％（38／46），解除肾盂梗阻100％，手术时间40-95min，平均72min。11期手术结石清除率62．5％（5／8），3例残余肾结石予EswL及药物排石治疗，2例结石排净，结石总清除率97．8％。所有患者均无严重并发症。结论经皮肾镜气压弹道一超声碎石清石系统具有高效、安全的特点，是治疗复杂性肾结石的理想选择。

Clinical Evaluation of Combined Pneumatic and Ultrasound Lithotripsy for Complex Renal Calculi

Objective To evaluate the safety and clinical efficacy of combined pneumatic and ultrasound lithotripsy for complex renal calculi with simultaneous percutaneous nephrolithotomy. Methods 46 cases with complex renal calculi underwent simultaneous percutaneous nephrolithotomy （PCNL） by ultrasonic power of Swiss Lithoclast Master（ EMS IV. Switzerland） with positioning perspective of B-uhrasonography. Results All the operations were successful and no case had severe complications during surgery with the postoperative follow-up for 1 -3 months. The one-stage operation curative rate was 82.6% （38/46）. The operative time was 40 -75 min,and average time consumption was 58 minutes for the operation. The two-stage operation curative rate was 62.5% （5/8）. Three patients accepted extracorporeal shock wave lithotripay and drug treatment. The overall stone-clearance rate was 97.8%. Conclusion Percutaneous nephrolithotomy with EMS IV for complex renal calculi is recommended for the safety high efficiency and minimal invasion in performance.
