目的　观察输尿管肾镜气压弹道碎石术在治疗复杂性肾结石中的疗效。方法　总结分析应用经皮肾穿刺造瘘输尿管肾镜气压弹道碎石术治疗复杂性肾结石 14例的临床资料。结果　 13例复杂性肾结石治疗一期碎石成功 ,1例因积脓延期碎石 ,一期碎石成功率达 92 .9%。术后一月结石排净率达 71.4%。结论　经皮肾穿刺造瘘输尿管肾镜气压弹道碎石术治疗复杂性肾结石具有安全 ,高效 ,微创 ,并发症少 ,疗效确切等优点。经皮肾穿刺造瘘准确至结石所在部位是碎石成功的关键 ,术后均应放置内引流支架管。 Objective To observe the efficacy of ureteroscopic pneumatic lithotripsy in the treatment of complex renal calculi. Methods The clinical data of 14 cases with complicated renal calculus treated with percutaneous nephrostomy and ureteroscopic pneumatic lithotripsy were summarized and analyzed. Results 13 cases of complex renal stone treatment of a gravel success, 1 case of postoperative suppurative extension of gravel, a gravel success rate of 92.9%. The stone clearance rate reached 71.4% in January after operation. Conclusion Percutaneous nephrostomy ureteroscopic pneumatic lithotripsy for the treatment of complex renal stones with safety, high efficiency, minimally invasive, fewer complications, the exact effect and so on. Percutaneous nephrostomy fistula accurate to the stone site is the key to the success of gravel, postoperative drainage catheter should be placed inside.
