目的:探讨B超引导下经皮肾穿刺取石术治疗上尿路结石的临床应用价值。方法:回顾分析2011年2月~2013年8月在B超引导下MPCNL治疗上尿路结石病例285例的临床资料,285例均在B超引导下建立F16或F18的经皮肾通道,行输尿管硬镜气压弹道碎石术治疗。结果:285例上尿路结石患者均成功穿刺并建立经皮肾通道,一期取石239例,二期取石43例,三期取石3例。结石清除率85.9%,平均手术时间81min,术中出血平均85ml,1例迟发性出血经保守治疗痊愈。结论:B超引导下经皮肾穿刺取石术治疗上尿路结石能够有效安全的选择合理的穿刺通道路,提高目标肾盏穿刺准确度,减少手术并发症,提高结石清除率。
Objective: To investigate the clinical value of percutaneous nephrolithotomy guided by B-ultrasonography in the treatment of upper urinary tract calculi. Methods: The clinical data of 285 cases of upper urinary tract calculi treated with B-guided MPCNT from February 2011 to August 2013 were retrospectively analyzed. 285 cases underwent percutaneous renal access with F16 or F18 guided by B-mode ultrasonography. Ureteroscopic pneumatic lithotripsy treatment. Results: 285 cases of upper urinary tract stones were successfully puncture and the establishment of percutaneous renal access, a stone in 239 cases, 43 cases of second stage, three cases of stone in 3 cases. Stone clearance rate of 85.9%, the average operation time 81min, intraoperative bleeding average 85ml, 1 case of delayed hemorrhage cured by conservative treatment. CONCLUSION: Percutaneous nephrolithotomy guided by B-ultrasonography can effectively and safely select the appropriate puncture access, improve the accuracy of target calyceal puncture, reduce surgical complications and improve the rate of stone removal.
