目的:探讨GPS超声在经皮肾镜碎石取石术(PCNL)中建立皮肾通道的应用价值。方法:2014年1月~2015年6月应用GPS超声引导建立皮肾通道行PCNL治疗上尿路结石54例,对其方法、通道建立时间、清石率、手术并发症等进行回顾性分析。结果:54例均一次性成功建立皮肾通道,建立皮肾通道时间5~10min,平均(6.2±1.3)min,单通道45例,双通道9例。一期清石率90.7%(49/54);无肾切除、腹腔脏器损伤、血气胸等严重并发症。结论:GPS超声引导建立皮肾通道行PCNL具有术中实时监控、定位准确、穿刺时间短、避免盲目性穿刺的优势,是一种安全有效的超声定位穿刺方法。
Objective: To investigate the value of GPS ultrasonography in establishing percutaneous nephrolithotomy in percutaneous nephrolithotomy (PCNL). Methods: From January 2014 to June 2015, 54 cases of upper urinary tract stones treated with PCNL guided by GPS ultrasound were guided by GPS ultrasound. The method, the time of channel establishment, the rate of clear stone and the complications were retrospectively analyzed. Results: All the 54 cases were successfully established the renal access, the time of establishing the renal access was 5 ~ 10min, the average was (6.2 ± 1.3) min, 45 were single and 9 were dual. A clear rate of 90.7% (49/54); no nephrectomy, abdominal organ injury, severe pneumothorax and other complications. CONCLUSION: GPS ultrasound-guided PCNL is a safe and effective method for ultrasound-guided percutaneous puncture. It has the advantages of real-time monitoring during operation, accurate positioning, short puncture time and avoiding blind puncture.
