目的探讨超声引导下经上盏径路微创经皮肾碎石术(MPCNL)治疗上尿路结石的疗效及安全性。方法2006年3月至2009年3月,对76例82侧上尿路结石使用超声引导下经上盏径路MPCNL。穿刺点选择在肩胛下线和腋后线之间第10、11肋间,超声定位下穿刺后组上盏建立通道,使用U-100双频双脉冲Nd:YAG激光碎石。结果82侧手术均获成功,平均手术时间(45±10)min。一期结石取净率为81.7%(67/82),二期结石取净率为73.3%(11/15)。输血1例,胸腔积液2例,无重要脏器损伤及其他严重并发症。结论超声引导下经上盏径路微创经皮肾镜碎石术高效、微创、安全。
Objective To investigate the efficacy and safety of ultrasonography guided minimally invasive percutaneous nephrolithotomy (MPCNL) on upper urinary calculi. Methods From March 2006 to March 2009, 76 cases of 82-sided upper urinary tract stones underwent ultrasound-guided MPCNL. The puncture points were selected between the subscapular line and the posterior axillary line 10,11 between the intercostal ultrasound puncture group after setting up the channel to use U-100 dual-frequency dual-pulse Nd: YAG laser lithotripsy. Results All the 82 surgeries were successful, with an average operation time of (45 ± 10) min. The first stone removal rate was 81.7% (67/82), the second stone removal rate was 73.3% (11/15). Transfusion in 1 case, pleural effusion in 2 cases, no important organ injury and other serious complications. Conclusion Ultrasound-guided minimally invasive percutaneous nephrolithotomy is an efficient, minimally invasive and safe method.
