To compare the outcomes among upper calyx, middle calyx, and lower calyx access in complete ultrasound-guided percutaneous nephrolithotomy (PCNL) for single renal pelvic stone. Between July 2014 and September 2015, the data of 153 patients with single renal pelvic calculi were retrospectively reviewed in this study and patients were divided to group 1 (45 patients, upper calyx access), group 2 (57 patients, middle calyx access), and group 3 (51 patients, lower calyx access). Preoperative characteristics and intraoperative and postoperative parameters were analyzed and compared. A p value of <0.05 was considered significant. Important patient- and stone-related parameters were similar among the three groups. The mean operative time was significantly shorter in the middle calyx group than the lower and upper calyx groups (41.2 ± 6.9 vs. 50.2 ± 9.3 and 46.0 ± 9.6 min, respectively). The middle calyx group had a higher stone-free rate than the lower and upper calyx groups (98.20 vs. 84.3 % and 93.3 %, respectively, p = 0.037). There were no significant differences in mean postoperative hemoglobin decrease and incidence of complications among groups (p = 0.42 and 0.862, respectively). Middle calyx access achieved superior outcomes for removal of single renal pelvic stone via ultrasound-guided PCNL.
比较完全超声引导下经皮肾镜取石术（PCNL）治疗单一肾盂结石时，上盏、中盏和下盏入路的疗效。2014年7月至2015年9月，本研究回顾性分析了153例单一肾盂结石患者的数据，并将患者分为1组（45例，上盏入路）、2组（57例，中盏入路）和3组（51例，下盏入路）。分析并比较术前特征以及术中和术后参数。p值<0.05被认为具有统计学意义。三组患者重要的患者和结石相关参数相似。中盏组的平均手术时间显著短于下盏组和上盏组（分别为41.2±6.9分钟、50.2±9.3分钟和46.0±9.6分钟）。中盏组的结石清除率高于下盏组和上盏组（分别为98.20%、84.3%和93.3%，p=0.037）。各组术后平均血红蛋白下降幅度和并发症发生率无显著差异（分别为p=0.42和0.862）。通过超声引导PCNL治疗单一肾盂结石，中盏入路取得了更好的疗效。
