The aim of this study was to assess the clinical outcomes of mini-percutaneous nephrolithotomy (Miniperc) and shock wave lithotripsy (SWL) for medium-sized renal stones.
A literature search was performed in February 2020 using the Pubmed, Web of Science and Embase. The outcome measurements between two procedures were stone-free rates (SFR), complication rates, operative time, hospitalization stay time, re-treatment rate, auxiliary procedures rate and efficiency quotient. Results were pooled by Review Manager version 5.3 software.
Seven studies on 936 patients (N.=471 for SWL and N.=465 for Miniperc) were included. Miniperc was associated with a higher SFR (OR: 0.25; P<0.00001). In addition, we performed a subgroup analyses for pediatric renal stones and lower pole stones, pooled results also favored Miniperc for higher SFR. SWL was associated with higher auxiliary procedure (OR: 3.32; P<0.00001), higher re-treatment rate (OR: 19.19; P<0.00001) and lower EQ (OR: 0.18; P=0.0003) compared with Miniperc. Besides, SWL was associated with a lower complication rate (OR: 0.36; P=0.0001), shorter operative time (WMD: -34.01; P<0.00001), fluoroscopy time (WMD: -134.48; P<0.00001) and hospital time (WMD: -49.11; P<0.00001) compared with Miniperc.
Miniperc offers a significantly higher SFR, lower auxiliary procedure and re-treatment rate, but SWL was associated with fewer complications.
本研究旨在评估微创经皮肾镜取石术（Miniperc）和体外冲击波碎石术（SWL）治疗中等大小肾结石的临床效果。
2020 年 2 月，我们通过 Pubmed、Web of Science 和 Embase 进行了文献检索。两种方法的主要疗效指标是结石清除率（SFR）、并发症发生率、手术时间、住院时间、再次治疗率、辅助治疗率和效率指数。结果通过 Review Manager 版本 5.3 软件进行汇总。
共纳入 7 项研究 936 例患者（SWL 组 N=471，Miniperc 组 N=465）。Miniperc 组的 SFR 更高（OR：0.25；P<0.00001）。此外，我们还对儿童肾结石和下极肾结石进行了亚组分析，汇总结果也显示 Miniperc 组的 SFR 更高。SWL 组的辅助治疗率（OR：3.32；P<0.00001）、再次治疗率（OR：19.19；P<0.00001）和效率指数（OR：0.18；P=0.0003）均低于 Miniperc 组。此外，SWL 组的并发症发生率（OR：0.36；P=0.0001）、手术时间（WMD：-34.01；P<0.00001）、透视时间（WMD：-134.48；P<0.00001）和住院时间（WMD：-49.11；P<0.00001）均短于 Miniperc 组。
Miniperc 组结石清除率更高，辅助治疗率和再次治疗率更低，但 SWL 组并发症发生率更低。
