ABSTRACT：Objective To evaluate the clinical efficacy and safety of micro-percutaneous nephrolithotomy （microPCNL） using Needle-perc in the oblique supine-lithotomy position for treating 1—2 cm lower-pole stones （LPSs），by comparing it with flexible ureteroscopic lithotripsy （FURL），so as to identify an effective surgical method for LPSs.Methods We retrospectively analyzed the clinical data of 56 patients with isolated LPSs of 1—2 cm treated in our hospital during Jan.and Dec.2023.Patients were divided into two groups based on the treatment method：FURL （n=31） and microPCNL （n=25）.General information and perioperative data were compared between the two groups.Results All operations were successfully completed.The operation time was shorter in the microPCNL group than in the FURL group ［（46.5±10.1） min vs.（73.5±18.9） min，P<0.001］.Stone-free rate （SFR） was 92.0% in the microPCNL group and 71.0% in the FURL group （P=0.026）.There were no significant differences in the average fall of hemoglobin level，serumc creatinine change level，hospitalization time and postoperative fever between the two groups.Conclusion MicroPCNL in oblique supine-lithotomy position is a safe and effective treatment for 1-2 cm LPSs，with a higher SFR compared to FURL.

摘要：目的 通过与输尿管软镜碎石术（FURL）比较，探讨斜仰卧-截石位下微小通道经皮肾镜取石术（microPCNL）治疗最大径1～2 cm肾下盏结石（LPSs）的临床疗效及安全性，寻找治疗肾下盏结石的有效手术方法。（剩余6707字）
