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,Plt;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 通過與輸尿管軟鏡碎石術(FURL)比較,探討斜仰臥-截石位下微小通道經皮腎鏡取石術(microPCNL)治療最大徑1~2 cm腎下盞結石(LPSs)的臨床療效及安全性,尋找治療腎下盞結石的有效手術方法。方法 回顧性分析2023年1—12月武漢大學人民醫(yī)院泌尿外科收治的56例直徑1~2 cm的孤立性LPSs患者的臨床資料,根據治療方式分為FURL組(截石位下FURL,n=31)和microPCNL組(斜仰臥-截石位下microPCNL,n=25),比較兩組患者的一般資料及圍手術期資料。結果 兩組手術均順利完成,microPCNL組較FURL組患者手術時間更短[(46.5±10.1)min vs.(73.5±18.9)min,Plt;0.001],結石清除率(SFRs)更高(92.0% vs. 71.0%,P=0.026),而兩組患者在平均血紅蛋白下降水平、血肌酐變化水平、術后住院時間及術后發(fā)熱等方面的差異無統(tǒng)計學意義(P>0.05)。結論 斜仰臥-截石位下microPCNL用于治療1~2 cm的LPSs安全有效,且SFRs高于FURL。

隨著腎結石發(fā)病率的上升,其治療方式也層出不窮,體外沖擊波碎石術(extracorporealshock wave lithotripsy,ESWL)、輸尿管軟鏡碎石術(flexible ureteroscopic lithotripsy,FURL)和經皮腎鏡取石術(percutaneous nephrolithotomy,PCNL)是治療腎結石的常用方法[1]。結石大小是決定腎結石治療方式的重要因素,但對于腎下盞結石(lower-pole stones,LPSs),下盞的解剖結構是其治療選擇的另一決定性因素。目前,對于最大徑1~2 cm的LPSs,其治療方案的選擇在臨床上一直存在爭議,ESWL的結石清除率(stone-free rates,SFRs)約41.2%~77.9%,低于PCNL(66.7%~99.1%)和FURL(42.9%~97.3%)[2],PCNL雖然SFRs高,但術后并發(fā)癥發(fā)生率高于其他2種方式[3];……
