Abstract：Objective To evaluate the safety and efficacy of non-retrograde intubation combined with selectively tubeless percutaneous nephrolithotomy(NR-ST-PCNL).Methods A retrospective analysis included 213 patients with upper urinary tract stones and hydronephrosis(renal pelvic separation>10 mm)undergoing PCNL at our hospital from October 2023 to June 2025.Patients were divided into Group A(non-retrograde intuba-tion,n=109)and Group B(retrograde intubation,n=104).Primary endpoint was postoperative complications and secondary endpoints included operative time,stone-free rate(SFR),visual analog scale(VAS)pain scores,postoperative hospital stay,and hospitalization costs.Results Group A demonstrated significantly lower rates of postoperative complications[7.3%(8/109)vs.18.2%(19/104),P=0.017],shorter operative time[51.00(37.00,65.00)min vs.71.50(55.00,90.75)min,P<0.001],lower postoperative VAS scores[1.00(0.00,1.00)vs.1.00(0.00,2.00),P=0.008],shorter hospital stay[3.00(2.00,3.00)days vs.4.00(4.00,4.00)days,P<0.001],and lower hospitalization costs[17 028.00(15 178.05,17 934.50)RMB vs.20 653.00(19 176.25,22 630.00)RMB,P<0.001]compared with Group B.There was no significant difference in SFR between groups(P>0.05).Conclusion For patients with upper urinary tract stones and renal pelvic separation>10 mm,NR-ST-PCNL performed by experienced surgeons achieves comparable stone clearance to conventional techniques while reducing complication risk,shortening operative and hospitalization times,and lowering costs.It represents a safe,efficient,and optimized clinical approach.
