BACKGROUND It is possible that this condition will lead to urosepsis and progressive deterioration of renal function in the absence of surgical *** recent clinical studies have shown that multi-tract percutaneous nephrolithotomy(MPCNL)has a similar stone free rate(SFR)as standard percutaneous nephrolithotomy(S-PCNL).As a result,M-PCNL was also recommended as a treatment option for staghorn *** To examine the perioperative and long-term results of ultrasonography-guided single-and *** This was a retrospective cohort *** March 2021 and January 2022,the urology department of our hospital selected patients for the treatment of staghorn calculi using percutaneous *** primary outcomes were com plication rate and SFR,and the characteristics of patients,operative parameters,laboratory measurements were also *** In total,345 patients were enrolled in the study(186 in the S-PCNL group and 159 in the M-PCNL group).The SFR in the M-PCNL group was significantly higher than that in the S-PCNL group(P=0.033).Moreover,the incidence rates of hydrothorax(P=0.03)and postoperative infection(P=0.012)were higher in the M-PCNL group than in the S-PCNL *** regression analysis demonstrated that post-operative white blood cell count(OR=2.57,95%CI:1.90-3.47,P<0.001)and stone size(OR=1.59,95%CI:1.27-2.00,P<0.001)were associated with a higher overall complication rate in the S-PCNL *** mass index(OR=1.22,95%CI:1.06-1.40,P=0.004)and stone size(OR=1.70,95%CI:1.35-2.15,P<0.001)were associated with increased overall complications in the M-PCNL *** Multiple access tracts can facilitate higher SFR while slightly increasing the incidence of acceptable complications.
