For surgical outcomes analysis, no significant difference was detected regarding to WI (P=.58), OT (P=.40),TR (P=.58) and EBL (P=.35) between two groups. The assessment of renal function by creatinine value both at the early postoperative (P=.36) and at last follow-up (P=.38) revealed no difference. There was no significant difference in eGFR (P=.62), and at the early postoperative percentage decrease of eGFR (P=.79). However, a higher percentage decrease of eGFR decrease at last follow-up was demonstrated for the AV clamping group (FE WMD 2.42, P less then .00001). CONCLUSION These results suggest that AO clamping might be a better choice for PN in long term. RCT studies with larger sample numbers, and long term follow-up and split renal function assessment should be conducted in the future to confirm our conclusion.OBJECTIVE To evaluate predictive capability and clinical applicability of the current nephrolithometric scoring systems of S.T.O.N.E. score, Guy's Stone Score, CROES nomogram and S-ReSC score for percutaneous nephrolithotomy outcome in the same cohort in a prospective study. METHODS Consecutive patients undergoing PCNL between 2015 and 2018 were included calculating the four scores in the same cohort. Stone free status, complications, operative time, estimated blood loss, fluoroscopy time and length of hospital stay were investigated. ROC curves for predictive accuracy and regression analysis for predictors of SFS were performed. RESULTS In all, 162 PCNLs were accomplished and analyzed. Overall SFS was 75.9% and complication rate 30.9%. Mean+SE acquisition time of scores were 52.9±0.5 sec for GSS, 05.1±0.3 for STONE score, 224±3.1 for CROES and 102.6±3.5 sec for S-ReSC score. SFS had best association with CROES grade, Clavien grade was found with STONE score and EBL and OT had best associati
