Methods：Aretrospectiveanalysiswasconstructedon29childrenwithunilateralureteropelvicjunctionobstruction（UPJO）and SFUgradeIVhydronephrosiswhounderwentlaparoscopicpyeloplasty.29casesweredividedintoahighratiogroup（4cases， APD/PT ≥15）and a low-ratio group （15 cases，APD/PT <15 ）.The improvement in differential renal function （△DRF）after surgerywas comparedbetween the two groups.Results：The high-ratio group had a significantlylower ΔDRF than the low-ratio group ⌊（4.12±5.87）% vs. （9.78±7.23）%，P=0.021. 1.Preoperative APD/PT was negatively correlated with △DRF（ r= -0.451，P=0.014 ）and was an independent predictor for DRF improvement （OR=1.28，95%CI 1.09-1.51， P =0.009）. Conclusions： ThepreoperativeAPD/PTisareliablepredictorofrenalfunctionrecoveryfolowinglaparoscopicpyeloplastyinchildren withseverehydronephrosis．PatientswithanAPD/PT≥15experiencepoorerrecovery.Thissimple，non-invasivemetricis recommended for inclusion in preoperative assessments.
