ABSTRACT
Objective To evaluate the values of urinary liver-fatty acid binding protein (uL-FABP) and urinary neutrophil gelatinase-associated lipocalin (uNGAL) in diagnosis of acute kidney injury (AKI) caused by obstructive nephropathy and in the prediction of renal prognosis.Methods Clinical data of 30 patients with obstructive nephropathy were collected prospectively.uL-FABP and uNGAL were measured by ELISA at various time points.Risk factors of the renal outcome were evaluated.The patients were followed up for at least one year.Results Patients with AK1 had higher levels of uL-FABP and uNGAL compared to those without AKI [700.00(154.62-1216.14) μg/g· Cr vs 26.90 (16.77-41.38) μg/g·Cr; 1266.69 (671.57-3396.07) μg/g·Cr vs 179.12 (90.98-215.16) μg/g·Cr,all P < 0.01].Positive correlations of uL-FABP and uNGAL with serum creatinine were found (r =0.552,0.553,all P < 0.01).The AUCs of uL-FABP and uNGAL to detect AKI were 0.925 and 0.900.Patients with non complete renal recovery had higher levels of uL-FABP before operation and 72-hour after operation compared to those with complete renal recovery (all P < 0.01).Before operation,the AUC of uL-FABP to detect renal prognosis was 0.948,sensitivity was 85.7% and specificity was 90.9%.72-hour after operation,the AUC of uL-FABP to detect renal prognosis was 0.935,sensitivity was 85.7% and specificity was 90.9%.Kaplan-Meier analysis revealed that uL-FABP before operation over 366.57 μg/g · Cr or uL-FABP 72-hour after operation over 223.60 μg/g · Cr were closely related to the poor progression of renal function.Conclusions uL-FABP and uL-NGAL have good accuracy in detecting AKI.The level of uL-FABP before operation and 72-hour after operation is helpful to predict the renal outcome of obstructive nephropathy.
