Postoperative Neutrophil Gelatinase–Associated Lipocalin Predicts Acute Kidney Injury After Pediatric Cardiac Surgery*

Abstract

Urine neutrophil gelatinase-associated lipocalin is a predictive biomarker for acute kidney injury after pediatric cardiac surgery, and it may permit earlier intervention that improves outcome of acute kidney injury. Urine neutrophil gelatinase-associated lipocalin normalized to urine creatinine improves the prediction of acute kidney injury severity but offers no advantage in acute kidney injury diagnosis.
