Association between Increases in Urinary Neutrophil Gelatinase–associated Lipocalin and Acute Renal Dysfunction after Adult Cardiac Surgery

Patients developing postoperative ARD had significantly higher urinary NGAL concentrations early after cardiac surgery. Urinary NGAL may therefore be a useful early biomarker of ARD after cardiac surgery. These findings may facilitate the early detection of acute renal injury and potentially prevent progression to acute renal failure.
