The fractional excretion of urea nitrogen (FEUN) is less influenced by furosemide, which inhibits sodium and chloride reabsorption at the thick ascending loop of Henle. In adults, FEUN has been shown to be a useful biomarker in the differential diagnosis of prerenal AKI and ATN, especially in patients receiving diuretic therapy.
