Ultilising FE-urea for differentiating types of AKI

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.
Current issue of Pediatric Nephrology has an excellent paper on FE-urea vs FENa in children with AKI, and finding the etiology.
