webNov 15, 2022 · INTRODUCTION. The fractional excretion of sodium (FENa) measures the percent of filtered sodium that is excreted in the urine. This calculation is widely used to help differentiate prerenal disease (decreased kidney perfusion) from acute tubular necrosis (ATN) as the cause of acute kidney injury (AKI, formerly called acute renal failure).

FRACTIONAL EXCRETION OF UREA: A SIMPLE TOOL FOR …
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6033653/
webThe aim of this study was to evaluate the diagnostic performance of FEUrea for the differential diagnosis of AKI in patients with cirrhosis and ascites presenting to a tertiary care hospital. Specifically, the ability of FEUrea to distinguish between (1) ATN versus PRA and HRS, and (2) PRA versus HRS type 1 was assessed.

webFeb 1, 2012 · The fractional excretion of urea (FEU) is a useful index for differentiating the main categories of causes of acute kidney injury, ie, prerenal causes and intrinsic causes. It may be used in preference to the more widely used fractional excretion of sodium (FENa) in situations in which the validity of the latter is limited, such as in patients taking a diuretic.
