Fractional Excretion of Sodium (FENa) - MDCalc
WEBThe Fractional Excretion of Sodium (FENa) determines if renal failure is due to pre-renal, intrinsic, or post-renal pathology.
Fractional Excretion of Urea (FEUrea) - MDCalc
WEBThe Fractional Excretion of Urea (FEUrea) determines the cause of renal failure. Similar to the FENa, but can be used on patients on diuretics.

WEBNov 15, 2022 · 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).

WEBJan 20, 2017 · FENa measures the ratio of sodium excreted in the urine compared to how much is filtered through the kidney. A FENa of less than 1% in oliguric patients may indicate prerenal azotemia, as an increased reabsorption of sodium is the appropriate response of functioning nephrons to decreased renal perfusion.
