Fractional Excretion of Sodium (FENa) - MDCalc
The Fractional Excretion of Sodium (FENa) determines if renal failure is due to pre-renal, intrinsic, or post-renal pathology.
Fractional excretion of sodium - Wikipedia
The fractional excretion of sodium (FENa) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
Fractional excretion of sodium, urea, and other molecules in acute ...
Nov 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).
Fractional excretion of sodium - MedlinePlus
Fractional excretion of sodium. Fractional excretion of sodium is the amount of salt (sodium) that leaves the body through urine compared to the amount filtered and reabsorbed by the kidney. Fractional excretion of sodium (FENa) is not a test.
Fractional Excretion of Sodium (FENa) - PubMed Central (PMC)
FENa has traditionally been considered as lacking validity in patients on diuretics. In this study, FENa (>1%) had a specificity of just 54% in detecting intrinsic kidney injury.
Interpretation of the Fractional Excretion of Sodium in the …
The fractional excretion of sodium (FeNa) may be helpful in establishing the cause of acute renal failure. This study was performed to determine the influence of the glomerular filtration rate (GFR), sodium intake, and tubular function on FeNa in children without renal failure.
