Interpreting the fractional excretion of sodium

American Journal of Medicine, 1984
In most normal subjects, the fractional excretion of sodium is usually less than 1 percent but may be raised with an increase in salt intake. In acutely azotemic patients, a low fractional excretion of sodium usually indicates a prerenal process that is responsive to volume repletion.

Influence of volume expansion, serum sodium, and fractional excretion of sodium on urate excretion

Pflugers Archiv European Journal of Physiology, 1975
The relative contributions of volume expansion and increased fractional excretion of sodium to the uricosuria of saline infusion were assessed in 19 subjects by volume expansion with rapid infusion of 21 of hypertonic saline (3%), isotonic saline (0.9%), or hypotonic saline (0.45%).

Diagnostic Performance of Fractional Excretion of Urea and Fractional Excretion of Sodium in the Evaluations of Patients With Acute Kidney Injury With or Without Diuretic Treatment

American Journal of Kidney Diseases, 2007
The accuracy of fractional excretion of sodium (FENa) for the diagnosis of transient acute kidney injury (AKI) caused by decreased kidney perfusion is reported to be low in patients administered diuretics.This is a prospective study of diagnostic accuracy comparing the performance of fractional excretion of urea (FEur) with that of FENa to distinguish ...

Fractional Excretion of Sodium (FENa) [Updated]

Evidence to Action: Official Journal of MDCalc
Fractional Excretion of Sodium (FENa) quantifies the proportion of filtered sodium that is excreted in the urine and is widely used to help distinguish between different causes of acute kidney injury (AKI), particularly in oliguric patients. FENa provides a more reliable measure of renal sodium handling than urine sodium concentration alone, as it ...
