Nonoliguric Acute Renal Failure Associated with a Low Fractional Excretion of Sodium
Annals of Internal Medicine, 1982Measurement of the fractional excretion of sodium has been recommended as a useful clinical tool in evaluating acute renal failure. Six patients with nonoliguric acute renal failure had a fractional excretion of sodium less than or equal to 1.0%; these patients had severe liver dysfunction, which suggested a sodium-avid state.

Inadequacy of Fractional Excretion of Sodium Test
Archives of Internal Medicine, 1981To the Editor. —The inadequacy of the fractional excretion of sodium test for differentiating causes of oliguria after radiographic contrast infusion as pointed out by Fang et al in the AprilArchives(1980;140:531-533) has important clinical implications.

Low Fractional Excretion of Sodium in Myoglobinuric Renal Failure
Archives of Internal Medicine, 1982• Two patients with rhabdomyolysis had a low fractional excretion of sodium (FENa) that was verified repeatedly during the oliguric phase of established myoglobinuric renal failure. Volume depletion was ruled out in the first patient by lack of response to a volume challenge and in the second patient by direct hemodynamic monitoring.

Fractional excretion of sodium. Exceptions to its diagnostic value.
Archives of internal medicine, 1985Determining the cause of acutely deteriorating renal function is a common problem in clinical nephrology. The fractional excretion of filtered sodium (FENa) has been demonstrated to be a reliably discriminating test between prerenal azotemia and acute tubular necrosis.

Inadequacy of Fractional Excretion of Sodium Test-Reply
Archives of Internal Medicine, 1981We were interested to see the low fractional excretion of sodium and the high urine-to-plasma ratio of creatinine in the patient with acute renal failure after contrast studies described by D'Elia et al. We concur that these urinary indices can be deceiving and can lead to inappropriate and hazardous fluid volume challenges in patients with oliguria ...

Fractional Excretion of Sodium in Acute Renal Failure
Archives of Internal Medicine, 1981To the Editor. —In the April 1980Archives(140;531-533), Fang et al underlined the low fractional excretion of sodium (FE Na ) values that they found in all 12 cases of contrast media-induced acute renal failure; they said this finding is characteristic of contrast media-induced acute renal failure.

Low Fractional Excretion of Urine Sodium in Acute Renal Failure due to Sepsis
Archives of Internal Medicine, 1983A low fractional excretion of sodium (FENa) of less than 1% was present in two patients who had acute renal failure due to sepsis. Both patients had bacteremia and had undergone major abdominal and vascular surgery. Prerenal azotemia due to volume depletion was not present as adequate central filling pressures were maintained with a Swan-Ganz catheter.

Role of Fractional Sodium Excretion in patients with Refractory Hypertension
Zagazig University Medical Journal, 2021Background: Although numerous trials establish reliable profit of dietary sodium (Na+) restriction on blood pressure (BP) control in persons with hypertension; few studies tested the role of fractional sodium excretion “FENa” (a surrogate measure of dietary salt intake) as a predictor of hypertension resistance.
