WebThe Fractional Excretion of Urea (FEUrea) determines the cause of renal failure. Similar to the FENa, but can be used on patients on diuretics. While the above values are useful for older children and adults, the FENa must be interpreted more cautiously in younger pediatric patients due to the limited ability of immature tubules to reabsorb sodium maximally. Thus, in term neonates, a FENa of <3% represents volume depletion, and a FENa as high as 4% may represent maximal sodium conservation in critically ill preterm neonates. The FENa may also be spuriously elevated in children with adrenal insufficie…

WebSimilarly, the finding of a high urine sodium or high FENa is not diagnostic of ATN because this can be present in the setting of high sodium intake without AKI, in diuretic use, and with resolution of AKI or resolution of kidney obstruction (42).

WebBackground: Fractional excretion of sodium (FENa) has been used in the diagnosis of acute renal failure (ARF) to distinguish between the two main causes of ARF, prerenal state and acute tubular necrosis (ATN). However, many patients with prerenal disorders receive diuretics, which decrease sodium reabsorption and thus increase FENa. pho 999 oshawa menu
