Utility of fractional excretion of urea in the differential diagnosis ...
TīmeklisBackground: 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. TīmeklisFractional excretion of filtered sodium (FENa) is typically elevated (>3%) in acute tubular necrosis and decreased (< 1 %) with volume depletion. We describe a patient who … cloudstratus reviews

TīmeklisThe fractional excretion of filtered sodium (FENa) has been demonstrated to be a reliably discriminating test between prerenal azotemia and acute tubular necrosis. However, with increasing clinical use of the FENa, numerous reports of low FENa (less than 1%) have appeared. c3030wr-f-2x10p
