Finding the cause of acute kidney injury: Which index of fractional excretion is better?

Cleve Clin J Med. 2012 Feb;79(2):121-6

Abstract
The fractional excretion of urea (FEU) is a useful index for differentiating the main categories of causes of acute kidney injury, ie, prerenal causes and intrinsic causes. It may be used in preference to the more widely used fractional excretion of sodium (FENa) in situations in which the validity of the latter is limited, such as in patients taking a diuretic.
