Definition
Acute renal failure (ARF) was in the past the general term for the condition described now as acute kidney injury(AKI). At present, it is used by some authors to define AKI patients who are treated with renal replacement therapy (RRT), in other words, the most severe stage of AKI.
AKI is defined by a generic definition as an abrupt and sustained decrease in renal function resulting in retention of nitrogenous (urea and creatinine) and nonnitrogenous waste products [1]. Although this definition adequately describes the condition of AKI, it leaves much room for interpretation. What is the exact definition for the crucial words abrupt, sustained, and decrease of renal function? A more precise and practical definition for AKI is offered by the Risk Injury Failure Loss and End stage renal disease (RIFLE)...
