Detailed explanation-1: -If renal function is truly affected the typical course of AKI includes 4 stages: (I) initiation, (II) oligo-anuria, (III) polyuria, and (IV) restitution. In this dynamic process, clinical signs of renal dysfunction emerge during stage 2 (oligo-anuria).
Detailed explanation-2: -AKI is defined by any of the following: Rise in serum creatinine ≥0.3 mg/dL within 48 hours. Rise in serum creatinine ≥1.5 times baseline, which is known or presumed to have occurred within the prior seven days. Urine output < 0.5 ml/kg/hour for six hours.
Detailed explanation-3: -Acute tubular necrosis is the most common type of intrinsic acute kidney injury in hospitalized patients. The cause is usually ischemic (from prolonged hypotension) or nephrotoxic (from an agent that is toxic to the tubular cells).
