This is usually marked by elevations in serum creatinine and increased, normal, or decreased urine output. The terms polyuria, oliguria, and anuria sometimes are used to characterize the type of failure. The term acute kidney injury (AKI) has replaced acute renal failure in the literature in an effort to better characterize the spectrum of impairment in renal function before complete failure.
