Definition of Acute tubular necrosis. Acute tubular necrosis: A severe form of acute renal failure that develops in people with severe illnesses (such as sepsis) or with very low blood pressure. Patients may need dialysis. Kidney function often improves if the underlying disease is successfully treated. Abbreviated ATN.
Intrinsic renal causes are also important sources of acute. kidney injury and can be categorized by the component. of the kidney that is primarily affected (i.e., tubular, glo -. merular, interstitial, or vascular). Acute tubular necrosis is the most common type of. intrinsic acute kidney injury in hospitalized patients. The cause is usually ischemic (from prolonged hypoten-. sion) or nephrotoxic (from an agent that is toxic to the. tubular cells).
