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.
Complications of Acute Tubular Necrosis. Specific imbalances vary with the phase of illness; during oliguria, salt and water retention often leads to hypertension, edema, and heart failure. The polyuric phase of ATN may lead to hypovolemia and create a setting for prerenal azotemia and perpetuation of ATN.
