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.
What Causes Acute Tubular Necrosis? The most common cause of ATN is a lack of oxygen reaching the cells of the kidney. When blood cannot reach the tissues and cells of the kidneys due to a blockage or restriction, the kidneys can be damaged or destroyed. A heart attack, stroke, and long-standing diabetes can result in reduced blood flow to the kidneys causing cell death and ATN. Harmful substances in the blood can also damage tubules.
