ATN -->
acute tubular necrosis
medical dictionary

<nephrology> A kidney disorder that results in damage to the renal tubule cells leading to acute renal failure. Acute tubular necrosis can result from any condition which deprives the kidney of oxygen (ischaemia).

Acute tubular necrosis may occur as a complication of shock, trauma or sepsis. Conditions such as diabetes or liver disease can predispose people to the development of acute tubular necrosis. Certain medications (for example aminoglycosides, amphotericin B, cyclosporine) are known to cause acute tubular necrosis as a toxic side effect. Radiopaque contrast dyes, used in some radiologic procedures, may also result in acute tubular necrosis as a rare complication from contrast dye use.
