Acute tubular necrosis is damage to the tubule cells (tiny tube-shaped cells) in the kidney that results in acute kidney failure. This is a potentially serious condition that requires medical care.

Acute tubular necrosis can be caused by:
Lack of oxygen to kidney tissues from problems such as
surgical complications, severe dehydration, or heavy bleedingExposure to toxic materials such as antibiotics, x-ray dyes, or anesthetics
Factors that may increase your chance of acute tubular necrosis include: InjuryTraumaSurgeryBlood transfusionSeptic shockShockLow blood pressureLiver disease or damageCertain medications, such as aminoglycosides, amphotericin B, cyclosporine, or tacrolimusX-ray dye
Blood transfusion reaction
Exposure or build up of toxic chemicals, such as:
Crystals (uric acid, calcium phosphate)MyoglobinHemoglobin
Acute tubular necrosis may cause:
Change in urine output
General swelling, fluid retention
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
Blood testsUrine tests
Imaging tests evaluate the kidneys and surrounding structures. These may include:
UltrasoundCT scanMRI scan
Talk with your doctor about the best treatment plan for you. Treatment will focus on treating the conditions that are causing damage. Good nutrition and proper fluid intake will also help reduce stress on the kidneys during recovery. Treatment options may also include:
Dialysis is a process that uses a machine to assist or take over the work of your kidneys. The blood flows from catheters to a machine that removes wastes and returns it back to the body.
Certain medications may reduce the need for
in some people.
Acute tubular necrosis is sometimes the result of an accident. If you have kidney disease or a history of kidney problems, follow your doctor's instructions after surgical procedures or imaging test that required contrast dyes.
