Acute Tubular Necrosis

Definition

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.

Causes

Acute tubular necrosis can be caused by:

  • Lack of oxygen to kidney tissues from problems such as blood clots, surgical complications, severe dehydration, or heavy bleeding
  • Exposure to toxic materials such as antibiotics, x-ray dyes, or anesthetics

Risk Factors

Factors that may increase your chance of acute tubular necrosis include:

  • Injury
  • Trauma
  • Surgery
  • Blood transfusion
  • Septic shock
  • Shock
  • Low blood pressure
  • Liver disease or damage
  • Certain medications, such as aminoglycosides, amphotericin B, cyclosporine, or tacrolimus
  • X-ray dye
  • Blood transfusion reaction
  • Exposure or build up of toxic chemicals, such as:
    • Crystals (uric acid, calcium phosphate)
    • Myoglobin
    • Hemoglobin

Symptoms

Acute tubular necrosis may cause:

  • Change in urine output
  • General swelling, fluid retention
  • Nausea, vomiting
  • Dehydration

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.

Tests may include:

  • Blood tests
  • Urine tests
  • Kidney biopsy

Imaging tests evaluate the kidneys and surrounding structures. These may include:

Treatment

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

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.

Medications

Certain medications may reduce the need for dialysis in some people.

Prevention

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.
