Acute Tubular Necrosis

Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys. ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI.

Depending on the severity of the initial insult, time to renal recovery can often be prolonged and patients may require dialysis for months.

  • Treatment
  • Intravenous furosemide or bumetanide in a single high dose (ie, 100-200 mg of furosemide) is commonly used, although little evidence indicates that it changes the course of ATN. The drug should be infused slowly because high doses can lead to hearing loss. If no response occurs, the treatment should be discontinued.
  • Recommended specialist
  • If you have Acute Tubular Necrosis, then a visit to a general internist is recommended.
