Complications

By Mayo Clinic staff

If left untreated, a kidney infection can lead to potentially serious complications, such as:

  • Permanent kidney damage. A kidney infection can lead to permanent kidney damage that causes chronic kidney failure.
  • Blood poisoning (septicemia). Your kidneys filter waste from your blood and then return your blood to the rest of your body. If you have a kidney infection, the bacteria can spread as the kidneys return blood to circulation.
  • Pregnancy complications. Women who develop a kidney infection during pregnancy may have an increased risk of delivering low birth weight babies.
