What Are the Risks and Complications of a Kidney Biopsy?

While a kidney biopsy is generally safe, it carries some risks and potential complications, including:

  • Bleeding: Mild bleeding is common, but severe bleeding requiring a blood transfusion or surgery is rare.
  • Infection: There is a risk of infection at the biopsy site.
  • Pain: Some patients may experience pain or discomfort at the biopsy site, which can usually be managed with pain medications.
  • Damage to Nearby Organs: Although rare, there is a risk that the biopsy needle could damage surrounding organs or tissues.

Hematoma: A localized collection of blood (hematoma) can form around the kidney, causing pain and swelling.
