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.
