Kidney Biopsy

There is a small chance for serious problems from a kidney biopsy, but they are rare.

• Bleeding into the muscle, which can cause soreness.
• Bleeding into the kidney.
• Infection of the skin at the biopsy site.
• Pneumothorax (collapsed lung).
• Puncturing a major blood vessel, which may need blood transfusions, renal angiography and embolization, or surgery. This is very rare.
