What happens in a kidney biopsy?

If your doctor suspects you might have kidney disease or damage, he or she may perform a biopsy of your kidney.

During a biopsy a doctor removes a small sample of your kidney tissue to examine under a microscope, according to the Mayo Clinic.

The Mayo Clinic states that biopsies are typically conducted by inserting a thin needle into the patient's skin to obtain the tissue sample. According to the Mayo Clinic, doctors usually use an imaging device to help guide the needle.

Once the tissue sample is obtained, doctors will carefully examine it under a microscope to look for signs of damage or disease.
