Discharge Instructions for Kidney Biopsy

You had a procedure called a kidney biopsy. Your doctor used a special needle to remove a small piece of tissue from your kidney to examine it for signs of damage and disease. A kidney biopsy is ordered after other tests have shown that there may be a problem with your kidney. Kidney biopsies are also performed when kidney disease is suspected and to rule out cancer.

Home care

  • Rest for 24 hours to 48 hours. Get up only to use the bathroom.

  • Don’t drive for 24 hours to 48 hours after the procedure.

  • Don’t shower for 24 hours after the biopsy. If you wish, you may wash yourself with a sponge or washcloth. When you are able to shower, don’t scrub the site. Gently wash the area and pat it dry.

  • Remove the bandage covering the biopsy site 24 hours to 48 hours after the procedure.

  • Don’t lift anything heavier than 10 pounds for 3 days to 4 days after the procedure.

  • Ask your doctor when you can return to work. Be sure to tell your doctor if your job involves heavy lifting.

  • If you normally take blood thinner medications (anticoagulants or antiplatelet medications) and you stopped taking them a few days before your procedure, ask your doctor when to start taking them again.
