After Your Child’s Kidney (Renal) Biopsy

We expect that your child may have some pain after a kidney (renal) biopsy. This is normal. The pain is most often a soreness rather than severe pain. For the pain we suggest acetaminophen (Tylenol®). The pain should not be severe and should improve daily.

Avoid aspirin or ibuprofen for 2 weeks due to an increased risk of bleeding with these products.

Avoid any activity where your child may be hit in the back by a ball or a person for 7-10 days. Also avoid horseback riding, jumping on a trampoline, or anything that jars or strains the back, such as snow shoveling.

You should call us for these signs.

  • Severe pain or pain that is getting worse

  • Blood in the urine you can see

  • Pain or burning during urination 

  • Fever of 100° F or higher

  • Any other concerns you may have

The biopsy often takes 3-5 business days to fully process. We will call you with the results to discuss treatment and follow-up care.
