Kidney Biopsy

• Your child can typically return to school 1 to 2 days after the biopsy.
• Limit activity until the next day and keep activity light for the first week.
• Limit vigorous activity for 3 weeks (no running, jumping, gym class, sports, or rough play).
• Avoid carrying heavy backpacks during this 3-week period.
• Drink plenty of fluids.
• Take pain medication as directed by your doctor.
• It is okay to shower, but no bathing or swimming.
• The dressing can be removed after 48 hours.
• Your child may have some increase in pain after they return home, often caused from the increased activity.

Monday to Friday, call the Nephrology clinic at 206-987-2524 for questions or any of the concerns listed below. Send MyChart messages for non-urgent questions.

Nights, weekends and holidays, call 206-987-2000 and ask the hospital operator for the nephrology fellow on call for urgent concerns from the following list:

• Red or blood in pee (urine)
• Significant pain not relieved by acetaminophen (Tylenol) or needing more than 3 doses
• Unable to tolerate drinking fluids
•  Temperature greater than 101°F (38°C)

The results of your child’s biopsy will not be ready for 7 to 10 days after it is done. Sometimes, early results are ready sooner. We must wait for all the test results before we can give you a diagnosis. There may also be a scheduled clinic visit 1 to 2 weeks after the biopsy to discuss the results.
