Preparing Your Child for a Kidney (Renal) Biopsy
Your child is scheduled to have a kidney
(renal) biopsy on _____ at __________
with Dr. _______________________. The
biopsy is being done to figure out the cause
of your child's kidney problem. This helps
us decide what the best treatment for the
kidney disease is. These guidelines help
prepare your child for the biopsy.
Before the Biopsy
Blood tests need to be done to see if
your child has a bleeding problem.
These blood tests are routine before a
biopsy. They are done the morning of
the biopsy. You may be able to have
the lab work done at your local
clinic/hospital/laboratory a few days
before the biopsy and have your
doctor FAX the results to us. Your
doctor will talk with you about this.
Do not give your child aspirin or any
over-the-counter medicines that may
contain aspirin, ibuprofen or
naproxen for 10 days before the
biopsy. Aspirin or aspirin-like
products can prevent the clotting of
blood. You may give your child
acetaminophen (Tylenol®) if you
need to for any reason.

child's special blanket, pillow, or toy

After the Biopsy
Your child will need to lie in bed for
at least 6 to 8 hours. Your child can
do quiet activities and eat. Your
child will only be able to get up to go
to the bathroom.
Blood pressure and heart rate are
checked by the nurse every so often
after the procedure. This is routine
after a biopsy.
If your child needs to go to the
bathroom, please let the nurse know.
Each urine sample needs to be
looked at and measured. It is
common to see blood in your child’s
urine. Most often this clears within 6
to 12 hours.
As soon as your child is fully awake,
it is ok to have something to drink or
eat. The nurse keeps track of how
much your child is drinking. Please
encourage your child to drink.
