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.

 You may want to bring along your
child's special blanket, pillow, or toy
for comfort.

 Our Pediatric Sedation Service will
contact you before the biopsy to tell
you when your child can eat and

Biopsy Day
ξ Please bring all medicines your
child will need to take the day of
the biopsy with you. You will be
able to give your child’s own
prescribed medicines the day of
the biopsy.

 Report to the Diagnostic and
Therapy center on the 1st floor of the
American Family Children’s
Hospital. Your child’s blood is
drawn and an IV (intravenous line) is
placed. The IV is placed so that
medicine can be given to make your
child drowsy.

 The nurses and doctors from the
pediatric sedation team will do a
brief history and exam to decide the
best medicine to use.

 The biopsy is done using ultrasound.
You may stay with your child during
the biopsy. There is also a waiting
room if you would rather wait
outside the room.

 The biopsy takes about 30 to 45

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.

 Most children are able to go home or
to the Ronald McDonald House at
the end of the day. A few children
may need to stay overnight.

After Your Child is Home
 If your child goes home or to the
Ronald McDonald House the night
of the biopsy, please have your child
rest for the rest of the evening and

 No heavy exercise, sports, gym class
or heavy lifting for 2 weeks. We will
