Ultrasound Guided Biopsy
Kidney Mass Biopsy

Your doctor has scheduled a biopsy of an area on one of your kidneys. This will be done on
________________. Please register for the procedure at Radiology G3/3 on the 3rd floor
at___________ am/pm. Before the biopsy, our doctors will explain what will happen, answer
any questions, and ask you to sign a consent form.

What Is a Biopsy Done by Ultrasound?
A biopsy removes a small tissue sample
from the area of concern. The procedure is
guided by the use of ultrasound. Ultrasound
looks at deep structures by making an image
from the sound waves which reflect back
from the tissues. No radiation or “x-ray” is
used.

How to Prepare for the Biopsy
ξ You are prepared for your procedure in
our prep and recovery area before your
biopsy. We will start an IV and take
your blood pressure, pulse,
respirations, and temperature. This
makes sure you are safe to have the
procedure and can be given sedation.
ξ You may have lab tests done on the
day of the procedure. We may draw
blood for a platelet count and INR.
This will be done when your IV is
started or in some instances we may
request this to be done in the lab prior
to registration.
ξ Please tell us if you take blood thinners
such as Coumadin® (warfarin),
Heparin, Plavix®, Pradaxa®,
Ibuprofen, Naproxen, low molecular
heparin injections (Fragmin® or
Lovenox®) or daily aspirin. Someone
from ultrasound will call your doctor
and let you know when you should
stop taking it and when you should
start again.
ξ If you have diabetes, please call your
doctor to talk about how your
medicine doses should change before
this procedure. Test your blood sugar
more often when you can’t eat as well
as before the procedure. If your blood
sugar level is low (less than 70 mg/dl)
or you have symptoms, eat some
glucose tablets or drink 4 ounces of a
clear liquid with sugar. Always
recheck your blood sugar level to make
sure it stays above 70. We may still be
able to do the procedure unless you
need to eat solid food to keep your
blood sugar at a normal level. If the
blood sugar ever gets too high or too
low and you can’t bring it back to
normal, call your local doctor or
diabetes doctor.
ξ Stop eating at ________ the day of
the procedure. You may drink clear
liquids until _______ the day of the
procedure. Clear liquids include
black coffee, tea, water and juices
without pulp that you can see through.
ξ You are awake for the procedure.
You may be given the medicines
Midazolam and Fentanyl in your IV

before the procedure to help mildly
sedate you. Please tell the nurse if
you have sleep apnea. Someone must
drive you home if you receive any
medicines. You should not drive or
make important personal or
business decisions until the next day.

During the Biopsy
Be sure to tell the radiologists if you have
any allergies (medicine, antibiotics,
anesthetic agents, etc.).

An IV will be used to give you fluids.

After a review of your x-rays the radiologist,
uses an ultrasound and marks an area that
shows the best place to insert the needle.
After this, the area is cleaned with special
soap. The skin around the site is numbed so
you will have little pain. Most patients feel
pressure, but not major pain. You may be
positioned on your back, side, or stomach.

Under ultrasound, the tissue sample is taken
out using a special needle. One to three
samples may be taken. The tissue sample is
then sent for exam under the microscope.

After the Biopsy
ξ A bandage is put on the site where the
tissue sample was taken. You will
remain in bed for 2-4 hours. During
this time you are able to get up to use
the bathroom. Call the nurse for help
if you need it. Your pulse, blood
pressure, and biopsy site are checked
often. After 2-4 hours, you will be
able to go home if there are no
problems.
ξ After the local anesthetic wears off,
you may feel some discomfort at the
site. Your pain should not be severe,
but is often described as somewhat
sore. If you have discomfort, use
Tylenol up to 3 times daily. You may
talk to the doctor or nurse if you have
questions about the dose. The pain
should go away within the first 24
hours.
ξ You are not able to eat or drink for 1
hour after the procedure.
ξ Tell the nurse if you have new pain,
nausea, vomiting, or chills.

Your Care at Home
ξ You may eat or drink what you like
once you arrive home. Do not drink
alcohol for the first 24 hours.
ξ Rest and take it easy for the first 24
hours. Do not lift greater than 10
pounds. Resume your normal routine
after 24 hours.
ξ You may remove the bandage over the
site the next morning.
ξ You may shower after 24 hours.

When to Call the Doctor
Call if you have any other questions or
concerns, or if:
ξ You have more than a teaspoon of
bleeding at the site.
ξ You feel dizzy, faint, or light-headed.
ξ Your pain around the site gets worse
rather than better 2-3 days later.
ξ You are not feeling well and have a
fever greater than 100.4 θ F (38 θ C).
ξ Blood in your urine that is worsening
after 2 days.
