Ultrasound Guided Biopsy
Your doctor has scheduled a biopsy to be done on________. Please report to the
Radiology (G3/3) on the 3rd floor at ________. Before the biopsy, our doctors will
explain what will happen, answer any questions, and ask you to sign a consent form.
What is a Transrectal Ultrasound
A transrectal ultrasound guided biopsy is
done using an ultrasound probe placed in
the rectum. The probe is covered with a
condom and gel that sends out sound
waves. This produces an image of the
structures in your body onto a TV like
screen creating a picture. The probe will
guide the doctor to the area of concern.
You are asked to lie on your side. The
area of concern will be looked at with
the rectal probe. Local anesthesia will be
injected into the area to biopsy to
prevent pain during the biopsy.
How to Prepare for the Biopsy
ξ You are prepared for your
procedure in our prep and recovery
area before your biopsy. We 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 test. 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®, 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 discuss how your
medicine 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 70mg/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
Midazolam and Fentanyl
medicines in your IV to help
mildly sedate you before the
procedure. 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.
ξ You are asked to take an antibiotic
1 hour prior to the procedure. This
is to prevent infection. Two more
doses are required at 12 hours and
24 hours after the procedure. You
are either given a prescription for
this medication or it will be called
into your pharmacy.
During the Biopsy
Be sure to tell the radiologists if you
have any allergies (medicines,
antibiotics, anesthetic agents, etc.)
An IV will be used to give you IV fluids.
Using the transrectal ultrasound for
guidance, the tissue sample is taken out
with a special needle. One to three
samples may be taken. The tissue sample
is then sent for exam under a
