How To Prepare
Tell your health professional if you have had an X-ray with
contrast material (such as barium) within the past 2
days. Barium that remains in the intestines can interfere with the ultrasound
test.
Wear loose clothes for the pelvic ultrasound. You may need to
remove all your clothes below the waist and put on a gown before the
test.
If you are having a biopsy or a special procedure during the
ultrasound, you may need to sign a consent form.
Talk to your health professional about any concerns you have
regarding the need for this test, its risks, how it will be done, or what the
results will indicate. To help you understand the importance of this test, fill
out the
medical test
information form
(What is a PDF document?).
Transabdominal ultrasound
If transabdominal ultrasound is done, your health professional
will ask you to drink 4 to 6 glasses of juice or water about an hour before the
test to fill your bladder. A full bladder pushes the intestines (which contain
air) out of the way of the pelvic organs. This makes the ultrasound picture
clearer. If the ultrasound is being done in an emergency situation, your
bladder may be filled with water through a thin flexible tube (catheter)
inserted into your bladder.
Transrectal ultrasound
If a
transrectal ultrasound is done, you may need an
enema about an hour before the test. Tell your health
professional if you are allergic to latex so that a latex-free cover can be put
on the transducer before it is used.
If a man is having a biopsy of the prostate gland, he may be
given
antibiotics for a day before the test.
Transvaginal ultrasound
If you are having a
transvaginal ultrasound, tell your health professional
if you are allergic to latex so that a latex-free cover can be put on the
transducer before it is used.
If you are having only a transvaginal ultrasound, do not drink
any fluids for 4 hours before the test. You will not need to drink fluids to
fill your bladder for the test as you do in a transabdominal ultrasound.
If both a transabdominal and transvaginal ultrasound will be done,
the transabdominal ultrasound usually will be done first.
