How To Prepare continued...
This test is often done in children to see if they may have an abnormal backflow of urine (vesicoureteral reflux). Prepare your child for exams and tests that are needed by explaining them in a simple way. Use positive words as much as possible. Doing so will help your child understand what to expect and can help reduce fears.
You may be asked to sign a consent form that says you understand the risks of the test and agree to have it done.
Talk to your doctor about any concerns you have regarding the need
for the test, its risks, how it will be done, or what the results may mean. To
help you understand the importance of this test, fill out the
medical test information form(What is a PDF document?).
How It Is Done
A cystourethrogram is done by a
urologist or a
radiologist. The doctor may be assisted by an X-ray
technologist. You usually will not have to be admitted to the hospital.
You will need to take off all or most of your clothes, and you will be
given a cloth or paper covering to use during the test. You will be asked to
urinate just before the test begins.
You will be asked to lie on
your back on an X-ray table. Your genital area will be cleaned and draped with
sterile towels. Men may be given a lead shield that covers their genitals to
protect them from radiation. But women's
ovaries cannot be shielded without blocking the view
of the bladder.
A catheter will be placed through your urethra
and into your bladder. Contrast material will then slowly be injected through
the catheter until your bladder is full.
X-rays will be taken
when you are standing up and sitting and lying down. The catheter is removed
and more X-rays will be taken while you are urinating. You may be asked to stop
urinating, change positions, and begin urinating again. If you are unable to
urinate in one position, you may be asked to try it from another
This test usually takes 30 to 45 minutes.
