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 position.

After the test is over, drink lots of fluids to help wash the contrast material out of your bladder and to reduce any burning on urination.

This test usually takes 30 to 45 minutes.
