Cystourethrogram

A cystourethrogram is an X-ray test that takes pictures of your bladder and urethra camera.gif while your bladder is full and while you are urinating. A thin flexible tube (urinary catheter camera.gif) is inserted through your urethra into your bladder. A liquid material that shows up well on an X-ray picture (contrast material) is injected into your bladder through the catheter, then X-rays are taken with the contrast material in your bladder. More X-rays may be taken while urine flows out of your bladder, in which case the test is called a voiding cystourethrogram (VCUG).

If X-rays are taken while contrast material is being injected into the urethra, the test is called a retrograde cystourethrogram because the contrast material flows into the bladder opposite the usual direction of urine flow.

Why It Is Done

A cystourethrogram is done to:

How To Prepare

Tell your doctor if:

  • You are or might be pregnant.
  • You are breast-feeding. The contrast material used in this test can get into your breast milk. Do not breast-feed your baby for 2 days after this test. During this time, you can give your baby breast milk you stored before the test, or formula. Discard the breast milk you pump for 2 days after the test.
  • You have symptoms of a urinary tract infection, such as pain or burning when you urinate.
  • You are allergic to the iodine dye used in the contrast material or any other substance that contains iodine. Also tell your doctor if you have asthma, are allergic to any medicines, or have ever had a serious allergic reaction (anaphylaxis), such as after being stung by a bee or from eating shellfish.
  • Within the past 4 days, you have had an X-ray test using barium contrast material, such as a barium enema, or have taken a medicine (such as Pepto-Bismol) that contains bismuth. Barium and bismuth can interfere with test results.
  • You have an intrauterine device (IUD) in place.
