A cystourethrogram is an
X-ray test that takes pictures of your
bladder and urethra while your bladder is full and while you are
urinating. A thin flexible tube (urinary catheter) 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
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.
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.

Within the past 4 days, you have had an X-ray test using barium

Pepto-Bismol) that contains bismuth. Barium and bismuth can interfere with test
