Cystourethrogram: Risks

Content provided by Healthwise

Risks

A cystourethrogram does not usually cause problems. Occasionally this test may lead to a urinary tract infection. If the contrast material is injected with too much pressure, there is some chance of damage to the bladder or urethra.

There is always a slight chance of damage to cells or tissue from radiation, including the low levels of radiation used for this test. However, the chance of damage from the X-rays is usually very low compared with the benefits of the test.

Some people may have an allergic reaction to the contrast material.

After the procedure

It is normal for your urine to have a pinkish tinge for 1 to 2 days after the test. Contact your doctor immediately if you have:

• Blood in your urine after 2 days.
• Lower belly pain.
• Signs of a urinary tract infection. These signs include:
  • Pain or burning upon urination.
  • An urge to urinate frequently, but usually passing only small amounts of urine.
  • Dribbling or leaking of urine.
  • Urine that is reddish or pinkish, foul-smelling, or cloudy.
  • Pain in the back just below the rib cage on one side of the body (flank pain).
  • Fever or chills.
  • Nausea or vomiting.
