risks are there from the test?
- There is a small
chance of having an allergic reaction to the x-ray dye used
in the test. Some patients have some temporary irritation of
their urethra after the tube has been in place, and this might
result in some burning during urination for a few hours afterward.
Let your doctor know if burning or pain with urinating lasts
longer than a day; this could mean you have developed an infection.
As with all x-rays, there is a small exposure to radiation. In
large amounts, exposure to radiation can cause cancers or (in
pregnant women) birth defects. The amount of radiation from x-ray
tests is very small-too small to be likely to cause any harm.
X-rays such as this kind in the pelvic area should be avoided
in pregnant women, because the developing fetus is more sensitive
to the risks from radiation.
