What are genitourinary tests?
Genitourinary tests are X-ray studies of the organs of the genitourinary
system: the kidneys, ureters, bladder, and urethra. Genitourinary tests are
performed to look for blockage, injury, or other abnormalities in these organs.
There are several types of genitourinary tests: intravenous urography (also
called an intravenous pyelography or IVP), cystography, and voiding
cystourethrography (VCU).
In Intravenous pyelography, contrast material injected
through the arm filters through the bloodstream and eventually to the
kidneys, through the ureters and into the bladder. A series of
x-rays is taken as the filtering occurs. In cystography, the
contrast material is injected through a catheter inserted through the
urethra and into the bladder, and x-rays are taken. |  |
Before the test
No special preparation is necessary for cystography or voiding
cystourethrography.
- If you are scheduled for intravenous pyelography, you will have
to drink one bottle (30 ounces) of Citrate of Magnesia between 4 p.m. and 6
p.m. the day before the test. Citrate of Magnesia is a laxative that is
taken to remove any intestinal gas or feces that might obscure the X-ray
image.
- Do not eat or drink anything from 10 p.m. the night before the
test until after the test is complete. However, you may take your
usual medications with a small amount of water. Exception: Do not
take Lasix or other diuretics (water pills).
- If you have diabetes and take insulin, we try to have your will
make every effort possible totest scheduled your test early in the day.
- If you have any questions about how to prepare for your test,
please call the radiologist.
On the day of the test
Please do not bring valuables such as jewelry or credit cards.
- The test is performed and the results are reviewed by
registered, licensed technologists and board-certified radiologists.
- Most genitourinary tests take about 1 hour.
- You will empty your bladder, and you will be asked to change
into a hospital gown.
During the test
Intravenous pyelography
A contrast solution will be introduced gradually into your vein
(intravenously). The contrast solution enables the radiologist to visualize the
genitourinary organs on X-ray films.
You may feel a slight tingling or warmth from the contrast material. As the
kidneys filter the contrast material and it moves into your bladder, a series of
X-ray pictures will be taken.
Cystourethrography
A catheter (long, slender tube) will be inserted into your bladder. This may
cause some discomfort. When the catheter is in place, contrast solution will be
injected through the catheter and a series of X-ray pictures will be taken.
After the test
Generally, you can resume your usual activities and normal diet immediately.
