Retrograde cystography is a detailed
Cystography – retrograde; Cystogram
How the test is performed
You lie on the table. A numbing medicine is applied to the opening to your urethra, and a flexible tube (catheter) is inserted through your urethra into the bladder. Contrast dye flows through the tube until your bladder is full or you tell the technician that your bladder feels full.
When the bladder is full, you are placed in different positions so that different x-rays can be taken. A final x-ray is taken once the catheter is removed and you have emptied your bladder. This reveals how well your bladder empties.
The total test takes about 30 – 60 minutes.
How to prepare for the test
You must sign an informed consent form. You must empty your bladder before the test. You will be asked questions to determine if you may have an
How the test will feel
You may feel some pressure when the catheter is inserted. You will feel an urge to urinate when the contrast dye enters the bladder. The person performing the test will stop the flow when the pressure becomes uncomfortable. The urge to urinate will continue throughout the test.
After the test, the area where the catheter was placed may feel sore when you urinate.
Why the test is performed
Your doctor may order this test to:
Examine the bladder for problems such as holes or tears
- Determine if you have:
- Abnormal connections between bladder tissue (bladder fistulae)
- Bladder stones
- Pouch-like sacs called
diverticulaon the walls of the bladder or urethra
- Tumor of the bladder
Urinary tract infection Vesicoureteric reflux
- Learn why you keep having repeated bladder infections
The bladder appears normal.
What abnormal results mean
Bladder stones Blood clots
- Infection or inflammation
- Vesicoureteric reflux
What the risks are
There is some risk of infection from the catheter. Symptoms may include:
- Burning during urination (after the first day)
- Decreased blood pressure (hypotension)
- Increased breathing rate
The amount of radiation exposure is similar to that of other x-rays. As with any radiation exposure, nursing or pregnant women should not usually have this test, unless it is determined that the benefits outweigh the risks.
In males, testicles are shielded from the x-rays.
This test is not performed very often, but is usually combined with CT Scan imaging for better resolution.
