Retrograde cystography

Retrograde cystography is a detailed x-ray examination of the bladder, in which contrast dye is placed into the bladder through the urethra. The urethra is the tube that carries urine from the bladder to the outside of the body.

Cystography - retrograde

You will lie down on the table. A a flexible tube (catheter) is inserted into your bladder after an anesthetic jelly has been applied. The contrast dye flows through the catheter until your bladder is full. Inform the technician when your bladder feels full.

When the bladder is full, you are placed in different positions for various x-ray pictures of the full bladder. After the catheter is removed and you have been given the opportunity to urinate, one more x-ray is taken to see how well the bladder has emptied. The total test time is about 30 - 60 minutes.

You must sign an informed consent form. You must empty your bladder before the test. A medical history will be taken to determine if you may have an allergic reaction to the contrast dye, or if there is a current infection that could make the catheter insertion difficult.

When the catheter is inserted, there may be some pressure along the urethra. When the dye first begins to enter the bladder, an urge to urinate occurs. The technologist will stop the flow when the pressure becomes uncomfortable. The urge to urinate will continue throughout the test.

After the test, the urethra may be tender during urination.
