Cystography - retrogradeDefinition Return to top
Retrograde cystography is a detailed X-ray examination of the bladder in which contrast dye is placed into the bladder through the urethra.How the test is performed Return to top
You are positioned lying down on the table. A urinary catheter is inserted into your bladder after an anesthetic jelly has been applied. The dye flows through the catheter until your bladder is full (you inform the technician when your bladder feels full).
When the bladder is full, you are placed in different positions for various radiographs of the distended 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 to 60 minutes.
How to prepare for the test Return to top
You must sign an informed consent form. You must void (empty) your bladder before the test. A 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.How the test will feel Return to top
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.Why the test is performed Return to top
