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; Cystogram

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.

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 allergic reaction to the contrast dye, or if you have a current infection that could make inserting the catheter difficult.

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.

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
  • Diverticula
  • Tumor of the bladder
  • Urinary tract infection
  • Vesicoureteric reflux
• Learn why you keep having repeated bladder infections
