Cystography

Cystography (also known as a cystogram) is a type of imaging test that uses X-rays to evaluate the bladder. It may be used in conjunction with cystourethrography, which images both the bladder and the urethra, the tube that carries urine out of the body.

Conditions commonly diagnosed and managed with these forms of imaging include:

• Vesicoureteral reflux (VUR), a condition where urine flows backward from the bladder into the ureters and sometimes the kidneys
• Bladder abnormalities, such as bladder diverticula, tumors or polyps
• Recurrent urinary tract infections, urinary incontinence or blood in the urine
• Blockages or strictures (narrowing) of the urethra or ureters
• Trauma to the bladder

When you arrive for your procedure, a technologist or nurse will greet you, take you to the examination room and ask a series of questions about your health. Please let them know if you think you may be pregnant or have any allergies. You will then change into a hospital gown and go to the bathroom to empty your bladder.

Next, we will help position you on your back on the X-ray table, wash your pubic area and gently insert a catheter into your urethra. Then a radiologist or urologist will slowly fill your bladder with a special dye called a contrast agent through the catheter. You may feel some pressure and fullness, as if you need to urinate.

Once your bladder is full, we will take X-rays, using fluoroscopy, which allows us to assess how your urinary system is functioning in real time. Then the catheter will be removed and you will be able to use the bathroom to empty your bladder.

If you are undergoing a voiding cystourethrogram (VCUG), we will take X-ray images while you urinate into a special urinal to examine the size and shape of the bladder while it empties. Sedation is commonly used during VCUGs to help reduce distress.

• Follow instructions for your appointment. When you make your appointment, our care team will explain your particular procedure and provide detailed instructions. Depending on the type of procedure, you may be asked to limit food and fluid intake for a period of time before the exam.
• Arrange child care and arrive early. For the safety of you and your children, please do not bring them to your appointment. If you are unable to arrange child care, please reschedule your appointment. Arrive 10-15 minutes early to fill out paperwork.

A radiologist, a physician who specializes in interpreting medical imaging, will analyze the results and send a report to your health care provider. You can also view your results in MyChart once they are available.
