Definition

A cystogram uses contrast material to create images of the:

Bladder
Ureters—tubes that carry urine from the kidneys to the bladder
Urethra—the tube that carries urine from the bladder to the outside of the body

The Urinary Tract

Reasons for Procedure

A cystogram helps your doctor gain more information about the urinary system. For example, if you are having urine leakage, your doctor may be able to find the cause.

A cystogram can also be used to diagnose conditions like:

Vesicoureteral reflux —urine flows from the bladder back towards the kidneys
Bladder distention—enlargement of the bladder
Bladder irregularities, such as bladder cancer and incomplete voiding

Possible Complications

Problems from the test are rare. However, all procedures have some risk. Your doctor will review potential problems, like:

Urinary tract infection due to the catheter being inserted
Bleeding due to the catheter being inserted
Discomfort during urination, which may last several hours
Allergic reaction to the contrast material

Talk to your doctor about these risks before the procedure.

What to Expect

Prior to Procedure

There are no special steps to take before a cystogram. However, it is important that you tell your doctor if you:

Are pregnant or breastfeeding
Have a cold or the flu, or have recently been around people who are sick
Are allergic to contrast material
Take diabetes medication

Description of the Procedure

You will be asked to lie on a table. A catheter will be inserted into the urethra and positioned into the bladder. A contrast material will be inserted through the catheter and into the bladder to fill it. When your bladder is full, x-rays will be taken of the ureters, bladder, and urethra. You will be asked to remain still while the images are taken. You may also need to move into different positions.

If your doctor needs to see how your urethra is functioning, you may be asked to urinate into a bedpan while x-rays are taken. Additional images may be needed after you have emptied your bladder.

The catheter will be removed during the procedure.

How Long Will It Take?

About 1 hour

Will It Hurt?

You may have some discomfort when:

The catheter is placed into the urethra
The contrast material goes into the bladder

Post-procedure Care

At the Care Center

You will be able to go home after the test.

At Home

Call Your Doctor

Call your doctor if any of these occur:

Blood in the urine that lasts longer than expected
Discomfort during urination that lasts longer than expected
Pain
Fever
Inability to urinate

If you think you have an emergency, call for emergency medical services right away.
