- Do not eat or drink after midnight.
Description of the Test
An IV will be inserted. This will provide the contrast material and any medication that you will need. For the next 30-60 minutes, you will lie on a table while x-rays are taken at regular intervals. You may be asked to hold your breath each time an x-ray is taken. The material will highlight your urinary system on the x-ray. This will allow your doctor to see these body parts at work and detect problems. Before the last x-ray, you will empty your bladder in a bathroom.
You will be able to resume your normal activities and diet.
How Long Will It Take?
About 60-90 minutes
Will It Hurt?
No, but you may feel a sensation of warmth or heat as the contrast material travels through your body.
It may take a few days to receive your test results. Your doctor will discuss the results with you, as well as any recommended treatment.
