to empty your digestive system. This is because stool in the intestines may make it harder to read the x-rays.
Do not eat or drink after midnight.
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.
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.
