An IVP is most often done in a hospital or a doctor’s office. It is done by an x-ray technician with a doctor’s oversight.
You’ll likely be on a restricted diet 24 hours before to the test. You’ll be asked to urinate right before, to make sure your bladder is empty. Then you’ll be asked to lie on your back and remain still.
An x-ray, also called a "scout" film, will be taken of the abdomen and pelvis before the contrast agent is used. This helps to make sure that the x-ray machine is set for your size, and that there are no small stones present. The contrast agent is then injected into your vein. A series of x-rays are taken to see the contrast material filter through your kidneys. Once the agent has moved through the kidneys, it will pass down the ureters into the bladder. X-rays are taken throughout to follow the path of the contrast agent. The x-rays will be reviewed for evidence of tumors, cysts, stones, or other structural and functional abnormalities.
At the end of the study, you’ll be asked to urinate so that a final set of images can show how well your bladder empties. Once the IVP is over, you can immediately resume your daily activities.
