Aside from a minor sting from the injection of contrast material, an IVP causes no pain. When the contrast material is injected, some people report feeling a flush of heat and, sometimes, a metallic taste in the mouth. These common side effects usually disappear within a minute or two and are no cause for alarm. Some people experience a mild itching sensation. If it persists or is accompanied by hives, the itch can be treated easily with medication. In rare cases, a patient may become short of breath or experience swelling in the throat or other parts of the body. These can be indications of a more serious reaction to the contrast material that should be treated promptly, so tell the radiologist immediately if you experience these symptoms.
During the imaging process, you may be asked to turn from side to side and to hold several different positions, to enable the radiologist to capture views from several angles. Near the end of the exam, you may be asked to empty your bladder so that an additional film can be taken of your urinary bladder after it empties.
The contrast material used for IVP studies will not discolor your urine or cause any discomfort when you urinate. If you experience such symptoms after your IVP exam, they are likely to indicate some other problem. Let your doctor know right away.
