Some kidneys don t empty at the same rate and delayed films from thirty minutes to three or four hours may be requested. However, a typical IVP study usually takes about an hour. Aside from the minor sting from the injection of contrast agent, an IVP causes no pain. When the contrast agent 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 agent 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 as it empties.
