The intravenous pyelogram is usually a relatively comfortable procedure. You will feel a minor sting when the small needle is inserted into the vein. When the contrast agent is injected, you may feel flushing throughout your body, bitter taste in the throat or a bad smell from the contrast agent. These common side effects usually disappear within a few minutes.
During the imaging process, you will be asked to turn from side to side and to hold several different positions and hold your breath for clarity images.
At the end of the intravenous pyelogram exam, the film of your full-filled bladder will be taken and you will be asked to empty your bladder before the last film is taken.
