What is an Intravenous Pyelogram?

An intravenous pyelogram is a special x-ray of the urinary tract, which includes kidneys, ureters, and bladder. Because x-rays can only detect bony structures of the body, a contrast medium or dye is given intravenously to outline the image of soft tissues. As the contrast travels through the bloodstream, it passes through the kidneys, ureters, and bladder making it possible to take x-ray films of these organs.

Precautions

Let us know if you think you may be pregnant.

Procedure

You will be asked to change into a gown before moving to the x-ray room. You will be asked to lie on a table and a preliminary x-ray will be taken. Next, the contrast will be injected into a vein in your arm. This may cause you to feel warm or you may experience a metallic taste in your mouth. If you experience shortness of breath or feel itchy, let the technologist know immediately.

After the contrast has had a chance to move through your body, you will be asked to change positions and hold still as x-rays are taken. Some examinations may require a full bladder as well as an empty one so you may be asked to empty your bladder at some point during the examination.

After the x-rays have been taken, you will be asked to wait as the radiologist checks the films to make sure enough images have been taken. On occasion, you may be asked to return later for a delayed follow-up x-ray.

Post Exam

You may resume your normal diet and activities as soon as the examination is completed. The contrast will be naturally eliminated from your body and should not discolor stools or urine.

The radiologist will interpret the study and will dictate a report for your doctor. Your doctor will discuss the results with you.
