Intravenous pyelogram

What is an intravenous pyelogram?

An intravenous pyelogram (IVP) is an X-ray examination of the urinary tract, including the kidneys, ureters and bladder.  This procedure occurs when patients experience pain in the kidney area when blood is found in the urine or if the doctor suspects a kidney stone, tumour or injury.  A contrast medium will be used to visualise these soft tissue structures.  The radiographer will ask you about your medical history and any known allergies to medications or food (especially iodine).  The procedure usually takes about one hour.

What preparation is needed?

For an IVP to be successful, your intestines must be empty. The receptionist will explain the instructions for the preparation below when you receive the preparation.  Prescribed medication may be taken before the examination.  If you are a woman of childbearing age and there is a possibility that you are pregnant, be sure to inform us before you start the preparation.

You will be sent for blood tests (U&E) before the examination day.  We need to know your renal function before continuing the examination.

What happens during the examination?

Before your IVP, a radiographer will explain the procedure and answer any questions.  You will be asked to remove your clothing and put on a gown.  You will be positioned on the x-ray table with the x-ray equipment above you.  An x-ray will be taken before receiving the IV-contrast medium to ensure your intestines are empty.  The contrast medium, which makes your urinary system visible on radiographic images, will be injected into a vein in your arm.  As it passes through your bloodstream into your urinary system, you may notice a metallic taste or a wave of nausea in your mouth.  These are normal reactions and usually will disappear within a short time.  Let the radiographer know immediately if you begin to itch or feel short of breath.  Time-delayed X-rays will be taken after the injection as the contrast medium travels through your urinary system.  You may be asked to empty your bladder near the end of the examination, and another x-ray may be taken.

After this procedure, you may resume normal activities. However, you must drink plenty of fluids to flush the kidneys.

What about the result?

Once the examination is completed, the X-rays will be studied by the radiologist and compared to any previous X-rays of the same area taken previously.  A typed report of the findings will be completed and forwarded to your doctor.  Please contact your doctor for the results.  This procedure may be changed to a CT urogram at the radiologist's discretion.
