Intravenous urogram (IVU)

An Intravenous Urogram (IVU), is a radiological procedure that uses a contrast dye injected into a vein to visualise the kidneys, ureters, and bladder on X-ray images, aiding in the diagnosis of conditions affecting the urinary tract.

An Intravenous Urogram (IVU), also known as an intravenous pyelogram (IVP) demonstrates the "renal tract".

The renal tract is made up of the kidneys, the ureters which are the tubes between the kidneys and bladder, and the bladder. 

You might need an IVU to diagnose conditions such as kidney stones, urinary tract obstructions, tumors, or other abnormalities in the kidneys, ureters, or bladder, as it provides detailed images of these structures using contrast dye and X-ray imaging.

How do I prepare for an IVU procedure? keyboard_arrow_down

You will not be able to eat or drink for three hours prior to this test.

If you have had a previous IVU, abdomen x-ray, kidney ultrasound or CT please bring your films and/or report with you.

Female patients should inform medical staff if they are pregnant or suspect they might be.

Who performs the procedure? keyboard_arrow_down

A radiologist (a doctor) and a radiographer (an x-ray technician) will be present during the procedure. They will explain the process, so feel free to ask any questions if you're unsure.

What happens during the procedure? keyboard_arrow_down

Just prior to the examination

At the start you will be asked to undress, only leaving on your underpants and singlet. The Radiographer (x-ray technician) will give you a gown to wear (like a big T shirt).

This examination requires you to have an injection of a contrast medium. Prior to the examination, we will give you information on contrast media and will ask you to sign a consent. If you have any questions, please discuss these with the Radiographer and / or Radiologist.

The contrast fluid is opaque to x-rays; is concentrated in the kidneys, and goes into the bladder before being passed out with urine. It is colourless, so you cannot see it when you go to the toilet.

Shortly after the injection, some people report feeling a warm flush, and sometimes have a metallic taste in their mouth. These usually disappear within a minute or two, and are no cause for alarm. Should you become itchy or short of breath, let the Radiologist know straight away, as you may have a slight reaction to the contrast and need to have some antihistamine.

If you have asthma or severe allergies, the Radiologist may suggest you take a steroid, or use other imaging options. The Radiologist will discuss this with you and your Doctor. 

During the procedure

You will lie on an x-ray table where the Radiographer will take a image of your abdomen. These images are to see if any stones are shown anywhere in the renal tract.

The Radiologist will then give you an injection in your arm. After this injection, a series of images will be taken over the next 30 minutes as the dye passes through your renal tract. At one stage, a tight band may be placed on your lower abdomen. This helps us to obtain maximum filling with the contrast medium, and thus better detail of the kidneys.

At the end of the examination, you will be asked to empty your bladder and another image taken to see the empty bladder.

How long does an IVU take? keyboard_arrow_down

The test usually takes between 30 and 60 minutes.

What happens after the procedure is completed? keyboard_arrow_down

After the Radiologist has seen your x-rays and the test is completed, you may go home. 

You can eat and drink normally. 

The contrast media is passed out of the body very quickly, and you will not notice it in your urine.

The Radiologist will review the images and provide a written report to your referring doctor.
