IVU - Intravenous Urograms

IVUs are performed in the Radiology department on level B.

An IVU is an investigation which involves injecting a dye into the body via a vein so that the kidneys and urinary system can be visualised, and taking a series of x-rays to show its progress through the urinary tract.

You should expect to be in the department for about an hour, although sometimes the dye takes a long time to travel through the urinary system and the examination may take longer.

Yes. You will receive a letter prior to your appointment which will tell you not to drink any fluids six hours prior to the examination. If you are diabetic and take the drug metformin, you should let the department know prior to the examination so that we can let you know when to cease and commence taking your medication.

There is a very small risk of an allergic reaction to the dye you will be given. Most people get a warm feeling as the dye is injected, and it is very rare to have a severe reaction to the dye. If you have any allergies, or have had previous allergic reactions to the dye, you should let the radiographer know.

You can return to eating and drinking as normal and the dye will pass harmlessly through your system without you noticing it. You will receive your results from your consultant in about seven days.

When it is time for your appointment, you will be asked to change into a hospital gown. Then you will have a plain x-ray of your urinary tract before your injection. When you have had your injection, you may have a tight band placed across your abdomen, which will enhance the images. After this you will have a series of x-ray’s taken which will track the progress of the dye through your urinary system. Before your final x-ray you will be asked to empty your bladder.
