What is this test?

This is a radiographic urinary tract study, not a blood test. Contrast material is introduced through an existing urinary catheter so that detailed images of the bladder and nearby urinary tract structures can be taken.

Why might I need this test?

It may be ordered to evaluate urinary tract anatomy, suspected blockage, leakage, abnormal connections, or problems involving the bladder. The images may also help clinicians assess how contrast passes through the urinary tract.

How is the test performed?

An imaging technologist takes images before and after contrast is given through the existing catheter. The bladder may be filled to make its outline and nearby structures easier to see. You will usually be asked to remain still and may be instructed to change positions.

How do I prepare for the test?

Follow the radiology department's instructions about the existing catheter and bladder filling. Tell the care team if you have had a prior contrast reaction, have kidney problems, or may be pregnant, and do not remove or empty the catheter unless specifically instructed.

Frequently asked questions

Is this the same as a routine blood test?
No. This is an imaging procedure that evaluates the urinary tract using contrast and an existing urinary catheter.
Do I need a new catheter for this test?
The test title indicates that an existing catheter is used. Confirm with the imaging department whether the catheter should be positioned or filled in a particular way beforehand.
Will I need to be awake during the test?
Usually, yes. The procedure is generally performed without anesthesia, although sedation may occasionally be used when necessary.
