A VCUG (voiding cystourethrogram) is a test that takes pictures (x-rays) of your bladder to find out if your urine is flowing backward into your ureters and kidneys. The bladder is where your urine is stored until you go to the washroom.
You may have a lot of questions about this test.
You can eat and drink like you normally do before this test. If you’re taking antibiotics for a bladder or kidney infection, you must have been taking this medicine for at least 48 hours before we can do this test.
The room will have a really big camera over a bed. This room is often a little cool. The machines work better when the air is cooler.
The big camera is hooked up to a TV screen. The screen lets the doctor doing your test watch the inside of you.
You’ll also see a bottle full of liquid (called a contrast) hanging on a pole. A plastic tube will be connected to the bottle. This thin plastic tube is what the doctor uses to get the contrast material from the bottle into your bladder.
The contrast outlines the inside of your bladder so the doctor can “see” the inside of your bladder better.
You can go home after the test. You may feel a little sore the next few times you go to the washroom—but this will go away in a few days.
You can carry on with your day as usual.
Your family doctor will get the results of the scan in about 1 week. Please call your doctor’s office for the results.
