How is CT KUB Performed? (Procedure Overview)
First, you will lie down on a special table. Then, the table slides into the CT scanner, which looks like a large ring. The machine takes many X-ray pictures from different angles. After that, a computer combines these images to create clear pictures of your kidneys, ureters, and bladder. The scan usually takes about 10 to 20 minutes. Most of the time, you do not need an injection or dye for a CT KUB scan. However, in some cases, your doctor may use a contrast dye to get better images.

After the scan, you can usually return to your normal activities right away. If you received contrast dye, drink plenty of water to help flush it from your body. Your doctor will tell you if you need to take any special steps after the scan.
