CT KUB: What to Expect from a CT Scan of Kidneys, Ureters, and Bladder

What is a CT KUB?

A CT KUB is a special type of CT scan. It takes detailed pictures of your kidneys, ureters, and bladder. Doctors use this test to look at your urinary tract. Often, a CT KUB helps find the cause of pain, blood in urine, or other urinary problems. This scan is also called a CT scan of kidneys or urinary tract imaging. It uses X-rays and a computer to create clear images inside your body.

Why is a CT KUB Performed?

Doctors may suggest a CT KUB for several reasons. For example, it helps find kidney stones, infections, or blockages. Sometimes, it checks for injuries or tumors in the urinary tract. If you have symptoms like pain while urinating, blood in urine, or lower back pain, your doctor may order this scan. In addition, a CT KUB can help plan treatments or surgeries.

How to Prepare for a CT KUB

Preparing for a CT KUB is simple. However, you should always follow your doctor’s instructions. Here are common steps to get ready:

Do not eat or drink for a few hours before the scan, if told by your doctor.

Tell your doctor about any allergies, especially to iodine or contrast dye.

Inform your doctor if you are pregnant or think you might be.

Wear comfortable, loose clothing to your appointment.

Remove jewelry, belts, or metal objects before the scan.

Sometimes, you may need to drink water or a special liquid before the scan. Your doctor will let you know if this is needed.

What to Expect During the Procedure

During a CT KUB, you will lie on a table that slides into the CT scanner. The scan itself is painless and usually takes less than 15 minutes. You may need to hold your breath for a few seconds while the machine takes pictures. If a contrast dye is used, it may be given by mouth or through a vein. The dye helps make the images clearer. After the scan, you can return to your normal activities right away.

Risks and Safety of CT KUB

CT KUB scans are generally safe. However, like all X-ray tests, they use a small amount of radiation. For most people, the benefits outweigh the risks. Here are some things to keep in mind:

Radiation exposure is low, but not recommended for pregnant women unless necessary.

Some people may have an allergic reaction to the contrast dye.

Drinking plenty of water after the scan helps flush out the dye.

If you have kidney problems, tell your doctor before the scan.

According to the World Health Organization (WHO), CT scans are safe when used properly. Always discuss any concerns with your healthcare provider.

Understanding Your CT KUB Results

After your CT KUB, a radiologist will review the images. They look for signs of kidney stones, infections, tumors, or other problems. Your doctor will explain the results and what they mean for your health. Sometimes, more tests may be needed. If the scan finds a problem, your doctor will discuss treatment options with you.
