Can You Have Kidney Stones Without Knowing It?

Stones that stay inside the kidney often cause no pain at all, and some are found during imaging ordered for an unrelated concern. Knowing that you have a stone gives you and your doctor a head start on monitoring it.

Can a CT Scan Miss a Kidney Stone?

CT is the most sensitive imaging test available for finding kidney stones. It detects the large majority of them, including very small ones. If a scan comes back clear, one common explanation is that the stone already passed. Your imaging team can also compare a new scan with earlier images to track any changes.

Do Kidney Stones Show Up on an Ultrasound?

Ultrasound can show larger stones and reveal swelling in the kidney caused by a blockage. It's often the preferred choice during pregnancy. When your doctor needs more clarity, including the exact size, location and number of stones, a CT scan provides the most complete detail.

Do You Need Contrast for a CT Scan for Kidney Stones?

Most kidney stone CT scans are done without contrast dye, since stones stand out clearly on their own. If your doctor also wants to evaluate the surrounding organs or blood vessels, contrast may be used to give your doctor added clarity for a more precise diagnosis.

Are CT Scans for Kidney Stones Painful?

A CT scan is painless. You'll rest on a cushioned table that glides through an open, donut-shaped scanner, so you're never fully enclosed. Your technologist positions you, explains each step and stays in contact with you the whole time. You may be asked to stay still and briefly hold your breath while the scanner captures images.
