How are kidney stones measured?

After being told I have a kidney stone, the doctor mentioned its size. How exactly are kidney stones measured, like what tools or methods are used to determine their dimensions? Does the size impact the treatment?

They measure them in millimeters (mm) using an ultrasound or CT scan. I had a 5mm stone last year, and the doctor told me it would pass naturally if I drank tons of water. Anything bigger than 7 or 8mm usually needs some medical procedure to break it down.

They are measured in tiny millimeters by doctors using ultrasound scans! Usually, if the stone is under 5mm, it is considered small and can wash out with lots of water. Just stay positive and keep that water bottle handy!

They are measured in millimeters using imaging tests like ultrasound or CT scans. Please don't worry too much, as your doctor will look at the size and tell you the best way to handle it. Wishing you a very speedy recovery.

When I saw '6mm stone' on my report, I panicked completely thinking I would need major surgery. But my doctor smiled and said it's actually quite small and very manageable with some oral fluids and syrup. The measurement in mm helps them decide if you need active treatment or just water.

Haan na, they always write the size in mm on the sonography report. My husband had a 6mm stone and we got so scared looking at the report. But the doctor explained that most small stones pass on their own with proper medication and water.

I just got cleared of my kidney stone last month! They measured it at 8mm via a non-contrast CT scan, which is the most accurate way. The ultrasound can sometimes slightly overestimate or underestimate the size, so trust the CT report more.

You will need to get an ultrasound or a CT KUB scan done, which takes barely 15 minutes, and the radiologist will measure the stone size in mm. If the report says it is less than 5mm, it usually passes with hydration. Don't waste time guessing, just book the scan and show the report to a urologist.

In our younger days, we just relied on the doctor's physical checkup, but now these modern ultrasound machines measure everything down to the exact millimeter. I had a 4mm stone years ago that passed quite easily without any major treatment. Have faith in your doctor's advice, things are much easier now.
