Imagine enduring the excruciating pain of a kidney stone—only to have it disappear after a roller coaster ride. Sounds ridiculous, right? Well, that’s exactly what happened to one man.

When he told his doctor, they thought it was a joke.

But then, something strange happened… More and more patients reported the same thing.

The Science Behind the Ride

Doctors couldn’t ignore it anymore. They decided to put this bizarre theory to the test.

Researchers built a 3D-printed kidney, filled it with real kidney stones, and took it on Disney World’s Big Thunder Mountain Railroad—not once, not twice, but 20 times!

And the results?

Why the Back Seat Works Best

Where you sit actually matters.

• Sitting in the BACK? The stones passed 64% of the time!
• Sitting in the FRONT? The stones passed only 17% of the time.

Turns out, the intense vibrations and rapid movement in the back seat help shake the stones loose, making them pass through the urinary tract much faster.

Could This Be a New Medical Treatment?

Doctors believe that roller coasters could help patients after treatments like lithotripsy (which breaks kidney stones into smaller pieces). By riding a coaster, patients might be able to flush out smaller stones before they grow larger and cause more problems.

So… should hospitals start building roller coasters?

Maybe not just yet. But if you ever find yourself dealing with a small kidney stone, a trip to Disney World might just be the most fun prescription ever!
