EAST LANSING, Mich. – A Michigan State University urologist has discovered that riding a roller coaster helps patients pass kidney stones with nearly a 70 percent success rate.
David Wartinger, a professor emeritus in the Department of Osteopathic Surgical Specialties, led both a pilot study and an expanded study to assess whether the stories he was hearing from patients were true.
His pilot study is published in the Journal of the American Osteopathic Association.
“Basically, I had patients telling me that after riding a particular roller coaster at Walt Disney World, they were able to pass their kidney stone,” Wartinger said. “I even had one patient say he passed three different stones after riding multiple times.”
This resulted in Wartinger going out and testing the theory. Using a validated, synthetic 3D model of a hollow kidney complete with three kidney stones no larger than 4 millimeters inserted into the replica, he took the model in a backpack on Big Thunder Mountain at the theme park 20 times. His initial results verified patient reports.

Roller Coasters for Kidney Stones?
