Getting rid of kidney stones may
now be as fun as riding on a roller coaster, according to scientists who found
that the activity helps patients pass stones with 70% success rate. Using a
validated, synthetic 3D model of a hollow kidney with three kidney stones no
larger than 4 millimeters, he took the model in a backpack and rode a roller
coaster 20 times. Sitting in the last car of the roller coaster showed a 64%
passage rate, while sitting in the first few cars only had 16% success. Then the
researchers rode the same roller coaster with multiple kidney models attached
to the researchers.
They also found that both studies
showed a 100% passage rate if the stones were located in the upper chamber of
the kidney. Researcher said roller coasters too fast or too violent won’t work
as the G-force pins the stones into the kidney and doesn’t allow it to pass. The
ideal coaster is rough and quick with some twists and turns, but no upside down
or inverted movements. Lithotripsy, which breaks apart kidney stones that are
too large to pass, is a common treatment but it can leave remnants in the kidney
which can result in another kidney stone.
