For reasons unknown, kidney stones are growing increasingly common than they were at the start of the 20th century.

A kidney stone is a hard mass developed form crystals that separate from the urine and build up on the inner surfaces of the kidney. Normally urine contains chemicals that prevent the crystals from forming. These inhibitors do not seem to work for everyone.
