Kidney stones are one of the most painful disorders, and one of the most common disorders of the urinary tract. The National Institute of Diabetes and Kidney Disease (NIDKD) estimates that about a million people in the United States are treated for kidney stones each year. Consider these NIDKD statistics:
- Caucasians are more prone to kidney stones than are African-Americans.
- Although stones occur more frequently in men, the number of women who develop kidney stones has been increasing.
- Kidney stones strike mostly people between age 20 and 40.
- Once a person develops more than one stone, he/she is more likely to develop additional stones.
