Answer

More than 30 million Americans experience kidney stone disease, with 1.2 million new cases each year. The percentage of people with hypercalciuria has been estimated to be at least 1 in 3 among people who form kidney stones, although some investigators have suggested that hypercalciuria can be found in as many as 60% of all calcium-stone formers. It is the most common metabolic abnormality found with calcium nephrolithiasis.

Despite a higher incidence of stone disease in the "stone belt," which is primarily the southeast portion of the United States, no clear biochemical difference was found when risk factors were compared among various regions of the country. Although nutritional and environmental influences would be expected to produce some variability, stone formers in all of the regions tested showed a striking similarity in urinary chemical risk factor profiles, with no significant biochemical differences noted that could be attributable to geographic factors.
