Answer

Nephrolithiasis occurs in all parts of the world. The incidence of urinary tract stone disease in developed countries is similar to that in the United States; the annual incidence of urinary tract stones in the industrialized world is estimated to be 0.2%. Stone disease is rare in only a few areas, such as Greenland and the coastal areas of Japan. A lifetime risk of 2-5% has been noted for Asia, 8-15% for the West, and 20% for Saudi Arabia.

In developing countries, bladder calculi are more common than upper urinary tract calculi; the opposite is true in developed countries. These differences are believed to be diet-related.
