Prevalence of Kidney Stones The lifetime incidence of kidney stones is nearly 13 percent in men and 7 percent in women. Once an individual has formed a stone, the likelihood of recurrence is 50 percent or greater at five years and up to 80 percent at 10 years.
Calcium stones (80 percent of stones) Calcium stones are the most common type of kidney stone. There are two types of calcium stones: calcium oxalate and calcium phosphate. Calcium oxalate is by far the most common type of calcium stone. Some people have too much calcium in their urine, raising their risk of calcium stones.
