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.
Kidney stones are often caused by problems in the kidney's ability to handle calcium. In addition, the kidney's role in maintaining blood calcium is important in the bone disease osteoporosis that afflicts many elderly people, especially women.
