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.
Pregnant women tend to have a higher calcium intake, but their kidneys do not handle the calcium as well as they did prior to pregnancy. Kidney stones are still rare during pregnancy, however, affecting only 1 in 1,500 pregnancies.tones in the urinary tract in children are usually due to genetic factors. Most of the time, the cause is too much calcium in the urine (hypercalciuria). Deformities in the urinary tract pose a significant risk for kidney stones in children.
