Answer

The peak age range for calcium kidney stone production is generally 35-45 years. Another peak incidence of hypercalciuria occurs in postmenopausal women. In this older age group, many women are taking supplemental calcium for osteoporosis prophylaxis or therapy. The excess absorbed calcium eventually is released into the urine. In addition, postmenopausal women are at an increased risk of hyperparathyroidism, which can cause hypercalciuria.

Geriatric stone disease is relatively uncommon. The risk for newly formed stones in patients older than 65 years is quite low, although once a stone has formed the number and types of risk factors, as well as the risk of recurrent stones, are similar to those for younger stone formers. In particular, the incidence of hyperparathyroidism is higher in older persons and should be considered whenever an older patient presents with a first calcium kidney stone, particularly if the patient is female.

Children

Hypercalciuria can occur at any age, including in newborns. The peak incidence of idiopathic hypercalciuria in children occurs at age 4-8 years.
