title: [Protective use of calcium in case of osteoporosis versus calcium oxalate stones].
abstract: In patients with calcium-containing kidney stones calcium supplements are officially contraindicated. Recent studies showed a protective effect by calcium-supplementation when taken with meals, analogous to the decreased risk of kidney stones by dietary calcium due to binding of oxalate. However, because of the poor compliance, costs and the official contraindication for calcium supplements in patients with kidney stones, dietary calcium intake should be preferred whenever feasible.
