Abstract

Hypercalciuria has long been recognized as an important metabolic derangement associated with the formation of calcareous renal stones. Hypercalciuria increases the saturation of the urine with respect to stone-forming salts and reduces inhibitor activity. There is now ample evidence that 'idiopathic hypercalciuria' is a heterogeneous disorder, comprising several entities including absorptive, renal and resorptive forms of hypercalciuria. Absorptive hypercalciuria is the most common variety, and recent studies suggest that in a large subset of these patients, increased intestinal calcium absorption is caused by increased production of calcitriol or greater sensitivity to calcitriol (e.g. upregulation of vitamin D receptors). Reduced spinal bone density found in these patients may relate to increased action of calcitriol on boneor to other factors. Since patients with vitamin D-dependent absorptive hypercalciuria may develop negative calcium balance when placed on diets restricted in calcium, therapy is shifting from severe dietary calcium restriction and sodium cellulose phosphate (calcium-binding resin) to thiazides and orthophosphates, which promote calcium retention. For each form of hypercalciuria, selective therapy should provide thebest results.
