Inappropriate phosphate excretion in idiopathic hypercalciuria: the key to a common cause and future treatment?

Abstract

It is proposed that patients with idiopathic hypercalciuria have an "inappropriately' high phosphate excretion for any given serum calcium concentration. Loss of phosphate may induce increased activation of 1,25-(OH)2-vitamin D. Some of the commonly described causes of stone formation may be manifestations of a single mechanism.
