Hypercalciuria can be classified as idiopathic or secondary. Idiopathic hypercalciuria can be diagnosed when clinical, laboratory, and radiographic investigations fail to delineate an underlying cause. Secondary hypercalciuria occurs when a known process produces excessive urinary calcium. (See Pathophysiology, Etiology, and Workup.)
