| Abstract: | In the group of 1635 patients with nephorolithiasis the authors found 16% with idiopathic hypercalciuria. They administered thiazide diuretics for 8 days as a test for the detection of masked hyperparathyroidism in idiopathic hypercalciuria. In 6 cases which were diagnosed in this manner, the existence of a parathyroidadenoma could be demonstrated by surgical operation. The hypercalciuria persisted after exstirpation of the tumor, in some cases the nephrolithiasis also remained active. the various pathogenetic mechanisms connected with these common diseases are discussed in relation to these results. |
