Hypercalciuria in sarcoidosis.

In 18 cases of sarcoidosis, 11 presented with hypercalciuria. Absorptive hypercalciuria was usually involved, but 2 patients had probably a calcium renal leak. Therapy with sodium cellulose phosphate was usually effective in lowering the amount of urine calcium, but thiazides had to be used concomitantly in three cases.
