The purpose of this study is to assess if estrogen replacement normalizes urinary calcium excretion in postmenopausal women with hypercalciuria and low bone mass and to assess for differences in response to estrogen replacement in women with familial hypercalciuria compared to nonfamilial hypercalciuria.
