Hereditary Hypercalciuric Urolithiasis: A Study of a Family

Summary— A family affected with hereditary hypercalciuric urolithiasis is presented. The data suggest that the primary defect is idiopathic hyperabsorptive hypercalciuria, transmitted by an autosomal dominant pattern. This syndrome seems to be common among patients with hypercalciuric urolithiasis. Investigation of the family of such patients and preventive treatment at the earliest age possible are suggested.
