Bone Mineral Content and Recurrent Calcium Nephrolithiasis with Idiopathic Hypercalciuria
Hypercalciuria has been associated with a decrease in bone mineral content (BMC) but this finding is still debated (1). In the present study, we followed 12 male patients age 44.4±13.2(±SD) years with recurrent Ca nephrolithiasis (RCN) and idiopathic hypercalciuria (IH) for a one-year period, comparing their data with those of 12 matched normal subjects. In the patients, mean urinary Ca excretion was 372±128 mg/day and their average stone occurrence was 10.2±1.2 calculi/patient. All individuals had previously undergone conservative treatment for their stone disease using low Ca and oxalate diets and had not received any specific pharmacological therapy.
