Prevalência de hipercalciúria em mulheres na pós-menopausa com osteoporose

objective: to determine the prevalence of hypercalciuria (hc) in postmenopausal women with osteoporosis and its relationship with clinical data and bone mineral metabolism. subjects and methods: calciuria was measured in 24-hour urine samples of 127 women. bmd was measured in the lumbar spine and femur by dual-energy x-ray absorptiometry (dxa). results: mean age (a±sd) was 64 (a±8) years. according to urinary calcium excretion, patients were divided into normo- and hypercalciuric (hc). of the 127 patients, 19 (15%) were classified as hc. the only difference between the groups was the age of onset of menopause (46 a± 6 vs. 50 a± 3 years hc, p < 0.0005). no association was found between calciuria and age, bmi, bmd, calcium, phosphorus, pth, and alkaline phosphatase. conclusion: hc is frequent in postmenopausal women with osteoporosis, and calciuria measurement should be included in the investigation of these patients.
