title: [Prevalence of hypercalciuria in postmenopausal women with osteoporosis].
abstract: OBJECTIVE
  To determine the prevalence of hypercalciuria (HC) in postmenopausal women with osteoporosis and its relationship with clinical data and bone mineral metabolism.
  
  
  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 (±SD) was 64 (±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 ± 6 vs. 50 ± 3 years HC, p < 0.0005). No association was found between calciuria and age, BMI, BMD, calcium, phosphorus, PTH, and alkaline phosphatase.
  
  
  CONCLUSIONS
  HC is frequent in postmenopausal women with osteoporosis, and calciuria measurement should be included in the investigation of these patients.
