Abstract:
A prospective study was disigned to determine the frecuency of idiopathic hypercalciuria in children. Urinary calcium excretion was examined in 305 healthy and white patients between 3 and 14 years old of age. We determined calcium/creatinine excretion ratio and calcium fractional excretion in collected urine samples during afternoon-night and they were greater than 0,21 and 0,13 respectively in 63 (`x: =0.30 ± 0.07) and 53 (`x: 0,19 ± 0,05). In theses cases we determined the same paramenters after an overnight fast and they were greater than 0.21 and 0,13 respectively in 32 (`x: 0,30 ± 0.07) and 30 (`x: 0.18 ± 0.04). The hypercalciuria has been defined as urinary calcium excretion exceeded 4 mg/kg/day and was identified in 26 patients (8.52%), 14 males (53.84%) and with family history of urolithiasis in 53.84%. All patients with hypercalciuria had during 3 months a diet regular in calcium (500 mg/day), avoiding high dietary sodium intake and encoraging water intake, resulting normal values for calciuria in 19 (73%).Keywords: Idiopathic hypercalciuria. Urolithiasis. Hematuria.
