Renal deposition of calcium-phosphate or calcium-oxalate results in nephrocalcinosis. This disorder is more frequently found in children and preterm newborns and deposits are more frequently composed by apatite and begins within medulla. In rare patients with primary hyperoxaluria (type 1 or 2) deposits are cortical and composed by calcium-oxalate. Nephrocalcinosis may occur in the course [...]
Kidney stone disease may be considered as the main complication of hypercalciuria. Despite the amount of research, the first evidence that hypercalciuric subjects are predisposed to kidney stones was recently provided in a work, displaying that the risk to produce stones increased with calcium excretion in general population. Previous studies had limited their observation to [...]
In most of patients, primary hypercalciuria results from an increase of intestinal calcium absorption (absorptive hypercalciuria). In less than 5% of patients, primary hypercalciuria may be caused by a primary defect in tubular calcium reab- sorption (renal hypercalciuria). These different forms of hypercalciuria are clinically distinguished with the measurements of fasting calcium excretion and plasma [...]
Introduction Primary hypercalciuria is a defect of calcium metabolism, characterized by increased 24 hour urinary calcium excretion which is not justified by any apparent metabolic alteration. Its prevalence is 5-10% in the general population, but is significantly higher in patients with calcium kidney stones, nephrocalcinosis, arterial hypertension and osteoporosis.
