title: [Magnesium excretion in recurrent calcium urolithiasis].
abstract: Patients with recurrent non-infectious calcium urolithiasis were classified metabolically (122 patients). When the magnesium excretion was measured in the metabolic subgroups, a subset of patients (21.6%) could be identified with marked hypomagnesuria as the only metabolic abnormality. A significantly reduced rate of magnesium excretion was found in these normocalciuric stone formers while assessing the overall 24-h urine magnesium excretion or the 24-h urine and fasting urine magnesium to calcium ratio. These differences were apparently not due to factors that might modify renal magnesium excretion, such as parathyroid function, hypercalcemia, hypophosphatemia, alimentary sodium load, age and sex.
