[Arterial pressure in idiopathic calcium nephrolithiasis].
Hypertension and calcium nephrolithiasis show some common features, such as the high prevalence of hypercalciuria and of elevated urinary sodium excretion. 28 patients with idiopathic calcium stone disease and 17 normals were studied: all the subjects were evaluated for the mean arterial pressure, and for the metabolic risk factors for calcium stone disease. The mean arterial pressure proved to be higher in patients with calcium nephrolithiasis than in normals. In normals the mean arterial pressure showed a direct relationship with the urinary calcium, while in the group of stone patients it had a direct relationship with the urinary sodium excretion. The lack of relationship between the mean arterial pressure and calcium excretion, in patients with calcium stones, suggests an impaired tubular calcium handling in such patients.
