[Behavior of prolactin secretion and 25-hydroxycholecalciferol level in patients with active kidney calculi]

In 76 patients with urolithiasis the behaviour of the level of 25-OH-D and prolactin, respectively, and the metabolism of calcium and phosphate were investigated after an intravenous calcium load. In these patients a significant lower 25-OH-D level and a significant lower increase of the serum phosphate level after calcium load was observed in comparison with healthy adults. However, in contrast to healthy probands, the prolactin level was suppressed significantly. A participation of these endocrine changes in the pathogenesis of pathogenesis of urolithiasis could be suggested.
