Combined Primary Hyperparathyroidism and Absorptive Hypercalciuria: Clinical Implications
Primary hyperparathyroidism accounts for five % of kidney stones. This is our experience as well as that of others. Absorptive hypercalciuria, characterized by excessive intestinal absorption of calcium, is present in 45% of stone formers. It should not be surprising that these two common causes of nephrolithiasis may occasionally occur together. In this report, we describe five patients who presented with combined primary hyperparathyroidism and absorptive hypercalciuria. It will be shown that when these disorders occur together, there are important implications both before and after parathyroidectomy.
