Determinants of hypercalciuria and renal calcifications in chronic hypoparathyroidism: A cross-sectional study.

Hypercalciuria, impaired renal function and renal calcifications are common in hypoparathyroidism. Hypercalciuria is to a large extent explained by indices of known physiological importance to 24 h U-Ca. However, in the present study, a high renal calcium excretion did not explain renal impairment or kidney calcifications.
