Renal Dysfunction in Primary Hyperparathyroidism is associated with nephrolithiasis, elevated serum calcium-phosphate product and parathormone levels.

Renal dysfunction was associated with presence of nephrolithiasis, elevated serum CaxP and PTH levels in our cohort with predominantly symptomatic PHPT, indicating an association with the underlying disease itself. Serum CaxP may additionally be appraised during risk assessment in PHPT.
