The mean patient age was 57.1 \u00b1 12.1 years and 82.4% were women. Before parathyroidectomy, mean calcium and parathyroid hormone (PTH) levels were 11.2 \u00b1 1.0 mg\/dL and 331 \u00b1 584 pg\/dL, respectively. Hypercalcaemia was present in 84.3% of patients. All eight patients with normal calcium levels had elevated PTH levels. Only two patients did not have PTH above the normal range, although both had elevated calcium levels. The most common urinary disorders were low urinary volume (64.7%), hypercalciuria (60.8%), high urinary pH (41.2%) and hypocitraturia (31.4%).

Low volume, hypercalciuria, high urinary pH, and hypocitraturia are the most frequent urinary disorders. Parathyroidectomy is effective in normalizing serum calcium and PTH levels, although other urinary metabolic may persist.
