Patients with both skeletal and renal manifestations had higher serum calcium levels than those with isolated skeletal involvement [12.5 (11.1\u201313.7) mg\/dL, 11.2 (10.6\u201312.3) mg\/dL, respectively; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05]. Serum alkaline phosphatase (AP), plasma parathyroid hormone (PTH) levels, and parathyroid tumour weight were significantly higher in patients with isolated skeletal, and both skeletal and renal manifestations, compared to the other two groups. A preoperative PTH and AP level of 300\u2009pg\/mL\u00a0and 152\u2009U\/L, predicted the risk of developing skeletal involvement with sensitivity and specificity of 71%, 70%, and 69%, 67%,
