A 44-year-old woman was examined whose first symptom of hyperparathyroidism was nephrolithiasis. This was resolved by ureteromeatotomy and passage of the calculus. The calculus was composed of calcium phosphate and oxalate. Routine biochemical studies showed serum calcium levels varying between 12.4 and 13 mg/100 ml (normal, 9 to 11 mg/100 ml); serum inorganic phosphorus, 1.7 to 2.1 mg/100 ml (normal, 2.5 to 4.5 mg/100 ml); and elevation of alkaline phosphatase to 4.85 Bessey Lowry U (normal, 0.8 to 2.3 Bessey Lowry U). Urinary clearance of phosphorus and urinary calcium were normal. Serum radioimmunoassayable parathyroid hormone was 300 and 403 pg/ml
