Eighty-four patients have undergone surgical exploration following a clinical diagnosis of hyperpathyroidism over a 20-year period. Urinary tract calculi were the major indication for exploration, and 90% of these patients had recurrent calculi. Osteitis fibrosa was a rare presentation of hyperparathyroidism. Lethargy, sometimes profound, was an important symptom, in some instances the dominant feature. Persistent hypercalcaemia remains the chief diagnostic investigation, with helpful confirmation from estimation of the parathyroid hormone level. Little attempt was made in this series to utilize preoperative localization techniques, reliance being placed on meticulous bloodless surgery to find normal and abnormal parathyroid tissue. Eighty-five explorations were carried out in the 84 patients. Seventy-four of the explorations were successful, converting the patient to a normocalcaemic state. Of these, 63 had a single adenoma (86%).
