We retrospectively studied clinical problems for 55 patients with primary hyperparathyroidism who were operated on at our hospital.The chance to discovery of primary hyperparathyoidism and its accompanied symptoms were various. Other than classical symptoms, hypertension was noted in 12 patients and malignant tumors in 9. Forty-four percent of patients who had no bone related symptoms were found to have decreased bone mineral density (BMD). Even the patients with normal BMD were seen to increase the BMD, postoperatively. We thought that the parathyroidectomy was indicated for the asymptomatic patients with normal BMD. Biochemical investigation showed that positive rate were 50% for PTH-C, 94% for PTH-HS, 78% for intact PTH, 87% for serum total calcium and 98% for serum ionized calcium. Serum ionized calcium and intact PTH were useful for the diagnosis of patients who had normocalcemia or slight elevation of serum calcium.The sensitivity was 61% for ultrasound sonography (US) and 49% for computer tomography (CT) and scintigram, respectively. The detection rate of US and CT was positively related to the size of the parathyroid glands, but scintigram was not.The rate with which the parathyroid glands can be recognized during operation increased from 30% in the former group to 52% in the later group. As a result, 11% of the patients with adenoma had too much surgery and 29% of the patients with hyperplasia had too little surgery.
