[A clinical study of primary hyperparathyroidism].
Eight cases of primary hyperparathyroidism (P-HPT) confirmed pathohistologically, between April, 1974 and January, 1986 at our department, were reviewed. The patients consisted of three males and five females, ranging in age from 38 to 62 years old with an average of 50.3 years. All the cases belonged to the urolithiasis type and seven patients were recurrent or/and multiple stone-formers. Positive rates of the laboratory values studied in relation with P-HPT were 100% in serum Ca, C terminal parathyroid hormone, and % TRP, 87.5% in urine Ca, 75% in serum Cl/P ratio, alkaliphosphatase, 50% in serum Cl, 37.5% in serum P and 0% in urine P. Seven cases had clinically apparent hypercalcemia, while one was a so-called borderline P-HPT with intermittent hypercalcemia. The correct diagnosis of the localization was obtained preoperatively in two cases by angiography and one by C.T and Tl-Tc subtraction scintigraphy. Histological findings of the tumors extirpated by the cervical operation were parathyroid adenomas in six cases and hyperplasia in two. During the course of the postoperative follow up, hypercalcemia and urolithiasis did not recur in any case including two of hyperplasia.
