| Abstract: | Parathyroidectomy was studied retrospectively in 107 patients with primary hyperparathyroidism. This condition was diagnosed by measuring both the total serum calcium and ultrafilterable calcium (non-protein-bound) levels. The identification of ultrafilterable calcium is an important adjunct to parathyroid surgery as it allows the diagnosis of hyperparathyroidism when the total serum calcium level is normal. The surgical technique for selective parathyroidectomy and multiple biopsies was uniform. Parathyroid adenoma was discovered in 73 patients, diffuse hyperplasia in 26 and combined disease in 8. Postoperatively, two patients suffered from permanent hypocalcemia and three had hypercalcemia. |
