[Personal experiences in the diagnosis and treatment of primary hyperparathyroidism].

It is reported on an interdisciplinary team consisting of internists, radiologists and urologists which treated twelve patients with suspicion of primary hyperparathyroidism. The diagnostics is performed in form of a three-step progamme. A great importance is still ascribed to hypercalcaemia and therefore it serves as leading symptom. By means of the selective determination of parathormones no clear side classification could be achieved. In ten patients the operation could successfully be finished with the exstirpation of one or more adenomas of the parathyroid glands. A special importance deserves the intensive postoperative control with regular determinations of serum calcium in order to encounter in time a hypocalcaemia with tetanies by applications of calcium. It is referred to the necessity to search for an adenoma of the parathyroid gland at the slightest suspicion of the presence of a primary hyperparathyroidism.
