Medical and surgical aspects of parathyroidectomy

A more logical approach to the management of the chronic dialysis patient with parathyroid hyperplasia has become possible thanks to recent progress in cellular and molecular analysis of surgically removed parathyroid glands and accumulation of clinical experience. When one or more parathyroid glands progress to the stage of nodular hyperplasia, it is usually difficult to control PTH secretion even by calcitriol pulse therapy. For such patients, we have developed two new therapeutic approaches, i.e., selective percutaneous ethanol injection therapy (PEIT) and direct calcitriol injection therapy, in combination with medical therapy. For optimal selection of therapeutic modalities it is indispensable to evaluate the degree and stage of parathyroid hyperplasia. For successful management, prevention of nodular hyperplasia is the most important strategy.
