[New interventions controlling parathyroid hormone].

Percutaneous direct injection of ethanol, calcitriol and the analogues to parathyroid glands under ultrasonography have been performed as a therapeutic option for advanced secondary hyperparathyroidism in uremic patients. The aim of these therapy is mass reduction of enlarged parathyroid glands and injection of maxacalcitriol may induce apoptosis of parathyroid cells. The indications and limitations of these therapy have been confirmed. However the most successful treatment for renal hyperparathyroidism is parathyroidectomy.
