[Surgical treatment of refractory hyperparathyroidism and usefulness of the intraoperative PTH].

Objective: To share our experience in the surgery of so-called refractory hyperparathyroidism (secondary and tertiary without response to therapy with calcitriol).

Material And Methods: Retrospective study based on 41 patients-5 with secondary and 6 with tertiary hyperparathyroidism-referred by nephrology for surgical evaluation of their illness because of poor response to the medical treatment given.

Results: In 18 of the 41 cases we used the fast or turbo intra-operative PTH with reduction of more than 60 % in all patients.
