[Surgical treatment of renal hyperparathyroidism. Experience in 71 patients]

Surgery is an effective method for the management of renal hyperparathyroidism.

To report the clinical presentation and results of surgical treatment of renal hyperparathyroidism.

Retrospective analysis of 58 patients aged 46 ± 11 years with secondary hyperparathyroidism (HPT2) and 13 patients aged 53 ± 11 years with tertiary hyperparathyroidism (HPT3), operated at a clinical hospital.

In 55 cases (77.4%) the indications for surgery were complications of excess parathyroid hormone (PTH) and in 16 patients (22.6%) a failure of medical treatment. Total parathyroidectomy with intraoperative measurement of PTH (PTHop) plus a forearm parathyroid autograft was performed in 54 (93.1%) patients with HPT2 and in all patients with HPT3. PTHop decreased ≥ 75% in 51 patients (88%) with HPT2 and in 9 patients (69.2%) with HPT3, respectively. Cure of the disease was achieved in 52 (89.7%) and 11 (84.6%) patients with HPT2 and 3, respectively. Median follow-up was 41 months. Five (9.6%) patients with HPT2 and two patients (18.2%) with HPT3 had a recurrence of the disease.

In patients with renal hyperparathyroidism, the primary indication for surgery was the presence of complications of PTH excess. A drop in PTHop ≥ 75% from baseline predicts healing in 98% and 100% of cases with secondary or tertiary HPT respectively. Surgery was a safe and effective treatment in both groups.
