title: Surgical findings and results of subtotal and total parathyroidectomy in hypercalcemic patients with uremic hyperparathyroidism.
abstract: Surgical and histopathologic findings and results of subtotal resection and total parathyroidectomy with autotransplantation were evaluated in 82 hypercalcemic patients with uremic hyperparathyroidism. The mean preoperative serum calcium concentration was 2.89 mM, and the highest values were associated with more rapidly progressing hypercalcemia. Despite greatly increased total weight of the parathyroid tissue (mean 1,509 mg), 34 patients had one to five normal-sized parathyroid glands. The incidence of such glands decreased with total gland weight. Nodular hyperplasia was found in 74% of the patients, and was characterized by considerable intraindividual size difference, while diffuse hyperplasia was associated with more moderate and symmetric glandular enlargement. During follow-up averaging 4.5 years, the incidence of persistent or recurrent hypercalcemia was slightly higher after subtotal than after total parathyroidectomy (11 and 11%, vs. 9 and 7%). Biochemical and/or radiologic signs of parathyroid bone disease were present in 36 (44%) of the patients before neck exploration and normalized postoperatively in all but seven. The outcome of parathyroid surgery thus was favorable in uremic patients with hypercalcemic hyperparathyroidism.
