    Abstract:
    A retrospective analysis was undertaken to better define the clinical presentation and therapy of patients with secondary hyperparathyroidism and the timing of surgical removal of the parathyroid glands in secondary hyperparathyroidism. Sixty-eight patients with end-stage renal disease (ESRD) underwent 74 parathyroid procedures over a 10-year period. There were 38 per cent women and 62 per cent men in this population--the same proportion of men and women with ESRD. These proportions are reversed when compared with patients with primary hyperparathyroidism. The mean time between initiation of dialytic therapy and parathyroidectomy was 5.4 years. Preoperative mean serum calcium and phosphorus levels were 10.1 +/- 0.2 and 6.1 +/- 0.2 mg/dl, respectively. All patients were symptomatic and 60 per cent of the patients had at least two symptoms before surgery. Renal osteodystrophy was the most common symptom (74%), whereas pruritus was noted in 65 per cent of this population. Patients underwent either subtotal (88%) or total (12%) parathyroidectomy with autotransplantation. Six patients required reoperation: five for recurrent disease (2 to 5 years after the initial surgery) and one for persistent disease. All patients were symptomatically improved after the surgery. Complications included the following: transient hoarseness (7%), hypocalcemia requiring calcium, and/or vitamin D therapy (32%) for 6 months after surgery. This analysis demonstrates that although the initial therapy of secondary hyperparathyroidism is medical, surgical therapy should be instituted before multiple symptoms develop in the ESRD population.
