Total Parathyroidectomy Alone or with Autograft for Renal Hyperparathyroidism?

Seventy-six patients underwent parathyroidectomy for renal hyperparathyroidism.There were 10 subtotal parathyroidectomies, 49 total parathyroidectomieswith implantation of part of one gland as an autograft, ninetotal parathyroidectomies with no autograft, and eight patientsin whom only three parathyroid glands were found. In 34 dialysis patients who underwent total parathyroidectomywith an autograft there was a high rate of recurrent hyperparathyroidismafter 6 years in those remaining on dialysis. Fifty per centhad asymptomatic recurrent hyperparathyodism and 30 per centrequired partial autograft excision for symptomatic hyperparathyroidism.In contrast, recurrent hyperparathyroidism was rare in renaltransplant recipients with good renal function. This favourableoutcome did not depend upon whether parathyroid surgery wasperformed before or after transplantation, or on the type ofparathyroidectomy. Total parathyroidectomy without an autograftwas performed in nine dialysis patients without any short-termadverse effects, and with clinical and pathological improvementin bone disease. In summary, the results of surgery for renal hyperparathyroidismwere excellent in patients who received a successful renal transplant.However, there was a high incidence of recurrent hyperparathyroidismin patients who remained on long-term dialysis. Total parathyroidectomywithout an autograft may be the treatment of choice in patientsunlikely to receive a renal transplant.
