title: Parathyroidectomy in chronic renal failure.
abstract: Between 1978 and 1984, 19 patients at Royal Perth Hospital (RPH) underwent parathyroidectomy for secondary (renal) hyperparathyroidism. This represented 6.0% of the overall dialysis population treated at RPH during this period of time. The mean duration of pre-operative dialysis for these 19 patients was 48 months, compared with a mean duration of 30 months for the overall dialysis population. The principal indications for parathyroidectomy were symptomatic hyperparathyroid bone disease (10), hypercalcaemia (six), progressive lower limb ischaemia (two) and painful peri-articular calcification (one). The complications of chronic renal failure that were most consistently improved by parathyroidectomy were the clinical, radiological and biochemical manifestations of hyperparathyroid bone disease and hypercalcaemia. Features such as pruritus, soft tissue calcification, vessel wall calcification and peripheral ischaemia responded less predictably. Hyperparathyroid bone disease and hypercalcaemia remain the principal indications for parathyroidectomy in chronic renal failure. Profound postoperative hypocalcaemia was the major early postoperative management problem (seven patients) and was closely linked with the severity of pre-operative hyperparathyroid bone disease. It was also seen more frequently in those patients undergoing total parathyroidectomy with immediate autotransplantation of parathyroid tissue (TP-A), than in those in whom residual parathyroid tissue was left in situ (subtotal parathyroidectomy or STP). Recurrent hyperparathyroidism (four patients) was the major late postoperative complication, but was more frequently the result of a supernumerary or previously overlooked fourth parathyroid gland (three), than due to hyperplasia of residual parathyroid tissue (one). STP and TP-A were equally effective in controlling or reversing renal hyperparathyroidism, but the former was associated with a lower incidence of postoperative management problems and should be the preferred operation in this group of patients.
