title: Long-term follow-up after total parathyroidectomy without parathyroid reimplantation in chronic renal failure.
abstract: Forty-three patients with secondary or autonomous hyperparathyroidism complicating chronic renal failure (CRF) underwent total parathyroidectomy (PTX) (follow-up 2-18 years, mean 8.7 years). Five were on conservative treatment for CRF, 35 on regular dialysis, and only three had a functioning allograft. At PTX, the most frequent findings were uncontrollable hypercalcaemia, musculo-skeletal pain, radiographic changes in the phalanges, and raised plasma parathyroid hormone (PTH) concentration. Pre-operatively, all patients were loaded with dihydrotachysterol or 1-alpha-OH cholecalciferol. Postoperatively, they were maintained on tapering doses of the same drugs and, briefly, oral calcium supplements. Five glands were identified and removed in two patients, four in 35 patients, three in three patients and only two in one patient. All had changes of hyperplasia and adenoma formation, except for one with a parathyroid carcinoma. Prompt symptomatic and radiographic improvement occurred, with normalization of plasma calcium and alkaline phosphatase. Postoperative PTH levels were available in 33 patients (23 by intact PTH assay): they were persistently high in 10/33 (2/23 intact); normal in seven (6 intact); low in 11 (3 intact), and undetectable in four (3 intact). Thus, PTX was incomplete in the majority of patients. Following transplantation, 3/20 (3/18 intact) patients still had detectable PTH. Only one patient developed symptomatic recurrent parathyroid disease requiring re-operation, and complications were few. Small dosages of vitamin D continue to be required, but not calcium supplementation, and no clinical effects of possible adynamic bone have been noted. At later renal transplantation in 27 patients, an easily treatable, uncomplicated hypocalcaemia was noted in 33%.(ABSTRACT TRUNCATED AT 250 WORDS)
