Reoperation for secondary hyperparathyroidism in chronic renal failure

From 1972 to 1987, 112 parathyroidectomy (PTX) operations were carried out in 105 haemodialysis or transplant patients by the same surgeon. Twelve had to be reoperated on (19 operations in all) for persistent (9 cases) or recurrent (3 cases) hyperparathyroidism. In six patients morphological tests (echography and technetium-thallium scintigraphy) contributed usefully by detecting parathyroid masses. Repeated surgery was finally effective in nine cases.
