Initial parathyroid surgery in 606 patients with renal hyperparathyroidism.
BACKGROUND
The aim of the present study was to evaluate the outcome of different surgical procedures for patients on permanent dialysis who underwent initial parathyroidectomy for renal hyperparathyroidism (rHPT).


METHODS
Out of a prospective database of patients who underwent parathyroid surgery for rHPT between 1976 and 2009, patients on permanent dialysis who underwent initial parathyroidectomy were further analyzed regarding perioperative biochemical changes and postoperative outcome.


RESULTS
A total of 606 patients were analyzed. Total parathyroidectomy with autotransplantation (group A) was performed in 504 patients, total parathyroidectomy without autotransplantation in 32 (group B), subtotal parathyroidectomy in 21 (group C), and incomplete parathyroidectomy in 49 (group D). After surgery, mean calcium levels dropped from 2.76 to 1.91 mmol/l in group A, from 2.67 to 2.11 mmol/l in group B, from 2.70 to 2.09 mmol/l in group C, and from 2.65 to 1.94 mmol/l in group D. The parathyroid hormone level dropped from 1,371.4 pg/ml to 28.8 pg/ml in group A, from 1,078.4 pg/ml to 27.0 pg/ml in group B, from 2,377.9 pg/ml to 61.4 pg/ml in group C, and from 1,010.2 pg/ml to 99.5 pg/ml in group D. Persistent rHPT occurred in 2/504 patients from group A (0.4%), 0/32 patients from group B (0%), 1/21 patients from group C (4.8%), and 2/49 patients from group D (4.1%). After a mean follow-up of 57.6 months, recurrent rHPT occurred in 27/504 patients from group A (5.4%), in 0/32 patients from group B (0%), in 2/21 patients from group C (9.5%), and in 3/49 patients from group D (6.1%).


CONCLUSIONS
Total parathyroidectomy with or without autotransplantation is a feasible and safe surgical procedure for patients on permanent dialysis with otherwise uncontrollable rHPT.
