Use of Monitoring Intraoperative Parathyroid Hormone During Parathyroidectomy in Patients on Waiting List for Renal Transplantation

Abstract

This report describes the use of intraoperative parathyroid hormone (ioPTH) assay during parathyroidectomy for patients with secondary hyperparathyroidism on the waiting list for renal transplantation. The levels of ioPTH were determined among waiting list patients undergoing subtotal parathyroidectomy and tertiary hyperparathyroidism patients undergoing procedures. The levels of ioPTH were significantly reduced at 10 minutes by 59.7,3% among with secondary hyperparathyroidism and 68.9% among tertiary hyperparathyroidism. A 15 minutes it was 85% in secondary hyperparathyroidism and 89.7% in tertiary hyperparathyroidism. A decrement of 50% in basal values at 10 minutes and 85% decrement or more at 15 minutes was predictive for the success of abnormal parathyroid gland removal. The application of this technique during subtotal parathyroidectomy results was useful to predict a correct excision of abnormal parathyroid glands among patients with secondary hyperparathyroidism on the waiting list and for tertiary hyperparathyroidism patients
