The role of intraoperative parathyroid hormone testing in patients with tertiary hyperparathyroidism after renal transplantation

Accuracy of intra-operative PTH measurement during subtotal parathyroidectomy for tertiary hyperparathyroidism after renal transplantation

“…After renal transplantation, most of the patients retrieve good renal function; however, the accuracy of IOPTH in patients with tertiary hyperparathyroidism is not known. Previous reports have shown that IOPTH changed the management in 5 of 32 patients studied with only one false positive result; however, the long-term cure rate is given by the calcium level only and not the PTH level in this study [28]. Because of the retrospective nature of our study, the IOPTH did not change the management of any of the 35 patients.…”

Tertiary Hyperparathyroidism Secondary to X-linked Hypophosphatemic Rickets

“…[5][6] In our case, the PTH level dropped from 176 pg/mL to 12 pg/mL. The surgical treatment is already unclear, but it is the only effective treatment.…”

Usefulness of intraoperative parathyroid hormone measurements in patients with renal hyperparathyroidism

“…In the literature, many different criteria of intraoperative PTH decline have been suggested for prediction of postoperative outcome in patients with renal hyperparathyroidism. When using the intact PTH assay, several authors suggest to use the same criterion as in patients with primary hyperparathyroidism (the Miami Criterion of more than 50% decline from the baseline PTH 5 to 10 minutes after excision), 4,9 whereas others point out that higher percentages of decline or absolute values at other time points after excision are necessary.…”
