When Medical Treatment Fails to Control PTH in Secondary Hyperparathyroidism
In secondary hyperparathyroidism, medical management is the first-line approach. When it does not bring intact PTH within the accepted target range for stage 5D chronic kidney disease, a defined next-line protocol applies.
Prior Line — Failure Condition
Medical treatment with phosphorus binders combined with a PTH-lowering agent — a calcimimetic (cinacalcet, etelcalcetide hydrochloride, or evocalcet), calcitriol, or vitamin D analogs — did not achieve an intact PTH within the target range of 130–600 pg/mL in stage 5D CKD.
Next-Line Approach (partial overview)
Parathyroidectomy is the recommended surgical intervention when medical therapy has failed. Which procedure is appropriate depends on the patient's expected renal replacement trajectory — the full protocol specifies the approach for each clinical situation.
Clinical goal: Successful parathyroidectomy is defined as an intact PTH level <60 pg/mL on postoperative day one. Full criteria and management details are within the complete protocol.

- Therefore, parathyroidectomy (PTx) is the radical surgical treatment for severe SHPT.
- PTx is recommended when medical therapy has failed.
- We previously showed that a 70% decrease in intact PTH 10 minutes after total PTx and transcervical thymectomy can predict successful PTx, defined as an intact PTH level <60 pg/mL on postoperative day one.
