Surgical outcome of primary hyperparathyroidism and factors correlated with preoperative serum iPTH concentration

Parathyroidectomy yields favorable biochemical outcomes in patients with PHPT and remains the most effective strategy for preventing disease progression. Tumor size was the only factor associated with elevated preoperative iPTH levels. Persistent postoperative iPTH elevation in some patients underscores the importance of early diagnosis and timely surgical intervention, particularly before irreversible systemic complications arise.
