To evaluate the surgical outcomes of parathyroidectomy (PTx) for secondary hyperparathyroidism (SHPT) resistant to calcimimetic treatment, we retrospectively studied 187 patients with SHPT who had no history of calcimimetic treatment (NCMT) (NCMT group) and 186 patients with SHPT who were resistant to calcimimetic treatment (RCMT) (RCMT group). Success rate and operative time of PTx were compared among the two groups. Operative time was significantly longer in the RCMT group than in the NCMT group (180 vs 158 minutes, P < .001), but the difference was attenuated after multivariate adjustment including the weight of the largest parathyroid gland. No significant differences were observed in success rate of PTx (90.9% vs 91.4%, P = 1.000) between the two groups. In patients with SHPT who are resistant to calcimimetic treatment, operative time could be elongated but success rate of PTx remains unchanged.
