    Abstract:
    BACKGROUND/AIMS: The short- and long-term impact of parathyroidectomy (PTX) on the parameters of mineral bone disease in dialysis patients with severe secondary hyperparathyroidism (HPT) remains unclear. METHODS: A retrospective chart review of 401 consecutive dialysis patients who underwent subtotal PTX by one surgeon was performed. We checked serum levels of calcium (Ca), phosphorus (P), and intact parathyroid hormone (iPTH) for 3 consecutive days, and then monthly for Ca, P, and tri-monthly for iPTH postoperatively. Patients with available laboratory data within the 1st to 6th postoperative months were included in the short-term follow-up group and those with at least 6 months available data were in the long-term follow-up one. RESULTS: Patients (short-term group, n = 401, and long-term group, n = 94) had severely uncontrolled serum iPTH levels, Ca, P and Ca × P before PTX. In the short-term group, percentages of cases achieving K/DOQI targets for serum Ca, Ca × P, and iPTH and KDIGO ones for serum Ca, P, and iPTH after PTX, significantly improved compared with those before operation (all p < 0.05). In the long-term group (mean follow-up of 43 ± 29 months), the percentage of achieved targets for serum iPTH in both guidelines and for serum Ca and Ca × P in the K/DOQI recommendation also improved postoperatively (all p < 0.05). CONCLUSIONS: Achievements of K/DOQI recommended values for serum Ca, Ca × P, iPTH and KDIGO recommendations for iPTH can be successfully reached by subtotal PTX in medically refractory, secondary HPT in dialysis patients both during short- and long-term follow-ups.
