Abstract:
Objective: To observe the safety and efficacy of ultrasound-guided microwave ablation (MWA) for treatment of patients with secondary hyperparathyroidism (SHPT) after renal transplantation (RT). Methods: Data of 20 SHPT patients after RT who underwent MWA were retrospectively analyzed. The level of intact parathyroid hormone (iPTH), serum calcium, serum phosphorus, creatinine and blood urea nitrogen concentrations before and after MWA were assessed and compared. Results: Complete ablation was achieved in a total of 34 parathyroid nodules among 20 SHPT patients. The mean maximum diameter of parathyroid nodule was (1.41±0.61)cm, and the median ablation time was 219 s. The mean iPTH, serum calcium and phosphorus concentrations after MWA were significantly lower than those before MWA (P<0.05). No significant difference of creatinine nor blood urea nitrogen was found before and after MWA (P>0.05). No major operation-related complication occurred in 20 patients. Conclusion: Ultrasound-guided MWA is a safe and effective method for treating SHPT after RT.
