This study is aimed to evaluate the clinical safety and effectiveness of Microwave ablation (MWA) in treating patients with uterine fibroid.


Percutaneous radiofrequency ablation (RFA) is another form of thermal ablation that has been used for the treatment of uterine fibroids. Although RFA is more invasive when compared to High-Intensity-Focused-Ultrasound (HIFU), the treatment is less limited by the location of the lesions, and the treatment procedure is more time efficient. To further improve the technology of thermal ablation for uterine fibroid, percutaneous microwave ablation (MWA) could be a promising option because it allows increased efficiency of energy transmission and reduction in procedure time, and may allow effective treatment of large lesions.
