2. MWA treatment
1 or 2 microwave antennas were placed inside the UFs by US-guidance percutaneous puncture, microwave output energy was set at (50 or 60) W, and then, started MWA therapy for UFs (Fig.1). For patients with sexual life, a hysterosalpingography catheter (Fig.2) was inserted into the uterine cavity 5 minutes before treatment to identify the position of endometrium during treatment; when ablating FIGO 0–4 UFs, cool normal saline was injected into the uterine cavity to form water isolation to prevent heat damage to the endometrium.
