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.
