Ultrasound-guided high intensity focused ultrasound for the treatment of gynaecological diseases: A review of safety and efficacy.

As a non-surgical treatment, high intensity focused ultrasound (HIFU) has received increasing interest for the treatment of gynaecological diseases over the last 10 years. Many studies have shown that HIFU is safe and effective in treating patients with uterine fibroids, adenomyosis, cervicitis or vulvar diseases. Both magnetic resonance imaging-guided HIFU (MRgHIFU) and ultrasound-guided HIFU (USgHIFU) can offer gynaecologists non-invasive techniques to treat patients with uterine benign diseases. Focused ultrasound therapy can also be used effectively to treat cervicitis and vulvar diseases. As gynaecologists gain more experience with this technology, the rate of severe adverse effects has been lowered with the development of this non-invasive technique. In this paper we review the literature available regarding the utilisation of magnetic resonance imaging-guided focused ultrasound/MRgHIFU or USgHIFU and new findings from our group in the treatment of gynaecological diseases: uterine fibroids, adenomyosis, cervicitis, vulvar diseases, caesarean scar pregnancies, and abdominal wall endometriosis.
