Description:
Impedance-controlled bipolar radiofrequency ablation is used to treat heavy menstrual periods, also known as menorrhagia.
Menorrhagia is a very common problem. Hysterectomy has been the standard treatment for women with menorrhagia who have not responded to medical treatment. Minimally invasive procedures to destroy the lining of the uterus (the endometrium) are alternatives to hysterectomy. They involve destroying the endometrium using lasers, radiofrequency waves, electrocautery, microwaves, heated saline, or a heated balloon. Impedance-controlled radiofrequency ablation is one of these minimally invasive procedures.
Under general or local anaesthetic, a sheath containing a bipolar radiofrequency electrode is placed through the cervix. This sheath is pulled back, allowing the electrode to expand and conform to the shape of the uterine cavity. Radiofrequency energy is then delivered into the uterus via the electrode. The electrode is then retracted back into the sheath and removed from the uterus. No endometrial pre-treatment is necessary.
Fibroids or large polyps inside the cavity of the uterus may interfere with the placement of the device.
