Endometrial Radiofrequency Ablation (NovaSure®)


During this procedure, which takes about 30 minutes to complete, the physician uses a radiofrequency device to destroy the endometrial lining of the uterus. This procedure is an effective method for the treatment of abnormal vaginal bleeding, especially heavy menstrual bleeding.


In preparation for the procedure, the patient is positioned and anesthesia is administered. Local or regional anesthesia is most commonly used, but in some cases twilight sedation or general anesthesia may be used. The physician inserts a speculum into the vagina to allow access to the cervix.

Inserting the Device

The physician carefully inserts the NovaSure ablation device through the cervix and into the uterus. The physician then slowly releases the device’s electrode array, which fans out to rest against the uterine walls.

Treating the Uterus

The physician activates the ablation device, releasing radiofrequency energy from the electrode array. This energy cauterizes and destroys the endometrial lining of the uterus.

End of Procedure and Aftercare

When the procedure is finished, the patient will rest briefly in a recovery room and will then be allowed to go home. The physician will provide specific aftercare instructions. In the days after the procedure, a layer of scar tissue will form to replace the destroyed endometrial lining in the uterus. Most women will have little or no menstrual bleeding following the ablation. Because the uterus will no longer be healthy enough to support the proper development of an embryo, effective birth control or sterilization must be used to prevent pregnancy after ablation.
