Endometrial ablation is a procedure that destroys (ablates) the uterine lining, or endometrium. This procedure is used to treat dysfunctional or abnormal uterine bleeding. Sometimes a lighted viewing instrument (hysteroscope) is used to see inside the uterus. Endometrial ablation can be done by:

    -Laser beam (laser thermal ablation).

    -Heat (thermal ablation), using:
         *Radiofrequency.
         *A balloon filled with saline solution that has been heated to 85°C (185°F) (thermal balloon ablation).
       *Normal saline (heated free fluid).

    -Electricity, using a resectoscope with a loop or rolling ball electrode.                                                                                                                                                                                                                                              

The endometrium heals by scarring, which usually reduces or prevents uterine bleeding.
