In patients with dysfunctionnal uterine bleeding, endometrial hypertrophy or endometrial hyperplasia without atypie, the curettage is the only surgical conservative treatment which allows preservation of fertility. Its efficacy is limited to about 50%. In women without wish for further childbearing, endometrial destruction techniques are effective with high satisfaction levels. Second generation devices should be preferred because they are as effective as first generation techniques, but are easier and faster to perform with less complications. There is no indication for systematic use of pre operative thinning agents. Endometrial destruction techniques are an alternative to hysterectomy that should be offered to women with heavy menstrual bleeding, because there are shorter operation time and hospital stay, earlier recovery and reduced post operative complications. The possibility of further surgery should however be discussed pre-operatively. In case of hysterectomy, abdominal route is not recommended, and vaginal or laparoscopic routes are preferred.
