Evidence - Supracervical hysterectomy, bilateral salpingectomy, laparoscopic

Benign Conditions: Uterine fibroids (~50%), abnormal uterine bleeding (~40%), pain (e.g., in endometriosis/adenomyosis (~30%) or pelvic inflammatory diseases), uterine prolapse (~18%), 

Malignant Conditions: Cervical, endometrial, ovarian cancer, and pre-invasive diseases.

There are conservative and surgical alternatives to hysterectomy, depending on the underlying condition. For example, uterine fibroids can be treated with uterine artery embolization and myomectomy. Pelvic organ prolapse can be managed with conservative therapies such as pelvic floor exercises or pessaries. Chronic pelvic pain can be managed through pain control interventions, including hormonal therapy. Heavy menstrual bleeding can be treated with medical therapies, endometrial ablation, or intrauterine devices. Endometriosis and endometrial hyperplasia can often be treated medically, while cervical intraepithelial neoplasia may be adequately treated by conization.
