Diagnostic hysteroscopy is the endoscopic examination of the uterine cavity and its internal features. It has long been established as the principal investigation into the causes of abnormal uterine bleeding. Typical findings might include the presence of intracavital lesions (eg endometrial polyps, fibroids or adhesions), abnormal development of the endometrium or congenital anatomical malformation of the uterus and/or cavity.

The hysteroscope is essentially a long, narrow camera tube specifically designed to be inserted through the cervical canal. It contains an internal channel which allows saline to be flushed through the hysteroscope into the uterine cavity. Introduction of the saline separates the walls of the uterine cavity. Fibre optic elements within the hysteroscope provide direct visualisation into the distended cavity.
