Diagnostic hysteroscopy directly visualizes the uterine cavity (its size and shape). Thanks to hysteroscopy, it is also possible to evaluate the fallopian tubes and endometrium (the mucosa that lines the uterine cavity). The procedure also allows for the diagnosis of abnormalities in the form of adhesions within the uterine cavity, atresia of the fallopian tubes, endometrial hyperplasia (including endometrial polyps), the presence of uterine fibroids penetrating the uterine cavity, and the diagnosis of some types of uterine malformations. Diagnostic hysteroscopy is usually performed under local anesthesia. Microcamera is inserted into the uterine cavity during the procedure.
