Hysteroscopy is a minimally invasive procedure that involves the application of a dilating medium to enlarge the uterine cavity and the insertion of a fiberoptic speculum with a light source through the patient’s cervical orifice, which is used to observe the morphology of the uterine cavity, including the physiological and pathological changes in the cervical canal, the endocervix, the uterine cavity, and the opening of the fallopian tubes. In addition, guided sampling and pathological examination is performed for occupancies with diseased tissue. Hysteroscopy is mainly used for patients with abnormal uterine bleeding, for patients with fertility requirements, for finding the cause of recurrent unexplained infertility, recurrent miscarriages, and for considering the presence of uterine adhesions, uterine malformations, foreign body residues in the uterine cavity, such as pregnancy residues, and the removal of intrauterine devices and vaginal foreign bodies, as well as for imaging examinations suggesting the presence of occupying lesions in the uterine cavity and further uterine cavity Pre- and post-operative evaluation for surgery.
