Hysteroscopy is a procedure used to view the inside of the uterus through a telescope-like device called a hysteroscope. Hysteroscopy offers a valuable extension to the gynecologist’s armamentarium. It can improve the diagnostic accuracy and can permit better treatment of uterine diseases. The hysteroscope is placed in the vagina and introduced into the uterus. A hysteroscope is introduced in a sheath that provides an inflow and outflow channel for insufflation of the uterine cavity. In addition, an operative channel may be present to introduce scissors, graspers, or biopsy instruments. A hysteroscopic resectoscope is similar to a transurethral resectoscope and allows entry of an electric loop to shave off tissue, for instance, to eliminate a fibroid. A contact hysteroscope is a hysteroscope that does not use distension media.
