Operative hysteroscopy is a minimally invasive gynecological procedure in which an endoscopic optical lens is inserted through the cervix into the endometrial cavity to direct treatment of various types of intrauterine pathology. Hysteroscopy is a procedure to look into uterus in order to diagnose and treat causes of abnormal bleeding. Hysteroscopy is done by using a hysteroscope, a thin, lighted tube that is inserted into the vagina to examine the cervix and inside of the uterus. Operative hysteroscopy is worn to find the cause of ruthless cramping or abnormal bleeding. To stop the bleeding can use heated tools through the hysteroscopy and to see whether a problem in the shape or size of the uterus or if scar tissue in the uterus is the cause of infertility.
