Hysteroscopy can be considered in the following cases: 1) abnormal uterine bleeding 2) uterine adhesions caused by surgery or infection 3) repeated miscarriages, more than twice 4) abnormal uterine echogenicity and occupying lesions detected by ultrasonography 5) further diagnosis and treatment of abnormal hysterosalpingography, 6) unexplained infertility 6) repeated failed hospitalization 7) positioning or removal of intrauterine devices and foreign bodies in the uterine cavity Several cases in which hysteroscopy cannot be performed Pregnancy, 2, vaginal or urinary tract infection, 3, endometrial cancer. Hysteroscopic procedure: Hysteroscopy is usually performed 3 to 7 days after menstruation, and the pain can be blocked by general anesthesia or local anesthetic before the procedure. If needed, biopsies or other treatments can also be performed under hysteroscopic guidance using small medical devices. Recovery after hysteroscopy: If general anesthesia is used, the patient will need to stay in the hospital for a period of observation until the anesthesia wears off. It is normal to have mild cramping or a small amount of bloody discharge for about a week after the procedure, but if you have a fever or cold or abnormally increased bleeding, please seek immediate medical attention.
