Depending on whether the procedure is to investigate or treat a problem, a hysteroscopy usually takes between 10-30 minutes. Your gynaecologist will pass the hysteroscope through your vagina and into your womb. This can normally be done without anaesthetic or with local anaesthetic. However, for some procedures involving treatment, you may have a general anaesthetic. A hysteroscopy that includes removing fibroids usually takes between 30-60 minutes. Your gynaecologist or specialist nurse will pass the hysteroscope through your vagina and into your womb. They will then use small instruments passed though the hysteroscope to remove the fibroids. You will usually be under general anaesthetic during the procedure.
