Hysteroscopy is a procedure that can be used to both diagnose and treat causes of abnormal bleeding. The procedure allows your doctor to look inside your uterus with a tool called a hysteroscope. This is a thin, lighted tube that is inserted into the vagina to examine the cervix and inside of the uterus. Hysteroscopy can be a part of the diagnosis process or an operative procedure. Hysteroscopy can be used with other procedures, such as laparoscopy, or before procedures such as dilation and curettage (D&C). In laparoscopy, your doctor will insert an endoscope (a slender tube fitted with a fiber optic camera) into your abdomen to view the outside of your uterus, ovaries and fallopian tubes. The endoscope is inserted through an incision made through or below your navel.

Polyps and fibroids: Hysteroscopy is used to remove these non-cancerous growths found in the uterus.
Septums: Hysteroscopy can help determine whether you have a uterine septum, a malformation (defect) of the uterus that is present from birth.
Abnormal bleeding: Hysteroscopy can help identify the cause of heavy or lengthy menstrual flow, as well as bleeding between periods.
Adhesions: uterine adhesions are bands of scar tissue that can form in the uterus and may lead to changes in menstrual flow as well as infertility.
