Cervical Stenosis Definition:
Cervical stenosis is a condition in which the cervical canal is narrow or in severe cases completely obstructed.
Causes:
- Cervical Conization: a procedure used to remove a portion of the cervix when cancer / pre-cancer is diagnosed. It is a testing and often curative procedure.
- Cryotherapy
- Cervical Cerclage: a procedure where sutures are used to close the cervix to reduce the risk of preterm delivery.
- Any surgery involving the cervix including ablation.
- Recurrent Vaginal Infections.
Symptoms:
- Worsening dysmenorrhea (painful periods)
- Light menstrual flow
- Long duration of menstrual flow
- Amenorrhea (no menstrual flow seen): is rare, but when the cervix is completely blocked no menstrual flow is visualized.]
Treatment & Diagnosis:
Diagnosis: is often made by the history of the patient followed by uterine sounding and dilation (mechanically opening the cervical canal with dilators). An ultrasound can also be helpful in determining the diagnosis. With severe cervical blockage the ultrasound often reveals Hematometra (blood collecting in the uterus).
Treatment: often cervical dilation alone is adequate. In severe cases a catheter is often left in the cervix for 1-2 weeks. The catheter prevents re-closure of the cervix and ensures that blood in the uterus can drain.
