Cervical Stenosis in Postmenopausal Patients When Cervical Ripening Has Not Restored Canal Patency
This protocol applies to women with stricture and stenosis of the cervix uteri who have a postmenopausal status or are receiving gonadotropin-releasing hormone (GnRH) analog therapy — conditions that produce a hypoestrogenic state — and in whom a prior attempt at preprocedural cervical ripening did not achieve the clinical goal of cervical canal patency.
Clinical Scenario
Postmenopausal women and those on GnRH analog treatment are in a hypoestrogenic state. This significantly reduces the effectiveness of standard pharmacological cervical ripening agents, making cervical stenosis particularly challenging to manage in this population.
Previous Approach Did Not Succeed
The preceding treatment step — preprocedural cervical ripening using estrogen pretreatment with misoprostol, or insertion of osmotic cervical dilators — did not restore sufficient patency of the cervical canal to allow dilation. This protocol describes the next step taken in that situation.
Next Step: Treatment Approach
A mechanical approach to cervical dilation is indicated at this stage; the complete regimen, including specific instruments, any adjunct preparatory measure, and monitoring requirements, is detailed in the full protocol.
Clinical Goal
Restoration of the patency of the cervical canal, enabling successful entry into the uterine cavity.

In postmenopausal women and those treated with gonadotropin-releasing hormone analogs, misoprostol has a decreased effect since prostaglandins require estrogen to generate their cervical ripening effects, and postmenopausal patients are in a hypoestrogenic state.
A mechanical option to dilate the cervix is with using Hegar or Pratt dilators.
Vasopressin has been reported to reduce the force required for entry in cases of cervical stenosis when injected into the cervix before the procedure.
Due to its potential cardiorespiratory side effects, vasopressin should only be used for this purpose under cardiac monitoring.
