aid of the “proliferative test” with ovestine.

Use of the transvaginal US study enabled one to investigate into the endocervix condition, its thickness, echo-structure, surrounding stroma of the cervical canal, and to visualize contours of the CU vaginal segment in its whole extent. The cervix of the uterus with no pathological changes during the US study in the postmenopause patients has the shape of cylinder, even external contours, the same thickness of anterior and posterior walls, homogeneous structure comparable by its echogenicity with the echogenicity of the uterus body myometrium. The CU M-echo occupies central position and is an imaging of the cervical canal and surrounding subepithelial segments of the cervix of the uterus that are isoechogenic to the surrounding stroma. In the EDC of the tissues adjacent to the endocervix, singular loci of blood flow may be observed.

We have determined various types of the endocervix visualization depending on the postmenopause duration under normal conditions. In 73,7% of the patients with the postmenopause duration under five years, the CU M-echo was visualized in the form of a hyperechogenic strip of thickness up to 1-2 mm, with homogeneous structure that was a reflection of the anterior and posterior walls of the cervical canal mucous membrane. In the patients with the postmenopause duration over five years, in 66% of cases, the CU structure was homogeneous, the imaging of the M-echo was absent.  

In endocervicitis, irrespective of the postmenopause duration, the echography in 100% revealed extension of the M-echo width for over 4.5 mm on account of enlargement of the cervical canal for over 2 mm with accumulation of liquid content in it, as well as inflammatory infiltration of the cervical canal epithelium and the adjacent structures (р<0,01). In 47,1% of cases in endocervicitis, thickening of the cervical canal wall was visualized in the form of a hyperechogenic strip of a 2-3-mm width around the enlarged cervical canal of inhomogeneous structure that can be traced in fragment. In 32,4% of cases, the hypoechogenic area of 3 to 10 mm width around the cervical canal enlarged on account of inflammatory infiltration around the unevenly thickened wall of the cervical canal, was visualised. When assessing the
