PURPOSE OF THE STUDY
To substantiate the use of shear wave ultrasound elastography in assessing the state of uterine structures in women of reproductive age with secondary infertility.
MATERIALS AND METHODS
The main group (n=169) consisted of reproductive age patients with secondary infertility, who were divided into two subgroups: 68 women with genital tuberculosis involving the endometrium and 101 women with chronic endometritis without concomitant tuberculosis. The control group (n=45) were healthy women. The average age in the main group was 34.4±2.6 years, in the control group — 32.9±3.1 years. The duration of secondary infertility in N1 was 5.7±1.7 years. All the patients underwent ultrasound examination according to the shear wave elastography (2DSWE) protocol — two-dimensional shear wave elastography with elastometry (Aixplorer scanner, SuperSonic Imagine, France) per vaginam.
RESULTS
According to 2DSWE data It was found that in healthy women of reproductive age the stiffness of the endometrium (Emean 16.5 kPa; SD 1.0) had lower values than that of the endocervix (Emean 23.2 kPa; SD 1.9), (p<0.05). Myometrium stiffness in the cervical region was higher than that in its body (Emean 28.3 kPa; SD 3.0 and Emean 22.3 kPa; SD 1.7, respectively; p<0.05). At this, no potential dependence on different phases of the menstrual cycle was revealed. In patients suffering from secondary infertility with diffuse endometrial pathology, the values of endometrial stiffness were of the greatest diagnostic value and statistical significance. In large values of Young modulus of elasticity for endometrial stiffness exceeding normal values and inconsistent with the phase of a woman’s monthly cycle, and persisting for a long time without significant changes, there was a greater risk of non-conception.
CONCLUSION
The technology of two-dimensional shear wave elastography with elastometry can become an alternative opportunity for timely diagnosis of diffuse endometrial pathology in patients of reproductive age suffering from secondary infertility.
