[Transvaginal ultrasonography and sonohysterography in the diagnosis of benign uterine lesions in women at peri- and postmenopausal age].

Abnormal uterine bleeding is important clinical problem in women at peri- and postmenopausal age. It may be caused by the lesions located in endometrium or in deeper uterine wall layers. An aim of this paper was a comparison of transvaginal sonography (TVS) vs. sonohysterography (SIS) in the diagnostics of endometrial polyps, endometrial hyperplasia as well as uterine myomas. Also the results of the sonographic imaging were compared to those of pathologic examination of the specimens taken from the uterine cavity. The material consisted of 100 women aged 40-80 with an irregular menstruation. All of the patients were examined gynecologically, and then the transvaginal sonography, sonohysterography and the curettage of the uterine cavity were performed. Sensitivity of TVS was 43% in endometrial polyps, 77% in endometrial hyperplasia and 69% in uterine myomas imaging. Introduction of SIS increased the sensitivity to 94%, 82%, and 95%, respectively. Specificity was similar in both techniques except endometrial hyperplasia (TVS--68%, SIS--91%). Diagnostic accuracy also improved with the SIS use reaching 93% for polyps, 89% for hyperplasia and 98% for myomas imaging. Our results show higher sensitivity and accuracy of SIS in the diagnostic of benign uterine lesions.
