[Comparative study of diagnostic hysteroscopy and transvaginal ultrasonography in patients with abnormal uterine hemorrhage during the peri- and post-menopausal period].

Background: The aim of this study was to determine the diagnostic value of hysteroscopy and transvaginal ultrasonography in patients with abnormal uterine bleeding (AUB) in the peri and postmenopausal period.
Methods: 302 patients with AUB, underwent hysteroscopy and in 86 cases, also a transvaginal ultrasonography before hysteroscopy was performed. Results were compared with the histological diagnosis.
Results: The diagnostic accuracy of hysteroscopy was very high in the cases of endometrial carcinoma (sensibility 100%, specificity 99%), and lower in the cases of endometrial hyperplasia (sensibility 69%, specificity 72%) and endometrial atrophy (sensibility 29% and specificity 97%). Sonography proved to be less reliable in the diagnosis of endometrial pathology (carcinoma: sensibility 57%, specificity 100%, hyperplasia: sensibility 62.5% specificity 63%). The results of this study show that sonography may be used as a first choice diagnostic test in the investigation of women with AUB.
Conclusions: Hysteroscopy represent a second diagnostic step for achieving a proper histologic diagnosis.
