Overview: Abnormal uterine bleeding is a common gynecological symptom. The curettage can asses only 50-60% of endometrium surface, thereby leaving some changes unrevealed. Sonohysterography (SHG), which combines the distention of the uterine cavity trough saline solution and ultrasound examination, allows a more exact evaluation of uterine cavity abnormalities.
Objectives: To assess the value of sonohysterography in the diagnosis and management of abnormal uterine bleeding.
Materials and methods: 67 women with abnormal uterine bleeding and uterine cavity abnormalities confirmed by transvaginal ultrasound were examined with sonohysterography.
Results: Sonohysterography revealed 21 cases of submucous myomas, 22 endometrial polyps and 24 cases of endometrial hyperplasia. All patients underwent diagnostic hysteroscopy to verify the results. The sensitivity and specificity for sonohysterography were both 93%. The positive and negative predictive values were 96% and 93%, respectively.
Conclusions: Sonohysterography is a sensitive and specific method for diagnosis of abnormal uterine bleeding. It allows faster and less invasive diagnosis. Given the low costs of examination sonhysterography can be used as an ambulatory procedure reducing delay of treatment.
