SALAZAR MORA, Ronald  and  CALDERON ZUNIGA, Alberto. Ultrasonografía transvaginal e histerosonografía en el diagnóstico de patologías endometriales. Acta méd. costarric [online]. 2001, vol.43, n.4, pp.175-177. ISSN 0001-6002.

Justification and objectives: In spite than in the last year the vaginal ultrasound has become a powerful tool in the evaluation of patients with abnormal uterine bleeding, it has shown some limitations for the diagnosis of endometrial pathology. Intracavitary saline infusion during the ultrasonographic procedure, has shown to be a more sensitive method. Our main objetive was to compare the sensitivity and specificity of the vaginal ultrasound versus the histerosonography in the diagnosis of various endometrial pathologies. Methodology: In this study, 36 patients with the diagnosis of abnormal uterine bleeding were selected consecutively as they were refered for vaginal ultrasound. All of them had vaginal ultrasound and then histerosonography, comparing the results with the histologic diagnosis as the "gold estandar". Results: Thirty eight oercent had normal endometrium 30% had endometrial polyp, 305 had endometrial hyperplasia, 19% intramural myomas and/or adenomyosis, and submucus myomas were found in 7.6% of the patients. The sensitivity and specificity for the vaginal ultrasound was 42.8% and 91.6% and for the histerosonography were 92.8% y 100% respectively. Were conclude that histerosonography was more precise in the diagnosis of endometrial pathology in patients with abnormal uterine bleeding.
