RESUMEN
OBJECTIVES: The purpose of the study was to assess the accuracy of hysterosalpingo-contrast sonography (HyCoSy) for evaluation of the uterine cavity. METHODS: Hysterosalpingo-contrast sonography was compared with hysteroscopy for assessment of the uterine cavity. This work was a descriptive prospective study to assess the concordance between pathologic intrauterine findings using the Cohen κ coefficient. Ninety infertile patients from Puerta de Hierro University Hospital were included in the study. They underwent HyCoSy between June 2016 and April 2017. Fifteen of them had pathologic findings in the uterine cavity during HyCoSy and therefore underwent hysteroscopy. Clinical and sonographic findings were compared in those 15 patients by to evaluate the agreement between both techniques. RESULTS: In this study, intrauterine sonographic findings on HyCoSy and hysteroscopic features of the uterine cavity reached 100% concordance, with a κ coefficient of 1.000 and a 100% agreement rate. CONCLUSIONS: Hysterosalpingo-contrast sonography permits a very accurate evaluation of the uterine cavity, which could be of interest for infertile patients who might be examined for tubal patency.
