[Comparison between hysterosonography and hysterosalpinography in the study of endometrial abnormalities in infertility patients]. / Comparación entre histerosonografía e histerosalpingografía en el estudio de anormalidades endometriales en pacientes con esterilidad.

OBJECTIVE: We compare effectiveness between HSS and HSG for detection of endometrial abnormalities among patient with infertility. DESIGN OF THE STUDY: Prospective, cross section, comparative. MATERIAL AND METHODS: 33 patients were studied. HSS and HSG were carried out. The images of both studies were compared, settled down a presumptive diagnosis of normality or abnormality. The analysis included percentage of agreement, coefficient of agreement Kappa, square Ji, reason of verisimilitude. RESULTS: Of 33 studied patients was diagnostics correlation in 17 (52%). The pathologies with more correlation were congenital malformations and submucous miomas, with less correlation were adherences. Other opposing pathologies were polyps and corioplacentary remains. In 9 patients (27%) we find normality in both studies. When comparing the positive studies in each group we don't find differs statistically significant (P > 0.05). The association among both techniques was high (K = 0.70). The reason of verisimilitude of the tests was 98% for HSS and 90% for HSG. CONCLUSIONS: Both studies are useful to evaluate the uterine cavity. However histerosonography has bigger sensibility and specificity, besides is a quick, easy, and economic study, with less discomfort and complications than histerosalpingography.
