Comparative analysis of hysterosalpingography and hysterosalpingo-contrast sonography for assessing tubal patency in women with endometriosis-related infertility: a propensity score-matched study
摘要
This study aimed to compare the clinical pregnancy rates of hysterosalpingography (HSG) with water-based contrast and hysterosalpingo-contrast sonography (HyCoSy) to investigate their impact on fertility outcomes in women with endometriosis-related infertility.
MethodsThis retrospective study included 296 women with endometriosis-related infertility, aged 18–39, undergoing HSG or HyCoSy at the First Affiliated Hospital of Guangxi Medical University (January 2020–June 2022). Propensity score matching was applied to balance demographic and clinical variables. Clinical pregnancy outcomes were compared between the groups.
ResultsThe HSG group showed a higher clinical pregnancy rates compared to the HyCoSy group. Logistic regression demonstrated an odds ratio (OR) of 0.41 (95% CI 0.20–0.82, p < 0.001) for clinical pregnancy in the HyCoSy group compared to HSG. After propensity score matching, the OR was 0.37 (95% CI 0.18–0.75). Similar results were observed across multivariable and IPTW analyses, suggesting that HSG may be associated with better clinical pregnancy outcomes than HyCoSy.
ConclusionHysterosalpingography (HSG) with water-based contrast appears to be associated with higher clinical pregnancy rates compared to HyCoSy in women with endometriosis-related infertility. This suggests that HSG may be a more favorable diagnostic method for optimizing fertility outcomes, though further research is needed to confirm these findings.
