Correlation between hysteroscopy findings in patients with hydrosalpinx and chronic endometritis.

Objective To evaluate the role of hydrosalpinx in the susceptibility of chronic endometritis (CE). Methods This is a retrospective cohort study, which includes 624 patients with hydrosalpinx (group A) and 789 patients without hydrosalpinx (group B) undergoing laparoscopy and hysteroscopy simultaneously. Endometrial morphology was recorded under hysteroscopy. Endometrial biopsy was obtained after hysteroscopy, and immunohistochemical staining for syndecan-1 (CD138) was carried out. Results No significantly statistical differences were found between the two groups when comparing the incidence of endometrial hyperemia or endometrial micro-polyps under hysteroscopy (P>0.05). Hydrosalpinx had a significant impact on the incidence of CE (P 0.05). Conclusion The presence of hydrosalpinx increased the incidence of CE. Bilateral hydrosalpinx did not significantly increase the incidence of CE compared with unilateral hydrosalpinx.
