OBJECTIVE This study aimed to analyze the potential correlation between chronic endometritis (CE) and intrauterine adhesions (IUA) with its associated risk factors. PATIENTS AND METHODS We retrospectively analyzed data from 131 patients who underwent hysteroscopic transcervical resection of adhesions (TCRA) for intrauterine adhesions at our hospital between February 2020 and February 2021. General clinical data were collected and analyzed using univariate, multifactorial, and logistic regression analyses. Patients with mild, moderate, and severe IUA were divided into two groups based on whether they coincided with CE (CE group) or not (NCE group). Logistic regression analysis of the factors associated with IUA was performed, and the recurrence rates of IUA after TCRA in the CE and NCE groups were registered. RESULTS The risk of severe IUA was higher in patients with a higher number of abortions, higher number of indolent abortions, and CD138 positivity. In addition, the incidence of IUA combined with chronic CE varied when comparing the different IUA stages: 10.70% (3/28) for patients with mild IUA, 25.00% (7/28) for patients with moderate IUA, and 64.30% (18/28) for patients with severe IUA. The recurrence rates of IUA after TCRA in the CE and NCE groups were 69.20% (9/26) and 30.08% (4/67), respectively, in patients with moderate to severe IUA, and the differences were statistically significant (χ2=12.782, p=0.001). CONCLUSIONS A correlation was observed between CE and IUA. Patients presenting both conditions had more severe IUA stage and higher recurrence rates after TCRA.
