Abstract:
【Objective】To investigate a new method for assessing the intrauterine adhesion（IUA）by three- dimensional（3D） endometrial area imaging. 【Methods】 A total of 121 women with suspected IUA or tubal factor infertility undergoing hysteroscopy were enrolled in this retrospective study. The patients were divided into two groups ：those with IUA and those without IUA. The endometrial area cutoff point was calculated to classify the patients with IUA into mild ， moderate ，and severe subgroups according to their AFS classification. 【Results】 When IUA were diagnosed based on the endometrial area，the area under the receiver operating characteristic（ROC）curve was 0.839，the cutoff point was 4.23 cm2，the sensitivity was 0.86，and the specificity was 0.74，the diagnostic efficiency is 76.03%. We further classified IUA into mild，moderate，and severe groups based on the endometrium area as follows：mild IUA（4.02，4.23］cm2，moderate IUA（3.23 ，4.02］cm2 ，and severe IUA≤3.23 cm2. The incidence rate of IUA increased by 30.6% for each one-unit decrease in abortive gestational age and increased by 18.9% for each one-unit decrease in endometrial area.【Conclusion】3D endometrial area imaging is a simple and fast tool for IUA diagnosis and severity assessment，providing a new diagnosis method for gynaecologists to assess IUA.
