Ultrasonographic parameters of XXXX in correlation with the outcome of early medical abortion.

@entity1 @entity2318 @entity396 @entity177 @entity3927
OBJECTIVE: To determine whether @entity2318 ( @entity2318 ) parameters assessed by transvaginal sonography (TVS) might impact the early medical abortion outcome. METHODS: @entity1 with previous cesarean delivery who received oral @entity3927 and @entity396 for medical abortion were reviewed retrospectively. A successful medical abortion was defined as the absence of intrauterine gestational sac and without surgical intervention. @entity2318 was diagnosed in the presence of a hypoechogenic indentation within the myometrium of the lower uterine segment at the site of a previous cesarean incision by TVS. The ratio of the remaining myometrium thickness over the defect and the adjacent myometrial thickness was divided into three groups (<30%, 30%-70%, and >70%). RESULTS: Of 183 @entity1 , 43 (23.5%) had medical @entity177 , 59 (32.2%) with detectable CSDs had a higher failure rate than those without CSDs (38.9% vs. 16.1%; P   =   0.001). CSDs were significantly associated with medical @entity177 (OR   =   3.32, 95% CI: 1.63-6.75). The failure rates in relation to the defect size in the <30%, 30%-70%, and >70% groups were 57.1%, 25.0%, and 18.2%, respectively. A linear trend was observed in failure rates of medical abortion across these ratios (Cochran-Armitage trend test; P   =   0.015). CONCLUSIONS: @entity1 with @entity2318 are at increased risk of failed medical abortion. @entity1 with a defect with the remaining myometrium less than 30% of the adjacent myometrial thickness tended to have higher failed medical abortions. Detectable @entity2318 is of clinical relevance in counseling @entity1 with history of cesarean deliveries for medical abortion.
