Transvaginal sonography (TVS) of the cervix is a useful tool to predict prematurity; in the present study, this tool was used to evaluate postterm induction.<\/jats:p><jats:p>Methods\u2003We evaluated the ultrasound characteristics of the cervix (cervical length, cervical funneling, internal os dilation, the presence or absence of the cervical gland area [CGA], and the morphological changes of the cervix as a result of applying fundal pressure) before the onset of labor induction among women with postterm pregnancy to identify the possible predictors of failed labor induction. The Bishop score (BS) was used for comparison purposes. Three groups were evaluated: successful versus unsuccessful induction; vaginal delivery versus cesarean delivery (excluding cases of acute fetal distress [AFD]); and vaginal delivery versus cesarean delivery (including cases of AFD). A fourth group including only the primiparous women from the three previous groups was also evaluated.<\/jats:p><jats:p>Results\u2003Based on the studied characteristics and combinations of variables, a cervical length\u2009\u2265\u20093.0\u2009cm and a BS\u2009\u2264\u20092 were the best predictors of induction failure.<\/jats:p><jats:p>Conclusion\u2003Although TVS is useful for screening for
