The main objective of our study was to analyze the role of ultrasound parameters in the prediction of failure of induction of labor.\nMethods: This was a prospective observational study performed in a tertiary care maternity. For all the women who met our inclusion criteria, we measured these ultrasound parameters: Cervical length (CL), cervical dilation, cervical posterior angle (CPA), fetal head-perineum distance (FHPD), fetal occiput position, biparietal diameter (BPD) and estimated fetal weight (EFW). We defined failure of induction of labor as the occurrence of a cesarean section at any moment after the start of the induction.\nResults: we collected 150 cases of induction of labor that met our inclusion criteria. Failure of induction rate was 45 %. Ultrasound parameters that were significantly associated to failure of induction were Cervical length (p=0.003), cervical dilation (p=0.002), cervical posterior angle (p&lt;10-3), fetal head-perineum distance (p&lt;10-3) and estimated fetal weight (p=0.006). Multivariate regression analysis found that posterior cervical angle and fetal head-perineum distance were the variables independently affecting the outcome of the induction of labor with respective thresholds of 105\u00b0 and 55mm.\nConclusion: Ultrasound can be very useful in predicting the failure of labor induction. The threshold values that we found should be tested and validated in future studies to create a model to predict failure of labor.\u00a0<\/jats:p>","DOI":"10.62438\/tunismed.v103i6.5612","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T16:51:34Z","timestamp":1765903894000},"source":"Crossref","is-referenced-by-count":0,"title":["Role of ultrasound parameters in the prediction of failure of induction of labor using Dinoprostone"],"prefix":"10.62438","volume":"103","author":[{"given":"Hana","family":"Hakim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khaled","family":"Trigui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yosra","family":"Mejdoub","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahma","family":"Ben Msarra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hayfa","family":"Ghaoui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Derbel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kais","family":"Chaabane","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"31112","published-online":{"date-parts":[[2025,6,1]]},"container-title":["La Tunisie M\u00e9dicale"],"original-title":[],"deposited":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T16:51:34Z","timestamp":1765903894000},"score":1,"resource":{"primary":{"URL":"https:\/\/latunisiemedicale.com\/index.php\/tunismed\/article\/view\/5612"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6,1]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2025,6,1]]}},"URL":"https:\/\/doi.org\/10.62438\/tunismed.v103i6.5612","relation":{},"ISSN":["2724-7031","0041-4131"],"issn-type":[{"value":"2724-7031","type":"electronic"},{"value":"0041-4131","type":"print"}],"subject":[],"published":{"date-parts":[[2025,6,1]]}}}
