Brief Summary

Induction of labor is frequently performed in all obstetric clinics. Failed IOL has been defined in many different ways.Bishop scoring, which is a traditional and subjective method, is more frequently evaluated with cervical length, which has taken its place in preterm labor, and various ultrasonographic evaluations such as Uterocervical angle (UCA), Posterior cervical angle (PCA), cervical elastography, transvulvar ultrasonography, which have recently increased in popularity, have gained importance and led us to evaluate these parameters in our clinic. The relationship between the angles between the uterus and cervix and labor has been known for some time.

Detailed Description

Induction of labor is frequently performed in all obstetric clinics for various indications, with a worldwide spectrum ranging from 1.4 to 35%. Failed IOL has been defined in many different ways. It has been defined as a dilatation of less than 4 cm despite administration of oxytocin for 12 hours±3 hours (target 200-225 MVU or 3 contractions/10 min), induction of labor with oxytocin for at least 12-18 hours (after rupture of membranes) and a latent phase lasting 24 hours or longer, primarily considering fetal and maternal well-being. In some sources, it is defined as failure to achieve regular (e.g. every 3 minutes) uterine contractions and cervical changes with artificial rupture of membranes after at least 6-8 hours of oxytocin maintenance dose. For this reason, various subjective \& ultrasonographic parameters used to predict induction success are of great importance for the evaluation of the cervix. Bishop scoring, which is a traditional and subjective method, is more frequently evaluated with cervical length, which has taken its place in preterm labor, and various ultrasonographic evaluations such as Uterocervical angle (UCA), Posterior cervical angle (PCA), cervical elastography, transvulvar ultrasonography, which have recently increased in popularity, have gained importance and led us to evaluate these parameters in our clinic.

The relationship between the angles between the uterus and cervix and labor has been known for some time.
