Introduction. Induction of labor is one of the most common obstetric interventions in contemporary obstetrics. Objective. The aim of the study was to evaluate the clinical and sonographic parameters in prediction of success of labor induction. Methods. The prospective study included 422 women in whom induction of labor was carried out at the Department of Obstetrics and Gynecology of Clinical Centre of Vojvodina. The role of body mass index and age of women, parity Bishop score, cervical length measured by transvaginal ultrasound was evaluated in regard of the success of induction, which was considered successful if a vaginal delivery occurred within 24 hours after the onset of induction. Data were statistically analyzed by univariate statistical analysis and Pearson’s χ2 test. Results. Out of 422 women, induction of labor was successful in 356 (84.4%), and it failed in 66 (15.6%) cases. The values of Bishop score and cervical length had positive correlation with the success of induction. Conclusion. Bishop score and transvaginal cervical length were both reliable predictors in determining the success of labor induction, as well as parity and BMI. These parameters are mostly complementary, not competitive in prediction of labor induction success.
