Objectives: The purpose of this study is to evaluate the effects of isolated oligohydramnios on labor, delivery mode, and its neonatal outcomes. Methods: In this prospective case-control study; we analysed 159 pregnancies with isolated oligohydramnios and 165 post-term pregnancies with normal amniotic fluid index. The same method of induction was applied during labor to both groups: dinoproston and oxytocin. The delivery mode, rate and the indications of cesarean deliveries and neonatal outcomes were compared. Results: Cesarean section and vaginal delivery rates were similar in both groups. Also duration of first and second stage of vaginal delivery between two groups were similar. However, the rate of cesarean section performed due to fetal distress was found to be significantly higher in the study group when compared with the control group. Meconium stained amniotic fluid was statistically significant (p<0.001) in oligohydramnios group. Mean fetal birth weight in oligohydramnios and post-term groups was 3169 gr and 3335 gr, respectively. Conclusion: Although pregnancies with isolated oligohydramnios are not at high risk for cesarean delivery, the rate of cesarean section performed due to fetal distress is higher than when compared with post-term pregnancies.
