title: Induction of labor in women that had a previous cesarean delivery.
abstract: OBJECTIVE
  This study aims to evaluate factors that predict the likelihood of the success of induction of labor (IOL) in women that had a previous cesarean section (pCS).
  
  
  METHODS
  Pregnant women with one pCS performed more than 18 months prior were included in this retrospective observational study. Of the 242 eligible women, 234 were enrolled; 120 (51.3%) of these women delivered vaginally (VD), with the remainder receiving a repeat CS.
  
  
  RESULTS
  The main reasons for IOL were premature rupture of membranes (PROM) (37.1%) and post-date pregnancy (26.5%). Babies with a birth weight≥4000 g were more prevalent in women undergoing CS (21/114; 18.4%, p<0.02) and were associated with the failure of IOL. Uterine rupture during labor (1.3%) occurred in three cases. Having had a previous vaginal delivery (VD) (p=0.01), not being African (p=0.022), and receiving IOL for PROM (p=0.04) with a cervical Bishop score≥5 (p=0.015) significantly predicted the occurrence of a VD, with an 15% variance (p<0.001). An age>35 years appears to not affect the success of induction.
  
  
  CONCLUSIONS
  A successful IOL should be expected in Caucasian women induced for PROM with a favorable Bishop score.
