OBJECTIVE: We sought to assess the safety of transcervical Foley catheter (TCF) placement for cervical ripening in women undergoing induction of labor (IOL) after prior cesarean by evaluating the risk of uterine rupture.
STUDY DESIGN: We performed a secondary analysis of the Maternal-Fetal Medicine Unit's Cesarean Section Registry, a prospective observational cohort study. We included women with a history of ≤2 low-transverse cesarean deliveries who underwent IOL at ≥24 weeks of gestational age with a live singleton fetus without major anomalies. We excluded those who received prostaglandins or laminaria. We performed multinomial logistic regression to calculate adjusted odds ratios (aORs) for uterine rupture and dehiscence. Relevant confounders included prior vaginal delivery, pregnancy-induced hypertension, chorioamnionitis, and cervical effacement and dilation on admission.
RESULTS: A total of 2,564 women were eligible. Unadjusted analysis demonstrated no increased risk of uterine rupture with TCF (1.9 vs. 0.9%; p = 0.10) but an increased risk of uterine dehiscence (1.9 vs. 0.6%; p = 0.02). After adjustment, TCF was not associated with an increased risk of uterine rupture (aOR: 2.02; 95% confidence interval [CI]: 0.71-5.78) or uterine scar dehiscence (aOR: 1.32; 95% CI: 0.37-4.72).
CONCLUSION: Foley catheter is a safe tool for mechanical dilation in women undergoing IOL after prior cesarean.
