Abstract
Objective: To assess the possibility of cervical elastography (compression elastography) use as a method for evaluating the effectiveness of pre-induction of labor in full-term pregnancy using a dilation catheter (double balloon and single-balloon Foley catheter).
Materials and methods: The study comprised 58 patients with singleton pregnancies at ≥37 weeks' gestation. Pre-induction was performed using two types of dilatation catheters. Cervical elastography and palpation using the Bishop score were performed before and after the procedure.
Results: The number of patients with an "absolutely soft" cervix according to the Bishop scale increased from 12% to 83% (p<0.001) after pre-induction of labor with a balloon catheter. According to elastography data of the anterior cervical lip, the proportion of "soft" and "very soft" cervix increased from 9% to 91% (p<0.001). We found high comparability of elastography data of the anterior cervical lip with the palpation data according to Bishop score (AUC=0.850). The relative risk of achieving optimal cervical maturity was 1.48 times higher when using a double balloon catheter, and the time to delivery was significantly shorter than when using a single balloon Foley catheter (p=0.033), without the increase in the incidence of complications.
Conclusion: Compression elastography is a new noninvasive tool for adequate assessment of the birth canal maturity, equal to the Bishop score. A double-balloon catheter is an effective and safe method for pre-induction of labor, ensuring faster achievement of cervical maturity.
