Intracervical double-balloon catheter versus dinoprostone for cervical ripening in labor induction in pregnancies with a high risk of uterine hyperstimulation.

Purpose: There are numerous methods for cervical ripening although not all of them are indicated in women presenting a higher risk of uterine hyperstimulation. To compare the efficacy and security of the two methods for cervical ripening in the induction of labor in these pregnancies.

Methods: Retrospective analysis of two cohorts consisting of pregnant women who gave birth from 2016 to 2019 (112 inductions with dinoprostone and 112 with intracervical double- balloon).

Analysis of measurement process of placental volume in early pregnancy: an interobserver reliability study.

Objective: To examine concordance among results obtained in measurement process of first-trimester placental volume using 3D ultrasound and eXtended Imaging Virtual Organ Computed-aided AnaLysis (XI-VOCAL®, 3DXITM, Medison, Seoul, Korea) image analysis by three different operators.

Methods: Twenty first-trimester normal pregnancy cases were selected for placental volume measuring using a Medison SA 8000 Live Prime® (Medison, Seoul, Korea) with a convex volumetric multifrequency abdominal probe. Images were processed and studied independently by three operators with different grade of training.
