Predicting cesarean delivery for failure to progress as an outcome of labor induction in term singleton pregnancy.

Background: Induction of labor is one of the most common interventions in modern obstetrics, and its frequency is expected to continue to increase. There is inconsistency as to how failed induction of labor is defined; however, the majority of studies define success as the achievement of vaginal delivery. Induction of labor in nulliparous women poses an additional challenge with a 15% to 20% incidence of failure, ending in emergency operative deliveries.

The value of three-dimensional ultrasound in identifying Mullerian anomalies at risk of adverse pregnancy outcomes.

Objective: To examine the reliability of three-dimensional ultrasound (3 D-US) in the differentiation between subseptate and arcuate uteri, due to the different associated pregnancy outcomes; refine the existing 3 D-US parameters and evaluate the concordance between 3 D-US and MRI in diagnosing these anomalies.

Study Design: This was a prospective cohort study of 455 women suspected of having a Mullerian anomaly. The diagnosis of subseptate, bicornuate or arcuate uterus was made by 3 D-US in 55 women.

Three-dimensional sonohysterography compared with vaginoscopic hysteroscopy for evaluation of the uterine cavity in patients with recurrent implantation failure in in vitro fertilization cycles.

Study Objective: To estimate the degree of agreement between 3-dimensional sonohysterography (3D-SHG) and vaginoscopic hysteroscopy (VH) in detection of uterine cavity abnormalities in patients with recurrent implantation failure in in vitro fertilization cycles.

Design: Comparative observational cross-sectional study (Canadian Task Force classification II-1).

Setting: Private assisted-conception unit.
