About this trial
This is a noninferiority randomized control trial of two cervical preparation methods prior to same-day Dilation \& Evacuation (D\&E). Cervical preparation is a process that softens and dilates the cervix prior to a procedure.
The primary objective is to evidence noninferiority of cervical preparation using a single-balloon catheter method when compared to a group receiving osmotic dilators, specifically in D\&E operative time.
Secondary objectives will compare the two methods for adequate dilation, ability to complete the operation in the same day, participant pain, satisfaction and safety.
