Importance: Pregnancy and childbirth are risk factors for developing pelvic floor disorders (PFDs), and this continues postpartum ("fourth trimester"). Knowledge of PFDs among women of childbearing age is lacking and presents an opportunity for education.

Objectives: The aim of this study was to compare the increase in knowledge of PFDs in patients who received written handouts versus interactive workshops as measured by the Prolapse and Incontinence Knowledge Questionnaire (PIKQ).

Introduction And Hypothesis: The objectives were to determine whether a difference exists in the duration of pelvic floor disorder (PFD) symptoms among patients presenting to urogynecologists in two healthcare systems: private and county; and to elucidate differences in baseline characteristics, type of PFDs, symptom severity and management, stratified by healthcare plans.

Methods: A multi-center retrospective study was conducted including new patients presenting to three urogynecology clinics between March 2016 and May 2018: one private clinic (site A) and two public clinics in the same county healthcare system (sites B and C). Baseline data included age, race, BMI, parity, and comorbidities.

Introduction And Hypothesis: Uterosacral ligament suspension surgery is commonly utilized to correct post-hysterectomy vaginal vault prolapse (VVP). Vaginal intraperitoneal uterosacral vault suspension (IUSVS) is a viable option, but intraperitoneal access can be challenging. An alternative approach is an extraperitoneal uterosacral vault suspension (EUSVS).
