Pelvic floor dysfunction after vaginal and cesarean delivery among singleton primiparas

Area of Science:

• Obstetrics and Gynecology
• Pelvic Floor Disorders
• Women's Health Research

Background:

• Pelvic floor dysfunction (PFD) encompasses conditions like pelvic organ prolapse (POP), urinary incontinence (UI), and fecal incontinence (FI).
• Understanding the long-term impact of delivery mode on PFD is crucial for maternal healthcare.
• Primiparous women represent a key demographic for studying initial PFD development.

Purpose of the Study:

• To compare the incidence of POP, UI, and FI symptoms in women following vaginal versus cesarean delivery.
• To assess the long-term (5-10 years postpartum) prevalence of PFD symptoms.
• To determine the relative risk of PFD symptoms based on delivery mode.

Main Methods:

• A prospective cohort study involving singleton primiparous women at a Czech university hospital.
• Women were enrolled between 2002-2007 and surveyed 5-10 years postpartum using internet-based validated questionnaires.
• Statistical analysis included calculation of relative risk (RR) for POP, UI, and FI symptoms.

Main Results:

• Data from 641 vaginal and 224 cesarean deliveries were analyzed.
• Urinary incontinence (UI) scores were significantly higher in the vaginal delivery group (P=0.005).
• No significant differences were found in pelvic organ prolapse (POP) or fecal incontinence (FI) scores between groups.

Conclusions:

• Vaginal delivery is associated with a significantly higher occurrence of urinary incontinence (UI) symptoms compared to cesarean delivery.
• No significant differences in pelvic organ prolapse (POP) or fecal incontinence (FI) were observed between the two delivery methods.
• These findings highlight UI as a key PFD symptom influenced by delivery mode.
