[From delivery mode to incontinence].
Vaginal delivery has been considered to be the main cause of pelvic static disorders since obstetric is taught. Epidemiological studies generally confirm the greater prevalence of urinary or fecal incontinence after delivery. Analysis of available data lead to the following observations. Urge urinary incontinence is not associated with the number of pregnancies or the mode of delivery. At age equivalence, stress urinary incontinence is more frequent among women who delivered by C-section compared with women without children. Also at age equivalence, stress incontinence is more frequent in women who delivered by the vaginal route compared with those who had C-section. This difference disappears with age, while stress urinary incontinence during pregnancy is a risk factor 15 days later. The only published randomized trial demonstrated a higher prevalence of stress urinary incontinence three months after delivery in the vaginal route group, but this difference disappeared at two years. Fecal incontinence is more frequent after delivery, especially in the event of forceps delivery. Nevertheless late after delivery, the prevalence of fecal incontinence is similar between spontaneous vaginal, forceps, or C-section delivery. The mode of delivery thus has an impact on continence. However, late after delivery, the influence of pregnancy and delivery fades out either due to a process of repair or via the intermediary of other predominant risk factors (age, tissue quality). The beneficial effect of programmed C-section on continence has not been demonstrated.
