Obstetric antecedents for postpartum pelvic floor dysfunction
The purpose of this study was to evaluate prospectively the association between selected obstetric antecedents and symptoms of pelvic floor dysfunction in primiparous women up to 7 months after childbirth.
All nulliparous women who were delivered between June 1, 2000, and August 31, 2002, were eligible for a postpartum interview regarding symptoms of persistent pelvic floor dysfunction. Responses from all women who completed a survey at or before their 6-month contraceptive follow-up visit were analyzed. Obstetric antecedents to stress, urge, and anal incontinence were identified, and attributable risks for each factor were calculated.
During the study period, 3887 of 10,643 primiparous women (37%) returned within 219 days of delivery. Symptoms of stress and urge urinary incontinence, were significantly reduced (P < .01) in women who underwent a cesarean delivery. Symptoms of urge urinary incontinence doubled in women who underwent a forceps delivery (P = .04). Symptoms of anal incontinence were increased in women who were delivered of an infant who weighed >4000 g (P = .006) and more than doubled in those women who received oxytocin and had an episiotomy performed (P = .01).
The likelihood of symptoms of pelvic floor dysfunction up to 7 months after delivery was greater in women who received oxytocin, who underwent a forceps delivery, who were delivered of an infant who weighed >4000 g, or who had an episiotomy performed. Women who underwent a cesarean delivery had fewer symptoms of urge and stress urinary incontinence.
