Conservative management of persistent postnatal urinary and faecal incontinence: randomised controlled trial

Abstract Objectives: To assess the effect of nurse assessment with reinforcement of pelvic floor muscle training exercises and bladder training compared with standard management among women with persistent incontinence three months postnatally. Design: Randomised controlled trial with nine months' follow up. Setting: Community intervention in three centres (Dunedin, New Zealand; Birmingham; Aberdeen). Participants: 747 women with urinary incontinence three months postnatally, allocated at random to intervention (371) or control (376) groups. Intervention: Assessment by nurses of urinary incontinence with conservative advice on pelvic floor exercises at five, seven, and nine months after delivery supplemented with bladder training if appropriate at seven and nine months. Main outcome measures: Primary: persistence and severity of urinary incontinence 12 months after delivery. Secondary: performance of pelvic floor exercises, change in coexisting faecal incontinence, wellbeing, anxiety, and depression. Results: Women in the intervention group had significantly less urinary incontinence: 167/279 (59.9%) v 169/245 (69.0%), difference 9.1% (95% confidence interval 1.0% to 17.3%, P=0.037) for any incontinence and 55/279 (19.7%) v 78/245 (31.8%), difference 12.1% (4.7% to 19.6%, P=0.002) for severe incontinence. Faecal incontinence was also less common: 12/273 (4.4%) v 25/237 (10.5%), difference 6.1% (1.6% to 10.8%, P=0.012). At 12 months women in the intervention group were more likely to be performing pelvic floor exercises (218/278 (79%) v 118/244 (48%), P<0.001). Conclusions: A third of women may have some urinary incontinence three months after childbirth. Conservative management provided by nurses seems to reduce the likelihood of urinary and coexisting faecal incontinence persisting 12 months postpartum. Further trials for faecal incontinence are needed. What is already known on this topic Vaginal delivery is a risk factor for urinary incontinence Three months after childbirth 20-30% of women still experience urinary incontinence Most women do not seek treatment What this study adds Women will use conservative treatments such as pelvic floor exercises or bladder training Conservative management prevents persistent urinary incontinence in about one in 10 women who have postnatal incontinence Coexisting persistent faecal incontinence is also improved
