We contacted 208 women 13 years after they suffered an obstetrical anal sphincter tear in order to estimate the effect of subsequent vaginal deliveries on anal continence. Among the 177 eligible responders, 129 sustained a partial or complete 3rd degree and 48 a 4th degree tear; 114 women had subsequent vaginal deliveries. Anal incontinence was more common in women with 4th (25.0%) than with 3rd degree tears (11.5%, p = 0.049). Subsequent vaginal deliveries were associated with a higher prevalence of severe incontinence in women with 4th degree tears (p = 0.023). No aggravation or increase in prevalence of incontinence was observed in women with 3rd degree tears. These results suggest that in a subsequent pregnancy, careful evaluation is necessary and an abdominal delivery may be advisable for women with previous major sphincter trauma.

Anal incontinence after childbirth is associated with defects of the anal sphincter diagnosed by endosonography. Subsequent deliveries increase the risk of incontinence, particularly among women with a sphincter defect diagnosed after the first delivery.

Urinary incontinence is a frequent affliction in women and may be disabling and costly {LE1}. When consulting for urinary incontinence, it is recommended that circumstances, frequency and severity of leaks be specified {Grade B}. The cough test is recommended prior to surgery {Grade C}. Urodynamic investigations are not needed before lower urinary tract rehabilitation {Grade B}. A complete urodynamic investigation is recommended prior to surgery for urinary incontinence {Grade C}. In cases of pure stress urinary incontinence, urodynamic investigations are not essential prior to surgery provided the clinical assessment is fully comprehensive (standardised questionnaire, cough test, bladder diary, post-void residual volume) with concordant results {PC}. It is recommended to start treatment for stress incontinence with pelvic floor muscle training {Grade C}. Bladder training is recommended at first intention in cases with overactive bladder syndrome {Grade C}. For overweight patients, loss of weight improves stress incontinence {LE1}. For surgery, sub-urethral tape (retropubic or transobturator route) is the first-line recommended technique {Grade B}. Sub-urethral tape surgery involves intraoperative risks, postoperative risks and a risk of failure which must be the subject of prior information {Grade A}. Elective caesarean section and systematic episiotomy are not recommended methods of prevention for urinary incontinence {Grade B}. Pelvic floor muscle training is the treatment of first intention for pre- and postnatal urinary incontinence {Grade A}. Prior to any treatment for an elderly woman, it is recommended to screen for urinary infection using a test strip, ask for a bladder diary and measure post-void residual volume {Grade C}. It is recommended to carry out a cough test and look for occult incontinence prior to surgery for pelvic organ prolapse {Grade C}. It is recommended to carry out urodynamic investigations prior to pelvic organ prolapse surgery when there are urinary symptoms or occult urinary incontinence {Grade C}.

Cervical evaluation by vaginal sonography, fetal fibronectin and interleukin-6 are the best methods for predicting preterm birth.
