PREVALENCE OF FECAL INCONTINENCE AMONG WOMEN WITH URINARY-INCONTINENCE

Four hundred and sixty-five women attending a urodynamic clinic were i nterviewed, and completed a detailed bowel questionnaire, about their urinary and bowel symptoms. All the women underwent video-cystourethro graphy with pressure and flow studies. The reported incidence of faeca l incontinence was 15.3% (n = 71) on direct questioning and 26% (n = 1 21) on the postal questionnaire. Faecal incontinence was more common i n women with a urodynamic diagnosis of detrusor instability (30% (n = 26)) than among women diagnosed as having genuine stress incontinence (21% (n = 38)). Denervation and myogenic injuries sustained during chi ldbirth have been suggested as a common cause for genuine stress and f aecal incontinence, but there may be an alternative mechanism to expla in why women with detrusor instability suffer from faecal incontinence .
