Does sacral nerve stimulation improve global pelvic function in women?

Abstract

Many women undergoing sacral neuromodulation for faecal incontinence have coexisting pelvic floor dysfunction. We used a global pelvic-floor assessment questionnaire to evaluate the effect of sacral neuromodulation on non-bowel related symptomatology. The electronic Personnel Assessment Questionnaire - Pelvic Floor (ePAQ-PF) is a validated Web-based electronic pelvic floor questionnaire. Women with faecal incontinence underwent assessment using the ePAQ. Pre- and poststimulator data were analysed over a 4.5-year period. Forty-three women (mean age 56.5years; median follow up 6.8months) were included. All (100%) had urinary symptoms, 81.4% had vaginal symptoms and 85.7% described some sexual dysfunction. There was a significant improvement in faecal incontinence and in bowel-related quality of life (P<0.005) as well as in irritable bowel syndrome (IBS)-related symptoms (P<0.01) and in bowel-related sexual heath (P< 0.01). Symptoms of vaginal prolapse significantly improved (P=0.05). There was also improvement in symptoms of overactive bladder (P=0.005) and in urinary-related quality of life (P<0.05). A global health improvement was reported in 58.1%, mainly in bowel evacuation (P<0.01) and in vaginal pain and sensation (P<0.05). In sexually active female patients, significant improvements in vaginal and bowel-related sexual health were seen (P<0.005). Improvement in general sex life following stimulation was reported in 53.3%. A Web-based electronic pelvic-floor assessment questionnaire has demonstrated global improvement in pelvic floor function in bowel, urinary, vaginal and sexual dimensions in women following sacral neuromodulation for faecal incontinence.
