Blair Bell as early as 1931 estimated that each year in England and Wales, at least 60,000 women, that is 10 percent, of all mothers, were more or less crippled as the result of childbirth. Other the past thirty years the concept and management of childbirth has altered significantly, the majority of mothers recover to full health following childbirth. But in some women vaginal birth can result in impaired function of the muscle of the pelvic floor because of sphincter disruption, pudendal nerve damage or loss of integrity and healthiness of supporting connective tissue (Allen et al., 1990). Mason et al. (1999) studied the prevalence of stress urinary incontinence during pregnancy and following delivery, they came to the conclusion that post-partum stress urinary incontinence has a prevalence rate of 31%, in this study an association was linked between parity and stress incontinence.
