Levator ani muscle avulsion is a frequent postpartum trauma imposing a considerable risk of pelvic organ prolapse on women in later life. Furthermore, the trauma reduces the effectiveness of pelvic reconstructive surgery and has a detrimental effect of the sexuality of the affected women. The trauma occurs most frequently in the first vaginal delivery with an incidence of 10-30%. However, the risk of levator avulsion in women after vaginal birth after caesarean section (VBAC) is unknown although possible increased risk has been suggested.~The aim of the study is to assess the prevalence of levator ani avulsion among women who delivered vaginally after a caesarean section and make a comparison with a primiparous cohort. The secondary aim is to evaluate and compare the health related quality of life regarding pelvic floor disorders and sexuality.
