OBJECTIVES: To investigate the postnatal prevalence of sonographically diagnosed pelvic floor @entity130 , and the correlations with various antenatal/intrapartum predictors in primiparous @entity1 . METHODS: This was a prospective cohort study performed in a tertiary hospital with 9000 deliveries per annum. Of those invited, 202 (23.2%) primiparous @entity1 were assessed clinically at least 1   year after delivery by Pelvic Organ Prolapse Quantification ( @entity3577 -Q), two/three-dimensional transperineal sonography and quantification of serum collagen type III levels. RESULTS: There was a high prevalence of clinically significant @entity3577 ( @entity3577 ) on @entity3577 -Q staging: uterine prolapse, 63%; cystocele, 42%; and rectocele, 23%. Ballooning of the levator ani muscle (LAM) hiatus was detected in 33% and @entity121 in 29% of @entity1 , with partial @entity121 occurring in 15% and complete @entity155 in 14%. @entity3577 (odds ratios (ORs) given here for presence of multiple prolapse symptoms) were positively associated with similar prepregnancy symptoms (OR, 7.2 (95%   CI, 1.19-44.33)), @entity121 (OR, 4.8 (95%   CI, 1.99-11.34)) and forceps delivery (borderline significance; OR, 1.8 (95%   CI, 0.96-3.25)) and negatively associated with elective (OR, 0.2 (95%   CI, 0.09-0.63)) and emergency (OR, 0.3 (95%   CI, 0.12-0.83)) Cesarean section. LAM abnormality was associated with forceps delivery (OR, 4.9 (95%   CI, 1.44-16.97)) and prolapse (OR, 6.8-11.7 (95%   CI, 2.34-78.51)), whereas collagen levels did not play a role (OR, 1.001 (95%   CI, 0.99-1.02)). CONCLUSIONS: Clinically significant @entity3577 was common in relatively young premenopausal primiparous @entity1 . Partial or full levator @entity155 was seen in 29% of @entity1 and was associated with @entity3577 and related symptoms. Congenital factors seem to play little role in the etiology of @entity121 , and the main risk factor seems to be forceps delivery. Avoidance of difficult vaginal deliveries may prevent severe pelvic floor @entity130 . Copyright    2014 ISUOG. Published by John Wiley _ Sons Ltd.
