INTRODUCTION AND HYPOTHESIS: Pregnancy and childbirth predispose to pelvic floor dysfunction (PFD), coinciding with functional and anatomical changes in the pelvic floor. To some extent, these can be assessed by transperineal ultrasound (TPUS), yet the correlation between ultrasound findings and symptoms has not been well elucidated. We hypothesised that pregnant women with PFD would show different findings at TPUS. METHODS: This is a planned secondary analysis of a prospective cohort study. Pregnant women were asked to fill out standardised questionnaires on PFD and undergo TPUS at 12-14 weeks and 28-32 weeks of gestation. We compared bladder neck descent, urethral rotation, retrovesical angle, pelvic organ descent, genital hiatus dimensions and the presence of anal sphincter defects between women with and those without PFD using t test and Fisher's exact test. Linear mixed-effects models were used to assess the correlation between TPUS findings and PFD severity. As this is a secondary subgroup analysis of participants who underwent TPUS, no sample size was determined upfront. RESULTS: At Valsalva, women with urinary incontinence had more pronounced bladder neck descent (p = 0.02) and urethral rotation (p < 0.01), as well as wider retrovesical angles (p = 0.04) and larger genital hiatus areas (p < 0.01). After controlling for age, BMI and parity, the retrovesical angle was the only persistent predictor of urinary incontinence. No correlation was observed between any TPUS marker and symptoms of either prolapse or anorectal dysfunction. CONCLUSIONS: In pregnant women, symptoms of urinary incontinence, but not of prolapse and anorectal dysfunction, are associated with differences in pelvic floor anatomy at TPUS.
