Anal sphincter residual defects on single translabial TUI slices are weakly associated with measures of anal incontinence. Single-slice defect angle is too poor a predictor to allow validation of the 30° defect angle cut-off used in endoanal ultrasound. Larger studies in populations with a higher prevalence of anal incontinence are needed before we can disregard anal sphincter defects smaller than 30° on translabial ultrasound.
