Abstract:
The aim of this is to evaluate the diagnostic value of anal endosonography performed during pressing anterior wall of anal canal with a finger introduced into the lumen of vagina for the identification of anal sphincter defects. Anal ultrasound (AUS) with a finger introduced into the lumen of vagina was performed in a group of 55 women with anal sphincter defects recognized initially in standard AUS. This technique prevented false positive diagnoses of sphincter defects in 12 out of a group of 55 women (21.8%).
