Dynamic transperineal ultrasound in the workup of men with obstructed defecation: a pilot study.

Background: Dynamic transperineal ultrasound has been used in women for the noninvasive investigation of functional disorders of the posterior pelvic floor, but its use in men has been limited by technical difficulties related to the consistency of the male perineum.

Objectives: The aim of this study was to explore the efficacy of dynamic transperineal ultrasound in diagnosing posterior pelvic floor dysfunction in men.

Design: This is a study of diagnostic accuracy.
