Comparison of dynamic transperineal ultrasound and defecography for the evaluation of pelvic floor disorders

Introduction X-ray defecography is considered the gold standard for imaging pelvic floor pathology. However, it is limited by the capability to demonstrate only the posterior pelvic compartment, significant radiation exposure, and inconvenience. Dynamic transperineal ultrasound (DTP-US) can visualize all of three pelvic floor compartments, is free of radiation, and does not cause significant discomfort. The aim of this study was to evaluate the level of consistency between defecography (DEF) and DTP-US in the diagnosis of pelvic floor deformations.
