Effects of High-Intensity Focused Ultrasound (HIFU) Treatment on Fecal Continence and Anorretal Fisiology

"A suppository will be used to clean the rectum 3 to 4 hours prior to the examination. And the pressures of rest and voluntary contraction of the anal sphincter will be evaluated, as well as the behavior of the pubortal muscle during the evacuation maneuver. Retinal inhibitory reflex (RIRA), sensitivity and rectal capacity will also be evaluated.~Questionnaires that evaluate the pre and post HIFU anal physiology will also be applied at the time of manometry."
