Objectives: To describe the use of colonic washout enemas for persistent constipation in children treated for dysfunctional voiding by cognitive and biofeedback training.
Methods: We treated 50 children, who had dysfunctional voiding and persistent dilatation of the rectum notwithstanding adequate oral laxatives, with colonic washout enemas. We performed retrograde filling of the rectum with 20 mL/kg water, starting once daily for 2 weeks, then 3 times per week for 6 to 12 months.
