Colonic washout enemas for persistent constipation in children with recurrent urinary tract infections based on dysfunctional voiding

To describe the use of colonic washout enemas for persistent constipation in children treated for dysfunctional voiding by cognitive and biofeedback training. 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. During the 6-month follow-up, 30 children were free from urinary tract infections. In 20 children we observed partial relief of complaints. On ultrasound all children showed a normalized diameter of the rectum. In 33 patients washout treatment could be stopped with continuing success. Relapse of a distended rectum triggered the need for chronic intermittent enema therapy in 17 patients. A few patients reported pain during enema treatment; otherwise, we noted no counter-effect. Dysfunctional voiding combined with constipation in children can be cured by washout enemas if oral laxatives fail
