There was inclusion of patients with Hirschsprung disease (HD), anorectal malformation (ARM) and functional constipation (FC). Patients with other congenital or neurological conditions were excluded. Control group consisted of inpatients and outpatients without abdominal complaints. FC was diagnosed according to ROM-IV-criteria. For HD and ARM, we followed a list of symptoms. To assess fecal load, we visualized the TRD using the Klijn (Klijn et al. in J Urol 172:1986\u20131988, 2004) method. The bladder was moderately full. The fecal load was assessed retrograde from the rectum. Follow-up was at 1\/3\/6\u00a0months. Secondary data were collected from medical records. Sample size calculated a priori and follow-up group with new gathered data.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p><jats:italic>p<\/jats:italic> value for TRD in all groups significant with <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05 and in grouped follow-up.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Ultrasound is a useful tool for assessing fecal load and helps diagnose constipation and monitor BM.
