Improvement in Bladder Function in Children With Functional Constipation After a Bowel Management Program

Abstract

Purpose We sought to determine if children with functional constipation (FC) would have an improvement in bladder function with treatment of constipation with a bowel management program (BMP). Methods A single-institution review was performed in children aged 3-18 with FC who underwent a BMP from 2014-2020. Clinical characteristics, bowel management details, and the Vancouver Symptom Score for Dysfunctional Elimination Syndrome (VSS), Baylor Continence Scale (BCS), and Cleveland Clinic Constipation Score (CCCS) were collected. Data were analyzed using linear mixed effect modeling with random intercept.Results 241 patients were included with a median age of 9 years. Most were White (81%) and 47% were female. Univariate tests showed improvement in VSS (-3.6, P<0.0001), BCS (-11.96, P<0.0001), and CCCS (-1.9, P<0.0001) among patients having undergone one BMP. Improvement was noted in VSS and CCCS among those with more than one BMP (VSS: -1.66, P=0.023; CCCS: -2.69, P<0.0001). Multivariate tests indicated undergoing a BMP does result in significant improvement in VSS, BCS, and CCCS (P<0.0001).Conclusions There is significant improvement in bladder function in children with FC who undergo a BMP. For patients with bowel and bladder dysfunction and FC, a BMP is a reasonable treatment strategy for lower urinary tract symptoms.
