Introduction: A presumed association between more severe lower urinary tract symptoms (LUTS) and more severe functional constipation (FC) remains unconfirmed. Because the Rome IV criteria do not quantify FC, an adult constipation scoring system was modified and adapted for use in children., Objectives: The objective of this study was to assess the correlation between FC severity as determined by the modified constipation scoring system and LUTS severity in children/adolescents and the correlation between this modified scoring system and the Rome IV criteria., Study Design: This was a cross-sectional study including 5- to 17-year-old patients with LUTS, with or without FC. Patients with neurological and/or anatomical abnormalities of the genitourinary and/or gastrointestinal tract were excluded. Girls with Dysfunctional Voiding Symptom Score (DVSS) ≥6 and boys with DVSS ≥9 were diagnosed with lower urinary tract dysfunction (LUTD). Patients with at least two positive Rome IV criteria were considered constipated. The severity of FC according to the adapted constipation scoring system was classified as mild for scores of 1-10, moderate for scores 11-20, and severe for scores 21-30., Results: Of 128 patients with LUTS, 71 (55.5%) were female. Lower urinary tract dysfunction was detected in 107 patients (83.6%) and was more common in girls. Functional constipation was present in 80 patients (62.5%). Constipated children had higher constipation scores and DVSS, with both scores increasing with the severity of FC. Correlation was moderate between the constipation score and the DVSS (þ = 0.5, p < 0.001) and was strong between positivity for a greater number of Rome IV criteria and the constipation score (þ = 0.7, p < 0.001). Most of the constipated patients had mild or moderate FC, while in 30 non-constipated patients, the constipation score indicated mild FC., Discussion: Patients from a specialist center are more likely to have more severe medical problems, and this may have influenced the correlation between the scores. The modifications made to the constipation scoring system require a future validation study. Nevertheless, this study provides new data on urinary dysfunction and its association with FC and highlights the need to investigate occult bowel symptoms that could affect the treatment of urinary dysfunction., Conclusion: The intensity of FC as measured by the modified constipation scoring system correlated with the severity of the urinary symptoms in children/adolescents with LUTS/LUTD. In constipated patients, there was a correlation between the modified constipation scoring system and the Rome IV criteria. In non-constipated patients, the constipation scoring system identified symptoms/signs of bowel dysfunction not picked up by the Rome IV criteria. Finally, constipation score modified for use in children and adolescents could be important for research purpose and particularly having a prognostic importance., (Copyright © 2019.

Background: An association has been found between lower urinary tract dysfunction (LUTD) and emotional and behavioral problems, particularly in cases of urinary incontinence. Other associated symptoms and the coexistence of functional constipation require further investigation., Objective: To assess whether emotional and behavioral problems are more common in children and adolescents with LUTD., Study Design: A multicenter, cross-sectional, population-based study conducted in public places. Parents answered questions on urinary and psychological symptoms in their children aged 5-14 years. Children/adolescents with neurological problems or anatomical urinary tract abnormalities were excluded. The Dysfunctional Voiding Scoring System was used for assessing urinary symptoms, the Rome III Diagnostic Criteria for evaluating bowel symptoms, and the Strengths and Difficulties Questionnaire (SDQ) for evaluating emotional and behavioral problems., Results: Of the 806 children/adolescents included, 53% were female. The mean age was 9.1 ± 2.7 years. The prevalence of LUTD was 16.4%. Overall, 26.2% had abnormal scores in the overall SDQ scale, 29.2% in the emotional problems subscale, and 30% in the conduct problems subscale. Of the children with LUTD, 40.5% screened positive for emotional/behavioral problems, with a significant association being found for the overall SDQ scale (P < 0.001) and for the emotional problems (P < 0.001), conduct problems (P < 0.001), and hyperactivity (P = 0.037) subscales. Urinary urgency, urinary incontinence, and voiding postponement were significantly associated with a greater prevalence of abnormalities in the overall SDQ score (P = 0.05; P = 0.004, and P = 0.012, respectively). Bladder and bowel dysfunction was an aggravator of emotional and behavioral problems, with more intense symptoms, both in the overall SDQ scale and in the subscales. In the multivariate analysis, the factors independently associated with the presence of emotional and behavioral problems were LUTD (odds ratio [OR] = 1.91), constipation (OR = 1.7), studying in a government-funded school (OR = 2.2), and poor education of the head of the family (OR = 1.9)., Conclusions: Children and adolescents with LUTD have more emotional and behavioral problems, with bladder and bowel dysfunction being an aggravating factor for this association., (Copyright © 2018.
