Role of Transabdominal Ultrasonography in the Evaluation of Pediatric Patients With Daytime Wetting: A Single-Center Pilot Study.

OBJECTIVES: Urinary incontinence (UI) is a frequent cause of admission to pediatric nephrology outpatient clinics. The aim of this study was to determine whether anatomical changes in lower urinary tract structures (retrovesical angulation [RVA] and bladder neck position [BNP]) are associated with UI in pediatric patients with daytime-wetting in comparison to healthy children. METHODS: In this prospective study, patients with daytime UI diagnosed using the Dysfunctional Voiding Symptom Score of the International Children's Continence Society and 3-day-voiding/bowel diary were compared with an age- and sex-matched control group without incontinence. In addition to routine clinical evaluation, RVA and BNP were measured at rest using transabdominal ultrasound (TA-US). Intra-rater agreement was estimated. RESULTS: A total of 88 children were included in the study, with 44 children (22 boys, 22 girls) each in patient and control groups. RVA was significantly greater and BNP was significantly lower in the patient group versus control group (RVA: 134.30 ± 10.05 vs 127.94 ± 13.15, P = .013; BNP: 11.88 ± 4.53 vs 17.20 ± 5.55, P < .001, respectively). Irrespective of the presence of incontinence, girls had a significantly greater RVA than boys (P < .001). However, there was no difference between sexes in BNP values (P = .630). Intra-rater agreement was very strong for RVA (P < .001, r = .897), and strong for BNP (P < .001, r = .774). CONCLUSIONS: TA-US imaging is a non-invasive and practical procedure routinely performed in pediatric patients presenting with UI complaints. Our study demonstrated anatomical changes in lower urinary tract structures in pediatric patients with UI. These changes should be considered in the diagnosis, follow-up, and treatment of patients with UI.

Transcutaneous electrical nerve stimulation as add-on therapy in children receiving anticholinergics and/or mirabegron for refractory daytime urinary incontinence: A retrospective cohort study.

AIMS: To investigate if children with daytime urinary incontinence (DUI) and overactive bladder (OAB) refractory to standard urotherapy and medicinal treatment, would experience improvement in symptoms after add-on treatment with transcutaneous electrical nerve stimulation (TENS). METHODS: Children were retrospectively enrolled from tertiary referral centers at Aarhus and Aalborg University Hospitals. All data were retrieved from the patients' journals. All children were prescribed TENS as an add-on treatment to the highest-tolerable dose of medicinal treatment in a standardized regime of 2 h a day for around 3 months. Primary endpoints were the number of wet days per week (WDPW) and incontinence episodes per day. Effect of treatment was defined as greater or equal to 50% reduction in the frequency of DUI episodes. Secondary endpoints were to establish predictive factors for the effect of treatment using logistic regression. RESULTS: Seventy-six children diagnosed with DUI and OAB refractory to treatment with standard urotherapy and pharmacological treatment, at the age of 5-16 years were included from February 2017 to February 2020. A reduction in WDPW (from 6.31 [5.86-6.61] to 4.27 [3.45-4.90], p < 0.05) and incontinence episodes per day (from 2.45 [1.98-2.91] to 1.43 [1.07-1.80], p < 0.05) was observed. Twelve patients became completely dry. At 6 months follow-up, seven of the 12 complete responders had relapsed while five remained dry. A history of constipation before TENS was a predictor of poor treatment response (p = 0.016). CONCLUSIONS: TENS as add-on to anticholinergic treatment seems effective in a number of children with treatment-refractory DUI.

Anxiety disorders, depression and incontinence in preschool children-A population-based study.

OBJECTIVE: The aim was to examine associations of specific anxiety disorders, depressive symptoms, and incontinence in a representative, population-based sample of preschool children. METHODS: All preschool children of a defined geographical area examined before school-entry were included. Parents completed a questionnaire including the Preschool Feelings Checklist (PFC), eight questions referring to nocturnal enuresis (NE), daytime urinary incontinence (DUI), fecal incontinence (FI) and constipation, and 30 items regarding Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) diagnostic criteria of separation anxiety disorder (SAD), social phobia (SOC), specific phobia (PHOB), and generalized anxiety disorder (GAD). Data of 1206 children (mean age = 5.7 years; 53.5% boys) are presented. RESULTS: 34.6% of incontinent children had an anxiety disorder based on DSM-5 criteria and 13.3% had clinically relevant depressive symptoms (measured by the PFC). Rates of incontinence overall were 14.1% (11.9% NE, 3.1% DUI, and 1.8% FI) and 6.3% for constipation. Rates of SOC and PHOB were increased in NE (20.8% and 25.4%), DUI (39.3% and 34.5%) and FI (35.3% and 50.0%) compared to continent children (13.5% and 17.2%). Children with constipation had higher rates of SOC, PHOB, and GAD than those without. Compared to continent children (9.7%), depressive symptoms were more frequent in children with NE (26.8%), DUI (50.0%), and FI (61.9%). CONCLUSION: Anxiety disorders and depressive symptoms are common in children with incontinence. The most specific DSM-5 disorders associated with incontinence are SOC and PHOB, which can be incapacitating and may require treatment. Due to the high rates of anxiety disorders, it is important to screen all children with incontinence, for example, with specific questionnaires.

Incontinence and sleep disturbances in young children: A population-based study.

AIMS: Nocturnal enuresis (NE), daytime urinary incontinence (DUI), fecal incontinence (FI), as well as sleep and behavioral problems are common in young children. The aim of this study was to analyze the association of sleep and psychological parameters for all types of incontinence in a representative sample of young children. METHODS: Six hundred thirty eight (of 1161) children with a mean age of 5.9 years (50.9% boys) were assessed during their mandatory school entry examination. The participation rate was 55%. Instruments included the Strengths and Difficulties Questionnaire, the Children's Sleep Habits Questionnaire and other clinical questions. Incontinence was diagnosed according to ICCS standards. Constipation was assessed by two questions. RESULTS: 17.1% of children had at least one type of incontinence, 14.8% had NE, 5.0% DUI, 2.1% FI, and 4.8% were constipated. 6.7% of children had clinically relevant psychological problems. 22.7% of children had sleep problems regularly (5-7 times/week). A wide variety of sleep problems were reported. Children with incontinence were not affected by a higher rate of sleep problems. Children with NE had fewer night wakings and those with constipation fewer parasomnias. Sleep and psychological problems were significantly associated, especially in children with DUI and FI. CONCLUSIONS: Sleep and behavioral problems are common in young children. Psychological problems have a clear impact on sleep. Young children with incontinence do not have more sleep problems than continent children. Therefore, both sleep and psychological problems should be addressed in young children with incontinence.

Behavioral comorbidity, overweight, and obesity in children with incontinence: An analysis of 1638 cases.

AIMS: Children with nocturnal enuresis (NE), daytime urinary incontinence (DUI), and fecal incontinence (FI) are at risk for behavioral problems, overweight, and obesity. The aim of this study was to analyze the specific behavioral and weight comorbidity in subtypes of incontinence. METHODS: A total of 1638 consecutive patients presented to a tertiary incontinence clinic from 2012 to 2018 was examined prospectively according to ICCS criteria. Behavioral symptoms were measured with the Child Behavior Checklist (CBCL). Psychiatric disorders were diagnosed according to ICD-10 criteria. Weight categories were calculated according to WHO recommendations. RESULTS: The mean age was 7.8 years, 67% of patients were male. Fifty-seven percent had NE (n = 934), 33% DUI (n = 547), and 40% FI (n = 656). Boys had significantly higher rates of NE and FI than girls. Of all children, 39.2% (n = 539) had a clinically relevant CBCL total score. A total of 28.3% (n = 463) had an ICD-10 psychiatric diagnosis, mainly ODD and ADHD, and 28.6% (n = 463) were overweight or obese. Boys were more often affected by behavioral symptoms, psychiatric disorders, and overweight/obesity. Children with NE had the highest rate of overweight/obesity. Except for primary nonmonosymptomatic NE, subtypes of incontinence did not differ regarding behavioral symptoms and weight categories. However, overweight/obesity was significantly associated with behavioral and psychiatric parameters. CONCLUSIONS: Behavioral symptoms and psychiatric disorders, as well as overweight/obesity are important risk factors associated with incontinence, but the interaction between these factors is complex. In clinical settings, all children with incontinence should be screened with behavioral questionnaires. Also, weight should be measured, and overweight/obesity should be addressed.

Incontinence and headache in preschool children.

AIMS: Headaches in preschool children are associated with behavioral and gastrointestinal symptoms. As the co-occurrence with incontinence is not known in young children, the aim of the study was to examine associations of headache, psychological symptoms and nocturnal enuresis (NE), daytime urinary incontinence (DUI), and fecal incontinence (FI) in a population-based sample of preschool children. METHODS: All preschool children of a defined geographical area were examined at school-entry. Parents completed a 22-item questionnaire, including 14 headache, 4 incontinence, and 25 items of the Strength and Difficulties Questionnaire (SDQ). Five hundred eighty-five children (50.4% males) with a mean age of 5.8 years were included. RESULTS: In total, 27.2% of all children had headaches. 15.7% had secondary and 11.3% primary headaches. Five children had migraine and five tension-type headaches, while all others were unclassifiable. 9.4% of children had incontinence (7.7% NE; 2.4% DUI, 1.2% FI) and 4.0% constipation. The rates of incontinence did not differ between children with primary and those without headache for NE (12.9% vs 7.5%), DUI (3.1% vs 2.7%) or FI (3.0% vs 1.0%), but for constipation (12.1% vs 2.6%). Incontinent children had significantly more behavioral and externalizing symptoms, children with headache more internalizing problems. Primary headache was a significant predictor for internalizing, while constipation and FI were predictors for externalizing symptoms. CONCLUSIONS: This population-based study showed that headache is associated with constipation, but not with incontinence in preschool children. Headache and incontinence are common risk factors for specific psychological symptoms and should be assessed in clinical practice.

Urinary and bowel disfunction in autism spectrum disorder: a prospective, observational study.

BACKGROUND: Vesico- sphincter and bowel dysfunction have been frequently detected in Autism spectrum disorder (ASD) patients, but to date no consistent information exist on adults affected by the disease. We evaluated the prevalence and types of bladder and bowel disfunction (BBD) in young and adult patients affected by ASD. SUBJECTS AND METHODS: Twenty- seven adults and 20 children/teens with ASD and a matched group of typically developing subjects were enrolled. Daily pads use and episodes of urinary incontinence (UI) were recorded in a 3- day voiding diary. Patients underwent also the measurement of post-void urinary residual volume and 3- day bowel diary. In addition, type and duration of the pharmacological agents assumed by the patients were accurately recorded. RESULTS: Any type of UI was observed in 85.1% of adults and in 90% of children/teens. In adults, nocturnal enuresis (NE, 62.9%) and diurnal intermittent UI (37%) were the most frequently observed bladder dysfunction while in children/ teens were NE (75%) and diurnal continuous UI (40%). In all patients was demonstrated a significant relationship between urinary symptoms and pharmacological agents, particularly NE and clotiapine (p<0.004) and periciazine (p<0.008). CONCLUSIONS: Young and adult patients with ASD present with a high prevalence of BBD and concomitant antipsychotic medications could to play a contribution in induction and/or maintaining of BBD.

Incontinence in persons with Down Syndrome.

AIMS: To assess the rates of incontinence and associated psychological problems in children, adolescents and adults with Down Syndrome, a genetic syndrome caused by partial or complete triplication (trisomy) of chromosome 21 and characterized by typical facial features, a physical growth delay and mild or moderate intellectual disability. METHODS: Three hundred and seventeen persons with Down Syndrome (4-51 years) were recruited through a German parent support group (59.6% male, mean age 19.2 years). The Parental Questionnaire: Enuresis/Urinary Incontinence, the Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms, as well as the Developmental Behavior Checklist (DBC) for parents or for adults were filled out by parents or care-givers. RESULTS: 17.2% of the sample had nocturnal enuresis, 15.9% had daytime urinary incontinence, and 14.2% had fecal incontinence. Incontinence was present in 64.0% of young children (4-12 years), 10.3% of teens (13-17 years), 12.8% of young adults (18-30 years) and in 22.4% of older adults (>30 years). 13.6% of children and 8.4% of adults had a DBC score in the clinical range. 19.5% of children and 27.8% of adults with incontinence had behavioral problems. There was a significant association between nocturnal enuresis, daytime urinary incontinence and clinical DBC scores in adults. CONCLUSIONS: Incontinence in Down Syndrome is mainly present in young children and increases in older adults. Behavioral comorbidity is associated with incontinence only in adults with Down Syndrome. Screening and treatment of incontinence in individuals with Down Syndrome is recommended.

Incontinence and psychological problems in children: a common central nervous pathway?

Nocturnal enuresis is caused by a mismatch between the nocturnal bladder capacity and the nocturnal diuresis rate, in the presence of a deficient arousability in the majority of patients, according to the pediatric and urologic literature. Psychiatric and psychologic literature are still concentrating on the potential role of psychological factors and central nervous mechanisms in the pathogenesis, as is reflected in the DMS-5 criteria. However, research has clearly shown several important comorbidities between neuropsychological dysfunctions and nocturnal enuresis. Due to the increased comorbidity of (neuro)psychological problems, sleep problems, circadian rhythms, and enuresis, the question arises as to whether there is a possible common central pathway in the pathogenesis. It is likely that the coexistence of these problems can be attributed to a common central nervous system involvement. The specific role of the central nervous system remains unclear, but several pathways are possible. The high comorbidity between enuresis, sleep, and (neuro)psychological functioning is probably attributable to a common pathogenetic pathway, emphasizing the importance of a multidisciplinary focus in screening and treatment in children with nocturnal enuresis.

Incontinence and parent-reported oppositional defiant disorder symptoms in young children--a population-based study.

BACKGROUND: Oppositional defiant disorder (ODD) and incontinence are common disorders of childhood. We have examined associations between ODD symptoms and incontinence in a representative sample of young children. METHODS: A questionnaire with seven questions referring to incontinence, eight DSM-IV items of ODD, 15 items of the Home Situations Questionnaire and six items regarding eating, drinking or toileting refusal was administered to the parents of 718 children at school-entry from a defined geographical area at school-entry. RESULTS: Of the 718 6-year-old children included in the analysis, 8.2% had nocturnal enuresis (NE), 1.5% had daytime urinary incontinence (DUI) and 1.1% had faecal incontinence (FI). Significantly more boys than girls had NE (12 vs. 4.3%). Overall, 6.7% of children had ODD symptoms. Rates of ODD symptoms were significantly higher in incontinent children (19.5%) than in continent children (5.2%), with the highest rate of ODD symptoms in children with DUI (36.4%). Children with incontinence (mean 6.1 episodes) or ODD symptoms (mean 8.4 episodes) showed non-compliant behaviours in more problem situations than continent children (mean 4.5 episodes) or children without ODD symptoms (mean 4.5 episodes). CONCLUSIONS: Incontinence and ODD are common comorbid disorders at school-entry age. Boys are more affected by both disorders. Children with DUI have the highest rate of ODD symptoms. As ODD symptoms affect many daily family situations, ODD needs to be diagnosed and treated in children with incontinence, as it can negatively affect compliance.
