Psychosocial Difficulties in Children Referred to Pediatric Urology: A Closer Look

Learning from the past: How lessons from Hinman syndrome can inform the psychological management of lower urinary tract dysfunction

INTRODUCTION

Pediatric patients with lower urinary tract dysfunction (LUTD) experience a variety of medical and psychosocial concerns that can negatively impact their clinical management and quality of life. When initially described by Drs Hinman and Baumann, patients with a form of severe LUTD, later dubbed Hinman syndrome, were characterized as having a "general attitude of being failures." While this mention was noteworthy as it incorporated an understanding of the interplay between psychological factors and urologic conditions, there have been delays in implementing psychological intervention as a standard of care in patients with LUTD broadly, and perhaps too keen of a focus on youth diagnosed with Hinman syndrome specifically.

METHODS

A non-systematic reviewed of LUTD related to psychological management was performed. Clinical recommendations were developed by a multicenter and multidisciplinary team of care providers with topic expertise.

OBJECTIVE

The aim of this paper is to propose a systems thinking paradigm for how to involve psychology, or psychological principles, across the spectrum of patients with LUTD with the hope of improving attention to specific aspects of care that may improve clinical management.

DISCUSSION

Children across the spectrum of LUTD are likely to benefit from psychological interventions and would benefit from such involvement early on to mitigate the impact of psychosocial concerns on medical outcomes. Pediatric psychologists are well-suited to identify and provide individualized care to patients in greatest need of intervention, such as through pre-procedural preparedness, addressing non-adherence, and with the use of evidence-based, targeted mental health interventions. Psychologists are also apt at implementing interventions while taking into consideration the severity of LUTD, in the context of the patient's psychological, developmental, cultural, familial, and social determinants of health considerations. Youth with severe forms of LUTD, such as Hinman syndrome, likely exemplify the challenges of LUTD that benefit from multidisciplinary intervention.

CONCLUSION

Medical and psychological collaboration are key to ensuring symptom mitigation and emotional support for patients across the entire spectrum of LUTD.

Comorbidity of Obsessive-Compulsive Symptomatology and Bowel and Bladder Dysfunction in a Tertiary Children's Hospital: A Case Series

OBJECTIVE

To improve understanding of co-occurring obsessive-compulsive disorder (OCD) and bowel and bladder dysfunction (BBD) in an outpatient pediatric urology clinic setting. To provide a series of clinical care recommendations to enhance the identification and integrated medical and behavioral health treatment of these disorders.

METHODS

Authors participated in a series of discussions to define the patient population and specific aims for the study. Efforts were made to select index patients of diverse background despite limited sample availability. Three patients were ultimately selected for the study.

RESULTS

The case studies highlight the connection between urinary issues and underlying OCD symptoms. All patients were initially seen for medical treatment of urological symptoms, then referred for psychological evaluation, and were diagnosed with and received treatment for OCD. Similarities among the cases, including experience of phantom urinary incontinence, stressors present that contributed to symptoms, and obsessive fears of incontinence that led to compulsive behavior, were discussed. Differences between the cases, including patient age, sex, and compulsive behavior demonstrated (ie, urinary frequency, excessive wiping) were also reviewed.

CONCLUSION

Access to a behavioral health provider can enhance the identification of comorbid psychological disorders and can reduce duration of symptoms through appropriate psychological treatment. Authors provide recommendations for screening measures and reinforce importance of including basic education on psychiatric diagnoses and impact on urological symptoms in urology and pediatric fellowship training programs. Future research exploring prevalence of comorbid psychiatric conditions and efficacy of treatment interventions in a pediatric urology population would be beneficial.

Pediatric Psychology in a Urology Division: Unifying Complex Medical and Mental Health Treatment

PURPOSE OF REVIEW

Although pediatric psychology is heavily involved in many medical divisions, its involvement in a urology division is still relatively new and its role continuously evolving and growing.

RECENT FINDINGS

This article reviews the limited research on the use of psychology in a urology division, including psychosocial struggles across urology diagnoses, dysfunctional voiding, and anxiety surrounding medical procedures and surgery. Urinary diagnoses and presenting problems seen by pediatric psychologists and medical providers at an urban children's hospital are also included. Based on the complex conditions and varied presenting concerns in a urology division, potential assessments and future research are suggested to help gather data for this population moving forward and expand the literature on urology psychology.

Overactivity index: A noninvasive and objective outcome measure in overactive bladder in children

INTRODUCTION

Reports showed that observing detrusor overactivity (DO) and maximum cystometric capacity (MCC) may guide rational pharmacotherapy. Since urodynamic studies (UDS) are challenging for both patients and the healthcare system, a non-invasive objective prognostic marker is preferable.

OBJECTIVES

To investigate the value of the overactivity index (OI), a non-invasive measure calculated from the frequency-volume chart (FVC), for predicting the presence of symptoms and abnormal UDS in children with non-neurogenic OAB.

STUDY DESIGN

This was a prospective interventional study on a consecutive sample of 92 children with urgency treated with anticholinergics and standard urotherapy. Data from history, physical examination, bladder diaries, kidneys and bladder ultrasonography, uroflow, urinalysis, urine culture, and UDS was collected at baseline, and after 3 and 6 months. Binary logistic regression was used to evaluate noninvasive parameters as predictors of Overactive Bladder Symptom Score (OABSS) total score >2 and DO and/or small MCC defined as <65% of expected bladder capacity (EBC) for age. OI was calculated as (1 - (median (all voided volumes in FVC in ml))/(0.65 ∗ EBC in ml)) ∗ 100.

RESULTS

At baseline, 26 patients (36.1%) had DO and small MCC, while 21 patients (29.2%) only had DO. In 18 patients (25.0%) only small MCC was found. Seven patients had normal findings and 20 did not perform a urodynamic study. OI ≥ 23 returned as a single significant predictor of OABSS >2 (OR 7.97, 95% 1.97-32.22, p = 0.004) in multivariate regression (R² = 30.8%; AUC = 0.86). OI correlated with "urgency episodes over two weeks" and MCC/EBC with medium (r = 0.45) and large effect (r = -0.56), respectively, p = 0.001.

DISCUSSION

A strong correlation of OI and MCC/EBC ratio is useful, as rise in MCC is predictive of a positive outcome. Also, calculating the OI is more practical than performing UDS. This could contribute to the use of OI as a predictive marker for starting (or continuing) anticholinergic treatment (when OI ≥ 23) or for maintaining urotherapy alone (when OI < 23) in children with OAB. The limitations were lack of external validation of OI, a 37-49% drop-off rate for follow-up visits at 3 and 6 months, respectively, and not performing UDS on all participants at every follow-up visit.

CONCLUSIONS

OI was found to be a significant predictor of the presence of OAB symptoms and correlated with the number of urgency episodes. It could estimate how much MCC differs from EBC.

Systematic review and meta-analysis: relationships between attention-deficit/hyperactivity disorder and urinary symptoms in children

Lower urinary tract symptoms (LUTS), e.g., urinary frequency, pressure, urgency, and overactive bladder syndrome, are commonly reported in children with attention-deficit/hyperactivity disorder (ADHD). Understanding the co-occurrence of these conditions has implications regarding clinical approaches, treatments, and improved quality of life. We conducted a systematic review and meta-analysis to examine the relationships between LUTS and ADHD in children. We searched for articles published between January 1990 and July 2019, in PubMed, CENTRAL, and PsycNet. Two authors independently screened all articles and extracted data. We performed random-effect meta-analyses for ADHD with pooled outcomes for LUTS. We identified 119 relevant articles in the literature and 18 articles fulfilled the inclusion criteria for the systematic review, of which, 5 articles had sufficient data for meta-analysis. Examining ADHD among individuals with LUTS, the odds ratio was 2.99 (95% CI 1.13, 7.88, p < 0.001), compared to controls. In multiple studies, the mean overall score for LUTS, using a standardized measure, was significantly higher in patients with ADHD in comparison to controls, and the severity of ADHD was positively associated with the severity of LUTS. Younger age in children was correlated with a higher LUTS score. Different subtypes of urinary incontinence demonstrated differences in behavioral problems and psychiatric comorbidity. Sex differences in LUTS were not consistent across articles. Our results indicate clinically significant associations between ADHD and LUTS in children. Because LUTS and ADHD are common disorders in children, clinicians should be aware of these associations as they inform optimal assessment and treatment strategies.

The Importance of Understanding Parental Perception When Treating Primary Nocturnal Enuresis: A Topic Review and an Institutional Experience

Primary nocturnal enuresis (PNE) is a common childhood disorder that adversely affects a child’s mental well-being and social life. Our clinical experience showed parents and their child often have significantly different perspective of enuresis, and these differences can affect family dynamics, treatment approaches, and treatment success. Parents’ perception of PNE also influences the likelihood of seeking medical treatment, and we found parents of children with enuresis have markedly different beliefs regarding bedwetting than those of physicians. Because achieving remission for PNE requires parents and their child to actively participate in treatment, assessing their expectancy of success and their beliefs will allow clinicians to adjust treatment goals as necessary. When treating PNE, guidelines consistently recommend incorporating bed alarms as part of the therapy. However, through interviewing parents and treating their children, we found parents preferred medications or other behavioral strategies, such as limiting water intake, because of their convenience. Many parents would complain bed alarms woke them up instead of their child, and they would soon give up on bed alarms. Part of assessing their beliefs includes assessing their confidence in their child being able to wake up to alarms and to persist with treatment. Understanding how they manage and approach setbacks will also determine the treatment modality suited for their child. In this review paper, we detailed our experiences interviewing parents and treating their child with NE with urodynamics and medications at the Changhua Christian Hospital in Taiwan.

Systematic review and meta-analysis identify significant relationships between clinical anxiety and lower urinary tract symptoms

BACKGROUND

Lower urinary tract symptoms (LUTS), such as voiding symptoms, overactive bladder, and interstitial cystitis, and anxiety disorders are often comorbid conditions in patients. However, the existing evidence regarding the rates and nature of the co-occurrence of these conditions has not been systematically evaluated. The aim of this study was to examine these relationships.

METHODS

We conducted a systematic review and meta-analysis to examine the relationship between LUTS and anxiety. We searched for articles published from January 1990 to July 2019 in PubMed, CENTRAL, PsycINFO, and Google Scholar. Outcomes were anxiety-related disorders and symptoms (clinically significant anxiety) and LUTS. We performed random-effects meta-analyses, inspected funnel plots, and applied the Egger's test to evaluate publication bias. We followed PRISMA guidelines and recorded our protocol on PROSPERO (ID = CRD42019118607).

RESULTS

We identified 814 articles, of which 94 fulfilled inclusion criteria, and 23 had sufficient data for meta-analysis. The odds ratio (OR) for clinically significant anxiety among individuals with LUTS was 2.87 (95% CI: 2.38,3.46, p < .001). The OR for LUTS among individuals with clinically significant anxiety was 2.87 (95% CI: 1.07,7.74, p < .001), although very few studies examined this relationship. A large value of I² index suggests high heterogeneity between studies.

CONCLUSION

The results demonstrate a significant association between clinically significant anxiety and LUTS in both females and males. There were limited studies on younger individuals and on individuals ascertained for clinically significant anxiety, which should motivate further study in these areas. Understanding the co-occurrence of these conditions will lead to better prevention and interventions to ameliorate the progression of the symptoms and improve the quality of life. A thorough assessment of anxiety may provide more optimal care for LUTS patients.

Treatment of obstructive sleep apnea does not treat primary nocturnal enuresis

INTRODUCTION

Primary Nocturnal Enuresis (PNE), obesity, and obstructive sleep apnea (OSA) are suggested to share a complex interaction whereby risk for PNE is increased when obesity and airway obstruction are present. We aimed to evaluate whether surgical or medical management of OSA in the treatment of patients with PNE and improves PNE outcomes.

STUDY DESIGN

Our institutions electronic medical record was queried for patients who underwent a pediatric diagnostic polysomnogram (PDPSG) for the complaint of PNE between October 2010 and September 2020 and were diagnosed with OSA. Retrospective chart review was performed of the 59 patients identified. Patients were divided based on therapy type for their OSA. Groups included those no therapy, any therapy which includes patients undergoing tonsillectomy and adenoidectomy (T&A) and/or continuous positive airway pressure (CPAP) and those who chose T&A. Primary outcome was to evaluate effects of treating OSA with T&A and effects on PNE outcome based on International Children's Continence Society (ICCS) definitions of complete, partial or no improvement. Separate grouping based on ICCS PNE outcome were also made for evaluation of variables associated with each group. Secondary outcome evaluated role of BMI in success of treatments of PNE. Chi-squared and one-way ANOVA tests were performed.

RESULTS

59 patients (64.4% male, mean age at diagnosis 8.8 years old) underwent a PDPSG for PNE. Monosymptomatic PNE was diagnosed in 40.7% while 32.2% had non-monosymptomatic PNE and the remainder were unknown. Patients were predominantly Caucasian (47.5%), with an average BMI of 20.6 kg/m² 25 patients underwent no therapy for their OSA while the remaining 34 received treatment. No statistically significant difference between those receiving and those forgoing therapy were noted in age, race, gender, BMI, type of PNE or Apnea-Hypopnea Index. There was also so significant difference in ICCS defined enuresis outcomes (p = 0.871) with over 60% in both groups experiencing resolution or improvement. Follow up was significantly different between cohorts, measured at 43 months for those receiving therapy for OSA and 29.1 months for those forgoing therapy. When considering only those who chose T&A as their therapy for PNE, there were once again, no significant differences between groups including ICCS enuresis outcome. Sub-grouping based on ICCS enuresis outcome revealed no associations between variables measured and improvement of PNE (p > 0.05), other than defining type of PNE (p = 0.012).

CONCLUSION

In patients with OSA and PNE, surgical treatment of airway obstruction had no effect on resolution of PNE.

Transient receptor potential channels in sensory mechanisms of the lower urinary tract

Disruptions to sensory pathways in the lower urinary tract commonly occur and can give rise to lower urinary tract symptoms (LUTS). The unmet clinical need for treatment of LUTS has stimulated research into the molecular mechanisms that underlie neuronal control of the bladder and transient receptor potential (TRP) channels have emerged as key regulators of the sensory processes that regulate bladder function. TRP channels function as molecular sensors in urothelial cells and afferent nerve fibres and can be considered the origin of bladder sensations. TRP channels in the lower urinary tract contribute to the generation of normal and abnormal bladder sensations through a variety of mechanisms, and have demonstrated potential as targets for the treatment of LUTS in functional disorders of the lower urinary tract.

Emotional and behavioral problems in children and adolescents with lower urinary tract dysfunction: a population-based study

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.

Development of a Standardized Approach for the Assessment of Bowel and Bladder Dysfunction

INTRODUCTION

Bowel and bladder dysfunction (BBD) is a common pediatric condition that describes a constellation of lower urinary tract symptoms (LUTS) associated with constipation. Many children with BBD have comorbid neuropsychiatric and psychosocial concerns that are not routinely assessed. The aim of quality improvement (QI) was to establish a comprehensive assessment for BBD by developing and evaluating (1) a standardized clinician assessment form and (2) parent-reported questionnaire.

METHODS

From July 2017 to April 2018, a prospective QI study was conducted in the BBD network. A standardized assessment form was developed based on literature review and expert opinions, with targeted sections for LUTS, constipation, and psychosocial history. Before clinic, families of children referred for BBD were given a questionnaire to clarify voiding, stooling, and dietary patterns. Physicians utilized the assessment form for new referrals. Afterward, both physicians and parents evaluated the assessment process anonymously.

RESULTS

A total of 15 physicians and 45 parents responded, with 67% of patients being between 4 and 10 years old and 51% male. Physicians responded that the assessment form reminded them to ask about specific LUTS (93%), constipation (87%), and psychosocial history (87%). Parents responded positively by agreeing that they felt included in care decisions (96%) and had questions answered appropriately (100%). Only 47% found the previsit package easy to complete.

CONCLUSIONS

In pediatric BBD consultations, a standardized assessment form can guide clinicians to efficiently gather a comprehensive history and screen for psychosocial risk factors. It can empower more pediatricians to evaluate BBD in the future.

Imipramine for refractory daytime incontinence in the pediatric population

INTRODUCTION AND OBJECTIVE

Lower urinary tract (LUT) and voiding dysfunction constitute a large percentage of pediatric urology referrals. Children with urinary incontinence unresponsive to behavioral modifications and traditional pharmacotherapy including anticholinergics and alpha blockers remain a challenge. We evaluated the impact of imipramine on treatment outcomes in children with refractory incontinence.

STUDY DESIGN

Children ≤18 years of age with refractory non-neurogenic daytime incontinence prescribed imipramine were identified. Patient demographics and baseline testing were assessed, as well as medication dosing and side effects of all patients. The Vancouver Symptom Score (VSS) was completed at the initial consultation and each subsequent clinic visit. The questionnaire was self-administered and completed by patients and/or parents. Treatment success was defined as per the International Children's Continence Society (ICCS).

RESULTS

One hundred and three patients (55 males and 48 females) met the inclusion criteria. The intention-to-treat response rate was 65% (complete 44, partial response 23). Sixteen (15.6%) patients were non-responders and 20 (19.4%) were lost to follow-up. There was no statistical difference between all groups with regards to age, baseline VSS, and dose. Of those children with complete follow-up (n = 83), 44 (53%) experienced complete treatment response. Pre- and post-VSS were statistically different in both complete and partial response groups (complete 19.5-9.5; p < 0.0001; partial 19.7-13; p = 0.0002) (Table). Side effects were reported by 11 out of 83 (13.3%) patients; partial responders experienced a higher likelihood of side effects (26.1%; p = 0.03).

DISCUSSION

The mainstay of LUT dysfunction management in children is implementation of a bowel program and timed voiding regimen, with additional treatment modalities and pharmacotherapy added depending upon prevailing symptomatology. Daytime incontinence refractory urotherapy, anticholinergics, and/or non-selective alpha blockers can be difficult to treat, and can be unresponsive to parasacral transcutaneous electrical nerve stimulation (TENS) and percutaneous tibial nerve stimulation (PTNS). We observed that over half of children with refractory daytime incontinence reported complete resolution of daytime accidents with imipramine. Limitations of the study include the retrospective nature, relatively small sample size and lack of control group.

CONCLUSIONS

Two-thirds of children with refractory daytime incontinence experienced treatment response to imipramine, adding a valuable tool to the pediatric urologist's armamentarium in managing select, challenging patients.

Children with nocturnal enuresis and attention deficit hyperactivity disorder: A separate entity?

INTRODUCTION

There is ongoing debate about whether nocturnal enuresis (NE) is affected by the presence of attention deficit hyperactivity disorder (ADHD) in children. Clarifying this relationship could categorize them as a separate entity, potentially requiring a different management from enuretic children without ADHD.

AIMS

To study whether (1) children with ADHD exhibited greater severity of enuresis and associated voiding symptoms compared with children without ADHD, (2) whether there was a difference in enuretic response to treatment between children with/without ADHD, (3) whether previously prescribed medication for ADHD affected severity of enuresis or voiding symptoms, and response to treatment.

METHODS

Data on all consecutive children seen with primary NE and ADHD and age- and gender-matched children with NE without ADHD over the course of 2 years were extracted from our database. Controls were identified using a random number generator to choose patients within each age/gender group. Changes in Dysfunctional Voiding Scoring System (DVSS) and Bristol scores were assessed before and after treatment for NE using repeated measures ANOVAs. Number of weekly wet nights was compared between the groups before and after the treatment of enuresis. Children with more than a 50% decrease in number of wet nights per week were categorized as responding to treatment.

RESULTS

Compared with controls, ADHD children (N = 95) had significantly more severe voiding symptoms, NE and constipation (Table). No significant differences were found between children on ADHD medication (63.2%) and those who were not on ADHD medication (36.8%) on any of the demographic and pre-treatment clinical parameters. Similar enuretic response rates to behavioral modification alone were seen in both study (13.5%) and control (12.8%) groups (p = 0.73). Response to pharmacological treatment was seen in nine patients with ADHD (42.9%) and in six (20.7%) controls, with pharmacological intervention being significantly more effective than behavioral modification for patients with ADHD (p = 0.012). Additionally, no difference was found between ADHD patients on and off ADHD medication in terms of response to enuresis treatment.

CONCLUSION

In children with primary NE, the presence of ADHD was associated with more severe NE, voiding symptoms and constipation. The severity of voiding symptoms and/or NE was unrelated to the use of stimulant medication. The response to behavioral modification was comparable in both groups. However, patients with ADHD were significantly more responsive to medication for NE compared with behavioral modification, indicating a possible benefit for earlier pharmacological treatment for enuresis in this population subgroup.

Role of body mass index in school-aged children with lower urinary tract dysfunction: Does weight classification predict treatment outcome?

INTRODUCTION

Lower urinary tract (LUT) dysfunction comprises a large percentage of pediatric urology referrals. Childhood obesity is a major health concern, and has been associated with voiding symptoms. We assessed the impact of body mass index (BMI) on treatment outcomes of children presenting with LUT or bladder-bowel dysfunction (BBD).

STUDY DESIGN

Children aged 5-17 years diagnosed with non-neurogenic LUT dysfunction and no prior urologic diagnoses were identified. Patient demographics including BMI, lower urinary tract symptoms, constipation, medical and psychologic comorbidities, imaging, and treatment outcomes were evaluated. BMI was normalized by age and gender according to percentiles: underweight < 5th, healthy 5th to <85th, overweight 85th to <95th, and obese > 95th percentile. Uni- and multivariate analyses were performed to identify predictors of treatment response.

RESULTS

During an 18-month period, 100 children (54 girls, 46 boys) met the inclusion criteria. The mean age at diagnosis was 7.7 ± 2.4 years, and mean length of follow-up 15.3 ± 13.1 months. Sixty-nine patients were a normal weight, 22 were overweight, and nine were obese. Fifteen percent of the children had complete treatment response, 63% partial response, and 22% non-response. On univariate analysis, children with elevated BMI (p = 0.04) or history of urinary tract infection (p = 0.01) were statistically more likely to not respond to treatment. Controlling for all other variables, children with BMI > 85th percentile had 3.1 times (95% CI 1.11-8.64; p = 0.03) increased odds of treatment failure (Table).

DISCUSSION

BBD management includes implementation of a bowel program and timed voiding regimen, with additional treatment modalities tailored on the basis of the prevailing symptoms. We observed that school-aged children with a BMI ≥ 85th percentile were over three times more likely to experience treatment failure when controlling for all other patient characteristics including constipation and a history of urinary tract infection. Limitations of the study include the relatively small sample size, lack of uroflow with electromyography to confirm the presence or the absence of detrusor sphincter dyssynergia, and inconsistent anticholinergic dosing.

CONCLUSIONS

Nearly one-third of school-aged children presenting to our institution with LUT or BBD were overweight or obese when normalized for age and gender. Children with LUT dysfunction and elevated BMI are significantly less likely to experience treatment response.

Evidence-Based Psychosocial Treatments for Pediatric Elimination Disorders

Pediatric elimination disorders are common in childhood, yet psychosocial correlates are generally unclear. Given the physiological concomitants of both enuresis and encopresis, and the fact that many children with elimination disorders are initially brought to their primary care physician for treatment, medical evaluation and management are crucial and may serve as the first-line treatment approach. Scientific investigation on psychological and behavioral interventions has progressed over the past couple of decades, resulting in the identification of effective treatments for enuresis and encopresis. However, the body of literature has inherent challenges, particularly given the multicomponent nature of many of the treatment packages. This review identified 25 intervention studies-18 for nocturnal enuresis and 7 for encopresis-over the past 15 years and classified them according to the guidelines set forth by the Task Force on the Promotion and Dissemination of Psychological Procedures. For nocturnal enuresis, the urine alarm and dry-bed training were identified as well-established treatments, Full Spectrum Home Therapy was probably efficacious, lifting was possibly efficacious, and hypnotherapy and retention control training were classified as treatments of questionable efficacy. For encopresis, only two probably efficacious treatments were identified: biofeedback and enhanced toilet training (ETT). Best practice recommendations and suggestions for future research are provided to address existing limitations, including heterogeneity and the multicomponent nature of many of the interventions for pediatric elimination disorders.

Medical Comorbidity of Attention-Deficit/Hyperactivity Disorder in US Adolescents

Understanding patterns of medical comorbidity in attention-deficit/hyperactivity disorder (ADHD) may lead to better treatment of affected individuals as well as aid in etiologic study of disease. This article provides the first systematic evaluation on the medical comorbidity of ADHD in a nationally representative sample (National Comorbidity Replication Survey-Adolescent Supplement; N = 6483) using formal diagnostic criteria. Survey-weighted odds ratios adjusted for demographics, additional medical, and mental disorders were calculated for associations between ADHD and medical conditions. Models adjusted for demographics revealed significantly increased odds of allergy, asthma, enuresis, headache/migraine, and serious stomach or bowel problems. After adjusting for comorbidity, across the medical conditions, enuresis and serious stomach problems were the strongest correlates of ADHD. These findings confirm the pervasive medical comorbidity of ADHD reported in previous clinical and community-based studies. The intriguing salience of enuresis and serious stomach or bowel conditions may also provide an important clue to multisystem involvement in ADHD.

Simultaneous urodynamic and anorectal manometry studies in children: insights into the relationship between the lower gastrointestinal and lower urinary tracts

BACKGROUND

Children with urinary incontinence (UI) have associated functional constipation (FC) and fecal incontinence (FI). The physiology between lower urinary tract (LUT) and anorectum in children has not been elucidated.

AIMS

Observe the effect of rectal distention (RD) on LUT function, and bladder filling and voiding on anorectal function.

METHODS

Children with voiding dysfunction referred to Boston Children's Hospital were prospectively enrolled in combined urodynamic (UDS) and anorectal manometry (ARM). Anorectal and urodynamic parameters were simultaneously measured. Patients underwent two micturition cycles, first with rectal balloon deflated and second with it inflated (RD). Lower urinary tract and anorectal parameters were compared between cycles.

KEY RESULTS

Ten children (seven UI, four recurrent UTIs, nine FC ± FI) were enrolled. Postvoid residual (PVR) increased (p = 0.02) with RD. No differences were observed in percent of bladder filling to expected bladder capacity, sensation, and bladder compliance with and without RD. Bladder and abdominal pressures increased at voiding with RD (p < 0.05). Intra-anal pressures decreased at voiding (p < 0.05), at 25% (p = 0.03) and 50% (p = 0.06) of total volume of bladder filling.

CONCLUSIONS & INFERENCES

The PVR volume increased with RD. Stool in the rectum does not alter filling cystometric capacity but decreases the bladder's ability to empty predisposing patients with fecal retention to UI and UTIs. Bladder and abdominal pressures increased during voiding, demonstrating a physiological correlate of voiding dysfunction. Intra-anal pressures decreased during bladder filling and voiding. This is the first time intra-anal relaxation during bladder filling and voiding has been described.

The Relationship Between Child Anxiety Related Disorders and Primary Nocturnal Enuresis

BACKGROUND

Nocturnal enuresis, often called bedwetting or sleep wetting, is a common problem in children after the age of five and may lead to symptoms such as infection, incontinence and frequent urination. This problem refers to a state in which children after the age of five have no control of their urine for six continuous months and it cannot be attributed to any organic factors or drug use.

OBJECTIVES

In this study we aimed to study generalized anxiety disorder as one of the possible causes of primary nocturnal enuresis.

MATERIALS AND METHODS

In this case-control study 180 children with primary nocturnal enuresis and same number of healthy children with a mean age of 7 - 17 years old with the same demographic characteristics were selected. The study took place at Amir Kabir hospital of Arak, Iran during year 2014. After collecting the information, diagnosis was verified based on the diagnostic and statistical manual of mental disorders (DSM) IV-TR criteria. Results were analyzed using the SPSS software (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, version 20.0. Armonk, NY: IBM Corp.).

RESULTS

Frequency of generalized anxiety disorder, panic disorder, school phobia, social anxiety, separation anxiety, history of anxiety in mother, history of primary nocturnal enuresis in parent's family and body mass index had a significant difference between the two groups (P = 0.005).

CONCLUSIONS

With the results obtained from this study we could say that there was a clear significant difference between the two control and patient groups for all subgroups of anxiety disorders such as generalized anxiety disorder and their relationship with primary nocturnal enuresis. Given the higher prevalence of generalized anxiety disorder, panic disorder, school phobia, social anxiety, separation anxiety and comparison with healthy children, it is recommended for all children with primary nocturnal enuresis to be investigated and treated for generalized anxiety disorder.

Non-biological determinants of paediatric bladder bowel dysfunction: A pilot study

OBJECTIVES

Children with bladder and bowel dysfunction (BBD) constitute a significant proportion of referrals at paediatric urology clinics worldwide, presenting with a wide range of symptom severity that may significantly affect quality of life. Non-biological factors may play a key role in triggering BBD severity, but these underpinning causes of BBD during childhood are still unknown. The aim of this study was to identify the effects of personal, family related and environmental variables on the severity of BBD symptoms in school-aged children.

STUDY DESIGN

A pilot, prospective, observational study was conducted on 53 children diagnosed with BBD, and their legal guardian(s), on their first referred visit to a paediatric BBD clinic led by nurse practitioners. Upon receiving consent, patients and their legal guardian(s) completed three study questionnaires, with the guidance of research coordinators. The first questionnaire was the Dysfunctional Voiding Scoring System (DVSS); the second, a three-part questionnaire used to collect demographic information and data on the patient, their family and environmental characteristics; and the third gathered a detailed history of the child's lifestyle regimen, focusing on their bowel and bladder function.

RESULTS

Most of the children were female (66%), with an average age of 8.35 years. Most children attended public schools (74%) and none reported failing a grade. The mean parental age was 41.4 years (SD = 4.9 years), 62% of the families had two children and 53% were Caucasian. The mean DVSS score for this sample was 9.9 (SD = 4.2, range 2-21). Daycare attendance, school problems and unplanned pregnancy showed statistically significant influences on the severity of BBD and were associated with higher DVSS scores according to the Table below.

CONCLUSIONS

Children with BBD attending urology outpatient clinics as new referrals had more severe symptoms when they were born from an unplanned pregnancy, attended daycare and/or had school problems. These findings suggest that interventions aimed at decreasing BBD severity, or preventing its onset in school-aged children, should focus on the environment surrounding them, specifically on the interaction between personal, familial and environmental factors. These factors seem to have an important effect on paediatric continence, as children grow and develop under numerous societal influences and social interactions.

Parents have different perceptions of bed-wetting than children from six to 15 years of age

AIM

Enuresis is a common childhood disorder that negatively affects children's social and psychological well-being. This study investigated the psychological and emotional problems of children in Taiwan who wet the bed between the ages of six and 15 by comparing feedback from the children, their parents and a control group.

METHODS

This case study featured 93 children with primary nocturnal enuresis from enuresis clinics, and their parents, and 98 nonenuretic controls and parents from the local community. All the parents completed the Behavioural and Emotional Rating Scale (BERS) and all the children completed the Teenage Self-Concept Scale (TSCS). T-scores were used for statistical comparisons and high scores related to higher self-concept.

RESULTS

The parents and their children displayed different perceptions of enuresis, with more behavioural and emotional problems in enuretic children. Older children and children with more severe enuresis reported more difficulties, and low maternal education was also a risk factor.

CONCLUSION

Parental attitudes and perceptions towards bed-wetting were different from their children's. The children's age, enuresis severity and their mothers' educational level were potential risk factors that affected well-being. Health practitioners need to facilitate communication between enuretic children and their parents in addition to monitoring their psychological well-being.

Adenotonsillectomy improves quality of life in children with sleep-disordered breathing regardless of nocturnal enuresis outcome

BACKGROUND

Nocturnal enuresis (NE) and sleep-disordered breathing (SDB) have both been associated with impaired health-related quality of life (HRQoL). The following were investigated: (1) whether tonsillectomy and/or adenoidectomy (T&A) significantly affect the HRQoL in children with NE and SDB, and 2) differences in HRQoL between children with NE persistence versus resolution post-T&A.

METHODS

This was a prospective study comparing the HRQoL of children with SDB and NE (study group) pre- and 4 weeks post-T&A, and the HRQoL of children with SDB without NE (control group) (independent t-tests). HRQol was assessed using the Obstructive Sleep Apnea Quality of Life 18 questionnaire (OSAS-18), a validated measure containing five subscales that combine to create a total score. Individual items were scored on a Likert-type scale ranging from 1 (none of the time) to 7 (all of the time). Symptoms of SDB were evaluated using the validated Pediatric Sleep Questionnaire (PSQ). Mixed ANOVA was conducted to evaluate changes in the measures between the wet and dry children post-T&A. Pre- and post-T&A change scores were calculated for both the PSQ and the OSAS-18.

RESULTS

There were 30 children in the study group (18 male, mean age 9.07 years, SD 2.19), and 30 age-matched controls (16 male). There were no statistically significant differences between the two groups in regards to OSAS-18 total, PSQ total, BMI, diagnosis of snoring or OSAS on sleep study, or race. Overall, OSAS-18 and PSQ scores significantly improved in all children post-surgery (p < 0.001; p < 0.001, respectively), with no significant differences between dry and wet children post-T&A. The correlation between the pre- and post-T&A change scores on the OSAS-18 and PSQ was significant (r(29) = 0.58, p = 0.001), suggesting that a reduction in SDB symptoms post T&A is related to improved HRQoL.

CONCLUSIONS

T&A significantly improved HRQoL in all children with SDB and NE, regardless of NE outcomes. These findings support recommendations for T&A in children with SDB with or without NE.

Social stress in mice induces urinary bladder overactivity and increases TRPV1 channel-dependent afferent nerve activity

Social stress has been implicated as a cause of urinary bladder hypertrophy and dysfunction in humans. Using a murine model of social stress, we and others have shown that social stress leads to bladder overactivity. Here, we show that social stress leads to bladder overactivity, increased bladder compliance, and increased afferent nerve activity. In the social stress paradigm, 6-wk-old male C57BL/6 mice were exposed for a total of 2 wk, via barrier cage, to a C57BL/6 retired breeder aggressor mouse. We performed conscious cystometry with and without intravesical infusion of the TRPV1 inhibitor capsazepine, and measured pressure-volume relationships and afferent nerve activity during bladder filling using an ex vivo bladder model. Stress leads to a decrease in intermicturition interval and void volume in vivo, which was restored by capsazepine. Ex vivo studies demonstrated that at low pressures, bladder compliance and afferent activity were elevated in stressed bladders compared with unstressed bladders. Capsazepine did not significantly change afferent activity in unstressed mice, but significantly decreased afferent activity at all pressures in stressed bladders. Immunohistochemistry revealed that TRPV1 colocalizes with CGRP to stain nerve fibers in unstressed bladders. Colocalization significantly increased along the same nerve fibers in the stressed bladders. Our results support the concept that social stress induces TRPV1-dependent afferent nerve activity, ultimately leading to the development of overactive bladder symptoms.

Factor analysis of the pediatric symptom checklist in a population of children with voiding dysfunction and/or nocturnal enuresis

The research objective was to identify the factor structure of the pediatric symptom checklist (PSC) in children with voiding dysfunction and/or nocturnal enuresis who were seen in a pediatric urology clinic. Retrospective chart reviews were conducted for 498 consecutive patients, ages 6-16, who were seen over a 13-month period. The PSC, a 35-item measure used to screen for psychosocial difficulties, was completed by the patient's caregiver. Confirmatory factor analyses using three previous models were conducted. A four factor model comprised of internalizing, externalizing, attention problems, and chronic illness factors represented the best fit to the data. Within this population, the PSC appears to capture internalizing and externalizing problems, difficulties with attention, and possible side effects of a medical condition. This information could aid clinicians in assessing adjustment difficulties within this population and concurrently allow researchers to examine whether these specific factors are related to other relevant outcomes.

Phantom urinary incontinence in children with bladder-bowel dysfunction

OBJECTIVE

To report a previously undescribed condition in which children present with the sensation of wetness because of presumed urinary incontinence when they are actually completely dry. We have termed this entity "phantom" urinary incontinence (PUI).

MATERIALS AND METHODS

Twenty children referred to our pediatric urology clinic were diagnosed with PUI between 2009 and 2013. Patient demographics, associated bladder and bowel symptoms, concomitant diagnoses, imaging, management, and treatment outcomes were evaluated.

RESULTS

Twenty children (18 females and 2 males) were diagnosed with PUI over a 5-year interval. Mean age at diagnosis was 6.9 ± 2.5 years (range, 4-12 years). Nineteen patients (95%) had concomitant lower urinary tract symptoms, and all were also diagnosed with constipation. Urgency (75%) and frequency (50%) were the most common associated bladder symptoms. Of the 18 girls, 13 (72%) had associated vaginitis. Fourteen children (70%) carried a parent-reported diagnosis of obsessive-compulsive disorder or obsessive-compulsive disorder personality traits. Patients were managed with timed voiding, dietary modifications, and a bowel regimen. Ninety percent children experienced improvement of bladder-bowel dysfunction and resolution of PUI at a mean follow-up of 14.4 months.

CONCLUSION

Children with PUI have a high incidence of obsessive-compulsive traits. Phantom incontinence as well as associated lower urinary tract symptoms resolve with adherence to a strict bladder-bowel regimen.

Voiding dysfunction related to adverse childhood experiences and neuropsychiatric disorders

OBJECTIVE

Research has demonstrated the effect of adverse childhood experiences (ACEs) on later physiologic function and illness development. In the urologic literature, the relationship between bladder dysfunction and neuropsychiatric disorders is well documented. Observations in pediatric urology clinical practice suggest that a blend of these two areas of research can inform care of patients with voiding dysfunction.

METHODS

Retrospective review of 216 patients seen in a single pediatric urology clinic by a single provider over a 24-month period. A descriptive, correlational study design was used to assess the extent to which ACEs and neuropsychiatric disorders affected resolution of symptoms when patients were treated with a bowel and bladder retraining program. Patients were selected using diagnostic codes related to voiding dysfunction and a retrospective chart review was conducted.

RESULTS

A majority of patients who were seen for voiding dysfunction (60%) had at least one psychosocial factor. There is a greater prevalence of ACEs (51%) than neuropsychiatric disorders (25%). Children with either ACEs or neuropsychiatric disorders dropped out of treatment at a higher rate than those with neither. When factors were looked at separately, neuropsychiatric disorders were more likely to impede treatment progress than ACEs.

CONCLUSIONS

ACEs and neuropsychiatric disorders affect patients' ability to make progress with bowel and bladder retraining and to stay in treatment. Efforts specifically aimed at maintaining therapeutic relationships with patients who have ACEs are needed to fully treat this group, which typically has a high drop-out rate but high rate of resolution if they are able to stay involved in treatment.

Long-term use of solifenacin in pediatric patients with overactive bladder: Extension of a prospective open-label study

INTRODUCTION

We evaluate the efficacy and safety of solifenacin to treat incontinence in children with non-neurogenic (DO) or neurogenic detrusor overactivity (NDO) refractory to oxybutinin or tolterodine.

METHODS

We updated and extended our previously published non-randomized uncontrolled study on open-label use of adjusted-dose regimens of solifenacin (1.25-10 mg) in children with refractory incontinence. The follow-up included voiding diaries, post-void residuals, urine cultures, ultrasounds and urodynamic studies. Clinical data were updated as of September 2012. Subjective improvement was assessed with the Patient Perception of Bladder Condition (PPBC) scale. The primary end point was efficacy toward continence and secondary end points were tolerability and safety.

RESULTS

Overall, 244 patients (112 girls, 132 boys) were enrolled; 53 with NDO and 191 with DO. Minimal follow-up was 5 months, the mean duration of treatment was 21.0 months and the mean age at initiation was 9.2 years. Urodynamic capacity improved from 145 ± 76 mL to 339 ± 152 mL and the amplitude of uninhibited contractions decreased from 66 ± 26 to 20 ± 20 cmH2O (p < 0.0001). The overall success rate is 91%, and more specifically 94% for non-neurogenic and 79% for neurogenic, which is significantly different (p = 0.013). Twenty-three patients discontinued treatment for unsatisfactory clinical response or bothersome side effects. No side effects were reported by 175 patients, mild by 46, moderate by 9, and 14 withdrew due to their side effects. Ten patients developed post-void residuals of ≥20 mL.

CONCLUSION

Although higher in the non-neurogenic group, high subjective and objective success rates were maintained over a longer follow-up with an adjusted-dose regimen of solifenacin to treat pediatric NDO or DO refractory to oxybutynin or tolterodine. Moreover, we found acceptable tolerability and safety profiles.

Five years of experience in nocturnal enuresis and urinary incontinence in children: where we are and where we are going

BACKGROUND

Nocturnal enuresis (NE) is a very common pediatric disorder. The aim of this study was to evaluate the characteristics of patients with NE or urinary incontinence (UI) during a period of 5 years to increase the knowledge on these conditions and optimize their diagnosis and treatment.

METHODS

We enrolled 278 children with NE or UI referred to the pediatric nephrology ambulatory, 'A. Gemelli' University Hospital of Rome, from December 2006 to December 2011.

RESULTS

We observed that heredity, parasomnias, left-handedness, polythelia and constipation are correlated to NE and UI.

CONCLUSIONS

We wanted to clarify the definition of NE and UI and describe our experience on the main characteristics of these conditions by referring to the latest knowledge reported in the literature.

Vesicoureteral reflux--the role of bladder and bowel dysfunction

Vesicoureteral reflux (VUR) is a significant risk factor for clinical pyelonephritis and renal scarring. In 2010, the American Urological Association (AUA) reported that bladder and bowel dysfunction (BBD), which is common in patients with VUR, increases the risk of breakthrough UTI in children receiving antibiotic prophylaxis, reduces the success rate for endoscopic injection therapy, and increases the risk of postoperative UTI, irrespective of the surgical success rate for VUR. Accordingly, physicians are strongly recommended to investigate BBD in their patients with VUR. Symptoms and signs of BBD include urinary frequency and urgency, prolonged voiding intervals, daytime wetting, perineal and penile pain, holding manoeuvres (posturing to prevent wetting), constipation, and encopresis. Primary assessment tools include the Pediatric Symptom Checklist, urinalysis, urine culture, bladder diary, measurement of the postvoid residual urine volume, Dysfunctional Voiding Symptom Score, uroflow with electromyography, and Bristol Stool Form Score. The Rome III criteria can also be used for diagnostic assessment of bowel function. Treatment of BBD should be individualized, directed at symptomatic and objective improvement, and can include behavioural modification, biofeedback, selective use of anticholinergics and α-blockers, and bowel management.

Bladder and bowel dysfunction: evidence for multidisciplinary care

PURPOSE

We examined the symptoms of bladder-bowel dysfunction (ie severity of voiding dysfunction and stool consistency) and psychosocial difficulties in children presenting to the pediatric urology clinic for voiding dysfunction and to the pediatric gastroenterology clinic for functional constipation.

MATERIALS AND METHODS

Parents of children seen at the gastroenterology clinic were recruited during the outpatient clinic appointment, and parents of children seen at the urology clinic were randomly selected from the research database and matched to the gastroenterology sample based on age and gender of the child. All parents completed the Dysfunctional Voiding Scoring System, Bristol Stool Form Scale, Pediatric Symptom Checklist and Parenting Stress Index™-Short Form, which assessed severity of voiding dysfunction, stool consistency, level of psychosocial difficulties and level of parenting stress, respectively.

RESULTS

Children seen at the urology and gastroenterology clinics did not differ significantly on any of the measures, indicating that the severity of their bladder-bowel dysfunction is similar. However, they had significantly more severe voiding dysfunction, more constipated stool and more psychosocial difficulties than historical healthy controls. Additionally, level of parenting stress was significantly correlated with patient level of psychosocial difficulties and severity of voiding dysfunction.

CONCLUSIONS

Patients with bladder and bowel dysfunction represent a homogeneous group that would potentially benefit from a multidisciplinary treatment approach involving urology, gastroenterology and psychology professionals.

Lower health related quality of life and psychosocial difficulties in children with monosymptomatic nocturnal enuresis--is snoring a marker of severity?

PURPOSE

Sleep disordered breathing in children is linked to numerous negative psychosocial consequences, including lower health related quality of life, increased behavioral problems and impaired neuropsychological functioning. We examined whether snoring, which is the least severe form of sleep disordered breathing, or health related quality of life could account for the increased rate of psychosocial difficulty in children with monosymptomatic nocturnal enuresis.

MATERIALS AND METHODS

Patients diagnosed with monosymptomatic nocturnal enuresis seen at an outpatient pediatric urology clinic completed measures of health related quality of life (Obstructive Sleep Apnea Syndrome-18-Item Questionnaire), sleep disordered breathing (Pediatric Sleep Questionnaire) and psychosocial difficulty (Pediatric Symptom Checklist). Patients were categorized into 2 groups (snoring vs no snoring) based on the Pediatric Symptom Checklist snoring subscale score.

RESULTS

Included in the study were 62 males and 45 females with a mean ± SD age of 9.09 ± 2.58 years and a mean body mass index of 21.00 ± 6.93 kg/m(2) (range 13 to 49). The sample was evenly split between 56 snorers (52.3%) and 51 nonsnorers (47.7%). Compared to children with monosymptomatic nocturnal enuresis who did not snore, MANCOVA results revealed that patients with monosymptomatic nocturnal enuresis who snored had significantly more externalizing problems and total psychosocial problems, in addition to significantly more impairment in all areas of health related quality of life.

CONCLUSIONS

Snoring in children with monosymptomatic nocturnal enuresis puts them at increased risk for behavioral and psychosocial problems, in addition to impaired health related quality of life. These findings support the need for future studies of the neurological links between sleep disordered breathing and monosymptomatic nocturnal enuresis.
