Quantifying demographic, urological and behavioral characteristics of children with lower urinary tract symptoms

Who needs an ultrasound? Using patient symptom questionnaire & UTI history to determine when to obtain an RBUS in children with non-neurogenic lower urinary tract dysfunction

INTRODUCTION

Non-neurogenic lower urinary tract dysfunction (LUTD) is one of the most common reasons for presentation to a pediatric urologist, affecting up to 20% of children. Predicting who will benefit from RBUS as part of their work-up is challenging as the majority will have normal imaging.

OBJECTIVE

Our objective was to assess the utility of using the Dysfunctional Voiding and Incontinence Scoring System (DVISS) and urinary tract infection (UTI) history to predict which LUTD patients were most likely to have an abnormal RBUS as well as determine a DVISS cutoff to aid in making this prediction. We hypothesized that higher DVISS scores and a positive urinary tract infection (UTI) history would be associated with increased likelihood of RBUS abnormality.

STUDY DESIGN

We retrospectively reviewed outpatients seen for LUTD from 5/2014-1/2016 who received an RBUS. Association between prior UTI, DVISS score, gender, and race and RBUS abnormality were evaluated using logistic regression analysis. Receiver operating characteristic (ROC) curves were created to evaluate the predictive model and a Youden index calculated to determine the optimal cutoff for DVISS score to predict abnormal RBUS.

RESULTS

15 of 333 patients (4.5%) had a clinically significant RBUS abnormality. Significantly more patients with abnormal RBUS had a positive UTI history and median DVISS was higher. UTI history and DVISS score were associated with RBUS abnormality whereas neither gender nor race were. A DVISS score cutoff of 12 was determined to be ideal for predicting abnormal imaging. Using DVISS≥12 and positive UTI history, patients with both risk factors were significantly more likely to have an abnormal RBUS than those with zero or one risk factor (Figure).

DISCUSSION

To the best of our knowledge this is the first study to try to identify risk factors associated with RBUS abnormality in pediatric LUTD patients and create an evidence-based approach to imaging these patients. We found both DVISS cutoff ≥12 and positive UTI history to be useful to risk stratify LUTD patients' likelihood of abnormal RBUS. Limitations include the study's retrospective nature as well as the fact the population was drawn from a tertiary care pediatric hospital with a large referral population and the fact that the decision to order an RBUS was based on individual clinician preference and decision making.

CONCLUSIONS

We found that DVISS score≥12 and UTI history are useful in guiding the decision to obtain RBUS in pediatric LUTD patients.

Investigation of urinary disorders, functional independence, and quality of life in children with cerebral palsy

PURPOSE

The study aimed to investigate the relationship between voiding disorders, functional independence, and quality of life, according to the gross motor function classification system, in children with cerebral palsy (CP) aged 8-17.

METHODS

A total of 102 individuals (aged 8-17) with CP were included in the study. The Gross Motor Function Classification System (GMFCS), Dysfunctional Voiding and Incontinence Scoring System (DVISS), Wee Functional Independence Measure for Children (WeeFIM), and Pediatric Quality of Life Inventory (PedsQL) were used to evaluate the clinical parameters.

RESULTS

There is a statistically significant difference in DVISS (p = 0.010), WeeFIM (p = 0.001), and PedsQL (p = 0.001) scores of individuals with CP regarding GMFCS. According to the CP classification, there is a statistically significant difference between WeeFIM (p = 0.001) and PedsQL (p = 0.020) scores. Besides, there is a significant difference between DVISS (p = 0.048), WeeFIM (p = 0.001) and PedsQL (p = 0.001) according to the ambulation status of individuals with CP. On the other hand, there is a positive moderate, statistically significant correlation between WeeFIM and PedsQL scores (ρ = 0.306, r = 0.002). A moderately negative statistically significant relationship exists between PedsQL and DVISS (ρ = -0.266, r = 0.007). A negative, moderate, statistically significant correlation was shown between DVISS and WeeFIM scores (ρ = -0.323, r = 0.001).

CONCLUSIONS

As the gross motor functional level of individuals with CP increased, voiding dysfunction increased; on the other hand, functional independence and quality of life decreased.

Impact of Neurodevelopmental Disorders on Bowel Management Outcomes in Children with Functional Constipation

OBJECTIVES

Patients experiencing functional constipation (FC) can participate in structured bowel management programs (BMPs) to manage constipation or fecal incontinence when standard management fails. We sought to evaluate the efficacy of BMPs for children with FC with and without neurodevelopmental disorders.

METHODS

We performed a retrospective review of children with FC who participated in our BMP from 2014 to 2021. Stool/urinary continence, bowel regimen, surgical history, parent-reported outcomes measures (PROMs: Cleveland Clinic Constipation Score, Baylor Continence Scale, Vancouver Symptom Score for Dysfunctional Elimination), and Pediatric Quality of Life Inventory (PedsQL) were assessed pre- and at least 9 months post-BMP.

RESULTS

The cohort included 156 patients with a median age of 9 years and follow-up of 627 days (IQR: 389-808 days). Two sub-cohorts included patients with FC only (69%) and FC plus a neurodevelopmental disorder (31%): 59% attention-deficit/hyperactivity disorder, 33% autism spectrum disorder, and 8% obsessive-compulsive disorder. Both groups had significantly improved follow-up bowel movement frequency and continence (39%-90% neurodevelopmental, 44%-82% FC only, P < 0.001) and urinary continence (65%-90% neurodevelopmental, 69%-91% FC only, P < 0.02). There was a significant improvement in most of the PROMs at follow-up. Both groups experienced a clinically meaningful improvement in overall PedsQL scores (pre- and postBMP difference of >4.5).

CONCLUSIONS

Patients with FC with and without a neurodevelopmental disorder had significant improvement in stool and urinary continence after undergoing a BMP. Further studies are needed to see if this improvement is durable over a longer period of time in this challenging cohort.

Impact of Race, Gender, and Socioeconomic Status on Symptom Severity at Time of Urologic Referral

BACKGROUND AND OBJECTIVES

The Dysfunctional Voiding and Incontinence Scoring System (DVISS) is a validated tool to evaluate lower urinary tract dysfunction (LUTD) severity in children. DVISS provides a quantitative score (0-35) including a quality-of-life measure, with higher values indicating more/worse symptoms. Clinically, variability exists in symptom severity when patients present to pediatric urology with LUTD. We hypothesized that symptom severity at consultation varied based on race, gender, and/or socioeconomic status.

METHODS

All urology encounters at a single institution with completed modified DVISS scores 6/2015-3/2018 were reviewed. Initial visits for patients 5-21 years old with non-neurogenic LUTD were included. Patients with neurologic disorders or genitourinary tract anomalies were excluded. Wilcoxon rank sum tests compared scores between White and Black patients and between male and female patients. Multiple regression models examined relationships among race, gender, estimated median household income, and insurance payor type. All statistics were performed using Stata 15.

RESULTS

In total, 4086 initial patient visits for non-neurogenic LUTD were identified. Median DVISS scores were higher in Black (10) versus White (8) patients (p < 0.001). Symptom severity was higher in females (9) versus males (8) (p < 0.001). When estimated median income and insurance payer types were introduced into a multiple regression model, race, gender, and insurance payer type were significantly associated with symptom severity at presentation.

CONCLUSIONS

Race, gender, and socioeconomic status significantly impact LUTS severity at the time of urologic consultation. Future studies are needed to clarify the etiologies of these disparities and to determine their clinical significance.

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.

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.

Recognition and management of bladder bowel dysfunction in children with autism spectrum disorder

Children with autism spectrum disorder (ASD) with rigidities, anxiety or sensory preferences may establish a pattern of holding urine and stool, which places them at high risk of developing bladder bowel dysfunction (BBD). BBD, despite being common, is often unrecognised in children with ASD. With this case report of a 7-year-old girl with ASD presenting with acute retention of urine, we attempt to understand the underlying factors which may contribute to the association between BBD and ASD. Literature review indicates a complex interplay of factors such as brain connectivity changes, maturational delay of bladder function, cognitive rigidities and psychosocial stressors in children with ASD may possibly trigger events which predispose some of them to develop BBD. Simple strategies such as parental education, maintaining a bladder bowel diary and treatment of constipation may result in resolution of symptoms.

Quality of life in enuretic children

INTRODUCTION

Nocturnal enuresis is a highly incident chronic disorder that generates countless problems to the child and their parents. Bed-wetting has significant negative impacts on self-esteem and the performance of children. The aim of the current study is to assess the quality of life of enuretic children, as well as its association to sex and age.

PATIENTS AND METHODS

Thirty-nine enuretic children (23 boys) and 49 healthy children (27 boys) without any history of previous treatment for enuresis or voiding dysfunction were included. Age ranged between 6 and 11 years old. The "AUQEI" questionnaire was applied in a private environment to all children by the same researcher (psychologist) to evaluate quality of life.

RESULTS

Enuretic children displayed loss in quality of life when compared to non-enuretic (35.9% of enuretic x 16.3% of non-enuretic, p=0.035). They were mostly affected in their daily activities (p=0.02). No significant differences were found in the association of sex and gender with quality of life. These results suggest that, children with nocturnal enuresis have 2.87 times more chances of having loss in quality of life compared to non-enuretic.

CONCLUSIONS

Enuresis has a great impact in quality of life of children. This impact is not related to the age or sex of the child.

Multi-Organ Dysfunction in Cerebral Palsy

Cerebral Palsy (CP) describes a heterogenous group of non-progressive disorders of posture or movement, causing activity limitation, due to a lesion in the developing brain. CP is an umbrella term for a heterogenous condition and is, therefore, descriptive rather than a diagnosis. Each case requires detailed consideration of etiology. Our understanding of the underlying cause of CP has developed significantly, with areas such as inflammation, epigenetics and genetic susceptibility to subsequent insults providing new insights. Alongside this, there has been increasing recognition of the multi-organ dysfunction (MOD) associated with CP, in particular in children with higher levels of motor impairment. Therefore, CP should not be seen as an unchanging disorder caused by a solitary insult but rather, as a condition which evolves over time. Assessment of multi-organ function may help to prevent complications in later childhood or adulthood. It may also contribute to an improved understanding of the etiology and thus may have an implication in prevention, interventional methods and therapies. MOD in CP has not yet been quantified and a scoring system may prove useful in allowing advanced clinical planning and follow-up of children with CP. Additionally, several biomarkers hold promise in assisting with long-term monitoring. Clinicians should be aware of the multi-system complications that are associated with CP and which may present significant diagnostic challenges given that many children with CP communicate non-verbally. A step-wise, logical, multi-system approach is required to ensure that the best care is provided to these children. This review summarizes multi-organ dysfunction in children with CP whilst highlighting emerging research and gaps in our knowledge. We identify some potential organ-specific biomarkers which may prove useful in developing guidelines for follow-up and management of these children throughout their lifespan.

Bladder and bowel symptoms experienced by children with osteogenesis imperfecta

OBJECTIVE

To estimate the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms experienced by children with osteogenesis imperfecta and to describe the socio-demographic and clinical profile of these children.

METHOD

A descriptive study was conducted with a convenience sample of parent-child pairs of toilet-trained children aged from 3 to 18 years. Pairs were interviewed using three tools: (1) Socio-Demographic and Clinical Questionnaire; (2) Dysfunctional Voiding Scoring System; (3) Rome III Criteria along with the Bristol Stool Scale. Data were stratified by socio-demographic and clinical variables and analyzed using descriptive statistics.

RESULTS

Thirty-one parent-child pairs participated in the study; 38.7% (n=12) children reported bowel symptoms, 19.4% (n=6) reported a combination of bladder issues (such as holding maneuvers and urgency) and bowel symptoms (such as hard or painful bowel movements and large diameter stools). There were no reports of isolated bladder issues. Among the child participants, 16 (51.7%) identified as female and 20 (64.5%) were 5-14 years old. The most prevalent type of osteogenesis imperfecta was type III (n=12; 38.7%) and eight (25.8%) children reported using a wheelchair.

CONCLUSION

This is the first study to examine the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms in children with osteogenesis imperfecta, offering a preliminary socio-demographic and clinical profile of these children. This research is an important step toward effective screening, detection, and access to care and treatment, especially for clinicians working with this group of very fragile patients.

Complete resolution of urinary incontinence with treatment improved the health-related quality of life of children with functional daytime urinary incontinence: a prospective study

Background

To assess the health-related quality of life (HRQOL) of children with daytime urinary incontinence (DUI) based on pre- and post-treatment self-reports and parent proxy-reports.

Methods

The study population comprised 117 children with at least one episode of DUI per week and their caregivers as well as 999 healthy children (control group). The Pediatric Quality of Life Inventory 4.0 (PedsQL) questionnaire was administered to assess the HRQOL of children. To assess the degree of improvement in HRQOL, we categorized children into two groups: group A achieved complete response (CR) to treatment within 12 months and group B did not achieve CR within 12 months. CR was defined as the complete resolution of symptoms or alleviation of symptoms to < 1 DUI episode/month.

Results

Valid responses were collected from 84 children [53 boys and 31 girls; mean age: 7.9 ± 1.5 years (range, 6–12)]. Sixty-two patients (73.8%) were classified into group A and 22 (26.1%) into group B. Based on self-reports, significant post-treatment improvement was observed in the scores of all PedsQL items (mean total score: 82.2 ± 11.3 vs. 87.2 ± 9.8; P = 0.003). Group A showed significant improvement in the scores of all PedsQL items after achievement of CR based on child self-reports; however, this was improvement not observed in group B.

Conclusions

To the best of our knowledge, this is the first study to demonstrate the complete resolution of DUI with treatment for improving the HRQOL of these children.

Pupillometric assessment of dysautonomia in pediatric bowel and bladder dysfunction: a pilot study

Bowel and bladder dysfunction (BBD) refers to a heterogeneous group of voiding disorders, accounting for an estimated 40% of pediatric urology visits. Symptoms of BBD include enuresis, urgency, and urinary retention, often accompanied by constipation. The aim of this pilot study was to explore whether a pupillary response can be characterized for BBD, by examining the pupillary light reflex (PLR) before and after voiding among patients with BBD. A total of 28 patients aged from 7 to 21 years were recruited from the Wetting, Infections, and Stooling Help clinic at Children's National Medical Center. An infrared pupilometer was used to assess the PLR. Both baseline static and dynamic pupillometry assessments were obtained before and after voiding. Measurements were also taken after 5 min in the supine position, followed by 5 min standing to induce an orthostatic stressor. Visual inspection of the graphed data revealed a characteristic shape in 11 of 28 patients with voiding symptoms. In these 11 patients, the redilation arm of the PLR shows a 'notch,' or a brief reconstriction of the pupil before resting pupil size is reestablished (figure). This feature of the PLR has not been seen in previous and parallel studies using pupillometry to evaluate other populations. The results of this study suggest that a subset of patients with BBD may have a significant perturbation of autonomic regulation, identifiable through analysis of the PLR. To our knowledge, this 'notch' during redilation has not been previously described or seen in other patient populations and may represent a distinctive and readily identifiable physiologic marker of disease. These results are broadly aligned with results of other studies that have examined ANS activity in patients with BBD, although further study is needed to confirm the results of this pilot study and to assess relative contributions of sympathetic and parasympathetic function in producing pupillary abnormalities. This study has several limitations, including the small sample size, the absence of data on severity and duration of symptoms, and the absence of a control group of patients without any voiding symptoms. A simple tool for diagnosing BBD and for monitoring response to treatment could significantly improve the quality of treatment for one of the most common pediatric urologic complaints. Given the heterogeneity of symptoms under the BBD umbrella, pupillometric data could guide selection of treatment options, as well as assess adequacy of response to pharmacologic therapy.

The Role of Non-invasive Testing in Evaluation and Diagnosis of Pediatric Lower Urinary Tract Dysfunction

PURPOSE OF REVIEW

The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike. In the current review, we summarize the important role non-invasive testing plays in the diagnosis and management of children with LUTD and to show how use of these tests can help avoid the need for more invasive testing in the majority of children.

RECENT FINDINGS

Non-invasive tests such urine studies, uroflowmetry ± simultaneous electromyography, assessment of post-void residual, renal/bladder ultrasound, and pelvic ultrasound when used appropriately can provide valuable information to facilitate decision making during the evaluation of children with LUTD. While these tests should be employed prior to more invasive testing such as urodynamic studies, they can often act as a surrogate for the more invasive tests. Non-invasive tests can help us in our goal of improving diagnostic ability to better classify the child's LUTD into an actual condition which allows targeted treatment in the hope of better outcomes and more satisfied patients and families.

Is robot-assisted laparoscopic bilateral extravesical ureteral reimplantation associated with greater morbidity than unilateral surgery? A comparative analysis

INTRODUCTION

Voiding dysfunction after bilateral extravesical ureteral reimplantation for vesicoureteral reflux has long remained a concern. Robotic approach with improved visualization that enables focused and minimal dissection may help with this concern.

OBJECTIVES

To compare postoperative outcomes after bilateral robot-assisted laparoscopic ureteral reimplantation to unilateral robot-assisted laparoscopic ureteral reimplantation.

STUDY DESIGN

This was a retrospective study using data abstracted from an institutional review board-approved registry prospectively maintained at our institution since 2012. Patient demographics, preoperative characteristics, and postoperative outcomes were analyzed. Patients with postoperative febrile urinary tract infection (UTI) underwent voiding cystourethrogram (VCUG). Surgical success is defined as absence of febrile UTI or febrile UTI with negative VCUG.

RESULTS

92 patients with a median follow-up of 14 (25th and 75th IQR 5, 28) months. Median operative time (150 vs. 178 min, p = 0.01) and median hospital stay (33 vs. 37 h, p = 0.01) were longer in the bilateral cohort. Weight-adjusted morphine equivalents requirement was also higher in the bilateral group (0.45 vs. 0.59, p = 0.019).

DISCUSSION

Early postoperative voiding dysfunction is influenced by anesthesia, postoperative pain, analgesics, age, surgical dissection, and preoperative voiding issues. Effective preoperative management of voiding dysfunction, minimizing surgical dissection and cautery, and minimizing opiate use will aid improving outcomes after surgery and enable bilateral surgeries on uretero-vesical junction. A robotic approach to facilitate such strategies could help outcomes after bilateral ureteral reimplantation. Limitations of this study include its retrospective design, the absence of routine postoperative VCUG after ureteral reimplantation, and unknown confounding variables.

CONCLUSION

Robot-assisted laparoscopic bilateral extravesical ureteral reimplantation is not associated with an increased risk of postoperative morbidity compared with unilateral surgery.

Bladder and bowel dysfunction in children: An update on the diagnosis and treatment of a common, but underdiagnosed pediatric problem

Bladder and bowel dysfunction (BBD) describes a spectrum of lower urinary symptoms (LUTS) accompanied by fecal elimination issues that manifest primarily by constipation and/or encopresis. This increasingly common entity is a potential cause of significant physical and psychosocial burden for children and families. BBD is commonly associated with vesicoureteral reflux (VUR) and recurrent urinary tract infections (UTIs), which at its extreme may lead to renal scarring and kidney failure. Additionally, BBD is frequently seen in children diagnosed with behavioural and neuropsychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Patients with concomitant BBD and neuropsychiatric disorders have less favourable treatment outcomes. Early diagnosis and treatment of BBD are critical to avoid secondary comorbidities that can adversely impact children's kidney and bladder function, and psychosocial well-being. The majority of patients will improve with urotherapy, adequate fluid intake, and constipation treatment. Pharmacological treatment must only be considered if no improvement occurs after intensive adherence to at least six months of urotherapy ± biofeedback and constipation treatment. Anticholinergics remain the mainstay of medical treatment. Selective alpha-blockers appear to be effective for improving bladder emptying in children with non-neurogenic detrusor overactivity (DO), incontinence, recurrent UTIs, and increased post-void residual (PVR) urine volumes. Alpha-1 blockers can also be used in combination with anticholinergics when overactive bladder (OAB) coexists with functional bladder outlet obstruction. Minimally invasive treatment with onabotulinumtoxinA bladder injections, and recently neurostimulation, are promising alternatives for the management of BBD refractory to behavioural and pharmacological treatment. In this review, we discuss clinical presentation, diagnostic approach, and indications for behavioural, pharmacological, and surgical treatment of BBD in children based on a thorough literature review. Expert opinion will be used when scientific evidence is unavailable.

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.

Clinical course of a cohort of children with non-neurogenic daytime urinary incontinence symptoms followed at a tertiary center

OBJECTIVE

To characterize a cohort of children with non-neurogenic daytime urinary incontinence followed-up in a tertiary center.

METHODS

Retrospective analysis of 50 medical records of children who had attained bladder control or minimum age of 5 years, using a structured protocol that included lower urinary tract dysfunction symptoms, comorbidities, associated manifestations, physical examination, voiding diary, complementary tests, therapeutic options, and clinical outcome, in accordance with the 2006 and 2014 International Children's Continence Society standardizations.

RESULTS

Female patients represented 86.0% of this sample. Mean age was 7.9 years and mean follow-up was 4.7 years. Urgency (56.0%), urgency incontinence (56.0%), urinary retention (8.0%), nocturnal enuresis (70.0%), urinary tract infections (62.0%), constipation (62.0%), and fecal incontinence (16.0%) were the most prevalent symptoms and comorbidities. Ultrasound examinations showed alterations in 53.0% of the cases; the urodynamic study showed alterations in 94.7%. At the last follow-up, 32.0% of patients persisted with urinary incontinence. When assessing the diagnostic methods, 85% concordance was observed between the predictive diagnosis of overactive bladder attained through medical history plus non-invasive exams and the diagnosis of detrusor overactivity achieved through the invasive urodynamic study.

CONCLUSIONS

This subgroup of patients with clinical characteristics of an overactive bladder, with no history of urinary tract infection, and normal urinary tract ultrasound and uroflowmetry, could start treatment without invasive studies even at a tertiary center. Approximately one-third of the patients treated at the tertiary level remained refractory to treatment.

Voiding Dysfunction: What Can Radiologists Tell Patients and Pediatric Urologists?

OBJECTIVE

Imaging children with dysfunctional voiding remains a challenge because 98% of these children have normal anatomy. Identifying the 1-2% of children who do have an anatomic basis for incontinence is important; this article focuses on how pediatric urologists use imaging for the evaluation of patients with this condition.

CONCLUSION

Imaging a patient with dysfunctional voiding can provide findings that will allow an accurate diagnosis and lead to optimal management. The key for the pediatric urologist is using imaging studies judiciously because the diagnostic yield is low. If every patient with dysfunctional voiding who presents to the clinic undergoes imaging, there will be little gain. Understanding in which patients to try imaging sooner versus trying medical and behavioral management first is a function of experience.

Attention deficit-hyperactivity disorder symptoms and daytime voiding symptoms in children with primary enuresis: an observational study to evaluate the effectiveness of desmopressin treatment

Purpose. To evaluate the effectiveness of presence of desmopressin in treating primary enuresis (PE) for children with attention deficit-hyperactivity disorder (ADHD) symptoms. Materials and Methods. Children aged from 5 to 12 years with the chief complaint of PE treated with desmopressin were enrolled in pediatric urology clinics. The parent-reported SNAP-IV questionnaire was used to evaluate ADHD symptoms (cut-off value: 90th percentile). Voiding symptoms were assessed by the Dysfunctional Voiding Scoring System (DVSS) questionnaire. The responses to desmopressin were analyzed in children with and without ADHD symptoms. Results. The study sample comprised 68 children; 27 (39.7%) presented with ADHD symptoms and 41 (60.3%) with non-ADHD symptoms. The children collected from a tertiary referral center may explain the high prevalence of ADHD symptoms in the present study. The total DVSS score in the ADHD symptoms group was significantly higher than in the non-ADHD symptoms group (7.72 versus 5.65, P = 0.05). In the ADHD symptoms group, there were significantly higher score in the “pee 1-2 times/day” and “can't wait” subscales of DVSS and lower sleep quality based on the Pediatric Sleep Quality questionnaire, as well as significantly lower peak flow rate and voided volume. The responses to desmopressin for enuresis were comparable between children with ADHD and non-ADHD symptoms. Conclusions. Approximately 39.7% of PE children presented with ADHD symptoms at urologic clinics. PE children with ADHD symptoms had higher risk of daytime LUTS and comparable response to desmopressin treatment for PE. To evaluate ADHD symptoms and daytime voiding symptoms is important in children with PE.

Chronic social defeat, but not restraint stress, alters bladder function in mice

BACKGROUND

Voiding disorders in humans, particularly in children are associated with increased incidence of behavioral issues as well as past history of childhood abuse. We hypothesized that creating stress in mice, utilizing either a chronic social defeat model (SD) or restraint stress in shallow water model (RSSW) would engender changes in bladder function, morphology, and behavior, thereby enabling us to study the resultant voiding dysfunction.

METHODS

For SD stress (14 days), C57BL/6 male mice were exposed daily to a larger aggressive CD-1 male for 10 min, followed by sensory exposure in a barrier cage for 24h. Control mice were similarly housed with no exposure. For RSSW (21 days), C57BL/6 mice were put in a perforated conical tube with feet immersed in water daily for 4h, then returned to single housing cages. Control mice were also in single housing. After the stress period, voiding patterns were obtained on filter paper, followed by behavioral tests. At necropsy, blood was taken for corticosterone analysis, and bladder and body weights measured. Bladder cryosections were stained with hematoxylin and eosin (H&E) for morphological assessment. Sequential sections were immunostained with antibodies to Ki-67 as a proliferation marker, CD31 (endothelial cell marker), and uroplakin-II. ImageJ software was used to measure bladder wall thickness on blinded H&E photomicrographs as well as quantitate CD31 staining. Both Ki-67-positive and -negative nuclei were counted with Imaris software to obtain a proliferation index.

RESULTS

Only SD mice had a single large void pattern. Bladder-to-body weight ratios increased in SD mice (p≤0.02) but not in RSSW mice. Plasma corticosterone levels were elevated in all stressed mice. SD mice exhibited lower levels of locomotor activity compared with controls; RSSW mice were hyperactive. In SD mice, bladder wall thickness was increased (p ≤ 0.003) but no change was seen in Ki-67 proliferation index, consistent with hypertrophy. No difference with control mice was seen in vascularity as visualized by CD31 staining. Uniform uroplakin-II staining lined the urothelium of both SD and control mice.

CONCLUSIONS

Mice exposed to repeated SD (14 days) respond with altered voiding indicative of urine retention, and exhibit bladder wall changes consistent with hypertrophy while the urothelial barrier is maintained. These changes were not observed with repeated RSSW. SD, in contrast to RSSW, provides a model of psychological stress to further study the interplay of behavior and bladder dysfunction, enabling an improved understanding of voiding dysfunction, and the ability to create innovative and more effective management pathways for children who present with voiding dysfunction.

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.

Objective versus subjective outcome measures of biofeedback: what really matters?

OBJECTIVE

Clinical epidemiologic studies suggest that once established, voiding dysfunction can become a lifelong condition if not treated correctly early on in life. Biofeedback is one component of a voiding retraining program to help children with voiding dysfunction. Our goal was to compare objective non-invasive urodynamic data obtained during office biofeedback sessions with patient reported voiding symptom scores.

METHODS

Charts of 55 children referred in 2010 for pelvic floor muscle biofeedback therapy for urinary incontinence were retrospectively reviewed. Patients with any anatomic diagnoses were excluded. Forty-seven (86%) females and eight males (14%) with a mean age of 8.2 years made up the cohort. Uroflow curves, voided volumes, and post-void residuals were recorded at each visit and served as objective data. Volumes were normalized as a percentage of expected bladder capacity according to age. The patient reported symptom score and patient reported outcome (improved, no change or worse) served as subjective measures of intervention.

RESULTS

The primary referral diagnoses were day and night wetting in 37 (67%) and daytime incontinence in 18 (33%) children. A history of urinary tract infection (UTI) was noted in 32 (64%) patients, and 25% were maintained on antibiotic prophylaxis during the study period. Twenty-nine percent were maintained on anticholinergic medication. Patients attended an average of 2.5 biofeedback sessions. Voided volumes and post void residual volumes were unchanged, 50% of the abnormal uroflow curves normalized over the course of treatment (p < 0.05). Patient reported symptom score decreased from 12.8 ± 5.6 to 8.0 ± 6.5 (p < 0.002) over an average follow-up time of 276 days reflecting fewer daytime voiding symptoms. There was no significant change in the patient symptom score component for the night-time wetting. Patient-reported outcomes at the final session of biofeedback were rated an improved in 26 (47%), no change in 15 (27%), worse in three (5%) patients, and not rated in 11 patients (21%).

CONCLUSIONS

Pelvic floor muscle biofeedback is associated with patient-reported improvement in symptoms, reduction in voiding symptom score, and normalization of uroflow curves, but these improvements are not correlated with objective parameters of voided volumes and post-void residual urine obtained during office visits for biofeedback. It is important to identify the most relevant outcome measures for BFB, as insurance coverage for medical interventions that cannot offer outcomes analysis that demonstrates a benefit for the patient will eventually be eliminated.

Urological Results after Fetal Myelomeningocele Repair in Pre-MOMS Trial Patients at the Children's Hospital of Philadelphia

Introduction: Myelomeningocele patients deal with multiple medical issues, including lower extremity neurological deficits, bowel and bladder incontinence and the sequelae of hydrocephalus secondary to a Chiari II malformation. In utero intervention holds the promise of reversing some of the sequelae and improving outcome. Material and Methods: Between 1998 and 2003 (preceding the formal Management of Myelomeningocele Study, MOMS), an initial group of 58 patients underwent in utero repair of their myelomeningocele between 21 and 25 weeks' gestation. Long-term (5-year) follow-up has occurred in this cohort of patients. Previous reports have documented decreased incidence of ventriculoperitoneal shunting and neuromotor functioning, showing improved outcomes compared with historical controls. Results: Overall, 4 fetal deaths occurred, while the majority of patients returned for follow-up for up to 5 years after closure. Phone follow-up has also been conducted for those who could not return. To date, 10 patients (18.5%) have successfully toilet-trained, while 2 patients have bowel continence and 1 has bladder continence but requires enemas; 2 patients who successfully toilet-trained developed spinal dermoid cysts requiring surgical resection. Discussion: Historically, in utero repair of myelomeningocele patients yields a greater percentage of patients who have achieved continence compared with those undergoing postnatal repair. The MOMS trial will compare contemporary urological outcomes of those patients undergoing either prenatal or postnatal repair in a randomized fashion. The results of this trial showed a decreased need for ventriculoperitoneal shunting in those patients who underwent in utero repair as well as an improvement in lower extremity function.

Management of lower urinary tract dysfunction: a stepwise approach

PURPOSE

To evaluate management patterns of lower urinary tract (LUT) dysfunction and establish a treatment algorithm to guide pediatric healthcare providers.

METHODS

390 children with non-neurogenic LUT dysfunction were followed over 7 months; 115 patients were excluded due to incomplete data. Children were categorized based on presenting complaints and pelvic ultrasound into three groups: daytime urinary incontinence (UI) with complete emptying (CE), UI with incomplete emptying (IE), or IE without UI. Every child underwent behavioral modification (BM) including timed voiding, double voiding, deep breathing, and treatment of constipation if present. BM failures received secondary treatment including medications (alpha blockers, anticholinergics), physical therapy, and/or botulinum toxin type A injection of the external sphincter at a dose of 100 units.

RESULTS

BM improved symptoms in 152 (55%): 68% (46% dry), 49% (27% dry), and 59% (29% dry) from the three groups, respectively. Of the 45% who showed no change in symptoms, 98 (80%) improved with addition of medication, the majority (89) after starting alpha blocker therapy. Children with IE responded better to alpha blockers, 83 (77%) compared to 38% with CE, whereas those with CE demonstrated more symptom resolution with anticholinergics, 6 (38%) compared to 13% of those with IE. Only 6 (2%) patients were refractory to non-operative treatment with all showing improvement after injection of botulinum toxin type A, 4 (67%) of whom became completely dry.

CONCLUSION

Diagnosis of UI and/or IE with stratification of children into particular symptom groups appears beneficial in determining the appropriate therapy for children with LUT dysfunction.

Correlation between symptoms of voiding dysfunction and attention deficit disorder with hyperactivity in children with lower urinary tract symptoms

PURPOSE

We clarified correlations between symptoms of attention deficit disorder with hyperactivity and voiding dysfunction in children.

MATERIALS AND METHODS

The study sample consisted of 92 boys and 38 girls 4 to 14 years old who presented at pediatric urology clinics with untreated lower urinary tract symptoms. Parents completed the Swanson, Nolan and Pelham-IV scale. Each subject with a combined score in the first 2 subscales (inattention, hyperactivity/impulsivity) at or above the 90th percentile was classified as having symptoms of attention deficit disorder with hyperactivity. All other cases were classified as nonattention deficit disorder. Voiding dysfunction symptoms were assessed by the Dysfunctional Voiding Symptom Scale. Sleep quality was assessed by the Pediatric Sleep Questionnaire. We then analyzed correlations between Dysfunctional Voiding Symptom Scale and symptoms of attention deficit disorder with hyperactivity.

RESULTS

The group with symptoms of attention deficit disorder with hyperactivity had significantly higher scores on the Dysfunctional Voiding Symptom Scale overall and in the "cannot wait" subscale compared to the group without attention deficit disorder, as well as poorer sleep quality and lower voiding volumes. Overall Dysfunctional Voiding Symptom Scale scores were significantly correlated with overall Swanson, Nolan and Pelham-IV scale scores and also significantly correlated with each of the 3 Swanson, Nolan and Pelham-IV subscales (inattention, hyperactivity/impulsivity and oppositional defiant). Overall Dysfunctional Voiding Symptom Scale scores and scores on the "cannot wait" and "hurt when pee" subscales were significantly higher for males than for females.

CONCLUSIONS

Boys with higher scores of attention deficit disorder with hyperactivity symptoms tend to have higher Dysfunctional Voiding Symptom Scale scores. Lower urinary tract symptoms were significantly correlated with overall Swanson, Nolan and Pelham-IV scores and significantly correlated with each of the 3 subscales. Evaluation of concomitant symptoms of attention deficit disorder with hyperactivity in children with lower urinary tract symptoms is an important clinical concern.

Correlation between Lower Urinary Tract Scoring System, Behavior Check List, and Bladder Sonography in Children with Lower Urinary Tract Symptoms

Purpose

The Pediatric Lower Urinary Tract Scoring System (PLUTSS) is a standardized questionnaire used for screening and evaluation of the response of children with lower urinary tract symptoms (LUTS) to therapy. We presumed that adding the Child Behavior Check List (CBCL) and bladder volume wall index (BVWI) to the PLUTSS would increase its validity in the detection of children with LUTS.

Materials and Methods

One hundred twenty-two children aged 5 to 15 years with LUTS were enrolled in the study. Seventy-two healthy, age-matched children without urinary complaints were considered as controls. The PLUTSS and CBCL were filled out for all children. Sonography was performed to measure BVWI. Chi-square test and likelihood ratio were used to compare frequencies, receiver operating curve (ROC) analysis was used to evaluate the correlation, and Cohen's kappa was used to measure the agreement between variables. p-values <0.05 were considered significant.

Results

Behavior problems were significantly more common in children with LUTS than in healthy children (p<0.05). The frequency of thick, thin, and normal BVWIs did not differ significantly in the two groups (p>0.05). ROC analysis showed that there was no correlation between PLUTSS, CBCL, and BVWI in either the LUTS subgroup or in the controls (p>0.05). The PLUTSS had the highest sensitivity and specificity, and adding the two other tests decreased its validity for the diagnosis of children with LUTS.

Conclusions

The PLUTSS by itself was the best predictor of LUTS. The CBCL and BVWI were not helpful in making a diagnosis; however, the CBCL was useful in the detection of behavior problems in children with non-monosymptomatic enuresis.

Quality of life of pediatric patients with lower urinary tract dysfunction and their caregivers

The interest in quality of life (QoL) studies has increased as they are useful instruments to evaluate and compare medical care delivery and the impact of health interventions. The perception of QoL differs among individuals. Its characterization is especially difficult in the pediatric age group as each developmental stage presents specific demands. The prevalence of congenital lower urinary dysfunction is high and their management changes the daily routine of the patients and their families. In a cross-sectional study, we evaluated the QoL of 28 children and adolescents with urinary malformations and their caregivers using the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQUEI) and Short-Form 36 (SF-36), respectively, and compared the results with 38 healthy control age-paired children/caregivers. Four questions were added to patients' questionnaire to evaluate issues related to their urological management. Our results show lower AUQUEI total scoring in the patients' group (p<0.0213, Fisher's exact test), who also present problems in dealing with social aspects, such as being at classroom, manifest negative feelings in relation to diurnal urinary losses but seem to be well adapted to intermittent urethral catheterization. A tendency for worse QoL scores in the patients' group caregivers was detected in the SF-36 pain and physical limitation domains.
