The overlooked association between lower urinary tract dysfunction and psychiatric disorders: a short screening test for clinical practice

Prevalence of pediatric lower urinary tract symptoms in a national claims database of privately insured patients, 2003-2014

BACKGROUND

We conducted this study to estimate the prevalence of pediatric lower urinary tract symptoms (pLUTS) in a US privately insured pediatric population who are 6-20 years old by age, sex, race/ethnicity from 2003-2014. This has not been previously described in the literature.

METHODS

We retrospectively reviewed Optum's de-identified Clinformatics® Data Mart Database between 2003-2014. A pLUTS patient was defined by the presence of ≥ 1 pLUTS-related ICD-9 diagnosis code between the age of 6-20 years. Neurogenic bladder, renal transplant and structural urologic disease diagnoses were excluded. Prevalence by year was calculated as a proportion of pLUTS patients among the total population at risk. Variables reviewed included age, sex, race, geographic region, household factors and clinical comorbidities including attention-deficit/hyperactivity disorder (ADHD), constipation, and sleep apnea. Point of service (POS) was calculated as a proportion of pLUTS-related claims associated with a POS compared to the total claims at all POS in the time period.

RESULTS

We identified 282,427 unique patients with ≥ 1 claim for pLUTS between the ages of 6-20 years from 2003 to 2014. Average prevalence during this period was 0.92%, increasing from 0.63% in 2003 to 1.13% in 2014. The median age group of patients was 6-10 years. More patients were female (59.80%), white (65.97%), between 6 and 10 years old (52.18%) and resided in the Southern US (44.97%). Within a single household, 81.71% reported ≤ 2 children, and 65.53% reported ≥ 3 adults. 16.88% had a diagnosis of ADHD, 19.49% had a diagnosis of constipation and 3.04% had a diagnosis of sleep apnea. 75% of pLUTS-related claims were recorded in an outpatient setting.

CONCLUSIONS

Families consistently seek medical care in the outpatient setting for pLUTS. The demographic and clinical characteristics of our cohort reflect prior literature. Future studies can help define temporal relationships between household factors and onset of disease as well as characterize pLUTS-related healthcare resource utilization. Additional work is required in publicly insured populations.

Personal hygiene, environmental conditions, and toilet use of children in primary schools: A cohort study

BACKGROUND

Many primary school children withhold urine and stool whilst at school for various reasons. Limited toilet access and the failure to provide safe, sanitary toilets are putting children at risk for toilet avoidance behavior.

OBJECTIVE

We aimed to examine personal hygiene, environmental conditions, the perception of these on children, and their toilet use in primary schools.

STUDY DESIGN

Children aged 6-12 and their parents were asked to complete a self-report questionnaire regarding toilet behavior and the perception of school toilet standards.

RESULTS

The main findings are listed below using the data from the questionnaire.

DISCUSSION

We found that 9% and 63% of the children avoided urination and defecating at school, respectively. Similar results were reported previously. The participants' perceptions regarding the environmental conditions of school toilets and conditions revealed that 34% of the children felt that the toilets were dirty or very dirty. Around one-third of them reported a lack of toilet paper sometimes or most of the time. These unsatisfying hygienic conditions of school toilets can be easily solved. Unfortunately, 46% of the children in our study experienced bullying in school toilets. These worrisome data are seldom reported in other studies. The urination habits of the girls, who mostly preferred to partially squat or stand may lead to dysfunctional voiding and incomplete bladder emptying. Our study was limited by the relatively small population, the subjectiveness of the self-reporting questionnaire, and the voiding and defecation habits of the investigated children during school hours. These hours do not necessarily reflect the children's habits after school hours and during the weekends. Despite these limitations, the discussed issues regarding personal hygiene and the environmental conditions in the sampled primary schools are extremely important.

CONCLUSION

Nearly half of the school children had negative perceptions of school toilets. This should raise awareness and concern for school staff to consider and investigate potential facilities improvement in light of the impact observed here. Implementation of appropriate education and a better environment of toilet facilities and security is important for the children's well-being.

Prevalence of pediatric lower urinary tract symptoms in a US population seeking medical care, 2003- 2014

Background

We conducted this study to estimate the prevalence of pediatric lower urinary tract symptoms (pLUTS) in a US privately-insured pediatric population who are 18 years of age or older by age, sex, race/ethnicity from 2003-2014. This has not been previously described in the literature.

Methods

We retrospectively reviewed Optum's de-identifed Clinformatics® Data Mart Database database between 2003-2014. A pLUTS patient was defined by the presence of ≥ 1 pLUTS-related ICD-9 diagnosis code between the age of 6-20 years. Neurogenic bladder, renal transplant and structural urologic disease diagnoses were excluded. Prevalence by year was calculated as a proportion of pLUTS patients among the total population at risk. Variables reviewed included age, sex, race, geographic region, household factors and clinical comorbidities including attention-deficit/hyperactivity disorder (ADHD), constipation, and sleep apnea. Point of service (POS) was calculated as a proportion of pLUTS-related claims associated with a POS compared to the total claims at all POS in the time period.

Results

We identified 282,427 unique patients with ≥ 1 claim for pLUTS between the ages of 6-20 years from 2003-2014. Average prevalence during this period was 0.92%, increasing from 0.63% in 2003 to 1.13% in 2014. Mean age was 12.15 years. More patients were female (59.80%), white (65.97%), between 6-10 years old (52.18%) and resided in the Southern US (44.97%). Within a single household, 81.71% reported ≤ 2 children, and 65.53% reported ≥ 3 adults. 16.88% had a diagnosis of ADHD, 19.49% had a diagnosis of constipation and 3.04% had a diagnosis of sleep apnea. 75% of pLUTS-related claims were recorded in an outpatient setting.

Conclusions

Families consistently seek medical care in the outpatient setting for pLUTS. The demographic and clinical characteristics of our cohort reflect prior literature. Future studies can help define temporal relationships between household factors and onset of disease as well as characterize pLUTS-related healthcare resource utilization. Additional work is required in publicly-insured populations.

Attention-Deficit/Hyperactivity Disorder Is Associated With Increased Rates of Childhood Infectious Diseases: A Population-Based Case-Control Study

OBJECTIVE

Infectious diseases (IDs) pose a heavy burden on children. An association between pediatric attention-deficit/hyperactivity disorder (ADHD) and specific IDs has been documented. Our objective was to test the possibility that ADHD is associated with increased likelihood for pediatric IDs at large.

METHOD

A population-based case-control study was conducted using Electronic Medical Records (EMRs) of a national Health Maintenance Organization, Leumit Health Services (LHS). ICD-9/10 criteria were used for all diagnoses. The study population consisted of all children and adolescents (aged 5-18 years), members of LHS between January 1, 2006-June 30, 2021. Case patients met International Classification of Diseases (ICD-9/10) criteria for ADHD. Controls included randomly selected persons without ADHD (2:1 ratio), matched individually by demographic indices. The EMRs retrieved 3 exposure categories: pediatric ID, anti-infective medications use, and number of physician visits. The study was approved by the review board of Shamir Medical Center and the Research Committee of LHS.

RESULTS

Cases patients comprised 18,756 participants, with a mean age of 8.3 ± 2.6 years and a male/female ratio of 63%:37%. Matched controls comprised 37,512 participants, with a mean age of 8.3 ± 2.6 years and a male/female ratio of 63%:37%. Demographic variables were similar between the groups. The rates of all IDs were significantly higher in participants with ADHD than in controls and were not restricted to a single body system, including acute respiratory infection (OR = 1.4, 95% CI = 1.3-1.4, p < .001), acute gastroenteritis (OR = 1.3,95% CI 1.3-1.4, p < .001), salmonellosis (OR = 2.8, 95% CI = 2.3-3.5, p < .001), and urinary tract infection (OR = 1.3, 95% CI = 1.2-1.4, p < .001). All anti-infective agents were prescribed significantly more often to children with ADHD. There were significantly higher rates of physician visits for participants with ADHD.

CONCLUSION

Study findings suggest an association between ID and pediatric ADHD Health care providers should be aware of this potential association.

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.

Association between lower urinary tract symptoms (LUTS) and obsessive-compulsive disorders (OCD) in women: A study based on urodynamic findings and micturition problem

AIM

This study focused on women with chronic lower urinary tract symptoms (LUTS) who simultaneously suffered from obsessive-compulsive disorder (OCD) to evaluate the association between micturition abnormality and OCD.

METHODS

A cohort case study was conducted on 128 women with chronic LUTS who visited the academic clinic from 2012 to 2018. The participants with a history of OCD were grouped together, whereas the other group consisted of those with no psychiatric issues. Data were analyzed using the Kolmogorov-Smirnov test and also the nonparametric Kruskal-Wallis and χ² tests.

RESULTS

The participants with OCD had a lower mean age (41.7 vs. 48.8 years) and longer symptom duration than the control group. Moreover, voiding phase problems were more prevalent among OCD patients (mean voiding score: 9.3 vs. 6.9). Urge urinary incontinence (UUI) was the most common type of urinary incontinence in OCD patients, and the most important urodynamic study finding was bladder outlet obstruction (45% and 17% in the OCD and control groups, respectively). Voiding disorders resulted in chronic renal failure in two patients (3.12%). It was shown that bladder outlet obstruction (odds ratio (OR) 4.43, 95% confidence interval [CI] 1.53-12.78, p = 0.006] was the strongest predictor of OCD and stress urinary incontinence (OR 0.20, 95% CI 0.07-0.53, p < 0.001) was the best protector against OCD.

CONCLUSION

The findings revealed that chronic LUTS was related to voiding dysfunction and urodynamic abnormality in OCD patients. These disorders may be categorized as somatoform disorder that requires appropriate treatments.

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.

Dysfunctional voiding: update on evaluation and treatment

PURPOSE OF REVIEW

This review will be covering dysfunctional voiding, its diagnosis, and treatment options. This will focus primarily on dysfunctional voiding rather than all lower urinary tract dysfunction and we will focus on some of the newer findings and progress within this disease.

RECENT FINDINGS

Dysfunctional voiding is the inappropriate sphincter and pelvic floor constriction during voiding in an otherwise neurologically normal child. This has a wide spectrum of symptoms and can lead to a number of complications such as chronic kidney disease and poor quality of life if not appropriately addressed. Dysfunctional voiding is diagnosed with a careful examination and history with further imaging including a renal ultrasound and uroflowmetry to confirm the diagnosis. Urotherapy and biofeedback are the first and second-line treatments respectively and lead to significant improvement or cure in the majority of patients. For refractory patients, additional therapy options include use of α-blockers, botulinum injection, and electroneurostimulation, though the majority of the literature surrounding the use of these therapies consists of small studies with heterogenous causes of voiding dysfunction.

SUMMARY

Dysfunctional voiding is a common urologic complaint that has many excellent options for improving the patient's voiding issues and should be considered in patients with voiding dysfunction.

Diagnosis and Management of Bladder Dysfunction in Neurologically Normal Children

Normal bladder and urethral sphincter development as well as neural/volitional control over bladder-sphincter function are essential steps for regular lower urinary tract function. These maturational sequences are clinically evident by the age of 5 years. However, in 17-22% of children, symptoms persist beyond that age, characterizing lower urinary tract dysfunction (LUTD). The clinical spectrum is wide and includes overactive bladder, voiding postponement, underactive bladder, infrequent voiding, extraordinary daytime only urinary frequency, vaginal reflux, bladder neck dysfunction, and giggle incontinence. LUTD may lead to vesicoureteral reflux and recurrent urinary tract infections, increasing the likelihood of renal scarring. LUTD is often associated with constipation and emotional/behavioral disorders such as anxiety, depression, aggressiveness, and social isolation, making diagnosis, and treatment imperative. Diagnosis of LUTD is essentially based on clinical history, investigation of bladder storage, voiding symptoms (urinary frequency, daytime incontinence, enuresis, urgency) and constipation. Dysfunctional Voiding Score System (DVSS) is a helpful tool. Physical examination focuses on the abdomen to investigate a distended bladder or palpable fecal mass, the lumbosacral spine, and reflex testing. Bladder diaries are important for recording urinary frequency and water balance, while uroflowmetry is used to assess voided volume, maximum flow, and curve patterns. Bladder ultrasonography to measure post-void residual urine volume and urodynamics are used as supplemental tests. Current first line treatment is urotherapy, a combination of behavioral measures to avoid postponing micturition, and a restricted diet for at least 2 months. Anticholinergics, β3 agonists and neuromodulation are alternative therapies to manage refractory overactive bladder. Cure rates, at around 40%, are considered satisfactory, with daytime symptoms improving in 32% of cases. Furthermore, children who are also constipated need treatment, preferentially with polyethylene glycol at doses of 1-1.5 g/kg in the 1st 3 days and 0.25-0.5 g/kg thereafter until the 2-month period of behavioral therapy is complete. If urotherapy fails in cases of dysfunctional voiding, the next step is biofeedback to teach the child how to relax the external urethral sphincter during micturition. Success rate is around 80%. Children with underactive bladder usually need a combination of clean intermittent catheterization, alpha-blockers, biofeedback and neuromodulation; however, cure rates are uncertain.
