Evaluation and treatment of nonmonosymptomatic nocturnal enuresis: a standardization document from the International Children's Continence Society

Transition in enuresis patients: Identifying the gaps and opportunities for the future

BACKGROUND

Nocturnal enuresis is generally considered a children's condition, yet it may persist 1%-2% in adolescence and early adulthood. Refractory patients often demand follow-up by multidisciplinary teams, which is only restricted to some of the expert tertiary centers. However, there are no standardized transition programs/guidelines when follow-up must be passed from pediatric to adult healthcare providers.

AIM, MATERIALS & METHODS

To investigate this issue, we conducted a literature search on enuresis transition, which resulted in no articles. We, therefore, proceeded in a rescue search strategy: we explored papers on transition programs of conditions that may be related and/or complicated by enuresis, nocturia, or other urinary symptoms (chronic diseases, CKD, bladder dysfunction, kidney transplant, neurogenic bladder).

RESULTS

These programs emphasize the need for a multidisciplinary approach, a transition coordinator, and the importance of patient and parent participation, practices that could be adopted in enuresis. The lack of continuity in enuresis follow-up was highlighted when we investigated who was conducting research and publishing on enuresis and nocturia. Pediatric disciplines (50%) are mostly involved in children's studies, and urologists in the adult ones (37%).

DISCUSSION

We propose a stepwise approach for the transition of children with enuresis from pediatric to adult care, depending on the clinical subtype: from refractory patients who demand more complex, multidisciplinary care and would benefit from a transition coordinator up to children/young adults cured of enuresis but who persist in having or present lower urinary tract symptoms (LUTS)/nocturia later on. In any case, the transition process should be initiated early at the age of 12-14 years, with adequate information to the patient and parents regarding relapses or LUTS/nocturia occurrence and of the future treating general practitioner on the enuresis characteristics and comorbidities of the patient.

Parental perception of nocturnal enuresis in a local region of Saudi Arabia

Nocturnal enuresis (NE) has been associated with neurodevelopmental disorders such as autism spectrum disorder, attention deficit or hyperactivity disorder, and intellectual disability. This study aimed to assess parents' perception of NE in children in the eastern region of Saudi Arabia. We conducted a cross-sectional study from May to August 2023, including parents aged ≥18 years living in the area. We administered an online questionnaire to assess parents' knowledge and attitudes toward NE and its treatment. A total of 616 parents completed the questionnaire, 71.4% of which were women, 35% were aged between 25 and 35 years, 75% were married, 65% had a university degree, and 49% had three or more children. In total, 70% demonstrated a good overall knowledge about NE and its treatment, and nearly 60% had a positive attitude toward the condition. Univariate and multivariate ordinal logistic regression analyses revealed that female sex, a higher level of education, and having more than one child were associated with a higher score regarding attitude toward treatment. The level of education and the number of children were predictors of knowledge and a positive attitude toward NE in children.

Assessment of readability and quality of patient education materials specific to nocturnal enuresis

BACKGROUND

Bedwetting, or nocturnal enuresis (NE), is a common childhood disease. Families increasingly turn to free online resources for health education in order to navigate treatment options.

OBJECTIVE

We aim to determine the readability and quality of online health information that families may encounter when searching for information on pediatric NE.

STUDY DESIGN

The search term 'bedwetting' was queried in commonly used search engines. Included articles were further categorized as institutional/reference, commercial, non-profit/charitable, or personal. An online readability platform calculated 3 commonly used readability assessments as well as a consensus score. Quality was assessed by two independent pediatric urologists using a validated DISCERN instrument. Differences in readability were further assessed by article category type.

RESULTS

36 websites were reviewed, 3 did not include treatment options and were not included in quality assessment. 55.6% of the articles were categorized as institutional/reference, 27.8% as non-profit/charitable, 11.1% as personal, and 5.6% as commercial. The average, standard deviation, and range of readability level were as follows: overall consensus score = 9.56 ± 2.09, FK Grade Level Formula score = 9.38 ± 2.17 (range 5.8-14.1), SMOG Index score = 8.89 ± 1.79 (range 6.4-12.9), and the GF Index score = 11.86 ± 2.34 (range 8.4-16.9). The overall consensus score, 9.56, correlates to a 9th-grade reading level. 16 articles were considered to be of 'good' quality, 12 of 'fair' quality, and 5 of 'poor' quality; according to the DISCERN scoring. There was no statistically significant difference in readability scores across website categories. Two articles included the outdated treatment option of intranasal DDAVP.

DISCUSSION

These findings are concordant with the increasing body of literature demonstrating that patient education materials are too difficult to read. Pediatric urologists should be aware of the readability and quality of available online content for common clinical presentations. They can ensure that institutional articles online are useful to patients by participating in the development and design of these materials.

CONCLUSION

We demonstrated that online articles that families encounter via a search engine query for bedwetting are written at a higher level than recommended and the majority are of 'fair' quality. There is much room for improvement for institutions to provide high quality, readable content that supports the needs of families seeking information on NE.

First-morning urine osmolality and nocturnal enuresis in children: A single-center prospective cohort study

PURPOSE

To investigate the treatment outcome of nocturnal enuresis (NE) according to first-morning urine osmolality (Uosm) before treatment.

MATERIALS AND METHODS

Ninety-nine children (mean age, 7.2±2.1 y) with NE were enrolled in this retrospective study and divided into two groups according to first-morning Uosm results, that is, into a low Uosm group (<800 mOsm/L; 38 cases, 38.4%) or a high Uosm group (≥800 mOsm/L; 61 cases, 61.6%). Baseline parameters were obtained from frequency volume charts of at least 2 days, uroflowmetry, post-void residual volume, and a questionnaire for the presence of frequency, urgency, and urinary incontinence. Standard urotherapy and pharmacological treatment were administered initially in all cases. Enuresis frequency and response rates were analyzed at around 1 month and 3 months after treatment initiation.

RESULTS

The level of first-morning Uosm was 997.1±119.6 mOsm/L in high Uosm group and 600.9±155.9 mOsm/L in low Uosm group (p<0.001), and first-morning voided volume (p=0.021) and total voided volume (p=0.019) were significantly greater in the low Uosm group. Furthermore, a significantly higher percentage of children in the low Uosm group had a response rate of ≥50% (CR or PR) at 1 month (50.0% vs. 24.6%; p=0.010) and 3 months (63.2% vs. 36.1%; p=0.009).

CONCLUSIONS

Treatment response rates are higher for children with NE with a lower first-morning Uosm.

[Functional (Nonorganic) Enuresis and Daytime Urinary Incontinence in Children and Adolescents: Clinical Guideline for Assessment and Treatment]

Functional (Nonorganic) Enuresis and Daytime Urinary Incontinence in Children and Adolescents: Clinical Guideline for Assessment and Treatment Abstract: Objective: Enuresis and daytime urinary incontinence are common disorders in children and adolescents and are associated with incapacitation and a high rate of comorbid psychological disorders. This interdisciplinary guideline summarizes the current state of knowledge regarding somatic and psychiatric assessment and treatment. We formulate consensus-based, practical recommendations. Methods: The members of this guideline commission consisted of 18 professional associations. The guideline results from current literature searches, several online surveys, and consensus conferences based on standard procedures. Results: According to the International Children's Continence Society (ICCS), there are four different subtypes of nocturnal enuresis and nine subtypes of daytime urinary incontinence. Organic factors first have to be excluded. Clinical and noninvasive assessment is sufficient in most cases. Standard urotherapy is the mainstay of treatment. If indicated, one can add specific urotherapy and pharmacotherapy. Medication can be useful, especially in enuresis and urge incontinence. Psychological and somatic comorbid disorders must also be addressed. Conclusions: The recommendations of this guideline were passed with a high consensus. Interdisciplinary cooperation is especially important, as somatic factors and comorbid psychological disorders and symptoms need to be considered. More research is required especially regarding functional (nonorganic) daytime urinary incontinence.

Alarm-assisted urotherapy for daytime urinary incontinence in children: A meta-analysis

OBJECTIVES

Wearable alarm systems are frequently used tools added to urotherapy for children with both daytime and nighttime urinary incontinence. For functional daytime incontinence (DUI) specifically, the effect of alarm interventions has not been systematically reviewed. This study systematically evaluates, summarizes, reviews, and analyzes existing evidence about the effect of wearable alarm systems in urotherapy for children with functional DUI.

STUDY DESIGN

We completed a comprehensive literature search in August 2022 using MEDLINE/PUBMED, EMBASE, PsycINFO, Cochrane Library, Web of Science, Google Scholar, conference abstracts, and citation tracking. Clinical controlled trials at controlled-trials.com and clinicaltrials.gov were consulted, as was the National health Service Center For Reviews And Dissemination. Eligible studies including the use of noninvasive wearable alarm systems as (part of) treatment for functional DUI in children were included. The main outcome was continence after treatment. Three independent reviewers extracted data. Risk of bias was assessed using Cochrane and National Heart, Lung and Blood Institute quality assessment tools.

RESULTS

A total of 10 studies out of 1,382 records were included. Meta-analysis revealed a nonsignificant risk ratio of 1.4 (95% CI: 0.8-2.6) for the use of alarm systems. Urotherapy with alarm systems resulted in a 48% (95% CI: 33-62%) continence rate after treatment.

CONCLUSIONS

Alarm systems might be helpful as part of urotherapy for functional DUI in select cases. Adherence is problematic, and the optimal duration of the use of alarm systems is to be determined. Overall, the risk of bias was high in all studies.

Examination of posture and balance in children with primary monosymptomatic nocturnal enuresis

PURPOSE

This study aimed to examine symptom severity, posture, and balance of children with primary monosymptomatic nocturnal enuresis (PMNE) and compare to a healthy control group.

METHODS

Thirty-five children with PMNE and 34 healthy children were included in this study. Physical and sociodemographic characteristics of the children were recorded. Symptom severity was assessed with a Vancouver Non-Neurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire (NLUTD/DES), a four-day bladder diary and a seven-day bowel diary. Standing postural alignment was assessed with the Spinal Mouse device, and the sensory integration of static balance and dynamic standing balance was assessed with the Biodex Balance System SD.

RESULTS

Compared to healthy controls, children with PMNE demonstrated increased symptom severity (p = 0.001), increased upright lumbar lordosis (p = 0.018) and sacral-hip angles (p = 0.029), decreased static balance in the sensory condition of unstable surface with eyes closed (p = 0.001), and decreased mediolateral dynamic balance (p = 0.049).

CONCLUSION

Children with PMNE demonstrate altered postural alignment, static and dynamic postural instability, and greater symptom severity on the Vancouver NLUTD/DES than age-matched controls.

Daytime urotherapy in nocturnal enuresis: a randomised, controlled trial

OBJECTIVE

According to international guidelines, children with enuresis are recommended urotherapy, or basic bladder advice, before treatment with evidence-based alternatives such as the enuresis alarm is given. The efficacy of this strategy has, however, not been supported by controlled studies. We wanted to test if basic bladder advice is useful in enuresis.

DESIGN

Randomised, controlled trial.

SETTING

Paediatric outpatient ward, regional hospital.

PATIENTS

Treatment-naïve enuretic children aged ≥6 years, with no daytime incontinence.

INTERVENTIONS

Three groups, each during 8 weeks: (A) basic bladder advice-that is, voiding and drinking according to a strict schedule and instructions regarding toilet posture, (B) enuresis alarm therapy and (C) no treatment (control group).

MAIN OUTCOME MEASURES

Reduction in enuresis frequency during week 7-8 compared with baseline.

RESULTS

The median number of wet nights out of 14 before and at the end of treatment were in group A (n=20) 12.5 and 11.5 (p=0.44), in group B (n=22) 11.0 and 3.5 (p<0.001) and in group C (n=18) 12.5 and 12.0 (p=0.55). The difference in reduction of enuresis frequency between the groups was highly significant (p=0.002), but no difference was found between basic bladder advice and controls.

CONCLUSIONS

Urotherapy, or basic bladder advice, is ineffective as a first-line treatment of nocturnal enuresis. Enuretic children who are old enough to be bothered by their condition should be offered treatment with the alarm or desmopressin.

TRIAL REGISTRATION NUMBER

Impact of New vs. Old International Children's Continence Society Standardization on the Classification of Treatment Naïve Enuresis Children at Screening: The Value of Voiding Diaries and Questionnaires

Expert consensus papers recommend differentiating enuresis using questionnaires and voiding diaries into non- (NMNE) and monosymptomatic enuresis (MNE) is crucial at intake to decide the most appropriate workout and treatment. This national, Belgian, prospective study investigates the correlation, consistency, and added value of the two methods, the new against the old International Children's Continence Society (ICCS) definitions, and documents the prevalence of the two enuresis subtypes in our population. Ninety treatment-naïve enuretic children were evaluated with the questionnaire, and the voiding diary and the two clinical management tools were compared. Almost 30% of the children had a different diagnosis with each method, and we observed inconsistencies between them in registering Lower Tract Symptoms (κ = -0.057-0.432 depending on the symptom). Both methods had a high correlation in identifying MNE (rs = 0.612, p = 0.001) but not for NMNE (rs = 0.127, p = 0.248). According to the latest ICCS definitions, the incidence of MNE was significantly lower (7 vs. 48%) with the old standardization.

Conclusion

The voiding diary and the questionnaire, as recommended by the ICCS at the screening of treatment-naïve enuretic patients, are considerably inconsistent and have significantly different sensitivities in identifying LUTS and thus differentiating MNE from NMNE. However, the high incidence of LUTS and very low prevalence of MNE suggest that differentiating MNE from NMNE to the maximum might not always correlate with different therapy responses.

Problems with enuresis management-A personal view

Much has happened since the end of the era when enuresis was blamed on the parents or the children themselves. Still, there are large gaps in our knowledge and large parts of modern enuresis management guidelines are (still) not based on firm evidence. In this review I will question the following commonly made assumptions regarding enuresis evaluation and treatment: •It is important to subdivide enuresis according to the presence of daytime symptoms•Voiding charts are crucial in the primary evaluation of the enuretic child•All children with enuresis need to be screened for behavioral or psychiatric issues•Concomittant daytime incontinence needs to be successfully treated before addressing the enuresis•Concomittant constipation needs to be successfully treated before addressing the enuresis•Urotherapy is a first-line treatment against enuresis In this review I will argue that much of what we do with these children is based more on experience and well-meant but poorly supported assumptions than on evidence. Some advice and therapies are probably ineffective whereas for other treatments we lack reliable predictors of treatment response. More research is obviously needed, but awaiting new results enuresis management could be substantially simplified.

Conservative management of anterior located anus: A medium-long term follow up

BACKGROUND/PURPOSE

The anterior anus (AA) is a condition, almost exclusively present in females, in which the anus is located abnormally anterior along the perineal body, well separated from the vulva. Definition and treatment are still controversial. This study aimed to evaluate the medium-long term follow up of patients with AA conservatively managed, considering the gynaecologic aspects in post-menarchal girls.

MATHERIALS/METHODS

This cross-sectional study includes AA patients older than 3 years at time of the study, followed in two referral centres for ARM between January 2000 and May 2017. The API (Anal Position Index) was applied to define AA. A questionnaire regarding the ano-rectal function, occurrence of urinary infection (UTI), familiarity for ARM/AA was administered to parents and patients. Gynecological examination was performed in post-menarchal patients.

RESULTS

Fifty-three patients (all females) were retrieved. Three were excluded (2 underwent surgery at another center, 1 was lost at follow-up), 7/50 had major malformations (2 oesophageal atresia, 4 cardiovascular malformations and 1 with Fallot, uretheral duplicity and vertebral anomalies), 5/50 had familiarity for ARM/AA. Only 10% were constipated. Fifteen patients underwent gynecological examination. Their mean API was 0.278 +/- 0.013 DS, they had good buttock tropism, normal resident bacteria, and no UTI.

CONCLUSION

AA patients in our centers do not undergo any kind of surgery. At least three quarters of them have a perfectly normal bowel habits and adolescents do not present symptoms related to their condition. These results support the conservative management of this condition.

Treating enuresis in children with neurodevelopmental disorders using bell and pad alarm

OBJECTIVE

There is a high prevalence of enuresis in children with neurodevelopmental disorders, yet research regarding treatment for this group has been neglected. The efficacy of treatment using bell and pad alarm therapy is not well reported especially in children with neurodevelopmental disorders. This study sought to compare the treatment efficacy of practitioner-assisted bell-and-pad enuresis alarm therapy for children with neurodevelopmental disorders and typically developing children.

STUDY DESIGN

This study utilized the data of Apos et al. (2018), a retrospective medical record audit collected from multiple clinical settings across Australia. A total of 2986 patient records (3659 treatment records) were included. The participants were children aged 5-16 years, who were diagnosed with enuresis. Children with a neurodevelopmental disorder (n = 158) had a clinical diagnosis present in the medical history of attention deficit disorder, autism spectrum disorder, or intellectual disability. Children who indicated any of the following comorbidities were excluded: cerebral palsy, brain injury, malformation of the renal tract, previous bladder or renal surgery, spinal cord malformation, spinal cord trauma or tumor, or a neurodegenerative disorder. Treatment success was defined as ≥ 14 dry nights. Relapse was defined as one symptom recurrence per month post-interruption of treatment, as defined by the International Children's Continence Society definitions.

RESULTS

The success rate for children with neurodevelopmental disorders was 62% and typically developing children was 78%. There was no significant difference between the number of treatments received or relapse rates by those children with a neurodevelopmental disorder and typically developing children. The summary figure shows the percentage of children in each group after their first treatment who were successful (success defined as dry for ≥ 14 days), who succeeded (dry for ≥ 14 days) but then relapsed and those who showed no success. The percentage of children with no NDD who were successfully dry after the first treatment was 78%. Children with ID had success after the first treatment of 59%, the lowest of all groups analyzed.

CONCLUSION

The type of alarm therapy reported in this study is effective for treating enuresis in children with neurodevelopmental disorders.

Outcome of a thorough screening of lower urinary tract function in all pediatric kidney recipients

LUTD is one of the possible factors influencing pediatric kidney graft outcomes. This study evaluates the results of a thorough assessment of voiding behavior in pediatric transplants. Data of patients with kidney disease of nephrological origin are compared to those with urological origin. A single-center analysis of pediatric kidney transplants performed from 2005 to the present was executed. Donor and recipient characteristics as well as voiding and drinking habits were documented using FVCs and uroflowmetry with PVR measurements. LUTD was defined by a mean MVV >150% or <65% of the EBC for age, abnormal uroflowmetry, PVR repeatedly >15% of EBC or >20 mL, abnormal voiding patterns or behavior, and presence of LUT symptoms. LUTD was diagnosed in 71% of the 56 screened children and more present in urological origin of kidney disease (100%) compared to nephrological origin (61%, P = .005). Individual presence of LUT symptoms, abnormal voiding behavior, FVC parameters, UTIs, and uroflowmetry/PVR parameters were not different between the two groups. Polyuria after transplantation was seen in 63% of patients, mainly in the first post-transplant years and recipients aged <10 years. Time after transplantation was a significant independent predictive factor for the presence of LUTD. LUTD is common in all pediatric kidney recipients and underestimated in those with a nephrological origin of disease. Active screening, monitoring and a care attention plan prior to transplantation and during follow-up, is advocated to optimize outcomes for all patients.

Definitions, indications and practice of urotherapy in children and adolescents: - A standardization document of the International Children's Continence Society (ICCS)

BACKGROUND

Urotherapy is an umbrella term for all non-surgical, non-pharmacological interventions for lower urinary tract disorders (LUTD) in children and adolescents. Urotherapy is a specialized practice, which has become mainstay therapy not only for daytime urinary incontinence, but also for nocturnal enuresis, functional constipation and fecal incontinence. The aim of urotherapy is to achieve the normalization of the micturition and bowel pattern and to prevent further functional disturbances by repeated training. It is well known that in the treatment of adult and childhood incontinence a team approach is best, where there are shared areas of expertise and also discipline-specific expertise available.

AIM

We present a consensus view from a cross-professional team of experts affiliated with the International Children's Continence Society on definitions, indications and practice of urotherapy. This is a selective, non-systematic review with practical recommendations for the implementation and research on urotherapy.

METHODS

The document uses the globally accepted ICCS terminology. Evidence-based literature serves as the basis, but in areas lacking in primary evidence, expert consensus is used. Before submission, a full draft was made available to all ICCS members for additional comments.

RESULTS

Urotherapy uses non-pharmacological, non-surgical methods and focuses on behavioral interventions, largely based on cognitive-behavioral psychotherapy (CBT). Standard urotherapy comprises components such as provision of information, instructions, life-style advice, counselling and registration of symptoms. Specific urotherapy is tailored towards specific disorders and includes alarm treatment, biofeedback training, pelvic floor training, neurostimulation and other interventions. Fig. 1. Urotherapy is a treatment that addresses all aspects of incontinence, leading to the best clinical outcome. This includes somatic, psychosocial, and behavioral problems and quality of life. Therefore urotherapy is recommended by the ICCS as the first-line treatment for most types of LUTD. The document is intended to be clinically useful in primary, secondary and tertiary care.

Endoscopic Botulinum Toxin Injection for Refractory Enuresis Based on Urodynamic Assessment

Purpose

This study aimed to determine the urodynamic characteristics of refractory enuresis and explored whether those characteristics can be managed through differential endoscopic injections with botulinum toxin.

Methods

In total, 27 patients with nonmonosymptomatic enuresis who showed no response after conservative treatment for more than 12 months were included. The patients then underwent a videourodynamic study and received a differential endoscopic injection of botulinum toxin on the same day. Reduced capacity, detrusor overactivity, and bladder neck widening were the 3 major abnormal findings assessed during the filling phase, while sphincter hyperactivity was the only abnormality assessed during the emptying phase. An intravesical or intrasphincteric injection of botulinum toxin was attempted according to the videourodynamic study findings. Follow-up was conducted at 1, 3, 6, and 12 months after treatment.

Results

The median age was 10 years (range, 7–31 years). Although 19 and 8 patients had a preoperative diagnosis of overactive bladder or dysfunctional voiding, respectively, the urodynamic diagnosis was different in more than half of the patients. Those showing detrusor overactivity benefited from intravesical botulinum toxin injection, whereas those with only sphincter hyperactivity benefited from both intravesical and intrasphincteric injections. Treatment resistance to botulinum toxin seemed to be attributable to bladder neck widening. Time had no apparent effect on efficacy, which persisted 6 months after the injection. More than 80% of the patients maintained the benefits of the injection after 1 year.

Conclusions

Videourodynamic studies were useful for identifying the reasons underlying refractory nonmonosymptomatic enuresis and helpful for determining the appropriate site of botulinum toxin injection.

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.

A comparison of the efficacy and tolerability of treating primary nocturnal enuresis with Solifenacin Plus Desmopressin, Tolterodine Plus Desmopressin, and Desmopressin alone: a randomized controlled clinical trial

INTRODUCTION

Nocturnal enuresis (enuresis) is one of the most common developmental problems of childhood, which has often a familial basis, causes mental and psychological damage to the child and disrupts family solace.

OBJECTIVES

In this study, we compared therapeutic efficacy and tolerability of treating primary nocturnal enuresis (PNE) with solifenacin plus desmopressin, tolterodine plus desmopressin, and desmopressin alone. Because we don't have enough information about this comparison especially about solifenacin plus desmopressin.

PATIENTS AND METHODS

This clinical trial study was performed on 62 patients with enuresis aged 5-15 years who referred to the urology clinic of Imam Khomeini Hospital in Ahwaz in 2017-2018. Patients were randomly assigned to one of the three different therapeutic protocols and any participants were given a specific code. After that, we compared the therapeutic response and the level of satisfaction of each therapeutic group in different months. Data were analyzed using SPSS 22 software and descriptive and analytical statistics.

RESULTS

The mean age of patients was 8.70±66 years. In the therapeutic group with desmopressin and solifenacin, 19 of 20 patients (95%) achieved complete remission (1) after a 3-month treatment in comparison with monotherapy group in which 14 of 22 patients (63.63%) achieved complete remission; and in the combination therapy group of desmopressin and tolterodine, in the study and the evaluation of the consequences of 3-month treatment of this group, it was found that 17 of 20 patients (85%) had complete remission. Overall, the therapeutic response in combination therapy groups of desmopressin plus anticholinergic was higher than the monotherapy group of desmopressin alone.

CONCLUSION

Our results demonstrate that the combination of desmopressin and an anticholinergic agent is highly effective in treatment of children with PMNE. Although desmopressin has long been a first - line treatment for PMNE, desmopressin monotherapy often fails to achieve a successful response in patients with PMNE.

Uroflowmetry in Non-Monosymptomatic Nocturnal Enuresis in Children of Coastal Region of Croatia

PURPOSE

The aim of the study was to describe clinical characteristics and bladder assessment in children with Non-Monosymptomatic Nocturnal Enuresis (NMNE) in coastal region of Croatia.

MATERIALS AND METHODS

Records on 85 patients with NMNE were retrospectively reviewed. Bladder assessments were performed in all children. In this research we: (i) compare clinical characteristics and features of bladder assessment: uroflowmetry, post void residuals (PVR) and bladder wall thickness between boys and girls with NMNE and we compare (ii) clinical characteristics and bladder assessment between children with primary and secondary NMNE.

RESULTS

There were 46 girls and 39 boys. The total of 59 children had primary NMNE and 26 children had secondary NMNE. Uroflow pattern was abnormal in 42% of all children with NMNE. Abnormal uroflow pattern in children with NMNE was more often in girls than in boys (P < 0.05) and in children with secondary than in children with primary NMNE (P < 0.05). Ultrasound evidence of bladder wall thickness was more frequent in boys than in girls. Girls were more likely to have dysfunctional voiding and larger residual urinary volume than boys.

CONCLUSIONS

Abnormal uroflow pattern in children with NMNE was more often in girls than boys and in children with secondary than in children with primary NMNE.

Accuracy and comprehensiveness of publicly-available online data about bedwetting: An actionable opportunity to improve parent and caregiver self-education

INTRODUCTION

Monosymptomatic nocturnal enuresis (MNE) is one of the most common reasons for referral to pediatric urologists. Prior to subspecialist visits, many parents seek electronically available information online to gather information about this condition and potential treatment options. Previous publications suggest that electronically available information on medical conditions do not always align with evidence-based or expert recommendations. We wondered if the same was true for MNE.

OBJECTIVE

To describe the content and accessibility of electronically available information on MNE, and its alignment with recommendations from the International Children's Continence Society (ICCS-MNE).

STUDY DESIGN

We simulated a layperson's electronic search using 10 pertinent search terms associated with bedwetting. We evaluated the first five pages (50 results) for each search. We evaluated all publicly-available (non-paywalled) sites for concordance with ICCS-MNE in eight domains (increasing fluid intake, limiting bladder irritants, optimizing bowel habits, utilizing timed voiding, pelvic floor relaxation, endorsing alarm use, avoiding medications as standard first-line therapies, and pediatrician referral), as well as statements discouraging blaming or punishing the child. Sites were classified as layperson-derived (blogs, communities/forums) or commercially-derived (medical institutions, commercial medical sites, corporations, government). Reading level was assessed by readable.io (compound scoring algorithms).

RESULTS

Of 500 pages, 410 (82%) met inclusion criteria. Of these, 49.3% were layperson-derived and 47.8% were commercially-derived. Publication year ranged from 1999 to 2017. A median three (range 0-8) therapeutic domains were mentioned per site. Only one site discussed all eight therapeutic domains. Commercial sites discussed more ICCS-MNE domains than blogs and communities/forums (median 4.1 vs. 2.4, p < 0.0001; Figure). Blogs and forums were less likely to recommend subspecialist evaluation (53.0% vs. 81.1%, p < 0.0001), but more likely to recommend alternative medicine therapies (57.9% vs. 28.6%, p < 0.0001). The overall median readability grade level was lower for blogs/communities than for commercial sites (7.9 vs. 8.6, p < 0.0001).

DISCUSSION

Our findings show that the vast majority of electronically available information on MNE is not congruent with or does not include all ICCS-MNE recommendations. About half of websites are blogs and forums; these not only are more likely to recommend alternative medicine therapies and less likely to recommend subspecialist evaluation, but have lower reading levels and thus may be accessible to more laypersons.

CONCLUSION

Neither commercially-derived nor layperson-derived websites are comprehensive with regard to ICCS-MNE recommendations. Our findings underscore the need to ensure that electronically published data are accurate, and to understand what data patients may have acquired before visiting with clinicians.

Evaluation of Functional Bladder Capacity in Children with Nocturnal Enuresis According to Type and Treatment Outcome

Purpose

This study aimed to identify whether functional bladder capacity (FBC) differs among subgroups of nocturnal enuresis (NE) patients and can be used to predict treatment response.

Methods

A total of 69 children with NE were included in this study between July 2017 and February 2019 according to medical chart review, retrospectively. All patients completed a questionnaire about voiding symptoms and 48-hour frequency/volume (48-h F/V) charts. FBC was obtained from the 48-h F/V charts and uroflowmetry (UFM) with post-void residual volume (PVR). All patients were primarily treated with standard urotherapy and pharmacological therapy. The response rate was analyzed at 3 months after treatment.

Results

The mean age of the 69 patients (42 male, 27 female) was 83.3 ± 22.4 months (range, 5–13 years) at the first visit. The percentages of children with monosymptomatic NE (MNE) and non-monosymptomatic NE (NMNE) on the questionnaire were 40.6% (28/69) and 59.4% (41/69), respectively. FBC of all patients was lower than the normal range of expected bladder capacity, and there were no significant differences between measurement methods, NE types (MNE vs NMNE), or response rates (p > 0.05).

Conclusion

Children with NE had diminished FBC in both 48-h F/V charts and UFM with PVR. We found no difference in FBC by NE type or treatment outcome. Therefore, FBC cannot be used to distinguish between NE types or predict treatment responses.

Patient Engagement in Medical Device Design: Refining the Essential Attributes of a Wearable, Pre-Void, Ultrasound Alarm for Nocturnal Enuresis

BACKGROUND

To date, no pre-void wearable alarm exists to treat nocturnal enuresis (NE)-night-time bedwetting, and children with NE and their families are disappointed in relation to the post-void moisture alarms and medicine currently available. Development of a safe, comfortable and non-invasive wearable pre-void alarm and associated technology, using advanced mechatronics, is underway (the MyPAD device). Each stage of development includes patient and public involvement (PPI), particularly with respect to human factors, in collaboration with physicians, radiologists, psychologists, nurses, engineers and designers.

OBJECTIVES

The aim of this study was to help us understand the families' experience of the condition of enuresis, and to provide opinion relating to existing NE alarms, designed to detect moisture, and most importantly, the initial design of the MyPAD wearable technology.

METHODS

A PPI workshop in the form of a focus group, made up of children with enuresis and their parents, was conducted during the early stage of the MyPAD product development. The key research questions (RQs) were: (RQ1) What were the families' experiences of using existing post-void enuresis alarms? (RQ2) What do families like about the MyPAD prototype? and (RQ3) What do families not like about the MyPAD prototype? A nurse specialised in terms of NE treatment, including post-void alarms, from the Lancashire Teaching Hospitals NHS Foundation Trust, and two MyPAD design engineers were also present, to explain the MyPAD design concept. Braun and Clarke's six-phase approach to thematic analysis was implemented, which included familiarisation with the data, initial descriptive coding, identifying themes, reviewing themes, defining and labelling themes and producing a report.

RESULTS

Four common themes were identified from the focus group discussions: the importance of sleep; children do not want to feel different; parents feel frustrated and concerned; resilience and perseverance. These themes applied across the research questions; for example, sleep disruption was highlighted as an issue with existing post-void alarms and as an important requirement for the design of MyPAD. The evaluation of the early version of the MyPAD device has prompted the consideration of changes to some existing facets of the device, including providing multiple alarm types, more options for the design of the garment that houses the device, and the need for clear, age-appropriate and informative instructions relating to how the device should be used, in order to maximise its performance/efficiency and acceptance.

CONCLUSIONS

The qualitative data derived from the focus group discussion was incredibly valuable as it enabled the research and design team to experience the perspectives of the families in terms of the challenges and conflicts of managing the condition and the limited utility of existing post-void alarms. This has improved our understanding of the social and environmental challenges that will need to be considered during the design process.

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

AIMS

Children with nocturnal enuresis (NE), daytime urinary incontinence (DUI), and fecal incontinence (FI) are at risk for behavioral problems, overweight, and obesity. The aim of this study was to analyze the specific behavioral and weight comorbidity in subtypes of incontinence.

METHODS

A total of 1638 consecutive patients presented to a tertiary incontinence clinic from 2012 to 2018 was examined prospectively according to ICCS criteria. Behavioral symptoms were measured with the Child Behavior Checklist (CBCL). Psychiatric disorders were diagnosed according to ICD-10 criteria. Weight categories were calculated according to WHO recommendations.

RESULTS

The mean age was 7.8 years, 67% of patients were male. Fifty-seven percent had NE (n = 934), 33% DUI (n = 547), and 40% FI (n = 656). Boys had significantly higher rates of NE and FI than girls. Of all children, 39.2% (n = 539) had a clinically relevant CBCL total score. A total of 28.3% (n = 463) had an ICD-10 psychiatric diagnosis, mainly ODD and ADHD, and 28.6% (n = 463) were overweight or obese. Boys were more often affected by behavioral symptoms, psychiatric disorders, and overweight/obesity. Children with NE had the highest rate of overweight/obesity. Except for primary nonmonosymptomatic NE, subtypes of incontinence did not differ regarding behavioral symptoms and weight categories. However, overweight/obesity was significantly associated with behavioral and psychiatric parameters.

CONCLUSIONS

Behavioral symptoms and psychiatric disorders, as well as overweight/obesity are important risk factors associated with incontinence, but the interaction between these factors is complex. In clinical settings, all children with incontinence should be screened with behavioral questionnaires. Also, weight should be measured, and overweight/obesity should be addressed.

The prognostic value of voiding chart data in therapy-resistant enuresis

INTRODUCTION

The case history is the primary tool when investigating the enuretic child. To further determine whether nocturnal polyuria or detrusor overactivity is present, a full voiding chart, is the method of choice. However, there is no robust evidence that daytime voiding chart data actually do predict nocturnal detrusor function.

AIM

The aim of this study was to assess the predictive value of anamnestic data and the voiding chart in the treatment of children with therapy-resistant enuresis.

PATIENTS AND METHODS

The patients all suffered from enuresis resistant to first-line therapy. None of the children had daytime incontinence. In accordance with international recommendations, the children were first treated with anticholinergics. If the therapeutic effect was not satisfactory dosage was adjusted and desmopressin was added. If sufficient treatment effect was not achieved, antidepressant therapy was tried next, combined with desmopressin if needed. Since this was an evaluation of clinical practice, not a randomized trial, treatment success was graded according to family satisfaction, not the actual frequency of wet nights. Thus, only children who reported that they were completely dry were regarded as full responders and those who stated that there was a substantial and useful reduction of wet nights were labeled intermediate responders.

RESULTS

In total, 154 patients were included. Few and inconsistent differences were found between the groups responding or not responding to the various treatment regimens, and this was true both for anamnestic and voiding chart data (see Table). The only statistically significant findings were that responders to antidepressant therapy were older (p = 0.013) than non-responders, and patients who benefited from addition of desmopressin had a higher micturition frequency than those who did not (p = 0.027). The children who needed desmopressin as part of combination treatment to become dry did not have significantly higher nocturnal urine production than those who had no such benefit (p = 0.619). Neither the presence of urgency nor a history of previous daytime incontinence was significantly more common in children responding to anticholinergics (p = 0.375 and 0.072, respectively).

DISCUSSION

No clear and consistent differences in either anamnestic factors or voiding chart data were found between the patients responding or not responding to the various treatment regimens. Not even urgency could predict anticholinergic efficacy. Somewhat surprisingly, no association between nocturnal polyuria and desmopressin benefit was found.

CONCLUSION

In this study no prognostic value was found in anamnestic or voiding chart data in children with therapy resistant enuresis.

Abnormal Thalamic Functional Connectivity During Light Non-Rapid Eye Movement Sleep in Children With Primary Nocturnal Enuresis

OBJECTIVE

To investigate abnormalities of thalamocortical and intrathalamic functional connectivity (FC) in children with primary nocturnal enuresis (PNE) during light non-rapid eye movement (NREM) sleep using a simultaneous electroencephalography (EEG)-functional magnetic resonance imaging (fMRI) method.

METHOD

Polysomnographic and EEG-fMRI data were obtained during sleep from 61 children with PNE (age 10.2 ± 1.7 years, 59% boys) and 61 age-matched controls (age 10.1 ± 1.4 years, 54% boys). All subjects first participated in one overnight video-polysomnographic study. Total sleep time, percentage of total sleep time in each sleep stage, arousal index, and awakening index were calculated. Simultaneous EEG-fMRI studies were then performed using a 3T MRI system with a 32-channel MRI-compatible EEG system. Visual scoring of EEG data permitted sleep staging. Thalamocortical and intrathalamic FCs in the waking state and at different stages of light sleep were calculated and compared.

RESULTS

Children with PNE had a higher percentage of total sleep time in light sleep and a higher arousal index compared with controls. Abnormal thalamocortical FCs were detected in the lateral prefrontal cortex, medial prefrontal cortex, and inferior parietal lobule during light NREM sleep. Abnormal intrathalamic FCs were also detected during light NREM sleep among the motor, occipital, prefrontal, and temporal subdivisions of the thalamus.

CONCLUSION

Abnormal prefrontal and parietal thalamocortical FCs, accompanied by abnormal intrathalamic FCs among the motor, occipital, prefrontal, and temporal subdivision of thalamus during light NREM sleep, may be related to abnormal sleep and enuresis in children with PNE.

Management and treatment of nocturnal enuresis-an updated standardization document from the International Children's Continence Society

BACKGROUND

Enuresis is an extremely common condition, which, although somatically benign, poses long-term psychosocial risks if untreated. There are still many misconceptions regarding the proper management of these children.

AIM

A cross-professional team of experts affiliated with the International Children's Continence Society (ICCS) undertook to update the previous guidelines for the evaluation and treatment of children with enuresis.

METHODS

The document used the globally accepted ICCS terminology. Evidence-based literature served as the basis, but in areas lacking in primary evidence, expert consensus was used. Before submission, a full draft was made available to all ICCS members for additional comments.

RESULTS

The enuretic child does, in the absence of certain warning signs (i.e., voiding difficulties, excessive thirst), not need blood tests, radiology or urodynamic assessment. Active therapy is recommended from the age of 6 years. The most important comorbid conditions to take into account are psychiatric disorders, constipation, urinary tract infections and snoring or sleep apneas. Constipation and daytime incontinence, if present, should be treated. In nonmonosymptomatic enuresis, it is recommended that basic advice regarding voiding and drinking habits be provided. In monosymptomatic enuresis, or if the above strategy did not make the child dry, the first-line treatment modalities are desmopressin or the enuresis alarm. If both these therapies fail alone or in combination, anticholinergic treatment is a possible next step. If the child is unresponsive to initial therapy, antidepressant treatment may be considered by the expert. Children with concomitant sleep disordered breathing may become dry if the airway obstruction is removed.

"Posterior Tibial Nerve" or "Tibial Nerve"? Improving the reporting in health papers

AIMS

The primary objective of this study is to identify which term is the most appropriate to use according to anatomical nomenclature: "posterior tibial nerve" or "tibial nerve." Furthermore, this paper intends to show how the use of these terms in papers indexed in important health databases is numerous and to describe the anatomical characteristics of such nerve, to improve future scientific publications.

METHODS

This is a descriptive study about the importance of standardizing the use of the terms "posterior tibial nerve" and "tibial nerve" and its anatomy. It comprises three phases: the first is a search in the main databases to identify the use of the terms "posterior tibial nerve" and "tibial nerve." The second phase refers to the consultation of international anatomical terminology to identify the most appropriate term to refer to the nerve, while the third phase is related to the study of the anatomy of this nerve.

RESULTS

The term "tibial nerve" is more commonly used, but the use of the term "posterior tibial nerve" is still very substantial. According to international anatomical terminology, the correct term is "tibial nerve," which is a branch of the sciatic nerve.

CONCLUSIONS

"Tibial nerve" is the term standardized by international anatomical terminology. The use of terms in accordance with Terminologia Anatomica is important to facilitate the process of teaching and learning, as well as to improve the reporting and interpretation of papers regarding health, and the evidence-based clinical practice.

Brazilian consensus in enuresis-recomendations for clinical practice

Introduction

Enuresis, defined as an intermittent urinary incontinence that occurs during sleep, is a frequent condition, occurring in about 10% of children at 7 years of age. However, it is frequently neglected by the family and by the primary care provider, leaving many of those children without treatment. Despite of many studies in Enuresis and recent advances in scientific and technological knowledge there is still considerable heterogeneity in evaluation methods and therapeutic approaches.

Materials and Methods

The board of Pediatric Urology of the Brazilian Society of Urology joined a group of experts and reviewed all important issues on Enuresis and elaborated a draft of the document. On September 2018 the panel met to review, discuss and write a consensus document.

Results and Discussion

Enuresis is a multifactorial disease that can lead to a diversity of problems for the child and family. Children presenting with Enuresis require careful evaluation and treatment to avoid future psychological and behavioral problems. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.

Pharmacologic therapies for the management of non-neurogenic urinary incontinence in children

Introduction: Non-neurogenic urinary incontinence in children is a common condition that affects the quality of life for both patients and parents. Symptoms may occur in the daytime, nighttime, or both and may be the result of structural and functional anomalies. Evaluation and management of associated co-morbidities, such as constipation is critical to management. Behavioral therapy is a fist line therapy in most cases of non-neurogenic urinary incontinence and pharmacologic therapy a second-line therapy.Areas covered: In this review, the authors cover the pharmacologic agents, FDA approved and commonly used non-FDA approved, available for the treatment of four non-structural etiologies of non-neurogenic urinary incontinence in children. These include nocturnal enuresis, overactive bladder, giggle incontinence, and dysfunctional voiding.Expert opinion: Non-neurogenic causes of urinary incontinence in children represent a complicated medical condition that requires both pharmacologic and non-pharmacologic management. Limited FDA-approved therapies as well as suboptimal results with approved therapies due to a lack in the understanding of the underlying pathophysiology and patient selection may lead to the use of alternative non-FDA approved therapies.

A novel method of rapid appraisal of clinical practice guidelines for children with enuresis

BACKGROUND

Enuresis (bedwetting) is a common but variably managed pediatric condition. Despite an abundance of published documents which provide recommendations for clinical evaluation and management of enuresis, no formal appraisal of their methodological quality has been undertaken.

OBJECTIVE

The objective of the study is to evaluate the quality of current pediatric guidelines for enuresis (bedwetting) using a novel method of appraisal.

STUDY DESIGN

A comprehensive gray literature search was undertaken to identify guideline documents that provided recommendations for management of enuresis in children and adolescents. The search strategy included guideline databases, targeted websites, Google search engines, and MEDLINE. Guideline documents included clinical practice guidelines, consensus documents, position statements, and other clinical review documents. Each document underwent basic appraisal by two independent assessors using the International Centre for Allied Health Evidence (iCAHE) Guideline Quality Checklist. Those documents which (1) had an iCAHE quality score of ≥10; (2) used a systematic search strategy; and (3) linked evidence to their recommendations underwent further detailed appraisal using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

RESULTS

Eighteen documents were shortlisted for basic appraisal. The iCAHE highlighted a lack of information regarding underlying evidence and dates (mean score 36% and 41%, respectively). Only three documents met basic quality criteria and progressed to detailed appraisal using the AGREE II. These included guidelines produced by the Paediatric Society of New Zealand and National Clinical Guideline Centre and a position statement from the Canadian Paediatric Society. All three guidelines presented clear and unambiguous recommendations (mean score 80%). However, information regarding stakeholder involvement was lacking (mean score 50%).

CONCLUSIONS

Several guidelines exist for the evaluation and management of children with enuresis, but many lack appropriate methodological quality standards. The guideline produced by the National Clinical Guideline Centre achieved the highest quality rating and is recommended for future adaptation and implementation in relevant clinical settings.

Pelvic floor muscle training alone or in combination with oxybutynin in treatment of nonmonosymptomatic enuresis. A randomized controlled trial with 2-year follow up

Objective

To compare the results of the standard urotherapy alone and associated with pelvic floor muscle training alone, and in combination with oxybutynin in treatment of nonmonosymptomatic nocturnal enuresis.

Methods

A total of 38 children aged 5 to 10 years were randomized into three groups: Group I (n=12) that was submitted to standard urotherapy; Group II (n=15), standard urotherapy associated with pelvic floor muscle training; and Group III (n=11), standard urotherapy associated with pelvic floor muscle training and oxybutynin; the treatment lasted 12 weeks. The assessment tools used were playful bladder diary, and a 48-hour bladder diary, before and after treatment. After 2 years, patients were assessed by telephone using a standardized questionnaire.

Results

The data of children from the three groups were homogeneous at baseline. After 12-week treatment, all children showed improved symptoms and signs of nonmonosymptomatic nocturnal enuresis, but the differences were not significant among the groups. After 2 years, the three groups showed maintenance of treatment results, but no differences among them.

Conclusion

All treatment modalities were effective regarding improved enuresis and lower urinary tract symptoms, but the sample was not large enough to show differences among groups.

The Diagnosis and Treatment of Enuresis and Functional Daytime Urinary Incontinence

BACKGROUND

Elimination disorders in childhood are common and treatable. Approximately 10% of 7-year-olds wet the bed at night, and 6% are affected by incontinence during the daytime. Two main types of disturbance are distinguished: nocturnal enuresis and functional (i.e., non-organic) daytime urinary incontinence. Each type contains a wide variety of subtypes. Effective treatment requires precise identification of the subtype of elimination disorder.

METHODS

This review is based on a selection of current publications, including principally the German S2k-AWMF guideline and the recommendations of the International Children's Continence Society (ICCS).

RESULTS

Diagnostic assessment focuses on the clinical picture, is non-invasive, and can be carried out in most health care settings. If the child is suffering from multiple types of elimination disorder at once, then fecal incontinence or constipation is treated first, daytime urinary incontinence next, and enuresis last. 20-50% of children with elimination disorders have a comorbid mental disorder that also needs to be treated. With standard urotherapy, 56% of patients with daytime urinary incontinence become dry within a year. This conservative, symptom-oriented approach consists of educating the patient and his or her parents to promote behavior changes with respect to drinking and micturition. Elements of specific urotherapy are provided only if indicated. For enuresis, the treatment of first choice is alarm therapy, with which 50-70% of the affected children become dry. Pharmacotherapy, e.g., with desmopressin, can be a helpful adjunctive treatment. In intractable cases, training techniques have been found useful.

CONCLUSION

Childhood elimination disorders can be treated effectively after targeted diagnostic evaluation and the establishment of specific indications for treatment. In view of the emotional distress these disorders cause, the associated physical and mental disturbances, and their potential persistence into adolescence, they should be evaluated and treated in affected children from the age of five years onward.

Use of propranolol in children with primary nocturnal enuresis

In nocturnal enuresis, motivational therapy, alarm therapy, and drug therapy, such as anticholinergics, imipramine, and sertraline, are the mainstay of treatment. In the present study, we used motivational therapy, oxybutynin, and propranolol in children with primary nocturnal enuresis to determine if propranolol is an effective treatment. Fifty-two children with primary nocturnal enuresis were included in the study. Firstly, motivational therapy was given for 1 month to all patients. Patients who failed the motivational therapy were randomly given oxybutynin or propranolol. The patients were re-evaluated after 1 month of drug therapy. There was not a significant difference between oxybutynin and propranolol groups for initial frequency of nocturnal enuresis ( p > 0.05). Of 52 patients, 28 (53.8%) patients improved by motivational therapy. There were 14 patients in the oxybutynin group. One patient was excluded from the study because facial flushing and mouth drying developed in the first week of oxybutynin therapy. In oxybutynin group, 12 of 13 (92.3%) patients improved. There were 10 patients in the propranolol group. In the propranolol group, while nine (90%) patients did not improve, one patient had significant remission (90%, p < 0.001). No significant adverse reaction was noted during propranolol therapy. There was no significant difference between oxybutynin and propranolol groups for initial frequency of nocturnal enuresis (p > 0.05). A significant difference was found between the groups for the remission of nocturnal enuresis ( p < 0.001). Our findings showed that motivational therapy is the first line treatment in primary nocturnal enuresis, and oxybutynin but not propranolol is effective in patients who failed with the motivational therapy.

The amount of urine voided in bed by children with enuresis

INTRODUCTION

Enuretic children wet their beds either because of nocturnal polyuria or nocturnal detrusor overactivity. Polyuric children often respond to desmopressin, whereas children with nocturnal detrusor overactivity are often therapy resistant and may have low daytime voided volumes. It is logical to assume that the enuretic event in children with nocturnal polyuria occurs with a full bladder, i.e. with the enuretic voided volume (EVV) close to the child's expected bladder capacity (EBC) for his/her age. However, the EVV has only rarely been studied, and little is known about how it relates to case history, polyuria, or daytime bladder function. The aim of this study was to look at EVV and relate it to voiding chart data and treatment response.

METHODS

Anamnestic data and voiding charts, including measurement of nocturnal urine production and EVV, in enuretic children with or without concomitant daytime incontinence attending a tertiary center were retrospectively reviewed. The EVV was analyzed and compared to anamnestic data, voiding chart data, and response to therapy in accordance with the guidelines of the International Children's Continence Society.

RESULTS

Data were available for 220 children (age 5-24, median 9), 40 of whom were girls. The prevalence of previous or present daytime incontinence was 42.4%, and 50.5% sometimes experienced urgency. The average EVV was 54.9 ± 32.8% of EBC. EVV correlated highly significantly to nocturnal urine production (p < 0.001). Still, EVV ≥ EBC was observed in only 16 children. EVV was slightly larger in girls (p = 0.013) and in children with urgency (p = 0.034), but there were no significant EVV differences between children responding or not responding to antidiuretic, anticholinergic, or antidepressant therapy. Relevant data are summarized in the Table below.

DISCUSSION

Case history and daytime voiding chart data give very little information about nocturnal bladder function. The EVV is strongly influenced by nocturnal urine production but only rarely reaches up to a level close to or exceeding the EBC. The enuretic event only very rarely represents the emptying of a full bladder. Thus, a component of nocturnal detrusor overactivity can be assumed to be present in almost all enuretic children, even in children with nocturnal polyuria. The value of the EVV is limited in predicting response to therapy.

International Continence Society (ICS) report on the terminology for nocturia and nocturnal lower urinary tract function

INTRODUCTION

The terminology for nocturia and nocturnal lower urinary tract function is reviewed and updated in a clinically and practically-based consensus report.

METHODS

This report has been created by a Working Group under the auspices and guidelines of the International Continence Society (ICS) Standardisation Steering Committee (SSC). All relevant definitions were updated on the basis of research over the last 16 years since the publication of the first nocturia standardization document in 2002. An extensive process of 16 rounds of internal and external reviews was involved to examine each definition exhaustively, with decision-making by collective opinion (consensus).

RESULTS

A clinically-based terminology report for nocturia and nocturnal lower urinary tract function, encompassing five key definitions divided into signs and symptoms has been developed. Clarity and user-friendliness have been key aims to make it interpretable by healthcare professionals and allied healthcare practitioners involved in the care of individuals with nocturnal lower urinary tract function.

CONCLUSION

A consensus-based terminology report for nocturia and nocturnal lower urinary tract function has been produced to aid clinical practice and research.

A prospective cohort study of biopsychosocial factors associated with childhood urinary incontinence

The objective of the study was to examine the association between biopsychosocial factors and developmental trajectories of childhood urinary incontinence (UI). We used developmental trajectories (latent classes) of childhood UI from 4-9 years including bedwetting alone, daytime wetting alone, delayed (daytime and nighttime) bladder control, and persistent (day and night) wetting (n = 8751, 4507 boys, 4244 girls). We examined whether biopsychosocial factors (developmental level, gestational age, birth weight, parental UI, temperament, behaviour/emotional problems, stressful events, maternal depression, age at initiation of toilet training, constipation) are associated with the trajectories using multinomial logistic regression (reference category = normative development of bladder control). Maternal history of bedwetting was associated with almost a fourfold increase in odds of persistent wetting [odds ratio and 95% confidence interval: 3.60 (1.75-7.40)]. In general, difficult temperament and behaviour/emotional problems were most strongly associated with combined (day and night) wetting, e.g. children with behavioural difficulties had increased odds of delayed (daytime and nighttime) bladder control [1.80 (1.59-2.03)]. Maternal postnatal depression was associated with persistent (day and night) wetting [2.09 (1.48-2.95)] and daytime wetting alone [2.38 (1.46-3.88)]. Developmental delay, stressful events, and later initiation of toilet training were not associated with bedwetting alone, but were associated with the other UI trajectories. Constipation was only associated with delayed bladder control. We find evidence that different trajectories of childhood UI are differentially associated with biopsychosocial factors. Increased understanding of factors associated with different trajectories of childhood UI could help clinicians to identify children at risk of persistent incontinence.

Diagnosis and management of bladder bowel dysfunction in children with urinary tract infections: a position statement from the International Children's Continence Society

BACKGROUND

We present a consensus view from the International Children's Continence Society (ICCS) on the evaluation and management of bladder bowel dysfunction (BBD) in children with urinary tract infection (UTI). The statement aims to highlight the importance of BBD in the development and recurrence of childhood UTI and its management to reduce its associated morbidity and sequelae.

METHODS

A systematic literature search was done on PubMed, Embase, and Scopus databases until August 15, 2016. Relevant publications concerning BBD and its relationship with UTI among children were reviewed and aggregated for statements of recommendation. Discussion by the ICCS Board and a multi-disciplinary core group of authors resulted in a document available on its website for all ICCS members to review. Insights and feedback were considered with consensus and agreement reached to finalize this position statement.

RESULTS

BBD in children with UTI is summarized. Details regarding epidemiology, pathophysiology, and recommendations for general and family practitioners and pediatricians relating to the evaluation and management of this condition are presented.

CONCLUSIONS

This document serves as the position statement from ICCS, based on literature review and expert opinion providing our current understanding of BBD in children with UTI.

Comparison of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agents in the management of paediatric monosymptomatic nocturnal enuresis: a network meta-analysis

OBJECTIVE

To assess the efficacy of desmopressin, alarm, desmopressin plus alarm, and desmopressin plus anticholinergic agent (AA) therapy in the management of paediatric monosymptomatic nocturnal enuresis (MNE) using a network meta-analysis.

MATERIALS AND METHODS

We searched the electronic databases PubMed, Cochrane Library, EMBASE and Web of Science from inception to 1 March 2018. Randomized controlled trials (RCTs) that compared desmopressin, alarm, desmopressin plus alarm, and desmopressin plus AAs were identified. The network meta-analysis was conducted with software R 3.3.2 and STATA 14.0.

RESULTS

Eighteen RCTs with a total of 1 649 participants were included. The meta-analysis results showed that complete response (CR) and success rates with desmopressin plus AAs were higher than with desmopressin or alarm monotherapy. Success rates for desmopressin plus alarm therapy were higher than for alarm monotherapy. No obvious difference was observed between desmopressin plus AAs and desmopressin plus alarm therapy with regard to CR rate and success rate. The relapse rate with alarm monotherapy was much lower than with desmopressin monotherapy. Adverse events seemed to be infrequently and tolerable for all treatments. The ranking probability results were as follows: desmopressin plus AA ranked first for the outcomes of CR and success, desmopressin plus alarm therapy ranked first for mean number of wet nights per week, and alarm therapy had the lowest relapse rate.

CONCLUSIONS

The network meta-analysis showed that desmopressin had similar efficacy to alarm therapy but a higher relapse rate. Desmopressin plus AA therapy was associated with better efficacy than and a similar relapse rate to desmopressin monotherapy. Desmopressin plus alarm therapy was similar to both desmopressin and alarm monotherapy in efficacy. All treatments, including desmopressin plus AAwere associated with tolerable adverse events; however, additional high-quality studies are needed for further evaluation of these treatments.

Enuresis Management in the Primary Care Pediatrics Clinic

Enuresis is a frequent complaint not always volunteered by parents or patients. The pediatric clinician has to inquire about enuresis to break the secrecy surrounding this symptom that could be related to a more serious underlying renal, endocrine, or psychosocial disease. Determining the type of enuresis is crucial to offer optimal treatment. We present a review for the pediatric clinician to optimize their care of the child with monosymptomatic enuresis. [Pediatr Ann. 2018;47(10):e390-e395.].

An interprofessional approach to managing children with treatment-resistant enuresis: an educational review

Enuresis (intermittent urinary incontinence during sleep in a child aged ≥ 5 years) is commonly seen in paediatric practice. Despite the availability of effective interventions, treatment resistance is encountered in up to 50% of children. In this educational review we attempt to provide insight into the causes of treatment resistance, and offer practical suggestions for addressing this condition using an interprofessional approach. We explore the pathophysiology of and standard treatments for enuresis and discuss why standard treatments may fail. An interprofessional approach to treatment resistance is proposed which utilises the expertise of professionals from different disciplines to address the problems and barriers to treatment. The two interprofessional approaches include a multidisciplinary approach that involves the patient being sent to experts in different disciplines at different times to address their treatment resistance utilising the skills of the respective experts, and an interdisciplinary approach that involves a patient being managed by members of interdisciplinary team who integrate their separate discipline perspectives into a single treatment plan. Although an interdisciplinary approach is ideal, interdisciplinary teams may not be available in all circumstances. Understanding the roles of other disciplines and engaging clinicians from other disciplines when appropriate can still be helpful when treatment resistance is encountered.

Tips for managing treatment-resistant enuresis

Enuresis (bedwetting) is common in school-aged children and can impact health, psychosocial well-being and quality of life. Although effective treatment is available, treatment resistance is encountered in about 50%. This paper discusses the management of treatment-resistant enuresis from a multidisciplinary perspective. Causes of treatment resistance include lower urinary tract problems, constipation, incorrect alarm training techniques, sleep disorders including sleep apnoea and psychological comorbidities. Practical suggestions to address treatment resistance are offered utilising expertise from clinicians from different disciplines.

Assessment and treatment of nocturnal enuresis in children and young people

Nocturnal enuresis - or bed-wetting - is one of the most common chronic conditions of childhood. It has a significant effect on the quality of life of affected children and their families and is associated with several comorbidities, some of which resolve on successful treatment. The causes of this troublesome condition are explored and the principles of assessment and treatment are discussed with reference to National Institute for Health and Care Excellence guidance as well as research. Response to treatment resistance is considered and appropriate onward referral discussed.

Enuresis in children and adolescents with sickle cell anaemia is more frequent and substantially different from the general population

Background

No large studies have examined the prevalence of enuresis, its various forms and risk factors in children with sickle cell anaemia (SCA) in Sub-Saharan Africa using standardised definitions. We determined age and gender-specific prevalence of enuresis and compared the nature of enuresis in children with and without SCA. We also identified predictors of enuresis in children with SCA.

Methods

Caregivers of children with SCA attending a tertiary centre haematology clinic in Nigeria were interviewed using a questionnaire. In addition, a separate questionnaire was completed for every sibling aged 5–17 years whose haemoglobin genotype was known. Enuresis and its various forms were defined using the definitions of the International Children’s Continence Society.

Results

The study involved 243 children with SCA and 243 controls matched for age and sex. The mean age of the study cohort was 9.9 (3.4). Females made up 45.7% of the cohorts. The prevalence of enuresis was 49.4% and 29.6% in children with and without SCA, respectively (p = 0.009). In both groups, the prevalence of enuresis declined with age but remained five times higher at 25% in children with SCA aged 14–17 years compared with controls. Also, children with SCA and enuresis were older, more likely to have non-monosymptomatic enuresis and wet at least three nights per week than controls. Independent predictors of enuresis in children with SCA were a family history of enuresis and young age.

Conclusion

Children with SCA had more frequent and more severe enuresis which persisted to late adolescence than age and sex-matched controls. These features indicate a subset of enuresis that is difficult to treat in the general population. Young age and enuresis in a family member define a subset of children with SCA more likely to have enuresis. Healthcare workers need to discuss enuresis with parents of children with SCA and offer referral to continence services.

Time Course of Treatment for Primary Enuresis With Overactive Bladder

PURPOSE

To characterize the course of treatment for nonmonosymptomatic enuresis with overactive bladder (OAB) in a real clinical setting.

METHODS

Data from 111 OAB patients with moderate to severe enuresis were analyzed. The baseline analysis included a questionnaire, voiding diary, uroflowmetry with postvoid residual urine measurement, and plain abdominal radiography of the kidneys, ureters, and bladder (KUB). Following standard urotherapy for 1 month, anticholinergic medication was administered with or without laxatives. Desmopressin was added if there was a partial response to OAB. Patients were followed every 3 months to evaluate the status of OAB and enuresis. Multivariate analysis was performed to identify predictors associated with the lack of complete response (CR) in enuresis at 12 months.

RESULTS

Following 12 months of treatment, 64% and 88% of patients experienced at least partial response in enuresis and OAB, respectively. Urgency improved more quickly than enuresis, supporting the need to address daytime symptoms before enuresis. Seventy-nine patients (71%) had fecal impaction on KUB and/or subjective constipation. The combination of anticholinergics with either laxatives or desmopressin fared better than anticholinergics alone. Daytime incontinence and anticholinergics- only treatment were associated with a lack of CR during 12 months of treatment.

Conclusions

The data confirmed the validity of addressing OAB before treating enuresis. The results of this study also highlight the need to address fecal impaction. Patients should be counseled about the need for a prolonged course of treatment before starting treatment. Anticholinergics should be accompanied with either desmopressin or laxatives for better control of enuresis.

Clinical management of nocturnal enuresis

Nocturnal enuresis (NE) is a common health problem. Approximately 10% of 7-year-old children wet the bed regularly during sleep. Enuresis can be categorized into monosymptomatic (MEN) and nonmonosymptomatic (NMEN) forms. MEN occurs without any other symptoms of bladder dysfunction. NMEN is associated with dysfunction of the lower urinary tract with or without daytime incontinence. The rate of comorbid gastrointestinal, behavioral, and emotional disorders is elevated depending upon the subtype of NE. A careful clinical history is fundamental to the evaluation of enuresis. Diagnostic procedures include medical history and psychological screening with questionnaires, bladder and bowel diary, physical examination, urinalysis, ultrasound, and examination of residual urine. The mainstay of treatment is urotherapy with information and psychoeducation about normal lower urinary tract function, the underlying cause of MEN, disturbed bladder dysfunction in the child with NMEN and instructions about therapeutic strategies. Alarm therapy and the use of desmopressin have been shown to be effective in randomized trials. Children with NMEN first need treatment of the underlying daytime functional bladder problem before treatment of nocturnal enuresis. In patients with findings of overactive bladder, besides urotherapy, anticholinergic drugs may be useful.

Management of nocturnal enuresis in Taiwan: Consensus statements of the Taiwan enuresis expert committee

Nocturnal enuresis causes significant psychological distress to affected children and their family and requires appropriate management. A 12-member expert committee of pediatric urologists and pediatric nephrologists in Taiwan with extensive experience in treating enuresis was established to develop consensus statements and a recommended treatment algorithm for the management of patients with nocturnal enuresis in Taiwan after careful consideration of current evidence, existing guidelines, and expert opinion as well as local practice and culture. The finalized consensus statements were reviewed by and have received endorsement from the Taiwan Urological Association and the Taiwan Pediatric Association. Patients with suspected enuresis should undergo a thorough initial assessment to fully evaluate urinary signs and symptoms and to rule out underlying causes of diurnal and nocturnal incontinence. Behavioral therapy is recommended throughout the course of management. Desmopressin in the fast-melting formulation is the recommended first-line pharmacological treatment. Combination therapy may be effective in patients who have failed first-line treatment. These consensus statements and a recommended treatment algorithm were created by the expert committee to provide practical support for clinical decision making by physicians in Taiwan.
