The effectiveness of parasacral transcutaneous electrical nerve stimulation in the treatment of monosymptomatic enuresis in children and adolescents: a systematic review.

BACKGROUND: Parasacral Transcutaneous Electrical Nerve Stimulation (PTENS) is a treatment used in enuresis refractory to first-line treatment. This review aimed to evaluate the effectiveness of PTENS in treating monosymptomatic enuresis (MNE) in children and adolescents. METHODS: The study followed the Preferred Reporting Items for Systematic (PRISMA) guidelines. The search was carried out in the following databases: MEDLINE (via PubMed), Web of Science, SCOPUS, Central Cochrane Library and Physiotherapy Evidence Database (PEDro). The selected studies were randomized clinical trials (RCTs). The "Risk of Bias tool for randomized trials" and the "Risk of Bias VISualization" were used to analyze the risk of bias. RESULTS: Of the 624 studies selected, four RCTs were eligible. Three included 146 children and adolescents aged between six and 16.3 years and used similar PTENS protocols with a frequency of 10 Hz, pulse duration of 700 µs and 20 minutes three times/week. One study enrolled 52 patients aged seven to 14 years used PTENS at home, with a pulse duration of 200 µs and 20 to 60 minutes twice/day. Risk of bias was observed in three studies due to results' randomization and measurement. Two studies showed a partial response with a reduction in wet nights, one a complete response in 27% of patients, and one showed no improvement. CONCLUSION: PTENS reduces wet nights' frequency but does not cure them, except in 27% of patients in one study. Limited RCTs and data heterogeneity are limitations.

Translation, cross-cultural adaptation and validation of the Short Screening Instrument for Psychological Problems in Enuresis for use in Brazil (SSIPPE-Br).

OBJECTIVE: Enuresis is associated with attentional and emotional comorbidities in 20 to 30 % of cases. The Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) is a questionnaire that allows the initial screening of these comorbidities. This study aimed to translate, culturally adapt, and validate the SSIPPE for Brazilian children and adolescents (SSIPPE-Br). METHODS: Six steps were performed for translation and cross-cultural adaptation: translation, synthesis of translations, back-translation, preparation of the pre-final version of the translated instrument, test of comprehensibility of the pre-final version of the tool, and elaboration of the instrument cross-culturally adapted for Brazil, named 13-itens version SSIPPE-Br. To validate the SSIPPE-Br, a cross-sectional study was carried out, in which the validated Brazilian version of the Child and Adolescent Behavior Inventory (CABI) was used. RESULTS: Validation was performed on 127 children and adolescents with a mean age of 9.7 ± 2.8 years, 48 % male. The reliability was estimated using Cronbach's alpha, ranging from 0.86 to 0.89, indicating good internal consistency. The factorial analysis had a good agreement adjustment (KMO 0.755, Bartlett's test < 0.001) and explained 70.5 % of the data variability. In the reproducibility analysis, the Kappa coefficient ranged from 0.94 to 1, which can be considered almost perfect. A highly significant (p-value < 0.001) and direct correlation existed between the three SSIPPE-Br domains and all evaluated CABI domains. CONCLUSION: The SSIPPE-Br is a valid and reliable tool for emotional problems screening and ADHD symptoms in children and adolescents with enuresis whose first language is Brazilian Portuguese.

Dynamic and static ultrasound features predictive of vesicoureteral reflux and renal damage in children and adolescents with neurogenic bladder.

PURPOSE: This study aimed to analyze the diagnostic accuracy of dynamic and static ultrasound (DSUS) in detecting vesicoureteral reflux (VUR) and renal scarring in a cohort of children with neurogenic bladder (NB). MATERIALS AND METHODS: A retrospective, longitudinal, observational study was conducted using the Reporting Diagnostic Accuracy Studies guideline. The DSUS (index test) data were compared with voiding cystourethrography (VCUG) and renal scintigraphy 99mTc-dimercaptosuccinic (reference tests). Overall performance for predicting VUR and renal scarring was assessed using renal pelvic diameter (RPD)/distal ureteral diameter and renal parenchymal thinning on DSUS, respectively. RESULTS: A total of 107 patients (66 girls, median age 9.6 years) participated. Seventeen patients (15.9%) presented VUR, eight bilateral. For overall reflux grade, the AUC was 0.624 for RPD and 0.630 for distal ureteral diameter. The diagnostic performance for detecting high-grade VUR was slightly better for DSUS parameters. The AUC was 0.666 for RPD and 0.691 for distal ureteral diameter. The cut-offs of 5 mm for RPD and 6.5 mm for distal ureteral diameter presented the best diagnostic odds ratio (DOR) to identify high-grade VUR. The increase of RPD during detrusor contractions showed an accuracy of 89.2%. The thinness of renal parenchyma presented an accuracy of 88% for renal scarring. CONCLUSION: DSUS predicts VUR and renal scarring in children with NB with fair to good accuracy, and all measurements exhibited a high negative predictive value (NPV). The increase in RPD during voiding or detrusor contractions proved to be the most accurate parameter for indicating the presence of VUR in this study.

Validation of the Vancouver Symptom Score Questionnaire for bladder and bowel dysfunction for Brazilian children and adolescents

ABSTRACT Objective: This study aimed to translate, and perform a cross-cultural adaptation, and validation of the Vancouver Symptom Score (VSS) for bladder and bowel dysfunction (BBD) for Brazilian children and adolescents Materials and Methods: Six steps were performed for the translation and cross-cultural adaptation: (1) translation, (2) synthesis of translations, (3) back-translation, (4) pre-final version of the translated instrument, (5) pilot test and degree of comprehensibility and (6) elaboration of the Brazilian version of the VSS. For validation, the Brazilian Dysfunctional Voiding Score (DVSS) questionnaire was used. Results: Validation was performed on a sample of 107 children and adolescents with a mean age of 9.2 ± 2.84 years, presenting BBD and 107 without BBD (control group-CG). There was a positive correlation (r = 0.91, 95% CI 0.88 to 0.93, p < 0.0001) between total VSS score and total DVSS score. VSS was higher in patients with BBD (p < 0.0001). The internal consistency estimated by Cronbach's alpha was 0.87 for patients with BBD. The VSS showed excellent diagnostic accuracy in detecting cases, with an area under the ROC curve of 98% (95% CI 0.96 to 0.99, p < 0.001). A cut-off value of >11 points produced a sensitivity of 100% (95% CI 96.4% to 100%) and a specificity of 91.8% (95% CI 85.1% to 95.6%). Conclusion: The translated, cross-culturally adapted, and validated VSS for the Brazilian population is a reliable and valid tool to identify symptoms of BBD in children and adolescents aged five to 16 years, whose first language is Brazilian Portuguese.

Relationship between primary monosymptomatic enuresis and process toilet training: a case-control

ABSTRACT Objective: Primary monosymptomatic nocturnal enuresis (PMNE) is a prevalent condition in childhood, and the pathophysiology is multifactorial. This study investigated the relationship between the toilet training process (TT) and PMNE in children and adolescents. Patients and Methods: A case-control study was carried out from 2015 to 2020. The presence of PMNE was identified according to International Children's Continence Society criteria. A semi-structured questionnaire was applied to assess TT. Results: The study included 103 children and adolescents with PMNE and 269 participants with normal psychomotor development without PMNE (control group [CG]). Readiness signals were more remembered and less frequent in participants with PMNE (p=0.001) when compared to control group. No differences were found between the groups regarding the onset age of the daytime TT (p= 0.10), the nocturnal TT (p=0.08), the acquisition of daytime continence (p=0.06), and the type of equipment used for the TT (p=0.99). The use of Child-Oriented approach in group of children with enuresis was lower than in controls [87.4% (90/103) versus 94% (250/266)], respectively (OR= 0.44, 95% CI 0.21-0.94, p = 0.039). Conclusions: The age of onset of TT, acquisition of daytime continence, and the type of equipment were not associated with higher occurrence of PMNE. On the other hand, the Child-Oriented approach was a protective factor for the occurrence of PMNE.

Relationship between toilet training process and primary nocturnal enuresis in children and adolescents - A systematic review.

INTRODUCTION: Primary nocturnal enuresis (PNE) affects the quality of life of children and families and may lead to low self-esteem and social isolation. The pathophysiology of enuresis is multifactorial. This systematic review aimed to investigate the relationship between toilet training (TT) and PNE in children and adolescents. METHODS: We searched for articles about TT and PNE in MEDLINE (via PubMed), SCOPUS and WEB of SCIENCE databases. The Preferred Reporting Items for Systematic Reviews (PRISMA) statement was used to guide the systematic review. Prior to the study, the review protocol was registered and approved in PROSPERO under the protocol CRD42021270976. The Risk of Bias in Non-Randomized Studies of Exposures (ROBINS-E) was used to analyze the biases of the select studies. RESULTS: A total of 570 studies were initially selected. Of these, eight articles were included in this systematic review, with a total number of 5990 participants aged between 5 and 18 years diagnosed with PNE. Seven of the eight articles reported that prolonged use of disposable diapers for more than one-year, late initiation of the TT process or non-acceptance of the Assisted Infant TT or Elimination Communication approach, use of coercive approaches, and complete of TT after 24 months of age increase the risk of enuresis. Only one of the selected studies did not find an association between the start of TT after 24 months of age and the presence of isolated PNE. Three studies did not mention the approach used in the TT process. CONCLUSION: Most of the articles reviewed showed that prolonged diaper use, delay in the start or completion of the TT and use of coercive approaches increase the risk of enuresis. On the other hand, one study showed no relationship between the start of TT after 24 months of age and the presence of isolated enuresis.

Association between Attention Deficit Hyperactivity Disorder and lower urinary tract symptoms in children and adolescents in a community setting.

INTRODUCTION: The present study aims to investigate the prevalence of lower tract urinary symptoms (LUTS) and symptoms of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents and their association in a community setting using validated scoring instruments. MATERIALS AND METHODS: A cross-sectional study was carried out from February 2015 to December 2019, during which the parents or guardians of 431 children and adolescents from 5 to 13 years of age, attending a general pediatric outpatient clinic were interviewed. RESULTS: The prevalence of ADHD symptoms and LUTS were 19.9% and 17.9%, respectively. Of the 82 children and adolescents with ADHD, 28% (23) had LUTS (OR 2.31, 95% CI 1.28 to 3.75, p=0.008). Mean total DVSS score in children in the group of children presenting ADHD symptom was significantly higher than those without ADHD symptom (10.2±4.85 vs. 4.9±2.95, p=0.002). Urgency prevailed among LUTS as the most frequent symptom reported by patients with ADHD symptoms (p=0.004). Analyzing all subscales of the DVSS, the items "When your child wants to pee, can't he wait? "Your child holds the pee by crossing his legs, crouching or dancing?" were higher in those with ADHD symptoms (p=0.01 and 0.02, respectively). Functional constipation was present in 36.4% of children with LUTS and 20.7% without LUTS (OR 4.3 95% CI 1-5.3 p=0.001). CONCLUSION: Children and adolescents with ADHD symptoms are 2.3 times more likely to have LUTS. The combined type of ADHD was the most prevalent among them.

Attention deficit and hyperactivity disorder and nocturnal enuresis co-occurrence in the pediatric population: a systematic review and meta-analysis.

BACKGROUND: Attention deficit and hyperactivity/impulsivity disorder (ADHD) and enuresis are common behavioral disorders in childhood, impacting adolescence and adult life. Enuresis (NE) is an incontinence disorder frequently observed in children with ADHD. The relationship between ADHD and NE has been a matter of debate. OBJECTIVES: We aimed to verify the relationship between ADHD and enuresis and how these conditions can modify each other during development. Using PRISMA guidelines, under the PROSPERO registration number CRD42020208299, we systematically searched the literature and conducted a meta-analysis to answer the following question: how frequent is ADHD and enuresis comorbidity? Twenty-five studies were fully read, and data from seven less heterogeneous case-control studies were pooled to estimate enuresis prevalence comparing ADHD and control samples, whereas six studies were combined to evaluate ADHD frequencies in children with and without enuresis. RESULTS: We found the ADHD rates in children with enuresis are similar to the enuresis rates in the group of children with ADHD. The presence of ADHD and enuresis comorbidity does not seem to play a role in gender distribution and the presence of other comorbidities in comparison to controls. However, enuresis seems to persist for more time in children with ADHD. LIMITATIONS: The selected papers differed in study type, research question, samples, and controls utilized. CONCLUSIONS: Our systematic review with meta-analysis supports the reciprocal association between enuresis and ADHD. Further studies are necessary to build more robust evidence.

Mental disorders in children and adolescents with lower urinary tract dysfunction.

Lower urinary tract dysfunction (LUTD) affects about 2-25% of the pediatric population and is associated with the presence of emotional and behavioral disorders. The purpose of this literature review was to identify studies focusing on mental disorders in children and adolescents with LUTD. The prevalence of these disorders is high - ranging from about 20 to 40% - in children with symptoms of LUTD and comorbidities. The presence of emotional and behavioral symptoms impact in the treatment of the dysfunction, self-esteem of patients and caregivers. Despite the association between mental/behavioral disorders and LUTD be well documented in the literature, the investigation of psychiatric symptoms in clinical practice is still not common and should be stimulated.

Resumo A disfunção do trato urinário inferior (DTUI) afeta cerca de 2 a 25% da população pediátrica e se associa à presença de transtornos emocionais e de comportamento. O objetivo dessa revisão bibliográfica foi selecionar estudos que enfoquem os transtornos mentais em crianças e adolescentes com DTUI. A prevalência destes transtornos é elevada - variando de cerca de 20 a 40% nas crianças com sintomas da DTUI e comorbidades. A presença de sintomas emocionais e comportamentais impacta no tratamento da disfunção, na autoestima dos pacientes e também nos cuidadores. Apesar da associação entre transtornos mentais/comportamentais e DTUI estar bem documentada na literatura, a investigação de sintomas psiquiátricos na prática clínica ainda é pouco realizada e deve ser estimulada.

Impact of an interdisciplinary approach in children and adolescents with lower urinary tract dysfunction (LUTD).

INTRODUCTION: The lower urinary tract dysfunction (LUTD) corresponds to changes in the filling or emptying of urine caused by neurogenic, anatomical and functional alterations. OBJECTIVE: To evaluate the impact of treatment in children and adolescents with LUTD. METHODS: Historical cohort of 15 year follow-up with the participation of 192 patients (123F, 69M), aged 0.1 to 16.8 years, analyzed at admission (T0) and at final follow-up (T1). Most patients belong to a neurologic bladder dysfunction group (60.4%). The treatment was uroterapy with behavioral and cognitive intervention, timed voiding, oral hydration, laxative diet, biofeedback, sacral nerve stimulation, clean intermittent catheterization (CIC), anticholinergic therapy, rectal enema, treatment of urinary tract infection (UTI) and, in refractory cases, surgical procedures such as continent and incontinent urinary diversion (vesicostomy), bladder augmentation and conduit for performing antegrade colonic enema. RESULTS: The main symptoms were daytime urinary incontinence (82.3%), the non-monosymptomatic nocturnal enuresis (78.6%), fecal incontinence (54.2%) and constipation (47.9%). There was a significant reduction of urinary tract infection (p = 0.0027), daytime urinary incontinence (p < 0.001), nocturnal enuresis (p < 0.001), fecal incontinence (p = 0.010) and of vesicoureteral reflux (p = 0.01). There was significant increase in the use of CIC (p = 0.021), of anticholinergic therapy (p < 0.001) and decrease of chemoprophylaxis (p < 0.001). CONCLUSION: This study showed that treatment of LUTD in children must be individualized, and requires constant monitoring of clinical, laboratory and imaging to minimize the risk of kidney damage.

Aspectos atuais no diagnóstico e abordagem da infecção do trato urinário / Current aspects in the diagnosis and approach to urinary tract infection

O objetivo deste artigo de revisão é apresentar as mais recentes diretrizes no manejo de infecção do trato urinário (ITU), salientando que há uma tendência atual a estudos de imagem menos agressivoseao uso mais restritivo da quimioprofilaxia. Tem surgido preocupação sobre a exposição desnecessária de radiação ionizante e o caráter invasivo de alguns procedimentos. Outro ponto discutido é a relação causal do refluxo vesicoureteral (RVU) e cicatrizes renais, o que tem sido o foco de vários estudos. Tem surgido preocupação sobre a exposição desnecessária dos pacientes à radiação ionizante e o caráter invasivo de alguns procedimentos. O risco de infecção também tem sido alvo de discussão. Com o aprimoramento da ultrassonografia pré-natal tem sido sugerida aabordagem top-down para investigação da ITU febril. Finalmente, aborda-se a associação do RVU e a disfunção do trato urinário inferior (DTUI) com a ITU.

The objective of this review article is to present the latest guidelines on the management of urinary tract infection (UTI) highlighting that there is a current trend towards less aggressive image studies and more restrictive use of chemoprophylaxis. The unnecessary exposure to ionizing radiation and the invasive nature of some procedures have raised concerns. Another point discussed is the causal relationship of vesicoureteral reflux (VUR) and renal scarring, which have been the focus of several studies. The risk of infection has also been the subject of discussion. With the improvement of prenatal ultrasound, the top-down approach to investigate febrile UTI has been suggested. Finally, the association between VUR and lower urinary tract dysfunction (LTUD) and UTI is also assessed.

[Lower urinary tract dysfunction: a common diagnosis in the pediatrics practice]. / Disfunção do trato urinário inferior: um diagnóstico comum na prática pediátrica.

Lower urinary tract dysfunction indicates an abnormal function of the lower urinary tract to the child's age, which can lead to loss of coordinated capacity storage and elimination of urine. It is a common entity in children, although under-diagnosed in clinical practice, and that, besides representing a risk to the upper urinary tract, causes an emotional embarrassment to parents and children, due to urinary incontinence and frustration in dealing with the problem. The acquisition of daytime urinary continence occurs in most children until age 4 and night, until 5 years of age. After this age, urinary incontinence becomes a social problem. Despite the clinical importance often parents are unaware of the symptoms of this dysfunction. This article aims to address the key issues related to the diagnosis of this dysfunction.

Disfunção do trato urinário inferior: um diagnóstico comum na prática pediátrica / Lower urinary tract dysfunction: a common diagnosis in the pediatrics practice

Disfunção do trato urinário inferior indica uma função anormal do trato urinário inferior para a idade da criança, que pode levar à perda da capacidade coordenada de armazenamento e eliminação de urina. É uma entidade comum em crianças, embora subdiagnosticada na prática clínica, e que, além de representar um risco para o trato urinário superior, causa um constrangimento emocional aos pais e às crianças, devido à incontinência urinária e à frustração em lidar com o problema. A aquisição da continência urinária diurna ocorre na maioria das crianças até os 4 anos e a noturna até os 5 anos de idade. Após esta idade, a incontinência urinária torna-se um problema social. Apesar da importância clínica, muitas vezes, os pais desconhecem os sintomas dessa disfunção. Esse artigo tem como objetivo abordar os principais aspectos relacionados ao diagnóstico dessa disfunção.
