Feasibility Analysis of the 3-Day Urination Diary for Children With Enuresis

This study aimed to evaluate the feasibility of the 3-day micturition diary for children with enuresis. We included 53 such children (March 2020-December 2021), who kept a urination diary and filled out a questionnaire. The data were retrospectively analyzed; the differences in completion rate, sensitivity, and specificity between the urination diaries recorded for 3 and 7 days were compared; and factors affecting the completion of the urination diary were assessed. Compared with the 7-day micturition diary, the 3-day micturition diary is easier to complete; the data tend to be more credible; and its application in children with enuresis is feasible.

First uninterrupted sleep period in children and adolescents with nocturnal enuresis: Added value in diagnosis and follow-up during therapy

BACKGROUND

The first uninterrupted sleep period (FUSP, time up to the first episode of enuresis/nocturia after falling asleep) is a frequently investigated parameter in adults with nocturia, as it correlates with quality of life. However, it has not been included in pediatric enuresis studies.

AIM

Investigate FUSP, circadian renal water and sodium handling, as well as sleep quality before and after desmopressin therapy in enuresis.

MATERIALS AND METHODS

We conducted a post hoc analysis of a prospective study in 30 treatment-naïve children with enuresis who underwent a video-polysomnography and a 24-h urine concentration profile before and after 6 months of desmopressin therapy. We analyzed FUSP, periodic limb movements in sleep (PLMS), and arousal indexes and their correlations with the urinary parameters.

RESULTS

Sixteen children with a mean age of 10.9 ± 3.1 years had full registrations and were included in this subanalysis. After therapy, FUSP was significantly longer (p < 0.001), and the PLMS index was lower (p = 0.023). Significant differences in the circadian rhythm of diuresis (night/day diuresis, p = 0.041), nocturnal urinary osmolality (p = 0.009), and creatinine (p = 0.001) were found, demonstrating the increase of urinary concentration overnight by desmopressin, as well as a significant antidiuretic effect (diuresis [p = 0.013] and diuresis rate (p = 0.008). There was no correlation between the difference of FUSP, PLMS index, and urinary parameters. Nevertheless, despite this study being underpowered, there are indications of a correlation between nocturnal diuresis and diuresis rate.

RESULTS

Our results support the need for further research regarding FUSP in children with enuresis, in accordance with nocturia studies in adults, as this parameter could be valuable in the follow-up and evaluation of therapeutic strategies for enuresis.

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 Beliefs About the Causes, Treatments, and Medical Assistance for Children With Nocturnal Enuresis in the Eastern Region of the Kingdom of Saudi Arabia

OBJECTIVE

To assess parental beliefs about the causes, treatment, and necessity for medical assistance for children with nocturnal enuresis (NE).

METHOD

A self-administered survey questioned parents' beliefs about NE, including causes and at-home behavioral therapy. We evaluated the association between demographic characteristics and the tendency to seek medical advice for NE.

RESULT

The questionnaire received responses from 1232 individuals, 77.1% of whom were female and 82.9% of whom were 30 years of age or older. Psychological issues (53.5%) and laziness to get up (47.6%) were the most often believed causes of NE. Two frequent at-home behavioral therapies chosen by participants were voiding before bedtime and restricting fluid intake at night (73.4% and 70%, respectively). However, only 6.9% of respondents believe that a bedwetting alarm is an effective treatment. The two most frequently reported reasons for not seeking medical attention were parents' belief that their child will eventually outgrow bedwetting (34.1%) and "parents or children's embarrassment" (21.8%). The chi-squared test was used to evaluate the association between demographic characteristics and seeking medical advice. Participants with a single child were more likely than those with more than three children to take their child to the doctor (61.5% vs. 48.6%, respectively). Also, parents who don't have NE-afflicted children were more open to consider seeking medical advice for NE therapy (if their children developed it in the future) compared to parents who already have children with NE.

CONCLUSION

Parents in the Eastern region of Saudi Arabia hold various misconceptions about the causes and treatment of NE. Only 52.1% of parents would take their child to see a doctor if wetting the bed and only 48.1% of parents were aware of effective treatments for NE. These results emphasize that healthcare practitioners need to provide proper information to raise public awareness of NE.

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

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.

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.

Reduced bladder capacity without daytime voiding symptoms with nocturnal enuresis

BACKGROUND

This study aimed to evaluate the prevalence of monosymotomatic nocturnal enuresis (MSNE) with reduced bladder capacity in children with primary nocturnal enuresis (NE) and to suggest treatment outcomes.

METHODS

This study retrospectively evaluated 54 children (30 males, 24 females; median age: 8; range: 5-14) who were newly diagnosed with primary NE from November 2017 to October 2019. Reduced bladder capacity in MSNE was defined when a patient's maximal voided volume (MVV) from his or her voiding diary was 75% or less than estimated functional bladder capacity ([age + 1] x 30 mL) for his or her age and there were no daytime lower urinary tract symptoms (LUTS) as assessed using history taking and questionnaires.

RESULTS

Nineteen (35.2%) of 54 children with newly diagnosed primary NE did not report daytime LUTS. Fifteen children (27.8%) had a reduced bladder capacity and were prescribed anticholinergic or beta-3 agonist. After three months of medication, MVV significantly increased from 117.5 mL to 183.3 mL (P = 0.010), but frequency showed no significant change from 5.7 to 4.9 times a day. Improvement in enuresis occurred completely and partially in 41.7% and 25% of participants, respectively.

CONCLUSIONS

The prevalence of reduced bladder capacity without daytime voiding symptoms was relatively high as 27.8% in children newly diagnosed with primary NE. In primary MSNE, reduced bladder capacity should be investigated using a frequency-volume chart in addition to thorough history taking or questionnaires. Anticholinergics or beta-3 agonists for MSNE with reduced bladder capacity are effective at increasing the bladder capacity of these patients.

Evaluation of a new frequency-volume chart for children with primary monosymptomatic nocturnal enuresis: a prospective, comparative study

INTRODUCTION

To improve compliance with voiding diaries in children with primary monosymptomatic nocturnal enuresis (PMNE), a new modified 3-day weekend frequency-volume chart (FVC) was designed, and the compliance and validity of this modified FVC was evaluated by comparing with the International Children's Continence Society (ICCS) recommended voiding diary.

METHODS

A total of 1200 patients with PMNE were enrolled in the study from 13 centers in China and were randomly assigned to record this modified FVC or the ICCS-recommended voiding diary. The primary outcome measure was the compliance, assessed by comparing the completing index and the quality score of diaries between two groups. The secondary outcome measure was the validity, evaluated by comparing the constituent of subtypes, micturition parameters and response rate to desmopressin.

RESULTS

Among the 1200 participants enrolled in the study, 447 patients completed the ICCS-recommended voiding diary and 469 completed the modified diary. The diurnal completing index and the quality score of the modified FVC group were better than those of the ICCS group. In addition, there was no significant difference between these two groups in the subtype classification, or in the response rate to desmopressin.

CONCLUSIONS

The modified FVC could be applied to obtain the voiding characteristics of children with PMNE as the ICCS-recommended voiding diary does and offers a reasonable and better choice for children with PMNE from the unselected population in the future.

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.

Prevalence, Risk Factors, and Psychological Effects of Primary Nocturnal Enuresis in Chinese Young Adults

Purpose

This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China.

Methods

An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included.

Results

In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE.

Conclusions

In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.
