Long-term followup of children with nocturnal enuresis: increased frequency of nocturia in adulthood

Differences in bladder neck angles between female patients with overactive bladders and healthy peers

AIM

The aim of this study was to compare the differences between angles of bladder neck in girls with overactive bladder and those in healthy ones using transabdominal ultrasonography.

MATERIALS AND METHODS

This study consists of 28 girls complicated with overactive bladder (Group I) and 40 healthy girls (Group II). The anteroposterior vesical wall angle (APVA), urethroposterior vesical wall angle (UPVA), urethroanterior vesical wall angle (UAVA), thickness of bladder mucosa, distance of urethral orifices, and distance between ureter and urethra orifice were measured in supine position using transabdominal ultrasonography. The results were compared between the two groups.

RESULTS

UAVA in Group I was higher than Group II (135.2 ± 12.2 mm vs. 117.4 ± 14.0 mm; p = 0.009). UPVA was smaller in Group I than Group II (114.6 ± 19.5 mm vs. 135.3 ± 16.5 mm; p = 0.014). The distance between the ureteral orifices was 31.8 ± 8.5 mm in Group I and 17.0 ± 4.1 mm in Group II (p < 0.001). There was no statistically significant difference between groups in terms of APVA, bladder mucosa thickness, and distance between ureter and urethra orifice (p > 0.05).

CONCLUSION

Bladder neck dynamics may play an important role in overactive bladder pathophysiology due to differences in UPVA, UAV, and location of ureteral orifices in this patient population.

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.

The role of renal circadian biorhythms in lifelong LUTS

INTRODUCTION

This article delves into the intricate relationship between kidney function, diuresis, and lower urinary tract symptoms (LUTS) throughout the transitions of the human lifespan. It explores circadian regulation of urine production, maturation of renal function from birth to adulthood, and effects of aging on kidney function and LUTS. The complex connections between these factors are highlighted, offering insights into potential interventions and personalized management strategies.

METHODS

An international panel of seven experts engaged in online discussions, focusing on kidney function, diuresis, and LUTS throughout life. This manuscript summarizes expert insights, literature reviews, and findings presented during a webinar and subsequent discussions.

RESULTS

Renal function undergoes significant maturation from birth to adulthood, with changes in glomerular filtration rate, diuresis, and tubular function. A circadian rhythm in urine production is established during childhood. Adolescents and young adults can experience persistent enuresis due to lifestyle factors, comorbidities, and complex physiological changes. In older adults, age-related alterations in kidney function disrupt the circadian rhythm of diuresis, contributing to nocturnal polyuria and LUTS.

CONCLUSION

The interplay between kidney function, diuresis, and LUTS is crucial in understanding lifelong urinary health. Bridging the gap between pediatric and adult care is essential to address enuresis in adolescents and young adults effectively. For older adults, recognizing the impact of aging on renal function and fluid balance is vital in managing nocturia. This holistic approach provides a foundation for developing innovative interventions and personalized treatments to enhance quality of life for individuals with LUTS across all stages of life.

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.

Analysis on fluid intake and urination behaviors among the elderly in five cities in China: a cross-sectional study

Background

Fluid intake in the elderly may influence urination behaviors and further influence their health status. This study investigated the behaviors of fluid intake, urination and their relationships among the elderly in China.

Methods

Stratified random sampling was used to recruit the elderly participants who met the inclusion criteria from five cities in China. Participants' total fluid intake (TFI) level was investigated using a validated 7-day 24 h fluid intake questionnaire. Their urination behaviors in real time were also recorded using a validated 7-day 24 h urination behavior record.

Results

A total of 524 participants completed the study, including 233 males and 291 females. The average age was 69.7 years. The median daily TFI was 1,241 mL, with a frequency of 8.1 times per day. Approximately 73.3% of the participants did not reach the amount of adequate fluid intake (1.7 L for males and 1.5 L for females) recommended in China. Fluid intake in the morning, afternoon, and evening among participants was 594 mL, 305 mL and 342 mL, with a frequency of 3.0 times, 1.7 times, and 2.0 times, respectively. The median urination frequency was 7.4 times per day. The percentage of participants who urinated >7 times during the day was 44.3%. The percentage of participants who urinated ≥1 time at night was 77.5%. Age and BMI were not the main influence factors for fluid intake and urination behaviors. The preliminary analysis showed that higher TFI, plain water intake, dairy products intake, and fluid intake frequency were significantly associated with higher urination frequency (t = 6.553, p < 0.05; t = 5.291, p < 0.05; t = 4.667, p < 0.05; t = 13.413, p < 0.05). Higher fluid intake per time was significantly associated with lower urination frequency (t = -3.562, p < 0.05). Correlations between TFI, fluid intake frequency, fluid intake in night, fluid intake frequency in night and urination at night were also found (r = 0.114, p < 0.05; r = 0.091, p < 0.05; r = 0.146, p < 0.05; r = 0.331, p < 0.05).

Conclusion

Fluid intake was inadequate in terms of the elderly participants. Participants with higher fluid intake and frequency in night had a greater incidence of nocturia. Thus, correcting fluid intake behaviors can improve urination behavior and promote health.

Evaluation of the influence of a history of childhood nocturnal enuresis on nighttime urinary frequency and the causes of nocturia in adults

OBJECTIVES

To examine whether a history of nocturnal enuresis affects nighttime urinary frequency and to evaluate nocturia etiologies in adults.

METHODS

A total of 143 participants with at least one episode of nocturia per night were included in this study. The self-reported questionnaire collected data on demographic characteristics, medical history, history of nocturnal enuresis in elementary school, lower urinary tract symptoms, and frequency-volume charts.

RESULTS

A history of nocturnal enuresis was observed in 52.4% of participants. However, night-time urinary frequency was significantly lower in participants with a history of nocturnal enuresis in elementary school than in those without such history. On multivariate analysis, a history of nocturnal enuresis was also negatively associated with nighttime urinary frequency (p<0.01). There was a collinearity effect between age and nighttime urinary frequency. A history of nocturnal enuresis did not affect the presence of nocturnal polyuria or overactive bladder in participants. However, sleep disturbances were fewer in participants with a history of nocturnal enuresis (odds ratio 0.404).

CONCLUSIONS

A history of nocturnal enuresis might be negatively associated with nighttime urinary frequency due to fewer sleep disturbances. Further, progression of nocturia may depend on conditions, such as age and acquired diseases.

Assessment and Treatment of Nocturia in Neurological Disease in a Primary Care Setting: Systematic Review and Nominal Group Technique Consensus

CONTEXT

Neurological disease can affect the rate of urine production and bladder storage function, increasing nocturia severity, with additional risks if mobility or cognition is impaired.

OBJECTIVE

To conduct a systematic review (SR) of nocturia in neurological diseases and achieve expert consensus for management in clinics without neurologist input.

EVIDENCE ACQUISITION

Four databases were searched from January 2000 to April 2020. A total of 6262 titles and abstracts were screened and 43 studies were included for full-text screening. Eleven of these met the inclusion criteria and two studies were identified through other sources. The nominal group technique (NGT) was used to develop consensus in panel comprising experts and public representation.

EVIDENCE SYNTHESIS

Thirteen studies (seven in Parkinson's disease, five in multiple sclerosis) were included, all undertaken in secondary care. Neurological disease severity was incompletely described, and nocturia severity was generally measured subjectively. NGT consensus supported basic neurological assessment, and the use of bladder diaries where neurological impairment permits. Treatments include pelvic-floor muscle training, review of medications, risk mitigation, improving bowel function, therapy for overactive bladder syndrome (if urgency is reported in association with nocturia episodes), treatment of postvoid residual and desmopressin according to licence. Measures to improve mobility and mitigate risk when using the toilet overnight should be considered. Multifactorial issues such as obstructive sleep apnoea and hypoventilation must be considered.

CONCLUSIONS

Nocturia in neurological disease is complex and lacks a robust evidence base, with very little research done in the primary care context. Guidance should be pragmatic, with reduction of risk a key requirement, until a multidisciplinary evidence base can be developed.

PATIENT SUMMARY

People with a neurological disease can suffer severe sleep disturbance because of the need to pass urine several times overnight (called nocturia). We looked at published research and found very little information to help general practitioners in managing this condition. We assembled a group of experts to develop practical approaches for assessing and treating nocturia in neurological disease.

Transition from Childhood Nocturnal Enuresis to Adult Nocturia: A Systematic Review and Meta-Analysis

Purpose

Current literature has suggested a relationship between nocturnal enuresis (NE) in childhood and the development of nocturia later in life as both disorders have similar underlying etiologies, comorbidities, and treatments. The objective was to synthesize the available evidence on the association between childhood NE and later presentation of nocturia.

Methods

PubMed, CINAHL, Scopus, and Google Scholar were searched for peer-reviewed studies published between January 1980 and April 2021. Case–control and cohort studies that reported on childhood NE and current nocturia were included. The PRISMA protocol was followed (PROSPERO ID: CRD42021256255). A random-effects model was applied to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). Risk of bias was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria and with a funnel plot.

Results

Of the 278 articles identified, 8 studies met inclusion criteria. The 6 case–control and 2 prospective cohort studies resulted in a total sample size of 26,070 participants. In a random-effect pooled analysis, childhood NE was significantly associated with the development of nocturia (OR: 1.75, 95% CI: 1.11–2.40). Significant heterogeneity (I² = 92.7%, p < 0.01) was identified among the included studies, which was reflected in an asymmetrical funnel plot. NE and nocturia have similar underlying etiologies of hormonal abnormalities, sleep disorders, physiological disorders, and psychological disorders.

Conclusion

The history of childhood NE is significantly associated with nocturia later in life. The data in this meta-analysis support this transition and identify potential similarities between the two disorders. The sparse number of articles relevant to this topic is a strong indicator of the need for more work on this transition from childhood to maturity. More studies are warranted to further explore the association between NE and nocturia.

Long-term functional and psychosocial outcome in adolescents and young adults treated for lower urinary tract dysfunction in childhood

BACKGROUND

Lower urinary tract dysfunction (LUTD) in childhood might affect lower urinary tract function and psychological wellbeing later in life. This study presents long-term functional outcome, psychological outcome and quality of life (QOL) of adolescents and young adults treated for childhood LUTD compared to healthy age-matched controls. In addition, association with past treatment outcomes is evaluated.

STUDY DESIGN

A single-centre cross-sectional study of former patients treated in childhood (currently 16-26 years old) was conducted. Participants completed a survey composed from validated questionnaires: the Overactive Bladder Questionnaire, the Hospital Anxiety and Depression Scale, the Pediatric Quality of Life Inventory and the Short Form 36 Health Survey.

RESULTS

Fifty-two former patients (out of 133) agreed to participate and returned the survey (mean age 21 ± 4.1 years). Sixty-nine control subjects were included (mean age 21 ± 2.9 years). Urinary tract symptoms were more common in former patients than controls. Storage symptoms more frequently reported were (urge) urinary incontinence, stress urinary incontinence (SUI) and nocturia. Voiding symptoms more frequently reported were intermittency and feeling of incomplete emptying, Fig. 1. There were no differences in urinary tract symptoms or urinary incontinence subdivided by childhood treatment outcome (complete response, partial response or no response), respectively p = 0.17 and p = 0.58. Results of the overactive bladder questionnaire revealed higher urinary symptom bother scores (score 14 versus 5 p < 0.01) and lower disease-specific QOL (score 95 versus 98 p = 0.02) in former patients compared to controls. General QOL and psychosocial wellbeing were not significantly different between the two groups. A childhood treatment duration extending 2,5 years was an independent prognostic factor for subsequent urinary tract symptoms later in life (OR = 1.5, 95% CI 1.1-2.0). Psychological comorbidity was more often present in former patients (35%) versus controls (10%), p < 0.01.

CONCLUSION

Adolescents and young adults treated for childhood LUTD are more prone to report urinary tract symptoms later in life, especially if treatment duration was extensive. However general QOL and psychosocial wellbeing later in life are not or only mildly affected.

Which children are at risk of developing overactive bladder in early adulthood even if lower urinary tract symptoms improve during childhood?

OBJECTIVES

To evaluate more comprehensively the presence of an association between childhood lower urinary tract symptoms and development of adulthood overactive bladder, to determine the group at most risk of overactive bladder in adulthood, and to assess its effects on daily life.

METHODS

A total of 264 patients who were followed up for lower urinary tract symptoms in childhood between 2000 and 2005 were included in this retrospective, cohort study. After a median period of 20 years, these patients with a median current age of 29 (27-35) years were re-evaluated and divided into two groups: those currently with overactive bladder (n = 102, 23.0%), and those without overactive bladder (n = 162, 36.5%). In addition, 180 age-matched overactive bladder patients without a history of childhood lower urinary tract symptoms (n = 180, 40.5%) were included. The primary endpoint was to determine which children are at higher risk of adulthood overactive bladder. The secondary endpoint was to evaluate the effect of history of childhood lower urinary tract symptoms on quality of life in adulthood. The eight-item Overactive Bladder questionnaire, the Pittsburgh Sleep Quality Index, and the Short-Form 36-item Health Survey were administered to all participants. Voiding Dysfunction Symptom Score was evaluated according to childhood medical records.

RESULTS

Overactive bladder in adulthood was observed in 38.6% of patients recovering from childhood lower urinary tract symptoms. They had worse overactive bladder symptom scores and quality of life than those without childhood lower urinary tract symptoms (P < 0.001). Voiding Dysfunction Symptom Score ≥13 (odds ratio 2.54), daytime incontinence (odds ratio 2.01), holding maneuvers (odds ratio 1.82), nocturnal enuresis (odds ratio 1.75) in the pediatric period, and recovery age from all these symptoms of ≥12 years (odds ratio 1.95) were the most unfavorable determinants of development of adulthood overactive bladder.

CONCLUSIONS

Our findings show that children with the above characteristics are at risk of developing overactive bladder later in their lives even if their symptoms improve in childhood.

A prospective survey study of lower urinary tract dysfunction in childhood cancer survivors after vincristine and/or doxorubicin chemotherapy

BACKGROUND

Two chemotherapeutic agents used widely in pediatric oncology are vincristine (VCR) and doxorubicin (DOX), which may cause neuropathy and myopathy, respectively. The study hypothesis is that neurotoxic effects of VCR and/or myotoxic effects of DOX affect bladder physiology and manifest clinically as lower urinary tract dysfunction (LUTD).

PROCEDURE

Based on a priori power analysis, 161 children divided evenly by gender were recruited. Children aged 5-10 years completed the dysfunctional voiding scoring system (DVSS) survey. The study cohort comprised cancer survivors treated with VCR and/or DOX. Healthy controls were recruited from well-child clinic visits. Exclusion criteria included pelvic-based malignancy, pelvic irradiation, pre-existing LUTD, neurologic abnormalities, and treatment with cyclophosphamide/ifosfamide. DVSS scores and presence of LUTD, defined as DVSS scores above gender-specific thresholds (males ≥9, females ≥6), were compared across cohorts.

RESULTS

Median DVSS scores were higher in the study cohort (6 vs. 4, p = .003). Moreover, children in the study cohort were more likely to exceed threshold scores for LUTD (38.8% vs. 21%, p = .014; OR 1.8). Subanalysis by gender revealed female cancer survivors are more likely to report LUTD than controls (57.5% vs. 30%, p = .013, OR 1.9). This did not hold true for males (20% vs. 12.2%, p = .339).

CONCLUSIONS

Childhood cancer survivors who received VCR and/or DOX reported higher rates of LUTD than controls. Female cancer survivors appear more likely to suffer from LUTD than males. Further study with a positive control cohort of cancer survivors who received non-VCR, non-DOX chemotherapy is underway to elucidate the contribution of a cancer diagnosis to LUTD.

The Importance of Understanding Parental Perception When Treating Primary Nocturnal Enuresis: A Topic Review and an Institutional Experience

Primary nocturnal enuresis (PNE) is a common childhood disorder that adversely affects a child’s mental well-being and social life. Our clinical experience showed parents and their child often have significantly different perspective of enuresis, and these differences can affect family dynamics, treatment approaches, and treatment success. Parents’ perception of PNE also influences the likelihood of seeking medical treatment, and we found parents of children with enuresis have markedly different beliefs regarding bedwetting than those of physicians. Because achieving remission for PNE requires parents and their child to actively participate in treatment, assessing their expectancy of success and their beliefs will allow clinicians to adjust treatment goals as necessary. When treating PNE, guidelines consistently recommend incorporating bed alarms as part of the therapy. However, through interviewing parents and treating their children, we found parents preferred medications or other behavioral strategies, such as limiting water intake, because of their convenience. Many parents would complain bed alarms woke them up instead of their child, and they would soon give up on bed alarms. Part of assessing their beliefs includes assessing their confidence in their child being able to wake up to alarms and to persist with treatment. Understanding how they manage and approach setbacks will also determine the treatment modality suited for their child. In this review paper, we detailed our experiences interviewing parents and treating their child with NE with urodynamics and medications at the Changhua Christian Hospital in Taiwan.

Urination behaviours of senior citizens in five Chinese cities: Results of a cross-sectional survey

AIM

To investigate the urination behaviours of senior citizens in China.

METHODS

Stratified random sampling was used to recruit senior citizens who met the inclusion criteria from five cities in China. After training by researchers, participants recorded their urination behaviours in real time by using the validated 7-day 24-hour urination behaviour record, which consisted of frequency of urination, time of urination, urinary urgency and urine colour.

RESULTS

Of the 551 recruited participants, 524 (233 male and 291 female) completed the survey, yielding a completion rate of 95.1%. The median frequency of urination was 7.4 times per day. The frequency of urination was highest among participants in Guangzhou, at 8.0 times per day (χ²  = 29.356; P < .001), and participants in the first percentile body mass index group, at 8.0 times per day (χ²  = 10.344; P = .016). The percentage of participants who urinated >7 times during the day was 44.3%. The percentage of participants who urinated ≥1 time at night was 77.5%. The number of times participants reported feeling no urge to urinate, a strong urge to urinate and an uncomfortable urge to urinate accounted for 59.7%, 62.8% and 24.8% of all records of urinary urgency, respectively. Instances of patients having no urge to urinate, a strong urgent to urinate and an uncomfortable urge accounted for 16.1%, 13.3% and 2.9% of all instances of urination, respectively. The number of times participants whose urine was yellow and dark yellow accounted for 69.1% and 18.9% of all records of urine colour, respectively. Urine with yellow and dark yellow colour accounted for 13.0% and 1.5%, respectively.

CONCLUSION

Unhealthy urination behaviours, including urinating at night and holding back urine, were common among senior citizens. This result can provide information for the prevention and control of urinary system diseases.

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.

Potential associations of adult nocturia. Results from a national prevalence study

AIM

To determine the prevalence of nocturia and associated risk factors in the Colombian population aged ≥18 years old.

METHODS

This is a cross-sectional population-based study conducted in 1060 participants in Colombia. Nocturia was assessed with the Spanish version of the ICIQ-OAB, using the ICS terminology. Descriptive statistics were used to evaluate nocturia prevalence. Logistic regression analysis was carried out to determine the association of nocturia with predefined variables.

RESULTS

The prevalence of nocturia was 55.9% and it was more common in women than men (53.96% vs. 46.04%; p = .004). At least three episodes of nocturia were observed in 20.37% of the participants who had a severe alteration in their quality of life (p < .01). The bivariate model showed an association between nocturia and obesity (odds ratio [OR], 1.69; 90% confidence interval [CI]: 1.22-2.34), diabetes mellitus (OR, 2.99; 90% CI: 1.86-4.83), high blood pressure (OR, 2.04; 90% CI: 1.52-2.72), cardiovascular disease (OR, 1.75; 90% CI: 1.08 - 2.83), depression (OR, 1.89; 90% CI: 1.23-2.89), obstructive sleep apnea (OR, 1.70; 90% CI: 1.17 - 2.46), and childhood enuresis (OR, 1.45; 90% CI: 1.04-2.02). The multivariate model showed an association with obesity (OR, 2.0; 95% CI: 1.14 - 3.51) in women, as well as age ≥ 65 years (OR, 3.18; 95% CI: 1.26 - 8.02) and erectile dysfunction (OR, 3.44; 95% CI: 1.21 - 9.72) in men. Childhood enuresis was significantly associated with nocturia in both genders (OR, 1.61; 95% CI: 1.09 - 2.40 in women and OR, 1.66; 95% CI: 1.09-2.52 in men).

CONCLUSION

There is a significant prevalence of nocturia in our population and a clear association with impaired quality of life. We consider important to inquire about history of childhood enuresis to define the risk of presenting nocturia in adulthood. Nocturia was associated with multiple comorbidities. Obesity and erectile dysfunction play an important role as modifiable risk factor.

Medical history of nocturnal enuresis during school age is an independent risk factor for nocturia in adults: The Nagahama study

AIM

To evaluate the relationship between nocturia and medical history of nocturnal enuresis: two conditions where diurnal urination rhythm is disturbed.

METHODS

The Nagahama study is a longitudinal population-based health survey involving people aged 30-75 years in Nagahama city, Japan. Our analysis included 5,402 participants who completed enuresis and International Prostate Symptom Score questionnaires. Associations between nocturnal enuresis and nocturia were evaluated cross-sectionally and longitudinally with three models: (1) univariate analysis; (2) adjusted for basic characteristics (e.g., age, sex, body mass index, activity, alcohol, and smoking); and (3) adjusted for basic and clinical variables (e.g., hyperglycemia, hyperlipidemia, hypertension, renal insufficiency, insomnia, obstructive sleep apnea, and mental health).

RESULTS

In total, 1,613 participants (29.9%) had a medical history of enuresis. The mean night-time frequency was 0.73 at baseline and 0.85 at the 5-year follow-up. The cross-sectional analysis showed participants with a medical history of enuresis had night-time frequency more often than those without this history (0.84 vs. 0.68, p < .0001). Significant differences were observed in Models 2 (p < .0001) and 3 (p < .0001). The longitudinal analysis showed nocturia progression was significantly related to a history of enuresis, with odds ratios of 1.32 (p < .0001) in Model 1, 1.21 (p < .01) in Model 2, and 1.22 (p < .01) in Model 3.

CONCLUSIONS

Medical history of enuresis during school age was significantly related to nocturia in adulthood in the cross-sectional analysis, and to progression to nocturia in the longitudinal analysis. These two conditions may possess a common causative association.

Amplitude of low-frequency fluctuation of resting-state fMRI in primary nocturnal enuresis and attention deficit hyperactivity disorder

Children with attention deficit hyperactivity disorder (ADHD) and nocturnal enuresis (NE) have similar symptoms, for example, inattention and dysfunction of working memory. We investigate disorder-specific abnormal activity by using the simple resting-state functional magnetic resonance imaging (RS-fMRI) metric amplitude of low-frequency fluctuation (ALFF). About 18 ADHD, NE, and typically developing children were examined by RS-fMRI and the child behavior checklist (CBCL) test. One-way ANOVA were used to compare the ALFF values of the three groups and post hoc was done. We conducted Pearson correlation analysis on the results of the three groups' scales with ALFF values at the discrepant brain areas after then. Significant group effect was found in the bilateral medial prefrontal cortex (MPFC), left inferior temporal gyrus (ITG), left middle temporal gyrus (MTG), cerebellum anterior lobe (CAL), and left inferior parietal lobule (IPL). There was no shared abnormal region for ADHD and NE. Specially, ADHD showed increased ALFF in the bilateral MPFC, left ITG, and CAL and showed decreased ALFF in the left MTG. The children with NE showed increased ALFF in the left IPL. This study reveals the brain mechanism of cognitive changes on ADHD and NE, which provides neuroimaging basis for behavioral differences among different diseases.

Is nocturnal enuresis a predisposing factor for the overactive bladder?

Background/aim

This study aimed to perform a limited observational study to ascertain whether there is statistical support that nocturnal enuresis (NE) is a predisposing factor in the development of overactive bladder (OAB).

Materials and methods

The authors recruited patients diagnosed with OAB over a period of twelve months, and those who declared a history of NE were asked additional questions regarding the features of their NE.

Results

A total of 285 patients were diagnosed with overactive bladder, and 98 (34.38%) of them had previously displayed NE symptoms that had diminished before reaching the median age of 9.83. Separation of patients by sex revealed a male majority (58.16%). Additionally, most patients had urban origins (75.51%). The median time span from remission of NE to diagnosis of OAB was 24.79 years, and the median age at which patients began to suffer was 31.80 years. Behavioral factors (smoking, alcohol consumption) and psychological and infectious factors (past history of urinary tract infection) were identified at varying degrees.

Conclusion

The presence of NE in a third of the patients who developed over time OAB and the earlier onset of OAB for these patients suggests a causal physiopathological relationship between NE and OAB. The preponderance of urban patients confirms the existence of acquired urban triggering factors of OAB (nutritious, social, or professional).

Prevalence of nocturia and fecal and urinary incontinence and the association to childhood obesity: a study of 6803 Danish school children

INTRODUCTION

Fecal and urinary incontinence are common disorders in children. Obesity and its associated comorbidities have become increasingly common, and a relation between obesity, nocturia, incontinence, and nocturnal enuresis has been suggested.

OBJECTIVE

This large scale population study aims to determine the prevalence of fecal incontinence (FI), daytime urinary incontinence (DUI), nocturnal enuresis (NE), and nocturia in children at school entry and in adolescence and to clarify whether obesity is associated to any of the aforementioned symptoms.

STUDY DESIGN

First-grade children and their parents and adolescents in the seventh to ninth grades were interviewed in relation to school nurse visits. The interview included questions on whether incontinence or nocturia were experienced at least once per month. The participants' age was recorded, and weight and height were measured. Body mass index (BMI) was calculated and age standardized by the use of BMI-standard deviation score (SDS), with reference to World Health Organization normative BMI data. Obesity was defined as BMI-SDS >2. Associations between obesity and incontinence and nocturia were quantified by odds ratio (OR).

RESULTS

Completed interview questionnaires and measurements were obtained from 4002 children (95.1%) in the child population and 2801 adolescents (84.4%) in the adolescent population. The mean age of children was 6.45 ± 0.39 years, and 4.4% were obese. Overall 11.2% reported FI, 21.8% DUI, 16.8% NE, and 31.4% experienced nocturia. Obesity was associated with FI in first-grade boys (OR 1.86 compared with normal weight). Mean age of adolescents was 13.9 ± 0.85 years, and 7.6% of adolescent boys and 5.5% of the girls were obese. Fecal incontinence was reported by 2.1% of the adolescents, 4.5% had DUI, 1.0% stated to have NE, and 32.3% reported nocturia. Obesity was significantly associated with nocturia in adolescents (OR 1.74-2.01).

DISCUSSION

The prevalence of nocturia seems constant throughout childhood and adolescent life; this has not previously been documented. Incontinence is very common at school entry, with DUI reported more frequently than enuresis by both children and adolescents. Obesity is associated with nocturia in adolescents and FI in first-grade boys, but no significant association between obesity and NE or DUI is found. Strength of this study is the very high participation rates, but the study does not reveal information on previous treatment, subtype, or severity of symptoms.

CONCLUSIONS

Incontinence is very common in children. One-third of both children and adolescents experience nocturia. Obesity is associated with FI in first-grade boys and nocturia in adolescents.

Understanding of and misconceptions around monosymptomatic nocturnal enuresis: findings from patient and physician surveys

BACKGROUND

Monosymptomatic nocturnal enuresis (MNE) is a common paediatric condition, caused by the interaction of multiple physiological mechanisms. The condition can lead to psychiatric comorbidities that are detrimental to quality of life but is under-recognised and misunderstood by society and healthcare providers.

OBJECTIVE

The objective of this study was to gather information from non-specialist physicians on their understanding of enuresis in selected European countries and from patients about the prevalence of MNE, its relationship with comorbidities and the burden of the condition.

MATERIALS AND METHODS

Between June 2016 and March 2017, physicians and patients in Alpe-Adria, Italy, Romania, Russia, Serbia and Slovakia were asked to complete different surveys on their understanding of the medical condition, its impact on the lives of patients and the prevalence of comorbidities. Surveys were translated into local languages. Survey responses were collated, and data were presented descriptively.

RESULTS

Overall, 261 physicians (paediatricians comprising nearly two-thirds) and 340 patients (approximately two-thirds were male) completed their respective surveys. Most physicians (67%) believed MNE to be caused by circadian variation of antidiuretic hormone but also mentioned psychological factors as a cause (48%). The most common explanation for MNE given by patients was psychological factors (26%), but 17% gave no explanation. For patients, difficulties related to enuresis were often behavioural (77%), including difficulties at school (61%) and with sleeping (40%). Physicians perceived low self-esteem (32%), anxiety (24%) and embarrassment (17%) as having the greatest impact on patients. There was disagreement among physicians about which discipline is best placed to treat MNE. Favoured treatments were not necessarily consistent with evidence-based guidelines, with lifestyle changes and pharmacological interventions cited most frequently.

DISCUSSION

The findings of these complementary surveys illustrate that the causes and best treatment of MNE are subject to misconceptions on the part of both the physician and the patient's caregiver. Overall, MNE is perceived as a psychological condition, rather than having a multifactorial pathophysiological basis with a substantial psychological impact. Educational initiatives for healthcare practitioners and the public should help to optimise the understanding of MNE and care of patients.

Trajectories of urinary incontinence in childhood and bladder and bowel symptoms in adolescence: prospective cohort study

OBJECTIVES

To identify different patterns (trajectories) of childhood urinary incontinence and examine which patterns are associated with bladder and bowel symptoms in adolescence.

DESIGN

Prospective cohort study.

SETTING

General community.

PARTICIPANTS

The starting sample included 8751 children (4507 men and 4244 women) with parent-reported data on frequency of bedwetting and daytime wetting for at least three of five time points (4½, 5½, 6½, 7½ and 9½ years-hereafter referred to as 4-9 years). Study children provided data on a range of bladder and bowel symptoms at age 14 (data available for 5899 participants).

OUTCOME MEASURES

Self-reported bladder and bowel symptoms at 14 years including daytime wetting, bedwetting, nocturia, urgency, frequent urination, low voided volume, voiding postponement, passing hard stools and low stool frequency.

RESULTS

We extracted 5 trajectories of urinary incontinence from 4 to 9 years using longitudinal latent class analysis: (1) normative development of daytime and night-time bladder control (63.0% of the sample), (2) delayed attainment of bladder control (8.6%), (3) bedwetting alone (no daytime wetting) (15.6%), (4) daytime wetting alone (no bedwetting) (5.8%) and (5) persistent wetting (bedwetting with daytime wetting to age 9) (7.0%). The persistent wetting class generally showed the strongest associations with the adolescent bladder and bowel symptoms: OR for bedwetting at 14 years=23.5, 95% CI (15.1 to 36.5), daytime wetting (6.98 (4.50 to 10.8)), nocturia (2.39 (1.79 to 3.20)), urgency (2.10 (1.44 to 3.07)) and passing hard stools (2.64 (1.63 to 4.27)) (reference category=normative development). The association with adolescent bedwetting was weaker for children with bedwetting alone (3.69 (2.21 to 6.17)).

CONCLUSIONS

Trajectories of childhood urinary incontinence are differentially associated with adolescent bladder and bowel symptoms. Children exhibiting persistent bedwetting with daytime wetting had the poorest outcomes in adolescence.

Factors associated with remission of primary nocturnal enuresis and changes of parental perception towards management strategies: A follow-up study

OBJECTIVE

To understand the remission rates, shifts in treatment methods used by parents, and parents' attitudes towards their children with primary nocturnal enuresis (NE).

STUDY DESIGN

A total of 408 children aged 6-12 years and diagnosed with primary nocturnal enuresis from a 2004 epidemiological study in Taiwan were enrolled. After a 5.5-year follow-up period, the remission rates of the children of each age group were evaluated, and the corresponding treatment methods were employed daily. Furthermore, the major risk factors that influenced the remission rates in these children were investigated.

RESULTS

The overall remission rate was 93.1% among all age groups, and the median age of remission was 9.9 years (95% CI 9.5-10.2 years). Comparing the previous and after results of this study, the treatment methods utilized by the parents in response to enuresis were significantly different. More parents chose combination therapy and sought medical attention as the children grew older, particularly the parents of children with severe NE. Few parents still continued to use punishment method. A Cox proportional hazards regression model revealed that girls, young children, those with low enuresis frequency, and light sleepers had higher remission rates than did their counterparts.

CONCLUSION

Parents' attitudes towards enuresis influence their choice of therapy for their children. In most cases, parents chose a combination of therapies, particularly combining limited fluid intake and regular voiding. Only 37 (9.1%) children received medicine. The older the enuretic child, the more likely the parents were to seek medical treatment for their children. Enuresis might disappear spontaneously but not always. A small proportion of children will continue to wet till adulthood. The treatment of NE at this age would be challenging. Children who were deep sleepers or affected by severe enuresis had a low probability of achieving dryness. However, girls and young children had a higher probability of achieving remission than did their counterparts.

Nocturnal enuresis: prevalence and associated LUTS in adult women attending a urogynaecology clinic

INTRODUCTION

Nocturnal enuresis (NE) is an underreported symptom with a profound impact on quality of life. The primary objective of this study was to investigate the prevalence of NE and its association with other lower urinary tract symptoms (LUTS).

METHODS

A validated pelvic floor questionnaire [electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF)] was completed by 2302 women attending a urogynaecology clinic over a 3-year period. Association between NE and overactive bladder (OAB), stress incontinence (SUI) and nocturia was assessed using logistic regression. Subgroup analysis was performed on women with NE undergoing transvaginal tape (TVT). Ethical approval was acquired from the University of Sheffield and statistical analysis performed using SPSS version 22.

RESULTS

The overall prevalence of NE reported in the cohort was 23 % (536 women). The reporting of NE was significantly associated with OAB (p < 0.005), SUI (p < 0.005) and nocturia (p < 0.005). Of 84 women undergoing TVT, 49 % reported NE preoperatively. These women reported significantly more severe symptoms of SUI and OAB (p < 0.05). Sixty percent reported improvement or cure of NE postoperatively, and this was dependent on improvement or cure of SUI (p < 0.005). The presence of NE was a negative predictor for improvement in symptoms of SUI following TVT (p = 0.037).

CONCLUSION

This study provides insight into NE, a commonly reported symptom in women attending urogynaecology clinics. To our knowledge, this is the first study to implicate stress incontinence as an important aetiological factor in women with NE. Further studies are required to better understand the aetiology of NE in adult women and relate this to management and outcome.

Advances in the management of enuresis

There are still many undiscovered facts about enuresis, even though it is a very old "symptom". It is a significant health problem with a high prevalence among children and a lower prevalence in adulthood. Many treatment guidelines have been proposed for the management of this problem. The improvement of diagnostic tools, and also treatment modalities, have had a significant impact on success rates; however, the long-term success rates need to be higher, especially in resistant cases. In this report, we summarize the advances made in the diagnosis and treatment of enuresis.

The evaluation and management of persistent nocturia

Nocturia, or waking at night to void, is a common symptom that leads to substantial morbidity. Men and women are both affected across a wide age range, such that the objective evaluation of nocturia remains a challenge, due largely to its multifactorial etiology. While for some patients, nocturia is caused by common structural conditions such as prostatic obstruction, for others it is due to a complex interplay between multiple underlying systemic diseases. For this reason, persistent nocturia merits particularly careful consideration. The purpose of this review is to describe the most recent salient research in the field of nocturia, with a particular emphasis on its evaluation and management.
