OBJECTIVE: To investigate the role of autonomic nervous system in subpopulations of children with enuresis.
METHODS: We included 35 children with enuresis, divided in children with (17) and without nocturnal polyuria (18) and 43 healthy controls. For all participants hormones and neurotransmitters were measured. Patients and controls wore a sleep tracker device and children with enuresis underwent a 24 h blood pressure monitoring, nocturnal urine output measurement and uroflowmetry.
RESULTS: Children with enuresis had lower than controls copeptin and aldosterone, with the latter being more prominent in patients without nocturnal polyuria. Dopamine was lower in patients without nocturnal polyuria compared with patients with nocturnal polyuria. Children without polyuria experienced episodes only during NREM sleep, whereas in children with polyuria episodes occurred in both REM and NREM sleep. Children with enuresis experienced a non-dipping phenomenon during sleep which was more prominent in the group without polyuria.
CONCLUSIONS: In patients with nocturnal polyuria, nocturnal enuresis is associated with sympathetic hyperactivity which results in pressure polyuria and significantly lower systolic dipping during sleep. On the contrary, in children without nocturnal polyuria, it is mostly associated with bladder overactivity due to parasympathetic overstimulation as demonstrated by the NREM-related enuretic episodes and the lower aldosterone and dopamine levels.

Background: Nocturnal Enuresis (NE) is a common problem among children that is stressful for both the child and adults. There is a lack of adults\' knowledge and awareness of the NE condition. Objective: This study aimed to evaluate the adults\' knowledge and awareness of NE in Medina City, Saudi Arabia. Method: A cross-sectional observational study was conducted among adults in Medina through September and October 2023, using a questionnaire composed of socio-demographic characteristics and adults\' knowledge and awareness of NE. A statistical analysis was performed using SPSS software. Results: The study was conducted among 553 adults in Medina, with a mean (standard deviation [SD]) age of 37.69 (10.775). Most participants (94.8%) were Saudi nationals, of which 84.4% were females, 76.3% were married, and 97.1% were urban residents with university degrees (80.3%). The mean (SD) total score of knowledge and awareness was 4.69 (1.783) out of 9 and 6.49 (2.167) out of 12, respectively. Being female (p < 0.001), with a university degree (p = 0.002), and knowing about enuresis in children (p = 0.011) are significant factors affecting adults\' knowledge with higher scores than others. Conclusions: An inadequate knowledge and awareness level of NE in children was revealed among adults living in Medina City, Saudi Arabia. These results emphasize the need for targeted educational campaigns to enhance adults\' knowledge and awareness of enuresis.

BACKGROUND: Lower urinary tract symptoms (LUTS) and nocturnal enuresis (NE) are complex conditions requiring a long-term follow-up. Telemedicine is an emerging technological tool in the surgical field, and its availability exponentially grew during the COVID-19 pandemic, expanding its application fields, optimizing technical aspects, reducing costs, and ensuring high-quality standards. This work describes our experience with telemedicine in a Division of Pediatric Urology for the follow-up of enuresis and LUTS.
METHODS: A retrospective analysis of our telemedicine preliminary experience was conducted at Regina Margherita Children\'s Hospital in Turin, Italy. This study included all the patients aged <18 years who were monitored for enuresis and LUTS through telemedicine between September 1, 2021 and July 31, 2023. Clinical data and outcomes were analyzed, and patients and families were asked to voluntary fill an evaluation questionnaire on their satisfaction. Additionally, we focused on the post COVID-19 period, between September 2022 and July 2023, analyzing the data of two different patients\' populations: the first one (G1) of patients choosing telemedicine outpatients visits (TOVs) and the second one (G2) of those choosing a face-to-face visit.
RESULTS: One hundred five patients were enrolled. One hundred sixty-two TOVs were performed. The median age at first visit was 9.7±0.66 years (range 7-16 years). Diagnosis were: 77/105 (67%) NE and 28/105 (33%) LUTS. The average referred distance between the patients\' residence and the hospital was 46.35±129.37 km (range 2-1300 kilometers) and the time taken to overcome it was 44.21±77.29 minutes (range 10-780 minutes). In 64/105 cases (61%) the follow-up was interrupted for total healing or symptoms resumption. Only two cases (2%) required the conversion to an in-person ambulatory consult, due to a social-linguistic barrier. 146/162 families (90%) filled the survey questionnaire at the end of each TOV, reporting in 94% of cases a high satisfaction level. In the comparative statistical analysis of the two patient groups, G1 (52 telemedicine office visits, [TOVs]) vs. G2 (25 face-to-face visits), the average referred distance was 17.78±7.98 km (range: 5-35 km) for G1, contrasting with 7.04±3.35 km (range: 2.5-14 km) for G2 (P=0.00001). Additionally, the waiting time before the visit was 3.96±2.90 minutes (range: 0-10 minutes) for G1, in contrast to 26.52±11.22 minutes (range: 5-44 minutes) for G2 (P=0.00001). Furthermore, a higher compliance with behavioral or pharmacological indications was observed in the G1 group, exhibiting lower adherence in only 12 out of 52 cases compared to 14 out of 25 cases in G2 (P=0.0091).
CONCLUSIONS: Telemedicine is a proper solution and an effective tool to manage the therapeutic follow-up of NE and LUTS, ensuring suitable quality standards and reducing social costs, such as the loss of working days and transport costs. The implementation and complete integration of its use into the healthcare system should be the goals to pursue in order to take full advantage of all its potentials.

UNASSIGNED: Nocturnal enuresis is associated with severe social and psychological problems that affect one\'s self-esteem, later in life, harmed adolescent and adult life, emotional stress on the family, and poor school performance. Moreover, enuresis children may cause panic attacks, mood disorders, and depression. This study aims to assess the prevalence and associated factors of nocturnal enuresis among children aged 5-14 years in Gondar city, Northwest Ethiopia, 2023.
UNASSIGNED: A community-based, cross-sectional study was conducted from April 1, 2023, to May 30, 2023. A stratified multistage sampling technique was used to select study subject from kebeles in Gondar city. The data were collected by using a structured, interviewer-administer Questionnaire. The data were entered using EPI DATA version 4.6.02 software, and processed,and analyzed using the statistical package for the social sciences (SPSS) version 25. All variables with P ≤ 0.25 in the bivariate analysis were included in the final model of multivariate analysis. The multivariate binary logistic regression was used to assess the association between the independent and outcome variable. The direction and strength of statistical association were measured with an adjusted odds ratio along with 95% CI and a P-value <0.05 was considered statistically significant.
UNASSIGNED: The overall prevalence of nocturnal enuresis among children aged 5-14 years was 162 (22.2%). The findings showed that being boys [AOR = 0.54; 95% CI (0.31, 0.93)], child and no toilet training practices [AOR = 2.50; 95% CI (1.02, 6.15)], Having no caffeine [AOR = 0.16; 95% CI (0.09, 0.29)], and exposure to stressful events [AOR = 20; 95% CI (11.12, 33.34)] had a significant association with nocturnal enuresis, p-value <0.05.
UNASSIGNED: In this study, the prevalence of nocturnal enuresis children age 5-14 years was higher than that in previous studies. Sex of child, toilet training practices, caffeine c before bed, and presences of stressful event were a significant predictor of nocturnal enuresis.

Nocturnal enuresis (NE) is involuntary bedwetting during sleep, typically appearing in young children. Despite the potential benefits of the long-term home monitoring of NE patients for research and treatment enhancement, this area remains underexplored. To address this, we propose NEcare, an in-home monitoring system that utilizes wearable devices and machine learning techniques. NEcare collects sensor data from an electrocardiogram, body impedance (BI), a three-axis accelerometer, and a three-axis gyroscope to examine bladder volume (BV), heart rate (HR), and periodic limb movements in sleep (PLMS). Additionally, it analyzes the collected NE patient data and supports NE moment estimation using heuristic rules and deep learning techniques. To demonstrate the feasibility of in-home monitoring for NE patients using our wearable system, we used our datasets from 30 in-hospital patients and 4 in-home patients. The results show that NEcare captures expected trends associated with NE occurrences, including BV increase, HR increase, and PLMS appearance. In addition, we studied the machine learning-based NE moment estimation, which could help relieve the burdens of NE patients and their families. Finally, we address the limitations and outline future research directions for the development of wearable systems for NE patients.

OBJECTIVE: Desmopressin is well accepted as first-line medical therapy for enuresis. If ineffective, combination therapy of desmopressin + oxybutynin or desmopressin + imipramine has been used. This study assessed the efficacy of adjunct therapy with either imipramine or oxybutynin in the management of enuresis patients who failed desmopressin treatment.
METHODS: A retrospective chart review of our database for patients with enuresis was performed. Patients who were prescribed desmopressin, oxybutynin, and imipramine over 14 years for enuresis were included. Two cohorts of patients were examined; group OXY was treated with desmopressin and oxybutynin, and group IMP received desmopressin and imipramine. Pretreatment measurement of Vancouver Symptom Scores (VSS) were used to compare groups using the VSS question \"I wet my bed at night\" where 4: every night, 3: 4-5 nights per week, 2: 1-2 nights per week, 1: 3-4 nights per month, and 0: never. International Children\'s Continence Society (ICCS) criteria for continence success was utilized to determine outcomes.
RESULTS: 2521 patients prescribed one of the 3 medications were identified. Among them, 81 patients (mean age: 10.5 ± 2.8 years) received combination therapy. Of which, 55 were male and 26 female. Specifically, 58 were prescribed both desmopressin and imipramine (group IMP), 23 desmopressin and oxybutynin (group OXY), and 4 transitioned from OXY to IMP. Mean pretreatment VSS showed no difference between groups. Both groups experienced minimal drops in wet nights with desmopressin alone. A comparison revealed that group IMP reduced wet nights significantly more than group OXY (VSS wet night score 0.7 ± 1.2 vs. 2.3 ± 1.1 respectively, p < 0.0001). Non-intent-to-treat complete response rate was 68% vs 5% (OR = 42.5, p < 0.001) (IMP vs. OXY respectively). Intent-to-treat response rates were 58%.
CONCLUSIONS: Although first-line desmopressin treatment for enuresis is effective, it does not work for all patients, and many parents and children desire nighttime dryness. Clinicians have combined desmopressin with oxybutynin or imipramine for improved results, but research comparing these modalities is scarce. Our study suggests that the desmopressin and imipramine combination is superior at reducing nights wet compared to desmopressin and oxybutynin, attributed to imipramine\'s probable central mechanism rather than its secondary anticholinergic properties. Limitations include a modest sample size, retrospective design, and subjective responses to the Vancouver questionnaire.
CONCLUSIONS: A combination of desmopressin and imipramine was more effective in reducing wet nights and had a complete response rate that was 42.5 times greater than desmopressin and oxybutynin.

UNASSIGNED: To outline the prevalence of vitamin D and vitamin B12 deficiencies in enuretic children.
UNASSIGNED: An analytical descriptive study was conducted on enuretic children who were followed up at the outpatient clinic for nocturnal enuresis at the Children\'s Hospital, Cairo University. Sociodemographic and clinical data were recorded. The levels of vitamin D and vitamin B12 were assessed and correlated with the severity of enuresis.
UNASSIGNED: Two hundred and eighty-eight children were enrolled. Insufficiency of Vitamin D predominated (n = 139; 48.3%). Vitamin D deficiency was present in 31.3%, n = 90 and it was normal in 20.5%, n = 59). Vitamin B12 deficiency was observed in 25% of the studied children, n = 72). The one-sample Wilcoxon signed-rank test was significant for both vitamins (P value =0.001). Vitamin D showed a stronger inverse correlation with the number of enuresis episodes per day than vitamin B12 (-0.680 vs. -0.219 respectively). A cut-off of 13.7 ng/ml for vitamin D was detected, below which the child was predicted to have failed dry nights. Using multivariate logistic regression, higher vitamin D levels and behavioural treatment coexistence were significant protective factors for the absence of dry nights.
UNASSIGNED: Low levels of vitamin D and B12 were detected in children with primary nocturnal enuresis, which could be considered a burden on the clinical severity of enuresis.
What is already known on this topic?Children with Primary Nocturnal Enuresis may have vitamin D and vitamin B12 abnormalities as deficienciesWhat does this study add?Vitamin D insufficiency may be the most prevalent vitamin D abnormality in children with primary nocturnal enuresis. Vitamin D insufficiency may be more common in children with severe enuresis than vitamin B12 deficiency.How might this study affect research, practice, or policy?This study may invite further research to examine the possible use of vitamin D and vitamin B12 as potential adjuvant therapies for children with Primary Nocturnal Enuresis.

BACKGROUND: Nocturnal enuresis, or bedwetting, is a prevalent and emotionally challenging condition that has a significant impact on the behavior, psychological well-being, and social lives of school-aged children.
OBJECTIVE: This study aimed to assess the effectiveness of bladder retraining programme on bedwetting frequency and relapse rate among children with nocturnal enuresis.
METHODS: The study was conducted in two phases. The Phase I included a survey questionnaire to identify the prevalence of nocturnal enuresis among school children studying in Grade I to Grade X of 3 selected schools in Nashik, India. Out of 2150 prevalence questionnaires, 1900 filled in questionnaires were received back. 226 children were found to be positive for monosymptomatic nocturnal enuresis. A total of 160 children were selected from which 80 samples were included in experimental group and 80 were in control group. A three-step bladder retraining program was provided for parents and children in the experimental group. The parents and children from experimental group were called on the 15th day to reinforce the interventions. Posttests were conducted at 1st month (Posttest I), 3rd month (Posttest II), and 6th month (Posttest III/Relapse) for both experimental and control group.
RESULTS: The total prevalence of nocturnal enuresis among 1900 school age children aged 6 years-15 years is found to be 11.89%. Out of the 226 enuretic children, majority 101 (44.69%) wet their beds 1-3 times per week while 48 (21.23%) children wet their beds Every night. Comparison of bedwetting frequency in both groups during Pretest, Posttest I, Posttest II and Posttest III using chi-square test showed that: In pretest there was no significant difference between children in experimental and control group as indicated by the non-significant P value 0.43. Whereas in posttest I, II & III, P value 0.001 indicates highly significant difference in bedwetting frequency of children in both the groups. Children in experimental group had a relapse rate of 3.75% and 100% relapse was observed in control group during posttest III (at 6th month).
CONCLUSIONS: The study findings revealed a statistically significant reduction in bedwetting frequency within the experimental group (p = 0.001), contrasting with the control group\'s non-significant change (p = 0.17). Additionally, the relapse rate was markedly lower in the experimental group (3.75%) compared to the control group (100%). This aligns with Garcia-Fernandez and Petros\' (2020) findings, where a squatting-based pelvic floor rehabilitation method demonstrated a significant reduction in bedwetting frequency, curing 86% of children. Van Kampen et al.\'s (2009) study also supported the efficacy of pelvic floor muscle training in reducing relapse rates, providing further validation for the current study\'s findings.
CONCLUSIONS: The 3 step bladder retraining programme was found to be very effective in reducing the bedwetting frequency and relapse rate among children. This study provides evidence supporting effectiveness of such tailored bladder retraining interventions in managing monosymptomatic nocturnal enuresis in school-aged children.

UNASSIGNED: Nocturnal enuresis can be frustrating for children and their families as the child ages. Our aim is to evaluate urine aquaporin 2 (AQP-2) as a noninvasive biomarker of water balance in children with primary monosymptomatic nocturnal enuresis (PMNE).
UNASSIGNED: The study included 90 children; sixty-eight children suffering from PMNE aged (9.57 ± 2.16) years and 22 healthy children with good toilet control, matched sex and age. All enuretic children were subjected to complete history taking, clinical evaluation, and bed wetting diary. Serum arginine vasopressin (AVP) and urine AQP-2 were tested in the morning (at 9-11 am) and evening (at 9-11 pm). Blood urea, creatinine, Na, glucose, urine osmolality, Ca/Cr, Alb/Cr and specific gravity were tested simultaneously.
UNASSIGNED: Serum AVP, urine AQP-2, and urine osmolality were statistically lower in patients than controls. Patients had a significantly lower level of night serum AVP concentrations, urine AQP-2, and urine osmolality than the corresponding morning level. Urine AQP-2 was significantly correlated with urine osmolality (p < 0.05). AQP-2 had a sensitivity of 90% and a specificity of 70%. However, no statistically significant correlation was found between serum AVP and urine AQP-2.
UNASSIGNED: Primary monosymptomatic nocturnal enuresis in children could be associated with reduction of urine excretion of AQP-2 at night. Urine AQP-2 is significantly correlated with urine osmolality. Therefore, it may be a noninvasive biomarker of hydration status in children with PMNE, with good sensitivity and specificity.
