Niekontrolowane oddawanie moczu podczas snu, inaczej enureza nocna
Epidemiologia

Enureza nocna, definiowana jako niekontrolowane oddawanie moczu podczas snu, jest powszechnym zaburzeniem urologicznym w populacji pediatrycznej, z częstością występowania zmniejszającą się wraz z wiekiem: od około 82% u dzieci 2-letnich do 0,5-2% u dorosłych. Występuje częściej u chłopców (2-3-krotnie) niż u dziewcząt, a wskaźnik spontanicznej remisji wynosi około 14-15% rocznie. Ciężka enureza, charakteryzująca się codziennym moczeniem, dużą objętością moczu i objawami dziennymi, ma mniejsze prawdopodobieństwo ustąpienia, a utrzymywanie się objawów do 17. roku życia wiąże się z ryzykiem przewlekłości w dorosłości. Epidemiologia wskazuje na silny komponent genetyczny oraz współwystępowanie z innymi schorzeniami, takimi jak zaburzenia funkcji pęcherza, obturacyjny bezdech senny, zaparcia, ADHD oraz problemy behawioralne i psychologiczne.

Niekontrolowane oddawanie moczu podczas snu, inaczej enureza nocna – Epidemiologia, surveillance

Niekontrolowane oddawanie moczu podczas snu, znane również jako enureza nocna, to częsty problem wśród dzieci i, w mniejszym stopniu, także u starszej młodzieży i dorosłych. Stanowi jedno z najczęstszych zaburzeń urologicznych w populacji pediatrycznej, zarówno w podstawowej opiece zdrowotnej, jak i specjalistycznej1. Zrozumienie epidemiologii enurezji nocnej jest kluczowe dla właściwego podejścia diagnostycznego i terapeutycznego.

Częstotliwość występowania w różnych grupach wiekowych

Rozpowszechnienie enurezji nocnej jest znacznie zróżnicowane w zależności od wieku dziecka. Dane epidemiologiczne pokazują wyraźny wzorzec zmniejszania się częstości występowania wraz z wiekiem12. Badania wskazują na następujące wskaźniki częstości występowania:

  • U dzieci w wieku 2 lat – około 82%1
  • U dzieci w wieku 3 lat – około 49%1
  • U dzieci w wieku 4 lat – około 25-26%12
  • U dzieci w wieku 5 lat – około 15-25%12
  • U dzieci w wieku 6 lat – około 10-20%12
  • U dzieci w wieku 7 lat – około 5-10%12
  • U dzieci w wieku 10 lat – około 4-5%12
  • U dzieci w wieku 12 lat – u chłopców około 8%, u dziewcząt około 4%1
  • U młodzieży w wieku 15 lat – około 3%12
  • U młodzieży w wieku 18 lat – u chłopców około 1%, u dziewcząt rzadko1
  • U dorosłych – około 0,5-2%12

Szczególnie zauważalny jest spadek częstości występowania enurezji nocnej między 5. a 10. rokiem życia, gdzie odsetek dzieci moczących się w nocy zmniejsza się z około 15-25% do 4-5%12.

Różnice płciowe w występowaniu enurezji

Dane epidemiologiczne wskazują na wyraźne różnice w częstości występowania enurezji nocnej między płciami1. Moczenie nocne jest około 2-3 razy częstsze u chłopców niż u dziewcząt12. Przykładowo:

  • W wieku 7 lat: 9% chłopców i 6% dziewcząt moczy się w nocy1
  • W wieku 10 lat: 7% chłopców i 3% dziewcząt moczy się w nocy1
  • W wieku 12 lat: 8% chłopców i 4% dziewcząt doświadcza enurezji1
  • W wieku 15-16 lat: 1,6% chłopców i 0,8% dziewcząt moczy się przynajmniej raz na 3 miesiące1

Ta różnica między płciami jest najbardziej wyraźna we wczesnym dzieciństwie i zaczyna się zmniejszać po 10. roku życia1.

Spontaniczna remisja i prognozy

Istotnym aspektem epidemiologii enurezji nocnej jest wskaźnik spontanicznej remisji, czyli ustąpienia objawów bez interwencji terapeutycznej. Badania wskazują, że roczny wskaźnik spontanicznej remisji wynosi około 14-15%123. Oznacza to, że bez jakiegokolwiek leczenia około 14-15% dzieci z enureza nocną przestanie moczyć się w ciągu roku.

Prognozy dotyczące spontanicznej remisji różnią się w zależności od wieku:

  • Dzieci w wieku 5-9 lat mają wskaźnik spontanicznej remisji na poziomie około 14% rocznie1
  • Młodzież w wieku 10-17 lat ma wskaźnik spontanicznej remisji na poziomie około 16% rocznie1

Należy jednak zauważyć, że ciężka enureza (definiowana jako moczenie się każdej nocy, duża objętość moczu i współistniejące objawy dzienne) ma mniejsze prawdopodobieństwo spontanicznego ustąpienia1. Ponadto, im dłużej utrzymuje się enureza, tym mniejsze jest prawdopodobieństwo jej ustąpienia1.

Osoby, które nadal doświadczają enurezji w wieku 17 lat, prawdopodobnie będą borykać się z tym problemem przez całe życie1. Badania dotyczące długoterminowych prognoz wskazują, że około 1% osób doświadczających enurezji w dzieciństwie będzie miało ten problem również w dorosłości1.

Różnice geograficzne i międzykulturowe

Rozpowszechnienie enurezji nocnej wydaje się być podobne na całym świecie, choć brak jest standardowych badań epidemiologicznych na skalę globalną1. Enureza nocna została udokumentowana na wszystkich kontynentach – w Afryce, obu Amerykach, Azji, Australii, Europie i na Bliskim Wschodzie1.

Badania przeprowadzone w różnych krajach wykazały następujące wskaźniki rozpowszechnienia:

  • W Francji: 12,95% u dzieci w wieku 5-16 lat1
  • W Arabii Saudyjskiej: 15% u dzieci w wieku 6-11 lat1
  • W południowo-wschodniej Turcji: 14,9% u dzieci szkolnych1
  • W Arabii Saudyjskiej (region Aseer): 31,1% badanych dzieci1
  • W Egipcie (gubernatorstwo Gharbia): 14,3% u dzieci w wieku 6-12 lat1
  • W Turcji: 17,2% u dzieci w wieku szkolnym1
  • W Wielkiej Brytanii: 18,9% u dzieci w wieku szkolnym1
  • W Jemenie (Mukala): 28,6% u dzieci w szkole podstawowej1
  • W Nigerii (Zaria): 22,2% u dzieci1
  • W Jordanii (Amman): 23,8% u dzieci1
  • W Indiach: 7-12,6% u dzieci1
  • W Korei: 2,6% u osób w wieku 16-40 lat1
  • W Hongkongu: 2,3% u osób w wieku 16-40 lat1

Chociaż istnieją pewne różnice w oszacowanych wskaźnikach rozpowszechnienia między krajami i regionami, ogólne trendy w odniesieniu do wieku, płci i spontanicznej remisji wydają się być podobne12.

Czynniki ryzyka i predyktory

Liczne badania epidemiologiczne zidentyfikowały szereg czynników ryzyka i predyktorów enurezji nocnej1. Do najważniejszych należą:

  • Wywiad rodzinny: Dzieci z rodzinnym wywiadem enurezji mają znacznie wyższe ryzyko rozwoju tego zaburzenia (44-77% ryzyka)12
  • Płeć męska: Chłopcy mają około dwukrotnie wyższe ryzyko enurezji niż dziewczęta12
  • Młodszy wiek: Wyższe wskaźniki występowania obserwuje się u młodszych dzieci12
  • Niski status społeczno-ekonomiczny: Niektóre badania sugerują związek między niskim dochodem a enureza nocną1, choć nie wszystkie badania potwierdzają tę zależność2
  • Historia zakażeń układu moczowego: Dzieci z historią infekcji dróg moczowych mają wyższe ryzyko enurezji12
  • Zaburzenia oddychania podczas snu: Istnieje ścisły związek między enureza nocną a obturacyjnym bezdechem sennym12
  • Predyspozycje genetyczne: Badania wskazują na silny komponent genetyczny w przypadkach enurezji12
  • Zaburzenia koncentracji i nadpobudliwość: Dzieci z ADHD są bardziej narażone na rozwój enurezji12
  • Stres i czynniki psychologiczne: Stres, lęk, fobia ciemności, problemy rodzinne i doświadczenie nękania mogą przyczyniać się do wystąpienia enurezji12
  • Otyłość: Jest to prawdopodobny czynnik ryzyka enurezji1

W przypadku enurezji wtórnej (gdy dziecko zaczyna moczyć się po okresie co najmniej 6 miesięcy suchych nocy) dodatkowymi czynnikami ryzyka mogą być: stres, cukrzyca typu 1, zaburzenia odżywiania i inne stany psychopatologiczne12.

Współwystępowanie z innymi zaburzeniami

Badania epidemiologiczne wykazały, że enureza nocna często współwystępuje z innymi zaburzeniami i problemami zdrowotnymi1. Międzynarodowe Towarzystwo Kontroli Kontynencji u Dzieci (International Children’s Continence Society) podaje, że 20-30% dzieci z enureza ma co najmniej jedno zaburzenie zdrowia psychicznego, co stanowi około dwukrotnie wyższy wskaźnik niż u dzieci bez problemu moczenia1.

Częste zaburzenia współwystępujące obejmują:

  • Zaburzenia funkcjonowania pęcherza w ciągu dnia: Około 10-28% dzieci z enureza nocną ma również problemy z pęcherzem w ciągu dnia12
  • Łagodne dzienne objawy dolnych dróg moczowych: Występują u nawet dwóch trzecich dzieci z enureza1
  • Obturacyjny bezdech senny: Liczne badania podkreślają związek między bezdechem sennym a enureza nocną12
  • Zaparcia: Mogą nasilać objawy enurezji poprzez zwiększenie ciśnienia na pęcherz i wpływ na funkcjonowanie nerwów kontrolujących pęcherz12
  • Problemy behawioralne: Dzieci z enureza, niezależnie od jej częstotliwości, mają zwiększone wskaźniki problemów behawioralnych1
  • ADHD: Badania genetyczne wskazują, że dzieci z wieloma wariantami genetycznymi zwiększającymi ryzyko ADHD są szczególnie narażone na rozwój moczenia nocnego1

Wpływ enurezji na jakość życia

Enureza nocna ma znaczący wpływ na jakość życia dzieci i ich rodzin12. Może prowadzić do:

  • Niskiej samooceny1
  • Wtórnych problemów psychologicznych1
  • Niższych osiągnięć szkolnych12
  • Wstydu i zażenowania1
  • Izolacji społecznej i stygmatyzacji1

Ze względu na stygmatyzację związaną z enureza, wiele przypadków pozostaje niezgłoszonych, co utrudnia określenie rzeczywistego rozpowszechnienia1. Badania wskazują również, że znaczna część dzieci z enureza nie otrzymuje odpowiedniego leczenia profesjonalnego12.

Skuteczność interwencji terapeutycznych

Badania epidemiologiczne dostarczają również informacji na temat skuteczności różnych interwencji terapeutycznych stosowanych w leczeniu enurezji nocnej12.

Najskuteczniejsze metody leczenia obejmują:

  • Alarmy wybudzeniowe: Badania wykazały, że alarmy mogą pomóc około 80% dzieci osiągnąć suchość w nocy1. Duże badanie obejmujące 3257 dzieci wykazało, że około dwie trzecie dzieci używających alarmu przestało moczyć się, a połowa z tych, które wytrwały w leczeniu, pozostała sucha po zaprzestaniu stosowania alarmu1.
  • Desmopresyna: Jest to skuteczny lek, chociaż całkowicie zatrzymuje moczenie nocne u mniej niż jednej trzeciej osób. U większości pacjentów zmniejsza jednak liczbę mokrych nocy1.
  • Kombinacje terapii: Pojawiają się dowody na korzyści płynące z łączenia różnych metod leczenia enurezji1.

Z drugiej strony, badania wykazały, że powszechne strategie stosowane przez rodziców, takie jak podnoszenie dziecka w nocy, ograniczanie płynów przed snem, regularne wyjścia do toalety w ciągu dnia, nagrody i kary, nie są skuteczne w zmniejszaniu ryzyka moczenia nocnego1.

Podsumowanie danych epidemiologicznych

Enureza nocna jest częstym problemem pediatrycznym, dotykającym znaczący odsetek dzieci, z tendencją do zmniejszania się wraz z wiekiem12. Chłopcy są bardziej narażeni niż dziewczęta, a silny komponent genetyczny sugeruje rodzinne predyspozycje do tego zaburzenia12.

Chociaż spontaniczna remisja występuje u około 14-15% dzieci rocznie, ciężkie przypadki enurezji mogą utrzymywać się do wieku dorosłego12. Enureza nocna często współwystępuje z innymi zaburzeniami, takimi jak problemy z pęcherzem w ciągu dnia, obturacyjny bezdech senny i zaburzenia behawioralne12.

Dane epidemiologiczne wskazują również, że enureza ma znaczący wpływ na jakość życia dzieci i ich rodzin, powodując problemy psychologiczne, społeczne i edukacyjne12. Mimo to, wiele przypadków pozostaje niezgłoszonych i nieleczonych ze względu na stygmatyzację związaną z tym zaburzeniem12.

Skuteczne interwencje terapeutyczne, takie jak alarmy wybudzeniowe i desmopresyna, są dostępne i mogą znacząco poprawić rokowanie u dzieci z enureza nocną12. Podkreśla to znaczenie wczesnej identyfikacji i odpowiedniego leczenia tego zaburzenia1.

    Enuresis, commonly known as bedwetting, is a prevalent pediatric condition affecting approximately 15% of 5-year-old children. […] Enuresis is the most frequent urologic complaint in pediatric patients in primary care and specialty settings. […] The prevalence of enuresis is similar across cultures and varies with age, with males affected twice as often as females. […] By age 4, nearly 25% of children experience frequent bedwetting; by 5, the condition affects approximately 15% of children. […] However, due to the stigma associated with enuresis, many cases go unreported, making the true prevalence challenging to ascertain. […] The International Children’s Continence Society reports that 20% to 30% of children with enuresis have at least 1 mental health condition, approximately twice the rate of non-wetting children. […] The longer enuresis persists, the less likely it will resolve.

    In the United States, the prevalence of PE varies by age. At age 4 years, 25% of children frequently wet the bed, but by age 7 years, only 5-10% still wet the bed, and by age 10 years, fewer than 5% of children do so. […] The resolution rate of PE is approximately 15% per year; by the late teenaged years, very few patients have the condition. The resolution rate is often used as a justification for waiting and not treating PE. However, it probably is not applicable to children who wet every night and likely applies only to those children who have already started to have dry nights. […] Worldwide, the prevalence of PE seems to be approximately the same, though no standardized evaluation of the prevalence of bedwetting has been made on a global basis. […] The prevalence of enuresis gradually declines during childhood. Of children aged 5 years, 23% have enuresis. During elementary school years, 10% of 7-year-old children and 4% of 10-year-old children still experience enuresis. In adults, however, the reported prevalence of enuresis is 0.5-2%. A Korean epidemiologic study found that the overall prevalence of nocturnal enuresis in subjects aged 16-40 years was 2.6%.

    Objective: To better understand the epidemiology and behavioral correlates of bed-wetting in a nationally representative sample of children. […] Results: Bed-wetting was reported in 33% of 5-, 18% of 8-, 7% of 11-, and 0.7% of 17-years-olds. […] Conclusions: Bed-wetting in children aged 5 years and older, irrespective of its frequency, is associated with increased rates of behavior problems. Thus, although infrequent bed-wetting may not warrant medical intervention, this condition should prompt health care providers to explore behavioral issues in greater depth.

    https://www.rch.org.au/kidsinfo/fact_sheets/bedwetting/
    Bedwetting is a problem for many school-age children and their families. The good news is that for many children the problem will resolve itself over time, or can be fixed through fairly simple treatment. […] Bedwetting (also called nocturnal enuresis) is very common. As the following graph shows, almost a third of four-year-olds wet the bed. By the time they are six, only one in 10 children wet the bed, and one in 20 by age 10. Bedwetting can sometimes continue into adolescence. […] Most children have no lasting problems from bedwetting; however, many will feel embarrassed or ashamed. It is important to reassure your child that they are not the only one who wets their bed. […] Bedwetting is not often a behavioural problem and children rarely do it for attention. It is far more likely that they have little control or awareness when they are having accidents overnight.

    When PE and SE are reported, a secondary onset accounts for about 25% of cases. The prevalence of SE as a percentage of all cases increases with age. In a cohort of New Zealand children, 7.9% developed SE by the age of 10 years. […] Enuresis is more common in males. The reported prevalences of enuresis at the ages of 7 and 10 years are 9% and 7%, respectively, in boys and 6% and 3%, respectively, in girls. No racial predisposition has been documented.

    The prevalence is also higher amongst children in residential care. […] In some children, the problem can persist, with around 0.8% of girls and 1.6% of boys aged 15-16 years wetting at least once every 3 months. […] Daytime enuresis is less common and it has been estimated that it may occur in 2% of 5 year old children and this becomes less frequent with age. […] It is more common in girls than boys. […] Often accompanied by nocturnal enuresis e.g. – around 10-28% of children with bedwetting have bladder problems during the day as well.
  • #1 Bedwetting (enuresis) Statistics and Epidemiology
    http://www.dryatnight.com/bedwetting-stats.htm
    Your child has only a 15% chance of „growing out” of wetting the bed this year. […] Numerous epidemiological studies have provided insight into how common nocturnal enuresis is among children throughout the world. […] How prevalent is bedwetting? A number of epidemiological studies have been conducted internationally to identify how many children wet the bed and the results vary widely. […] Nevertheless, a number of studies (13-16) show significant prevalence in school aged children. […] The spontaneous remission rate for enuresis is estimated to be approximately 15% per year. In other words, without any intervention, only 15% of bedwetting children will become dry each year. Unfortunately, the vast majority (i.e., 85%) will still be wetting the bed a year from now if parents, or their pediatricians, choose not to intervene with treatment.
  • #1 Nocturnal enuresis – Wikipedia
    https://en.wikipedia.org/wiki/Nocturnal_enuresis
    Doctors frequently consider bedwetting as a self-limiting problem, since most children will outgrow it. Children 5 to 9 years old have a spontaneous cure rate of 14% per year. Adolescents 10 to 17 years old have a spontaneous cure rate of 16% per year. […] As can be seen from the numbers above, a portion of bedwetting children will not outgrow the problem. Adult rates of bedwetting show little change due to spontaneous cure. Persons who are still enuretic at age 17 are likely to deal with bedwetting throughout their lives. […] Studies of bedwetting in adults have found varying rates. The most quoted study in this area was done in the Netherlands. It found a 0.5% rate for 20- to 79-year-olds. A Hong Kong study, however, found a much higher rate. The Hong Kong researchers found a bedwetting rate of 2.3% in 16- to 40-year-olds.
  • #1 Nocturnal Enuresis in Children (Bed Wetting) | Doctor
    https://patient.info/doctor/nocturnal-enuresis-in-children
    Nocturnal enuresis (bedwetting) is defined by the National Institute for Health and Care Excellence (NICE) guidelines as the involuntary wetting during sleep – without any inherent suggestion of frequency of bedwetting or pathophysiology. It is considered normal up to the age of 5 years, and is common up to the age of 10 years. […] How common is nocturnal enuresis? (Epidemiology) Prevalence is reported as follows: 5-10% of 7 -year-olds. 1-2% of adolescents (15 years and older). 0.5-1.0% of adults. More prevalent in boys – 2:1 ratio, although the difference disappears after age 10. […] The majority of children who do not have a serious neurological defect or severe learning difficulties can expect to achieve nocturnal continence sooner or later. Primary enuresis without daytime symptoms resolves in approximately 5-10% of children each year. Even after dry nights have been reliably achieved, the occasional 'accident’ is still to be expected and is no cause for concern unless there is apparent regression. Those with a family history of late nocturnal continence, those with behavioural disorders and those with developmental delay will take longer. Boys tend to take longer than girls but all cases are highly variable. […] In 1% of those affected, enuresis will persist into adulthood. One study found that children with the most severe form of bedwetting are likely to persist with the problem.
  • #1 Bed-wetting (nocturnal enuresis) in children
    https://parentingscience.com/bed-wetting/
    Is bed-wetting in children — also known as “sleep enuresis” — a sign of illness? Does it indicate a child is lazy or defiant? Trying to get attention? Suffering from behavior problems? […] The answer — in most cases — is no. Kids who wet the bed aren’t lazy. Stress can contribute to enuresis, but most children who wet the bed don’t have behavior problems. […] By convention, researchers typically define nocturnal enuresis as wetting the bed in individuals who are at least 5 years old (Franco et al 2013). […] One reasonable guess is that approximately 15-20% of kids in the early grades of primary school — 6- and 7-year olds — still wet the bed from time to time. […] Studies have reported a wide range of estimates — from rates under 3% to rates exceeding 24%. […] Bed-wetting has been documented all over the world — in Africa, the Americas, Asia, Australia, Europe, and the Middle East (e.g., Fockema et al 2012; Vasconcelos et al 2017; Tai et al 2007; Sureshkumar et al 2009; Butler and Heron 2008; Mohammadi et al 2019).

[…] When the logistic regression analysis was applied to risk factors for the bed-wetting in the present study, a significant positive correlation was revealed for low age, low income, history of urinary tract infection and family history of enuresis. […] We documented that most of the children with enuresis in southeast of Turkey do not have adequate attention about enuresis and most of the enuretic children do not receive professional treatment. […] Enuresis is a pediatric public health problem and efforts at all levels should be made such as preventive, etiological and curative.

    Nocturnal enuresis is an important problem among young children living in Turkey. The purpose of this study was to determine the possible differences in the prevalence of enuresis between children in boarding school and daytime school and the association of enuresis with sociodemographic factors. […] The overall prevalence of nocturnal enuresis was 14.9%. The prevalence of nocturnal enuresis declined with age. Of the 6 year old children 33.3% still wetted their beds, while the ratio was 2.6% for 15 years-olds. […] Enuresis was reported as 18.5% among children attending day time school and among those 11.5% attending boarding school (p 0.05). Prevalence of enuresis was increased in children living in villages, with low income and with positive family history (p 0.05). […] Enuresis was more frequent among children attending daytime school when compared to boarding school. Our findings suggest that nocturnal enuresis is a common problem among school children, especially with low income, smaller age, family history of enuresis and history of urinary tract infection.
  • #1 Pattern and Risk Factors for Nocturnal Enuresis among Children in Aseer Region, Southwestern Saudi Arabia: A cross-sectional study | medRxiv
    https://www.medrxiv.org/content/10.1101/2024.10.01.24314564v1.full-text
    Nocturnal enuresis is defined as persistent bed-wetting at night beyond the age of five year old. To assess the prevalence and risk factors for nocturnal enuresis in children of the Aseer region. The study included 466 children, of which 145 (31.1%) complained of recurrent bedwetting. More than half of the children who experienced nocturnal enuresis were males (58.6%), and 31.7% were aged between 7-8 years, with a mean age of 5.9 years. Attention-deficit hyperactivity disorder, dark phobia, family troubles, and exposure to bullying were the most frequently reported risk factors. Nearly 1 out of 3 children experienced bed-wetting, which is relatively common in boys than girls. Enuresis refers to the involuntary loss of urine during sleep that occurs at least twice a week in children older than 5 years of age (or the developmental equivalent) for at least 3 months, and it is the most common urologic complaint in pediatric patients. Nocturnal enuresis is 2-3 times more common in boys than girls. About 20% of all children report occasional instances of bed-wetting until the age of 5 years, and up to 10% still have problems by 7 years of age. Bed-wetting or enuresis is categorized as primary enuresis urinary incontinence in a child who has never been dry, and secondary enuresis incontinence in a child who has been dry for at least six months. Nocturnal enuresis in children is the second most reported pediatric problem after allergic diseases. Many causative factors have been associated with bed-wetting, such as developmental differences, including the development of a child’s urinary sphincters, and diseases like diabetes and urinary tract infections. Having a global incidence of 1.428% among 6-12 years old children, the condition is troublesome for the families of these children, as it can result in considerable emotional distress and psychological consequences. The study revealed that one-third of children in our study sample complained of bed-wetting. Notably, there was significant variability in the estimated prevalence of NE among children in Saudi Arabia, ranging from 12% to 75% according to the study setting and the sampled age groups. The estimated prevalence of nocturnal enuresis in different regions of Iran is reported as 8.25% to 8.8%, compared to other studies conducted in Hong Kong, China, and Thailand. The current study also revealed that bed-wetting was more frequent among the first or last child. This phenomenon can be explained as an attention-seeking strategy adopted by older children who want to attract their parents’ attention after the birth of a younger sibling. The current study also revealed that nearly three-quarters of the children wet their bed between the age of 5-6 years, as many children have incomplete toilet training by this age and the immature nervous system is unable to fully control the bladder. Regarding the risk factors analyzed among the current study in the children resorting to bed-wetting, child-related stressors were reported in almost half of the sampled children; it included ADHD, which is a major risk factor detected in different studies, dark phobia, stress and anxiety, family troubles and parental separation, exposure to bullying, and physical abuse. We also observed that few children had a positive family history of nocturnal enuresis, one of the main risk factors, besides the water source, which was bottled water in nearly half of the sample.

    Objective The aim of this study was to determine the prevalence of nocturnal enuresis (NE) and identify its risk factors among primary school children (612 years) in Gharbia Governorate. […] NE is a challenging issue, mostly seen during childhood. However, the exact prevalence is often under-reported. Large epidemiological studies suggested the prevalence rates of 1520% among children 5 years and older. […] The prevalence of NE was 14.3%. The prevalence was slightly higher among boys than girls, with 14.8 and 13.9%, respectively, and it was more common among rural children than urban ones, with 19.1 and 7.5%, respectively. NE prevalence markedly decreases by increase in age. […] Enuresis is a pediatric public health problem that is often associated with young age. It may lead to low self-esteem, some secondary psychological problems, and low school success. Consequently, it is necessary to recommended health promotion and prevention programs that are directed toward the screening, diagnosis, and management of NE among primary school students.

    Nocturnal enuresis is a common problem among children and adolescents. Data regarding this problem in schoolchildren in Yemen are scarce. This study was aimed to determine the prevalence of nocturnal incontinence in Aden school going children, describe its severity and identify the relation between nocturnal enuresis with personal and family characteristics. The study concluded that the prevalence of nocturnal enuresis in Aden public school children and its associated factors are almost comparable with that reported in epidemiological studies from various countries. The prevalence of NE was 17.2%, which is similar to that reported in a study done in Ankara, Turkey (17.2%) and the UK (18.9%), but lower than that reported in Mukala primary school children, Hadramout, Yemen (28.6%), Zaria, Nigeria (22.2%), and Amman, Jordan (23.8%). The study finding that the prevalence of NE decreases with age is similar to most reported studies. A positive family history of enuresis was seen in 37.2% of enuretics. Factors associated with NE included daytime enuresis and tea drinking habits. Stressful events occurred twice more frequently in the previous 6 months in enuretic students.

    Bedwetting is the most prevalent of chronic childhood disorders (Hicks and Clark, 1999), and families who are affected may feel isolated and stigmatised. This article discusses the nature of bedwetting – including definitions and epidemiology – treatment strategies and the role of the health visitor and practice nurse in managing this problem. […] Nocturnal enuresis affects at least 500,000 children between the ages of five and 11 in the UK each year. The prevalence of the condition among the entire child population is broken down in Box 1. […] Genetics – Research has revealed a strong genetic link in cases of enuresis (vonGontard, 1999). The associated genes have been isolated to 8q, 12q and 13q on the human genome. These sites all appear to be involved in gaining bladder control. […] The problem of bedwetting is often overlooked or ignored, yet it can cause the child great and unnecessary embarrassment. There is often a solution, and the practice nurse or health visitor is often the first health professional the family will speak to for advice on the matter.

    Medications are available on prescription from your family doctor. […] Desmopressin is the best medication and is taken as a tablet, a nose spray or a wafer that dissolves on the tongue (melt). It works by concentrating your urine so that there is not such a large volume to cope with.

It does not cure the problem when you stop taking it, the bed-wetting often recurs but it is safe to take it over a long period. […] Tolterodine and oxybutynin calm overactive bladder muscle. They may be helpful if you have daytime wetting as well as bed-wetting, and have to rush to get to the toilet (urgency). They can cause side effects, such as dry mouth and constipation, but these can be minimized by taking the medication at night.

    Nocturnal enuresis (bedwetting) is defined by the National Institute for Health and Care Excellence (NICE) guidelines as the involuntary wetting during sleep – without any inherent suggestion of frequency of bedwetting or pathophysiology. It is considered normal up to the age of 5 years, and is common up to the age of 10 years. […] How common is nocturnal enuresis? (Epidemiology) Prevalence is reported as follows: 5-10% of 7 -year-olds. 1-2% of adolescents (15 years and older). 0.5-1.0% of adults. More prevalent in boys – 2:1 ratio, although the difference disappears after age 10. […] The majority of children who do not have a serious neurological defect or severe learning difficulties can expect to achieve nocturnal continence sooner or later. Primary enuresis without daytime symptoms resolves in approximately 5-10% of children each year. Even after dry nights have been reliably achieved, the occasional 'accident’ is still to be expected and is no cause for concern unless there is apparent regression. Those with a family history of late nocturnal continence, those with behavioural disorders and those with developmental delay will take longer. Boys tend to take longer than girls but all cases are highly variable. […] In 1% of those affected, enuresis will persist into adulthood. One study found that children with the most severe form of bedwetting are likely to persist with the problem.

At age 4 years, 25% of children frequently wet the bed, but by age 7 years, only 5-10% still wet the bed, and by age 10 years, fewer than 5% of children do so. […] The resolution rate of PE is approximately 15% per year; by the late teenaged years, very few patients have the condition. The resolution rate is often used as a justification for waiting and not treating PE. However, it probably is not applicable to children who wet every night and likely applies only to those children who have already started to have dry nights. […] Worldwide, the prevalence of PE seems to be approximately the same, though no standardized evaluation of the prevalence of bedwetting has been made on a global basis. […] The prevalence of enuresis gradually declines during childhood. Of children aged 5 years, 23% have enuresis.

    Nocturnal enuresis is defined as persistent bed-wetting at night beyond the age of five year old. To assess the prevalence and risk factors for nocturnal enuresis in children of the Aseer region. The study included 466 children, of which 145 (31.1%) complained of recurrent bedwetting. More than half of the children who experienced nocturnal enuresis were males (58.6%), and 31.7% were aged between 7-8 years, with a mean age of 5.9 years. Attention-deficit hyperactivity disorder, dark phobia, family troubles, and exposure to bullying were the most frequently reported risk factors. Nearly 1 out of 3 children experienced bed-wetting, which is relatively common in boys than girls. Enuresis refers to the involuntary loss of urine during sleep that occurs at least twice a week in children older than 5 years of age (or the developmental equivalent) for at least 3 months, and it is the most common urologic complaint in pediatric patients. Nocturnal enuresis is 2-3 times more common in boys than girls. About 20% of all children report occasional instances of bed-wetting until the age of 5 years, and up to 10% still have problems by 7 years of age. Bed-wetting or enuresis is categorized as primary enuresis urinary incontinence in a child who has never been dry, and secondary enuresis incontinence in a child who has been dry for at least six months. Nocturnal enuresis in children is the second most reported pediatric problem after allergic diseases. Many causative factors have been associated with bed-wetting, such as developmental differences, including the development of a child’s urinary sphincters, and diseases like diabetes and urinary tract infections. Having a global incidence of 1.428% among 6-12 years old children, the condition is troublesome for the families of these children, as it can result in considerable emotional distress and psychological consequences. The study revealed that one-third of children in our study sample complained of bed-wetting. Notably, there was significant variability in the estimated prevalence of NE among children in Saudi Arabia, ranging from 12% to 75% according to the study setting and the sampled age groups. The estimated prevalence of nocturnal enuresis in different regions of Iran is reported as 8.25% to 8.8%, compared to other studies conducted in Hong Kong, China, and Thailand. The current study also revealed that bed-wetting was more frequent among the first or last child. This phenomenon can be explained as an attention-seeking strategy adopted by older children who want to attract their parents’ attention after the birth of a younger sibling. The current study also revealed that nearly three-quarters of the children wet their bed between the age of 5-6 years, as many children have incomplete toilet training by this age and the immature nervous system is unable to fully control the bladder. Regarding the risk factors analyzed among the current study in the children resorting to bed-wetting, child-related stressors were reported in almost half of the sampled children; it included ADHD, which is a major risk factor detected in different studies, dark phobia, stress and anxiety, family troubles and parental separation, exposure to bullying, and physical abuse. We also observed that few children had a positive family history of nocturnal enuresis, one of the main risk factors, besides the water source, which was bottled water in nearly half of the sample.

    This Clinical Policy Bulletin addresses enuresis. […] More than 5 % of 7-year old children and 0.5 % of adults experience primary nocturnal enuresis. […] Primary NE resolves spontaneously in most children over time. […] The enuretic alarm is most effective in patients with the highest frequency of NE. […] The International Children’s Continence Society’s guideline on the evaluation and treatment of MNE noted that the mainstays of primary therapy are bladder advice, the enuresis alarm and/or desmopressin. […] A total of 326 toilet trained children 3 to 15 years old were included, with 257 in the tonsillectomy group and 69 in the control group. […] The authors concluded that SDB in children is associated with nocturnal enuresis. […] A total of 14 studies were reviewed. […] The authors concluded that adenotonsillectomy is associated with a significant improvement in enuresis in children with SDB.

    In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis – commonly known as bedwetting or nighttime incontinence. […] Researchers have long known that nighttime incontinence is a highly heritable condition. […] In collaboration with the Danish research project iPSYCH and a team of international colleagues, researchers from Aarhus University have for the first time identified genetic variants that increase the risk of bedwetting. […] The study also shows that commonly occurring genetic variants can explain up to one-third of the genetic risk of bedwetting. […] The study also shows that children with many genetic variants that increase the risk of ADHD are particularly vulnerable to developing bedwetting. […] As the study is a first-time study, the researchers also examined more than 5,500 people from Iceland, where they found that the same genetic variants also appear to increase the risk of nocturnal enuresis. […] The researchers hope to be able to further clarify the causes of nocturnal enuresis.
  • #2 Bed-wetting (nocturnal enuresis) in children
    https://parentingscience.com/bed-wetting/
    Researchers recognize a number of possible causes. The most common include: reduced bladder capacity, and/or an overactive bladder; too much urine production at night (caused by a developmental delay in a child’s nighttime release of anti-diuretic hormones); failure to awaken in response to the sensation of a full bladder; urinary tract infection; constipation; obstructive sleep apnea. […] Secondary nocturnal enuresis (SNE) has also been linked with stress (Caldwell et al 2005), anorexia (Kanbur et al 2010; Kanbur et al 2011), and the onset of type 1 diabetes (Roche et al 2005). […] This is called primary noctural enuresis (PNE), and it too can be linked with urinary tract infections, constipation, and stress (Robson et al 2005). […] Enuresis is more common in children who suffer from breathing abnormalities, like obstructive sleep apnea (Brown et al 2009; Kovacevic et al 2014; Jönson et al 2017; Wada et al 2018; Bascom et al 2019).

    Enuresis, or bedwetting, is defined as discrete episodes of urinary incontinence during sleep in children aged 5 and older, and is commonly encountered in paediatric practice. […] The prevalence is 15% at age 5 years, 10% by age 7, and 5% by age 10. […] Untreated enuresis has an estimated prevalence into adulthood of up to 2%. […] Enuresis can have significant negative impacts on child health and family life. […] Distinguishing monosymptomatic from non-monosymptomatic enuresis requires active screening. […] Mild daytime lower urinary tract symptoms (LUTS) are common, affecting up to two-thirds of enuretic children. […] When LUTS are present (i.e., in non-monosymptomatic enuresis), LUTS should be addressed first. […] Improvement in LUTS can improve enuresis secondarily. […] Conversely, enuresis treatment is less likely to succeed in the presence of unrecognized and untreated LUTS.

    Background: Enuresis, which is frequently diagnosed amongst school-children, is an important psychosocial problem for both parents and children. […] Objectives: In the present study, we aimed to determine the prevalence and associated factors of enuresis in Saudi children in Hail, and to identify common methods used for its management. […] Results: Of the 700 questionnaires distributed, 652 (93.14%) were completed. The overall prevalence of nocturnal enuresis was 22.7% (n = 148). Female gender, young age, history of enuresis among parents or siblings, deep sleep and history of urinary tract infections and other social and psychological problems were associated factors with enuresis. […] Conclusion: Our results with enuresis prevalence and associated factors were comparable to other epidemiologic studies from various countries. Furthermore, we demonstrated that families in Hail do not pay sufficient attention to enuresis and most of enuretic children do not receive professional treatment.

    Bedwetting alarms are thought to be the most useful and successful first-step to treat bedwetting. Research has shown these alarms will help 80 per cent of children to become dry, and most children will then stay dry. […] Bedwetting alarms are considered the most successful first step to treat bedwetting. Medication is an option if alarms have not helped.

    Bedwetting is the most prevalent of chronic childhood disorders (Hicks and Clark, 1999), and families who are affected may feel isolated and stigmatised. This article discusses the nature of bedwetting – including definitions and epidemiology – treatment strategies and the role of the health visitor and practice nurse in managing this problem. […] Nocturnal enuresis affects at least 500,000 children between the ages of five and 11 in the UK each year. The prevalence of the condition among the entire child population is broken down in Box 1. […] Genetics – Research has revealed a strong genetic link in cases of enuresis (vonGontard, 1999). The associated genes have been isolated to 8q, 12q and 13q on the human genome. These sites all appear to be involved in gaining bladder control. […] The problem of bedwetting is often overlooked or ignored, yet it can cause the child great and unnecessary embarrassment. There is often a solution, and the practice nurse or health visitor is often the first health professional the family will speak to for advice on the matter.

    Doctors frequently consider bedwetting as a self-limiting problem, since most children will outgrow it. Children 5 to 9 years old have a spontaneous cure rate of 14% per year. Adolescents 10 to 17 years old have a spontaneous cure rate of 16% per year. […] As can be seen from the numbers above, a portion of bedwetting children will not outgrow the problem. Adult rates of bedwetting show little change due to spontaneous cure. Persons who are still enuretic at age 17 are likely to deal with bedwetting throughout their lives. […] Studies of bedwetting in adults have found varying rates. The most quoted study in this area was done in the Netherlands. It found a 0.5% rate for 20- to 79-year-olds. A Hong Kong study, however, found a much higher rate. The Hong Kong researchers found a bedwetting rate of 2.3% in 16- to 40-year-olds.

    The overall prevalence of enuresis was found to be 12.95% in children aged 5-16 years from France and 15% in children aged 6-11 years from Saudi Arabia. […] We found the prevalence of enuresis to be 14.9% in a county, southeast of Turkey. […] Enuresis was more frequent among children attending the day-time school than the boarding school, although by logistic regression analysis no correlation was found. […] When the logistic regression analysis was applied to risk factors for the bed-wetting in the present study, a significant positive correlation was revealed for low age, low income, history of urinary tract infection and family history of enuresis. […] We documented that most of the children with enuresis in southeast of Turkey do not have adequate attention about enuresis and most of the enuretic children do not receive professional treatment. […] Enuresis is a pediatric public health problem and efforts at all levels should be made such as preventive, etiological and curative.

    Medications are available on prescription from your family doctor. […] Desmopressin is the best medication and is taken as a tablet, a nose spray or a wafer that dissolves on the tongue (melt). It works by concentrating your urine so that there is not such a large volume to cope with. Although it stops bed-wetting completely only in less than one-third of people, most find it reduces the number of wet nights. It does not cure the problem when you stop taking it, the bed-wetting often recurs but it is safe to take it over a long period. […] Tolterodine and oxybutynin calm overactive bladder muscle. They may be helpful if you have daytime wetting as well as bed-wetting, and have to rush to get to the toilet (urgency). They can cause side effects, such as dry mouth and constipation, but these can be minimized by taking the medication at night. If desmopressin has not worked, they may be useful in combination with imipramine, but usually under the supervision of a specialist. […] Imipramine is a medication that helps the bladder to hold more urine. It used to be popular, but is now used only if desmopressin has not helped. It has some side effects and is dangerous if too much is taken, so is usually only prescribed by a specialist.
