Impact

A review of medical literature shows doctors consistently stressing that a bedwetting child is not at fault for the situation. Many medical studies state that the psychological impacts of bedwetting are more important than the physical considerations. "It is often the child's and family members' reaction to bedwetting that determines whether it is a problem or not."


Self-esteem

Whether bedwetting causes low self-esteem remains a subject of debate, but several studies have found that self-esteem improved with management of the condition. Children questioned in one study ranked bedwetting as the third most stressful life event, after "parental war of words", divorce and parental fighting. Adolescents in the same study ranked bedwetting as tied for second with parental fighting. Bedwetters face problems ranging from being teased by siblings, being punished by parents, the embarrassment of still having to wear diapers, and being afraid that friends will find out. Psychologists report that the amount of psychological harm depends on whether the bedwetting harms self-esteem or development of social skills. Key factors are: * How much the bedwetting limits social activities like sleep-overs and campouts * The degree of the social ostracism by peers * (Perceived) Anger, punishment, refusal and rejection by caregivers along with subsequent guilt * The number of failed treatment attempts * How long the child has been wetting


Behavioral impact

Studies indicate that children with behavioral problems are more likely to wet their beds. For children who have developmental problems, the behavioral problems and the bedwetting are frequently part of/caused by the developmental issues. For bedwetting children without other developmental issues, these behavioral issues can result from self-esteem issues and stress caused by the wetting. As mentioned below, current studies show that it is very rare for a child to intentionally wet the bed as a method of acting out.


Punishment for bedwetting

Medical literature states, and studies show, that punishing or shaming a child for bedwetting will frequently make the situation worse. It is best described as a downward cycle, where a child punished for bedwetting feels shame and a loss of self-confidence. This can cause increased bedwetting incidents, leading to more punishment and shaming. In the United States, about 25% of enuretic children are punished for wetting the bed. In Hong Kong, 57% of enuretic children are punished for wetting. Parents with only a grade-school level education punish bedwetting children at twice the rate of high-school- and college-educated parents. In

. This is motivated in part by a desire to publicly embarrass the child into compliance, as neighbors would recognize why the child was knocking on their door.


Families

Parents and family members are frequently stressed by a child's bedwetting. Soiled linens and clothing cause additional laundry. Wetting episodes can cause lost sleep if the child wakes and/or cries, waking the parents. A European study estimated that a family with a child who wets nightly will pay about $1,000 a year for additional laundry, extra sheets, diapers, and mattress replacement. Despite these stressful effects, doctors emphasize that parents should react patiently and supportively.


Sociopathy

Bedwetting does ''not'' indicate a greater possibility of being a sociopath, as long as caregivers do not cause trauma by shaming or punishing a bedwetting child. Bedwetting was part of the Macdonald triad, a set of three behavioral characteristics described by John Macdonald in 1963. The other two characteristics were firestarting and
animal abuse Cruelty to animals, also called animal abuse, animal neglect or animal cruelty, is the infliction of suffering or harm by humans upon animals, either by omission (neglect) or by commission. More narrowly, it can be the causing of harm or suffe ...
. Macdonald suggested that there was an association between a person displaying all three characteristics, then later displaying sociopathic criminal behavior. Up to 60% of multiple murderers, according to some estimates, wet their beds post-adolescence. Enuresis is an "unconscious, involuntary ..act". Bedwetting can be connected to past emotions and identity. Children under substantial stress, particularly in their home environment, frequently engage in bedwetting, in order to alleviate the stress produced by their surroundings. Trauma can also trigger a return to bedwetting (secondary enuresis) in both children and adults. It is not bedwetting that increases the chance of criminal behavior, but the associated trauma. Parental cruelty can result in "homicidal proneness".

of NE is not fully understood, although there are three common causes: excessive urine volume, poor sleep arousal, and bladder contractions. Differentiation of cause is mainly based on patient history and fluid charts completed by the parent or carer to inform management options. Bedwetting has a strong genetic component. Children whose parents were not enuretic have only a 15% incidence of bedwetting. When one or both parents were bedwetters, the rates jump to 44% and 77% respectively. These first two factors (aetiology and genetic component) are the most common in bedwetting, but current medical technology offers no easy testing for either cause. There is no test to prove that bedwetting is only a developmental delay, and
genetic testing Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or ...
offers little or no benefit. As a result, other conditions should be ruled out. The following causes are less common, but are easier to prove and more clearly treated: In some bedwetting children there is no increase in ADH (antidiuretic hormone) production, while other children may produce an increased amount of ADH but their response is insufficient. * People with reported bedwetting issues are 2.7 times more likely to be diagnosed with

can lead to bedwetting. During sleepwalking, the sleepwalker may think they are in another room. When the sleepwalker urinates during a sleepwalking episode, they usually think they are in the bathroom, and therefore urinate where they think the toilet should be. Cases of this have included opening a closet and urinating in it; urinating on the sofa, and simply urinating in the middle of the room. * Stress is a cause of people who return to wetting the bed. Researchers find that moving to a new town, parent conflict or divorce, arrival of a new baby, or loss of a loved one or pet can cause insecurity, contributing to returning bedwetting. * Type 1 diabetes mellitus can first present as nocturnal enuresis.

is a leading cause for nocturnal enuresis among adults. Alcohol suppresses the production of anti diuretic hormones and irritates the detrusor muscle in the bladder. These factors, paired with the large amount of fluid ingested, particularly during binge drinking sessions or when paired with caffeinated drinks, can lead to episodes of nocturnal enuresis.

, and some not at all. The second ability that helps people stay dry is waking when the bladder is full. This ability develops in the same age range as the vasopressin hormone, but is separate from that hormone cycle. The typical development process begins with one- and two-year-old children developing larger bladders and beginning to sense bladder fullness. Two- and three-year-old children begin to stay dry during the day. Four- and five-year-olds develop an adult pattern of urinary control and begin to stay dry at night.


Diagnosis

Thorough history regarding frequency of bedwetting, any period of dryness in between, associated daytime symptoms, constipation, and encopresis should be sought.


Voiding diary

* People are asked to observe, record and measure when and how much their child voids and drinks, as well as associated symptoms. A voiding diary in the form of a frequency volume chart records voided volume along with the time of each micturition for at least 24 hours. The frequency volume chart is enough for patients with complaints of nocturia and frequency only. If other symptoms are also present then a detailed bladder diary must be maintained. In a bladder diary, times of micturition and voided volume, incontinence episodes, pad usage, and other information such as fluid intake, the degree of urgency, and the degree of incontinence are recorded.


Physical examination

* Each child should be examined physically at least once at the beginning of treatment. A full pediatric and neurological exam is recommended. Measurement of blood pressure is important to rule out any renal pathology. External genitalia and lumbosacral spine should be examined thoroughly. A spinal defect, such as a dimple, hair tuft, or skin discoloration, might be visible in approximately 50% of patients with an intraspinal lesion. Thorough neurologic examination of the lower extremities, including gait, muscle power, tone, sensation, reflexes, and plantar responses should be done during first visit.


Classification

Nocturnal urinary continence is dependent on three factors: 1) nocturnal urine production, 2) nocturnal bladder function and 3) sleep and arousal mechanisms. Any child will experience nocturnal enuresis if more urine is produced than can be contained in the bladder or if the detrusor is hyperactive, provided that he or she is not awakened by the imminent bladder contraction.


Primary nocturnal enuresis

Primary nocturnal enuresis is the most common form of bedwetting. Bedwetting becomes a disorder when it persists after the age at which bladder control usually occurs (4–7 years), and is either resulting in an average of at least two wet nights a week with no long periods of dryness or not able to sleep dry without being taken to the toilet by another person. New studies show that anti-psychotic drugs can have a side effect of causing enuresis. It has been shown that diet impacts enuresis in children.

). Some researchers, however, recommend a different starting age range. This guidance says that bedwetting can be considered a clinical problem if the child regularly wets the bed after turning 7 years old.


Secondary nocturnal enuresis

Secondary enuresis occurs ''after'' a patient goes through an extended period of dryness at night (six months or more) and then ''reverts'' to night-time wetting. Secondary enuresis can be caused by emotional stress or a medical condition, such as a bladder infection.


Psychological definition

Psychologists are usually allowed to diagnose and write a prescription for diapers if nocturnal enuresis causes the patient significant distress. Psychiatists may instead use a definition from the

Management

There are a number of management options for bedwetting. The following options apply when the bedwetting is not caused by a specifically identifiable medical condition such as a bladder abnormality or diabetes. Treatment is recommended when there is a specific medical condition such as

or relationships with family/friends. Only a small percentage of bedwetting is caused by a specific medical condition, so most treatment is prompted by concern for the child's ''emotional'' welfare. Behavioral treatment of bedwetting overall tends to show increased self-esteem for children. Parents become concerned much earlier than doctors. A study in 1980 asked parents and physicians the age that children should stay dry at night. The average parent response was 2.75 years old, while the average physician response was 5.13 years old. Punishment is not effective and can interfere with treatment.


Treatment approaches

Simple behavioral methods are recommended as initial treatment. Other treatment methods include the following: * Motivational therapy in nocturnal enuresis mainly involves parent and child education. Guilt should be allayed by providing facts. Fluids should be restricted 2 hours prior to bed. The child should be encouraged to empty the bladder completely prior to going to bed. Positive reinforcement can be initiated by setting up a diary or chart to monitor progress and establishing a system to reward the child for each night that they are dry. The child should participate in morning cleanup as a natural, nonpunitive consequence of wetting. This method is particularly helpful in younger children (<8 years) and will achieve dryness in 15-20% of the patients. * Waiting: Almost all children will outgrow bedwetting. For this reason, urologists and pediatricians frequently recommend delaying treatment until the child is at least six or seven years old. Physicians may begin treatment earlier if they perceive the condition is damaging the child's self-esteem and/or relationships with family/friends. * Bedwetting alarms: Physicians also frequently suggest bedwetting alarms which sound a loud tone when they sense moisture. This can help condition the child to wake at the sensation of a full
bladder The bladder () is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distens ...
. These alarms are considered more effective than no treatment and may have a lower risk of adverse events than some medical therapies but it is still uncertain if alarms are more effective than other treatments. There may be a 29% to 69% relapse rate, so the treatment may need to be repeated. * DDAVP (

, the hormone that reduces urine production during sleep. Desmopressin is usually used in the form of desmopressin acetate, DDAVP. Patients taking DDAVP are 4.5 times more likely to stay dry than those taking a placebo. The drug replaces the hormone for that night with no cumulative effect. US drug regulators have banned using desmopressin nasal sprays for treating bedwetting since the oral form is considered safer. * DDAVP is most efficient in children with nocturnal polyuria (nocturnal urine production greater than 130% of expected bladder capacity for age) and normal bladder reservoir function (maximum voided volume greater than 70% of expected bladder capacity for age). Other children who are likely candidates for desmopressin treatment are those in whom alarm therapy has failed or those considered unlikely to comply with alarm therapy. It can be very useful for summer camp and sleepovers to prevent enuresis. * Tricyclic antidepressants:

can reduce embarrassment for bedwetters and make cleanup easier for caregivers. These products are known as training pants or diapers when used for younger children, and as absorbent underwear or incontinence briefs when marketed for older children and adults. Some diapers are marketed especially for people with bedwetting. A major benefit is the reduced stress on both the bedwetter and caregivers. Wearing diapers can be especially beneficial for bedwetting children wishing to attend sleepovers or campouts, reducing emotional problems caused by social isolation and/or embarrassment in front of peers. According to a study of one adult with severe disabilities, extended diaper usage may interfere with learning to stay dry. * Waterproof mattress pads are used in some cases to ease clean-up of bedwetting incidents, however they only protect the mattress, and the sheets, bedding or sleeping partner may be soiled.


Unproven

* Acupuncture: While acupuncture is safe in most adolescents, studies done to assess its effectiveness for nocturnal enuresis are of low quality. * Dry bed training: Dry bed training is frequently waking the child at night. Studies show this training is ineffective by itself and does not increase the success rate when used in conjunction with a bedwetting alarm. * Star chart: A star chart allows a child and parents to track dry nights, as a record and/or as part of a reward program. This can be done either alone or with other treatments. There is no research to show effectiveness, either in reducing bedwetting or in helping self-esteem. Some psychologists, however, recommend star charts as a way to celebrate successes and help a child's self-esteem.


Epidemiology

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.
