Urinary incontinence (bedwetting, enuresis) is the commoswarm urinary symptom in children and teenagers and have the right to cause major distress and anxiety for the affected kids and their paleas. Physiological and also non-physiological kinds of urinary incontinence are sometimes difficult to tell acomponent in this age team.

This write-up is based on schosen literary works retrieved by a PubMed search and also on an interdisciplinary experienced consensus.

Results and also conclusion

Nocturnal enuresis has a variety of causes. The major causative factors in monosymptomatic enuresis nocturna (MEN) are an impaired capability to wake up when the bladder is full, as a result of impaired or absent perception of fullness in the time of sleep, and an imbalance in between bladder capacity and also nocturnal urine manufacturing. On the various other hand also, non-monosymptomatic enuresis nocturna (non-MEN) is commonly traceable to bladder dysattribute, which is additionally the primary cause of diurnal incontinence. A fundamental battery of non-invasive diagnostic tests usually suffices to identify which type of incontinence is existing. Additional and also even more particular experimentation is indicated if an organic reason is suspected or if the treatment stops working. The mainstay of therapy is urotherapy (all non-surgical and also non-pharmacological therapeutic modalities). Some patients, however, will require supportive medication in addition. Urinary incontinence has actually different causes in kids and adults and also need to therefore be diagnosed and also treated differently as well. All doctors that treat the affected youngsters (not just pediatricians and household medical professionals, however likewise pediatric nephrologists, urologists, pediatric surgeons, and also kid psychiatrists) have to be aware of the certain features of urinary incontinence in childhood.

Urinary incontinence (bedwetting, enuresis) is a multidisciplinary and also interdisciplinary problem that often presents a permanent source of dianxiety for the impacted children and also their parents.


This evaluation write-up is the outcome of interdisciplinary collaboration in between urologists, pediatricians, and child and adolescent psychiatrists. It is based upon selective literary works retrieved from PubMed, consensus files of the International Children´s Continence Society (ICCS) (1– 4), the reminder of the European Association of Urology (e1), the S1 guideline of the Gerguy Society of Child and Adolescent Psychiatry (5), and also the hands-on of the consensus team for continence training in youngsters and teens (KgKS) (6).

On the basis of meanings of various forms of enuresis we present guidelines for a stepwise diagnostic approach and define indication-certain, evidence-based therapeutic interventions.


The symptom of involuntary urine loss is termed urinary incontinence (enuresis, bedwetting). For nocturnal urinary incontinence, the terms enuresis and enuresis nocturna are provided synonymously (Figure). Up to the 5th year of life, urinary incontinence is pertained to as physiological.

Diagnostic categories in urinary incontinence

The basis of successful therapy is the distinction between bedwetting just at night (monosymptomatic enuresis nocturna, MEN) and nocturnal bedwetting through additional diurnal symptoms (non-monosymptomatic enuresis nocturna, non-MEN) and also isolated day-time incontinence (mostly combined with various other symptoms of bladder dysfunction) (Box 1).

Day-time incontinence


Imperative urge to urinate

Holding maneuvers

Infrequent voiding

Staccato micturition


In Germany type of, the ICCS interpretations of 2006 pertaining to urinary incontinence in children (1) have end up being established (Figure, eFigure 2). Non-MEN and isolated enuresis during the day are still often combined under the term pediatric urinary incontinence. Primary enuresis is the term offered for nocturnal enuresis persisting considering that birth; secondary enuresis describes enuresis that creates de novo after a dry phase of at least six months.

The causes of urinary incontinence are greatly functional impairments; seldom, they are underlying anatomical or neurological conditions.


Children construct stable bladder control in the 3rd to 6th year of life—initially during the day and also later additionally throughout the night (e2). At age 7, 10% still have nocturnal enuresis, 2% to 9% are impacted throughout the day (7, e3). The spontaneous remission rate is about 15% per year (8, e4). Only a third of those affected seek out healthcare services, which provides a clear indication of how the symptoms are rated exceptionally in different ways in different families (e5).

Etiology and pathophysiology

Urinary incontinence is a heterogeneous entity that has actually multifactorial causes and is affected by comorbidities (Figure, eBox).

Delayed maturation at various levels of bladder control

Familial trait/genetic disposition

Difficult to rouse from sleep

Small bladder capacity

Circadian ADH secretion is impaired

Drinking habits that may contribute to the problem

Psychological triggers (only in additional MEN)

Sleep disorders

Physiological urinary incontinence

This term clarifies urinary incontinence as a symptom that is related to as normal in the first few years of life and classed as pathological just after the 5th year of life has actually been completed (e2). The selection of normal continence development is, however, exceptionally wide, so that we deserve to assume that many children suffer “physiological” urinary incontinence past the completed fifth year of life (“late developers”). The clinical and apparative findings in such kids are normal.

Pathological urinary incontinence

Organic and also functional (or psychosomatic) forms of urinary incontinence need to be distinguished (Figure).

Functional urinary incontinence

This has all develops of enuresis without any kind of structural anatomical or neurological deficit (1). Another term that is applied to this team is “functional urinary incontinence,” however this has not been uniformly defined (Figure, eBox).

Organic urinary incontinence

This develop of incontinence is rare. Especially in treatment-refractory cases, one-of-a-kind initiatives need to go right into the detection of possible organic reasons. The long-term leaking of tiny quantities of urine during the day and also at night is typical for girls via duplex kidney and ectopic ureter (an abgenerally located terminal percentage of the ureter). Malformations of the urethra might additionally be the reason of organic urinary incontinence (Figure).

Polyuric renal disease—such as tubulopathies, chronic renal faientice, or diabetes insipidus—can likewise manifest as enuresis. Normally, children awake at night owing to a pronounced sensation of thirst.

Neurogenic disorders: In congenital (for instance, myelomeningocele/spina bifida) or obtained neoplastic or inflammatory disorders of the nervous mechanism, the innervation of the bladder is often influenced. Occult spinal dysraphisms (for instance, spina bifida occulta, tethered cord syndrome, sacral agenesis) often remajor undetected for a lengthy time. The clinical attributes of a neurogenic bladder depend on the place of the lesion and is heterogeneous (for instance, pathological residual urine, represent urinary tract infections, urinary incontinence, doing not have perception of the have to urinate, abnormal uroflowmeattempt, thickened and also trabeculated bladder wall). In the rare “non-neurogenic neurogenic bladder,” (Hinmale syndrome), the symptoms resemble those of neurogenic bladder, however no neurological lesion is established.

Monosymptomatic enuresis (MEN)

The reasons of MEN are not fully defined. It may be assumed that a mix of developmental delays in neurological bladder control and the regulation of urine production play the crucial part (2) (eBox).

Non-monosymptomatic enuresis nocturna and also bladder dysattribute with isolated day-time incontinence

These forms are subcategorized into clinical subgroups according to their day-time symptoms: overactive bladder, discoordinated micturition, and also infrequent voiding (Figure).

Overenergetic bladder

The primary pathophysiological principle is that a child’s command over his/her bladder manage has actually not completely matured so that physiological urinary incontinence of early on childhood persists. The European Bladder Dysfunction Study (EBDS) did not discover any correlation in between clinical urge symptoms and also cystomanometric detrusor overactivity (9). It is likely that the overactive bladder in children is pathophysiologically not similar to the overenergetic bladder in adults. The cardinal symptom of overenergetic bladder is an imperative urinary urge. By purposely restricting liquid intake and paying regular visits to the toilet many type of kids remajor continent throughout the day, but once these control mechanisms are absent—for instance, throughout sleep—such kids begin wetting themselves.

Discoordinated micturition

Discoordinated micturition is characterized by ongoing tightening of the pelvic floor throughout micturition and resulting bladder voiding problems (9). Mostly, this is because of gained malattribute (for instance, an incorrect sitting posture, or as a reaction to painful micturition during urinary tract infections/Lichen sclerosus). The cardinal symptoms are a weak urine stream and staccato micturition. Urinary tract infections and also bowel voiding disorders are prevalent comorbidities.

Inconstant voiding

Wetting have the right to additionally be the consequence of habitual delays to micturition, with holding maneuvers being the cardinal clinical symptom (e3). Since healthy and balanced kids might likewise delay voiding, the degree at which this behavior becomes pathological is not clearly identified. In excessive situations, the result might be an underenergetic bladder (in the past referred to as “lazy bladder syndrome,” hypotonic or atonic bladder). In this scenario, the perception of a complete bladder disshows up first and then, as an outcome of long-term overextending, the bladder muscles shed their power to contract. The diagnostic categorization into among the over stated 3 subteams (Figure) is frequently not clear-cut; overlaps in between the different entities exist, the cardinal symptoms are subjective, and they may readjust over time. The recommendation is to record the objectifiable parameters descriptively on the basis of protocols (eFigure 1a and ​1b)1b) (Box 4) (1).
