==Overview==
==Overview==
[[Urinary incontinence]] in [[children]] is a very familiar finding and complaint amongst [[patients]] and their caregivers. The earliest documentation of [[urinary incontinence]] dates back to 1550 BC in the [[Ebers papyrus]]. It is broadly classified into [[physiological]] and [[pathological]] with its various subdivisions, and [[nocturnal enuresis]] can be categorized into primary and [[secondary]]. The [[pathophysiology]] of [[urinary incontinence]] in [[children]], particularly [[enuresis]], can be described as increased [[urine]] production at night, reduced [[Urinary bladder|bladder]] capacity at night, and awakening [[disorder]]. The [[causes]] of [[urinary incontinence]] in [[children]] are identified based on the sub-classification of [[pathological]] [[Urinary incontinence|incontinence]]. Differentials include [[diabetes mellitus]], [[diabetes insipidus]], and [[Urinary tract infections|urinary tract infection]]. [[Children]] achieve the ability to [[control]] their [[Urinary bladder|bladder]] between the ages of 3 and 6 [[Year|years]]. This begins initially during the daytime and nighttime control is achieved much later. [[Nocturnal enuresis]] is seen more frequently in boys. There is no documented [[racial]] predisposition for [[enuresis]]. Some [[risk factors]] include, [[age]] less than 5 [[Year|years]], positive [[family history]], [[family]] size, and [[birth]] order. Certain [[complications]] are poor [[self-esteem]] and inability to socialize with [[Peer support|peers]]. [[Prognosis]] is generally good due to the high chances of spontaneous [[resolution]] at the [[rate]] of 15% per [[year]]. The focus is to eliminate any [[potential]] organic [[Causes|cause]] of [[Urinary incontinence|incontinence]] and to classify and identify the type of functional [[Urinary incontinence|incontinence]] using detailed [[History and Physical examination|history]] and [[Non-invasive (medical)|non-invasive]] [[Procedure|procedures]]. Identify any [[comorbidities]] which are mostly [[psychological]] occurring alongside [[Urinary incontinence|incontinence]]. Fundamental [[diagnosis]] includes taking a detailed [[History and Physical examination|history]] using a standardized [[questionnaire]]. The primary aim of a [[physical examination]] is to look for possible organic [[causes]] of [[Urinary incontinence|incontinence]] and [[comorbidities]]. [[Urinalysis]] is essential to rule out [[urinary tract infections]]. [[Ultrasonography]] is a useful tool when further [[diagnostics]] is required especially in situations of a likely organic [[Causes|cause]] or a [[lack of response]] to [[therapy]]. Uroflowmetry and [[Urodynamics|urodynamic]] studies are additional [[diagnostic]] studies that can be employed. Urotherapy encompasses all non-[[pharmacological]] and non-[[surgical]] [[treatment]] methods employed in the [[treatment]] of [[urinary incontinence]] in [[children]]. [[Desmopressin]] and [[oxybutynin]] are common [[drugs]] used for the [[pharmacological]] management of [[urinary incontinence]] in [[children]]. [[Surgery]] is not routinely employed as a form of [[treatment]] but it might be of importance in correcting some organic [[causes]] of [[urinary incontinence]] in [[children]]. There are no documented primary [[Preventive care|preventive]] measures available for [[urinary incontinence]] in [[children]].

Overview

Urinary incontinence in children is a very familiar finding and complaint amongst patients and their caregivers. The earliest documentation of urinary incontinence dates back to 1550 BC in the Ebers papyrus. It is broadly classified into physiological and pathological with its various subdivisions, and nocturnal enuresis can be categorized into primary and secondary. The pathophysiology of urinary incontinence in children, particularly enuresis, can be described as increased urine production at night, reduced bladder capacity at night, and awakening disorder. The causes of urinary incontinence in children are identified based on the sub-classification of pathological incontinence. Differentials include diabetes mellitus, diabetes insipidus, and urinary tract infection. Children achieve the ability to control their bladder between the ages of 3 and 6 years. This begins initially during the daytime and nighttime control is achieved much later. Nocturnal enuresis is seen more frequently in boys. There is no documented racial predisposition for enuresis. Some risk factors include, age less than 5 years, positive family history, family size, and birth order. Certain complications are poor self-esteem and inability to socialize with peers. Prognosis is generally good due to the high chances of spontaneous resolution at the rate of 15% per year. The focus is to eliminate any potential organic cause of incontinence and to classify and identify the type of functional incontinence using detailed history and non-invasive procedures. Identify any comorbidities which are mostly psychological occurring alongside incontinence. Fundamental diagnosis includes taking a detailed history using a standardized questionnaire. The primary aim of a physical examination is to look for possible organic causes of incontinence and comorbidities. Urinalysis is essential to rule out urinary tract infections. Ultrasonography is a useful tool when further diagnostics is required especially in situations of a likely organic cause or a lack of response to therapy. Uroflowmetry and urodynamic studies are additional diagnostic studies that can be employed. Urotherapy encompasses all non-pharmacological and non-surgical treatment methods employed in the treatment of urinary incontinence in children. Desmopressin and oxybutynin are common drugs used for the pharmacological management of urinary incontinence in children. Surgery is not routinely employed as a form of treatment but it might be of importance in correcting some organic causes of urinary incontinence in children. There are no documented primary preventive measures available for urinary incontinence in children.
