In ICD-10, encopresis and enuresis are included in the section of "F98 other behavioural and emotional disorders with onset usually occurring in childhood and adolescence" as nonorganic enuresis (F98.0) and nonorganic encopresis (F98.1). Nonorganic enuresis is defined as "a disorder characterized by involuntary voiding of urine, by day and/or by night, which is abnormal in relation to the individual's mental age" (ICD-10, WHO 1992, p285) and is not caused by organic reasons such as neurological disorder.
 Nonorganic encopresis is defined as "repeated voluntary or involuntary passage of faeces in places not appropriate for that purpose in the individual's own sociocultural setting" (ICD-10,1992, P286).
 In ICD-11, these are grouped as Elimination Disorders, and termed Enuresis (6C00) and Encopresis (6C01), respectively. The features of these disorders are "repeated and persistent voiding of urine into bed or clothes" (Enuresis, ICD-11) and" repeated and persistent passage of faeces in inappropriate places" (Encopresis, ICD-11). To make a diagnosis, the inappropriate voiding of urine or passage of faeces should continue after the individual has reached a developmental age when urinary or faecal continence is expected. Elimination Disorders include both voluntary and involuntary cases. In ICD-11, the wording of "nonorganic" disappeared from the name of the disorder, but its description remains nonorganic. One of the major changes to the concept is that both Encopresis and Enuresis can be diagnosed in adults, which is different from ICD-10. In addition, their descriptions are more detailed in ICD-11 and are divided into several types that are clinically appropriate. The descriptions of "boundary with normality" "developmental presentations", "gender- and/or sex-related features", and "differential diagnosis" make it clearer and easier to use in a clinical setting. In this article, I will discuss Enuresis and Encopresis in ICD-11 in more detail.
