Abstract
Nocturnal enuresis (NE) can be defined as an involuntary passage of urine during sleep beyond the age of 5 years. It can be further divided into primary which is bedwetting in a child who had never been dry, and secondary when it occurs after a continuous dry period more than 6 months. The etiology of enuresis is not completely understood.
Infact, several factors have been associated with an increased risk of bed-wetting, including: younger age, male sex, black race, history of urinary tract infection, obesity and a family history of enuresis are also likely risk factors. Various multiple conditions may cause enuresis, either causative or comorbid. They can influence management and prognosis. Other conditions may also include chronic kidney disease, neurogenic bladder, anorexia or other behavioral disorders, sickle cell disease, and hyperthyroidism.
Nocturnal enuresis may cause secondary emotional and social problems in children who continue to wet their beds. Although enuretic children seem to have many accompanying psychological problems, it must be investigated whether these problems are the results or etiological factors of enuresis. The recommendation for treatment requires a thorough analysis of the relative importance of the different pathogenetic factors and their causes in the individual child with nocturnal enuresis.
Aim of the Work:
This study aimed to determine the prevalence of nocturnal enuresis and identify the common risk factors associated.
