The American Psychological Association defines enuresis as bedwetting between the ages of 5 and 7. 15-20% of 5-year-olds still wet the bed, with the number decreasing by 15% each year thereafter, and about 1% of children still wet the bed by the age of 15. Enuresis affects children’s physical and mental health, leading to unwillingness to participate in group activities, reduced academic performance, and brings a lot of trouble in life, and should be treated actively. Common causes of enuresis include: 1. Decreased secretion of antidiuretic hormone and increased nocturnal urine output. 2, urodynamic examination found that there is instability of the urethral muscle, bladder with or without inhibitory contraction, uncoordinated contraction of the urethral sphincter, and reduction of the functional capacity of the bladder. 3.The cerebral cortex is not easily excited, and nocturnal awakening is impaired, so that the child cannot notice when the bladder is full. Ask the medical history, most children with enuresis are difficult to wake up at night, and many have urinary urgency during the day, and some of the symptoms disappear with age. The treatment of enuresis is still a difficult problem, but it is not hopeless and requires the cooperation of parents and long-term persistence. Generally need to use a variety of methods of joint treatment: l, less water before bedtime; 2, night parents should regularly wake up to urinate, or the application of wake-up alarm clock. 3, not excessive fatigue; 4, should not be overly tired; 4, the daytime urinary urgency phenomenon. 3, not excessive fatigue; 4, the application of drugs to reduce the amount of urine at night; 5, oral medication to increase the excitability of the cerebral cortex, so that the child is easy to wake up when the bladder is full. 6, Application of drugs to reduce the uncoordinated contraction of the bladder. 7, Biofeedback and electrical stimulation therapy to reduce uninhibited bladder contractions and increase bladder capacity.
