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 at age 15. Enuresis affects the physical and mental health of children, leading to reluctance to participate in group activities, reduced academic performance and many problems in life, and should be treated actively. Common causes of enuresis are: 1, decreased secretion of antidiuretic hormone, increased nocturnal urine output; 2, urodynamic examination found that there is a forced urethral muscle instability, bladder with or without inhibitory contraction, forced sphincter contraction is not coordinated, the functional capacity of the bladder is reduced; 3, the cerebral cortex is not easy to be excited, nocturnal arousal disorders to the extent that the child can not be detected when the bladder is full. Ask the history, most of the children with enuresis are difficult to wake up at night, and many of them still have urinary urgency during the day, and some of the symptoms disappear as they grow older; The treatment of enuresis is still a difficult problem, but it is not hopeless, and it requires the cooperation and long-term persistence of the parents. Generally need to use a variety of methods of joint treatment: 1, less water before bedtime; 2, night parents should regularly wake up to urinate, or the application of wake-up alarm clock; 3, can not be overworked; 4, the application of drugs to reduce the amount of nighttime urination; 5, oral medication to increase the excitability of the cerebral cortex, so that the child’s bladder is full easily awakened; 6, the application of medication to reduce the incoherent contraction of the bladder; 7, biofeedback and electrical stimulation therapy to reduce the uninhibited contraction of the bladder, to reduce the bladder. Reduce uninhibited bladder contractions and increase bladder capacity.
