First, general treatment Do not blame and scold the child, but give encouragement so that the child will have the determination to cure the enuresis. Parents should give high care and love to the children. Forbid drinking water after dinner, put the child to urinate before bedtime, and wake the child up to urinate once or twice at night. II. Drugs ① Promethazine: It is a central stimulant, which can reduce the depth of sleep. 25～50mg should be taken orally every night for 3～4 months. If relapse after stopping the drug, it can be given again. ② Parasympathetic blocker: Probenecid or oxybutynin (Oxybutynin, i.e., ditropan, uridorin). It is taken orally before going to sleep to relax the detrusor muscle and inhibit bladder contraction. ③Ephedrine 25mg orally before bedtime. It can increase the contraction of the bladder neck and posterior urethra. Bladder training Ask the child to extend the interval of urination as much as possible during the day, gradually from once every 1/2 to 1 hour to once every 3 to 4 hours, in order to expand the bladder capacity. Conditioned reflex training Use an alarm device to train the child to wake up before he/she loses urine. Once the electronic pad is wet, the electric bell will be connected to the circuit to wake the child up to urinate; if the effect is not good, promethazine can be added to reduce the depth of sleep. Generally, 70-80% of primary enuresis can be cured after 1 to 2 months of training.
