Enuresis, also known as bedwetting, is usually seen in children who involuntarily urinate after sleeping. Generally, by the age of 10, 5% of children have enuresis, and in a small number of cases, enuresis continues into adulthood. Enuresis is divided into primary enuresis and secondary enuresis. The causes of primary enuresis are directly related to delayed cortical development, deep sleep, psychological factors and genetic factors. The main treatment is to develop a good resting system and hygiene habits, avoid overwork, master the time and pattern of bedwetting, and wake up the child with an alarm clock at night to urinate 1 to 2 times. Sleep 1 to 2 hours during the day and avoid excessive excitement or strenuous exercise during the day to prevent sleeping too deeply at night. It can also be treated by interrupting urination exercises, urine holding exercises, and medication, depending on the patient’s own situation. Secondary enuresis is seen in patients with urinary tract obstruction, cystitis, neurogenic bladder and other diseases, and requires detailed examination to clarify the specific cause of enuresis for treatment. As mentioned above, enuresis in children is relatively common, and most of them can gradually improve with age and the gradual development of the patient’s cerebral cortex, so there is no need to worry too much. Only a few pathological causes need to be treated.
