If the bedwetting is only occasional, there is no need to deal with it. If there are at least 2 times of involuntary urination at night within 1 week and it lasts for more than 3 months, it is necessary to go to the hospital for consultation and treatment, and a sacrococcygeal plain film can be performed to exclude the possibility of invisible sacral fissure. Treatment can be done through the following: 1. behavioral treatment, which can control the child’s pre-sleep drinking and reduce the child’s pre-sleep drinking, thus reducing the number of nighttime urination and the volume of urination; 2. alarm devices can be used to remind the child to urinate at night during sleep; 3. oral medication can be used, such as Miren, Shrinking Spring Pills, Shrinking Spring Capsules, etc.; 4. acupuncture or tui-na, physiotherapy, etc. can be used for treatment; 5. The treatment can be carried out by biofeedback and magnetic stimulation.
