The factors affecting the self-healing of ureteric reflux are not only age-related, but also the severity of the ureteric reflux. If the reflux is mild, there is a possibility that it can be self-healed, but when the reflux is severe, the probability of self-healing is usually very small. When ureteral reflux is mild and there is no ureteral dilatation, conservative treatment can be chosen, and there is a high probability of self-healing. Patients are advised to drink water and urinate regularly to prevent urinary tract infections, and antibiotics can be used to prevent urinary tract infections if necessary, such as quinolone antibiotics, which are recommended to be used in accordance with the doctor’s instructions. Quinolone antibiotics are not recommended for children. When ureteral reflux is severe, dilatation of the ureter may occur and kidney function may be affected. Surgical treatment, such as ureteral bladder reimplantation, is usually needed to restore the function of the ureter and the kidneys. When infants and children with ureteral reflux do not resolve spontaneously after a period of follow-up, or when new uncomfortable symptoms appear, it is recommended that they seek medical attention and treatment.
