Umbilical ureter cysts in children do not necessarily require surgery, and the specifics need to be determined according to the actual condition of the patient. Umbilical ureter cysts are usually caused by congenital factors that lead to the closure of the two ends of the umbilical ureter. If the cysts are small and benign, and there are no infections or other uncomfortable symptoms, they may not need to be treated with surgery, and can be observed on a regular basis. In children with umbilical ureter cysts, if the cysts are large and accompanied by infection, oozing fluid, pressure on the intestine and other uncomfortable symptoms, it is necessary to take surgical resection under the guidance of the doctor to strip the umbilical ureter. Therefore, when children develop umbilical ureter cysts, it is recommended to go to the hospital in time to complete the relevant examinations to assess the nature of the cysts, and treatment under the guidance of doctors.
