Most children with testicular effusion belong to syringomyelia. If the effusion is not a lot and the tension is not very high when touched by hand, most of them can absorb and subside by themselves within one year of age, if the tension is high, surgery is required because syringomyelia can be divided into different types of non-transmissible and transmissible. Pay attention to observe whether there is a possibility of hernias and so on. A light transmission test with a flashlight is needed, and if the light transmission is good, the syringomyelia is a syringomyelia. If it is not translucent and can be returned by manipulation, aggravated when crying and can shrink when not crying, it may be a hernia, so it is best to take the baby to the hospital for a consultation to clarify the diagnosis.
