A child with a traffic testicular syringomyelia was done this morning. After ligating the sphincter accurately and opening the sheath to release the fluid, I found that the testicle on the affected side was significantly smaller in size. I have encountered many cases like this, and I personally feel that the long-term immersion of a young child’s developing testicle in fluid will definitely have an adverse effect on its development. In particular, the testicular tissue is the most sensitive organ of the human body in terms of temperature requirements, and the temperature required by the testicles is 1-2 degrees Celsius below the normal human body temperature. It is known that in a cold environment, the skin of the scrotum will crumple and the testicular muscle will lift the testicles up to achieve the role of insulation; in a hot environment, the skin of the scrotum will unfold and the position of the testicles will fall to maintain the normal temperature of the testicles. It is because the development of the testes has its own strict requirements for temperature that its own highly regulated manner occurs. In children with syringomyelia, the testes are immersed in fluid for a long time, and the testes’ own temperature regulation mechanism is unable to function, inevitably resulting in impaired testicular development. Therefore, it is strongly recommended that parents of children with testicular syringomyelia must choose surgery for their children as soon as possible. Generally, after the age of 1 week, the sphincter cannot close by itself, so traffic testicular syringomyelia cannot heal by itself, and surgery can be chosen at this time. Surgery is the only curative treatment available, and it takes only a few minutes for a skilled specialist to complete.
