Testicular effusion does not have to be treated surgically. Testicular effusion is also known as testicular syringomyelia, where the testicular sphincter closes normally, but there is more fluid in the testicular sphincter sac. If the amount of fluid accumulation is small, there is usually no need for any treatment. If the amount of fluid accumulation increases, resulting in a feeling of falling, swelling and pulling in the scrotum, and a huge testicular sphincter accumulation can cause the penis to retract into the foreskin and affect urination, this condition can be treated surgically. In general, if the testicular sphincter is larger than 4cm, surgery can be performed. The surgery is to drain the testicular sphincter and then turn the testicular sphincter over, and then the surgery is over, which is a routine surgery.
