Testicular effusion should refer to testicular sphincter effusion, which is a common and frequent disease with clinical manifestations of swelling and discomfort in the affected scrotum, and severe testicular sphincter effusion can affect urination. The testes are located in the retroperitoneum at the beginning during embryonic development, gradually descending and descending into the scrotum at birth, so the testes are connected to the abdominal cavity at the beginning and the cavity is closed after birth. Normally there is a little fluid in the testicular sphincter cavity, which plays the role of lubrication. If the testicular sphincter cavity is still connected to the abdominal cavity after birth, testicular sphincter effusion will form. In addition, inflammation, infection, trauma and other factors can also cause testicular syringomyelia. Treatment should still be surgical. When testicular sphincter effusion appears, you should still visit the urology department of the hospital for further treatment under the guidance of a doctor.
