In infants with scrotal effusion, if the effusion is caused by infection, anti-infective treatment is needed; if it is not caused by infection, testicular syringomyelia is considered. Syringomyelia is a condition in which the peritoneum is brought down during the descent of the testicle to form a sheath. Most children can slowly close the sheath on their own after birth. The possibility of the sphincter closing in children with effusion is relatively small, and the fluid in the abdominal cavity will fall down the sphincter into the scrotum, forming a scrotal mass that will be shiny and can be observed until the age of two, and ultrasound will be done after the age of two. If the amount of fluid is high, active surgery is recommended. If the amount of fluid accumulation is low, surgery can be observed until the age of three to four years. This surgery is the most common procedure in pediatric surgery and is usually fine.
