How should hydrocele be treated?

Patient's question:

Male
Detailed medical condition and purpose of consultation: My son is over four years old. Around the time he was two, we noticed that the left testicle was slightly larger (this was not the case before the age of two). However, when we asked him if it hurt, he said it didn't, and it did not affect his eating, sleeping, playing, or walking. At first, we thought it was a hernia, but after going to the hospital for a check-up, the doctor said it was hydrocele in children, which did not require treatment and would gradually improve with age. Indeed, it disappeared on its own after some time. But later, for some reason, it occasionally reappeared, especially when the child cried. It would then improve after a while, and the duration of the issue varied. In October, there was one instance where he cried very intensely

Doctor's answer:

Hello, hydrocele in infants and young children can often be absorbed on their own during development. Therefore, unless the hydrocele is very large, treatment is generally not required. Surgical treatment is suitable for larger hydroceles. Testicular hydroceles usually require a tunica vaginalis (tunica vaginalis inversion), spermatic cord hydroceles require cyst excision, and communicating hydroceles are treated with high ligation of the processus vaginalis combined with tunica vaginalis inversion. Small hydroceles can be treated with cyst puncture and drainage with medication.
It generally does not affect the child's future fertility or other sexual functions. We recommend that you take your child to the hospital for treatment as soon as possible. Wishing your child a speedy recovery!
