Hydrocele in children

What is hydrocele in children?

A hydrocele in children is a collection of fluid between the membranes surrounding the testicle, resulting in swelling in the scrotum. The condition is common in infants and is often caused by a congenital opening between the abdomen and the scrotum that does not close properly. This opening allows fluid to pass into the scrotum, causing the swelling.

Signs and symptoms of a hydrocele include swelling, which can vary in size throughout the day and often becomes more noticeable when the child is crying or active. The condition is usually painless and rarely requires emergency treatment. In most cases, a hydrocele resolves spontaneously within the first year of life.

Types of hydrocele in children

There are two main types of hydrocele in children:

• Communicating hydrocele: This type occurs when there is an open connection between the abdomen and the scrotum. The fluid can move back and forth, meaning the swelling can change size throughout the day. This type of hydrocele is more likely to require surgical treatment because the connection does not always close on its own.

• Non-communicating hydrocele: In this type, the fluid is trapped in the scrotum without an open connection to the abdomen. This type is highly likely to disappear spontaneously as the fluid is gradually reabsorbed by the body.



Distinguishing between these two types is important, as it directly affects the treatment plan and the likelihood of a spontaneous recovery.

Is hydrocele dangerous?



Hydrocele in children is usually harmless and rarely causes pain. In infants, the condition often disappears on its own. The child should be examined if the swelling increases, causes discomfort, does not disappear with age, or if an inguinal hernia is suspected.

Can hydrocele go away on its own?

Yes. In young children, hydrocele often resolves spontaneously, especially during the first year of life. If the swelling persists, gets larger, or varies significantly in size, the child may need evaluation for treatment.

What is the difference between a hydrocele and an inguinal hernia?

In hydrocele, there is fluid around the testicle or in the scrotum. In inguinal hernia, abdominal contents, such as intestines, can pass through an opening from the abdominal cavity. Inguinal hernias more often require surgical treatment because in rare cases, entrapment can occur.

Does hydrocele affect fertility?

A common hydrocele in children usually does not affect fertility. Most children develop normally. If the swelling is large, persistent, or atypical, the child should be evaluated to ensure that there is no other condition.

When does hydrocele require treatment?

In many cases, hydrocele in children will go away on its own within the first year of life. However, treatment may be necessary if:

• The swelling does not subside after the first year of life.
• The swelling gets bigger over time.
• There is suspicion of concurrent inguinal hernia, which may require surgical intervention.

Doctors typically assess the need for treatment based on the child's age, the severity of symptoms, and the risk of complications. If treatment is necessary, it is usually performed surgically to close the connection to the abdominal cavity and remove the fluid.

How is hydrocele diagnosed?

The diagnosis of a hydrocele is usually made through a clinical examination. The doctor evaluates the size of the swelling, its consistency, and whether it changes throughout the day. To confirm the diagnosis, the doctor may perform a transillumination test, where a light source is held against the scrotum to see if the fluid-filled sac lights up.

If there is any doubt about the diagnosis, or if other conditions such as an inguinal hernia are suspected, an ultrasound can provide a detailed view of the area. This method is completely painless and provides precise information about the location of the fluid and any other potential abnormalities.

What does the treatment of hydrocele involve?

If treatment for a hydrocele is necessary, it is typically performed surgically. The operation, called a hydrocelectomy, involves closing the connection to the abdomen and removing the accumulated fluid. The procedure is performed as day surgery, meaning the child can go home the same day.

After surgery, there may be some slight swelling and discomfort for a short time, but most children quickly return to their normal activities. Complications are rare, and the surgery has a high success rate. Parents should carefully follow the doctor's post-operative instructions to ensure a quick and smooth recovery.
