Inguinal hernia and hydrocele in children in Paris
Inguinal hernias and hydroceles are two very common conditions in pediatric urology. Although their clinical manifestations differ, they share a common anatomical cause: the persistence of the peritoneovaginal canal. Understanding this mechanism is essential for determining the indications for surgery, which aims to prevent complications that can sometimes be severe.
Anatomical origin: the peritoneovaginal canal
Urological Surgery in Paris & Neuilly
During fetal development, the testicle migrates from the abdominal cavity to the scrotum through a small canal called the peritoneovaginal canal. In most cases, this canal closes spontaneously before birth or during the first few weeks of life.
However, in some children, this canal remains partially or completely open, creating a connection between the abdomen and the external genitalia:
- If the canal is wide, abdominal organs (often a loop of intestine) can enter it: this is an inguinal hernia.
- If the canal is very narrow, only peritoneal fluid can flow into it: this is a communicating hydrocele.

Dr. Adam VardiAn inguinal hernia presents as a swelling (a “lump”) in the groin or scrotum. This swelling is often intermittent, appearing when the child screams, cries, or strains, and disappearing at rest.
The Risk of Hernia Strangulation
Unlike in adults, an inguinal hernia in children never heals on its own. The main risk is strangulation: a portion of the intestine becomes trapped in the canal, blocking blood flow (ischemia). This is an absolute surgical emergency characterized by a hernia that has become hard, very painful, and impossible to manually reduce. In infants, this can also compress the blood vessels of the testicle and compromise its viability.

Hydrocele: a condition that is often temporary
A hydrocele causes the scrotum to swell; it becomes taut but remains painless. It is caused by a buildup of fluid around the testicle.
Diagnosis and progression
Unlike a hernia, a hydrocele does not pose an emergency risk. In newborns, a hydrocele is frequently observed at birth and resolves on its own before the age of 18 months or 2 years as the canal closes. Therefore, simple monitoring is the standard approach during the first few years of life.
When should a hydrocele be treated surgically?
Surgery is recommended in two situations:
- If the hydrocele persists beyond the age of 2, indicating that the canal will not close on its own.
- If the swelling is very large or becomes bothersome for the child. The surgical technique is the same as that used for an inguinal hernia: it aims to close the opening to the abdomen to stop fluid from entering.
Special case: cord cyst
Sometimes, the peritoneovaginal canal closes at both ends but traps fluid in the middle. This forms a small, round, firm, and fixed mass located between the groin and the testicle. This is called a cord cyst. Treatment is similar to that for a hydrocele if the cyst does not resolve on its own or if it becomes large.
Postoperative Care and Recovery
Recovery following peritoneovaginal canal surgery is generally very straightforward:
- Anesthesia: The procedure is brief and performed on an outpatient basis.
- Pain: Pain is moderate and can be effectively managed with over-the-counter pain relievers (acetaminophen, ibuprofen).
- Return to normal activities: The child can resume normal activities quickly, although it is advisable to avoid rough play or sports for about ten days.
- Scarring: The scar is located in a natural crease of the groin and becomes virtually invisible over time.
In summary, while a hydrocele often allows for a wait-and-see approach, an inguinal hernia in a child requires rigorous surgical management to ensure the integrity of the abdominal and genital organs. Dr. Vardi tailors the treatment strategy based on the child’s age and the type of anatomical communication observed.
