Hydrocele is a condition where fluid builds up in the thin sheath surrounding a testicle. This buildup causes swelling in the scrotum (the sac that holds the testicles). Although it often causes little or no pain, the swelling can be uncomfortable or worrisome, especially if it becomes very large
In this guide, we break down hydrocele into easy-to-understand sections—from its definition and how it forms, to its causes, symptoms, diagnosis, treatments, prevention methods, and common questions. Our goal is to provide an accessible resource that anyone can use to learn about this condition.
Hydrocele is defined as the abnormal collection of clear or straw-colored fluid in the tunica vaginalis, which is the pouch of tissue that covers the testicle. It is most common in newborns (where it is usually a congenital issue) and in adult men, where it can develop later in life.
Key points:
- Fluid accumulation: The fluid buildup causes a soft, smooth swelling on one or both sides of the scrotum.
- Mostly painless: Many men do not feel pain, although a heavy or dragging sensation may occur.
- Often harmless: In most cases, hydrocele is not dangerous and may even resolve on its own, especially in infants.
Pathophysiology of Hydrocele
Understanding the pathophysiology of hydrocele helps explain what is happening inside your body when this condition develops. Here, we look at the structure, blood supply, nerve supply, and functions related to the scrotum and testicle.
Structure
- Tunica Vaginalis: This is the double-layered membrane that surrounds each testicle. Under normal conditions, it contains a small amount of fluid that helps the testicle move smoothly.
- Testicle and Surrounding Tissue: The testicle sits inside the scrotum, supported by a network of connective tissues. When extra fluid accumulates in the tunica vaginalis, it creates a hydrocele.
Blood Supply
- Testicular Artery: Supplies oxygen-rich blood to the testicle.
- Pampiniform Plexus: A network of veins that drains blood away from the testicle. It also plays a role in regulating the temperature of the testicle, which is important for sperm production.
Nerve Supply
- Genitofemoral Nerve: Provides sensation to the upper scrotum.
- Ilioinguinal Nerve: Supplies the skin over the groin and part of the scrotum.
- These nerves help detect any changes, including pain or discomfort, in the scrotal region.
Functions
- Protection: The layers and fluid within the tunica vaginalis protect the testicle from friction and injury.
- Temperature Regulation: The blood vessels and surrounding tissue work together to maintain an optimal temperature for testicular function.
- Lubrication: The small amount of fluid normally present helps the testicle move within the scrotum without irritation.
When excess fluid accumulates, it can interfere with these functions and may be a sign of another underlying issue.
Types of Hydrocele
Hydroceles come in several forms. The main types include:
- Congenital Hydrocele:
- Occurs in newborns because the processus vaginalis (a passageway for testicular descent) fails to close completely.
- Acquired Hydrocele:
- Develops later in life, often due to injury, infection, or inflammation.
- Communicating Hydrocele:
- The fluid-filled sac is connected to the abdominal cavity. This type may change size throughout the day.
- Non-Communicating Hydrocele:
- The fluid is trapped in the scrotum with no connection to the abdomen.
- Secondary Hydrocele:
- Arises as a consequence of other conditions, such as infections, tumors, or inflammation.
Each type has its own causes, treatment options, and management strategies.
Causes of Hydrocele
Hydrocele can be triggered by several factors. Here are 20 possible causes:
- Congenital Defect:
- An incomplete closure of the processus vaginalis in infants.
- Idiopathic Development:
- No known cause; sometimes hydrocele forms without a clear reason.
- Infection:
- Inflammation due to infections like epididymitis or orchitis can lead to fluid buildup.
- Trauma:
- Injury to the scrotum can cause bleeding or fluid accumulation.
- Testicular Torsion:
- A twist of the spermatic cord may disrupt normal fluid balance.
- Inflammatory Conditions:
- Chronic inflammation in the scrotal area may cause fluid to collect.
- Tumors:
- Growths in the testicle or surrounding tissue can cause secondary hydrocele.
- Epididymal Cysts:
- Cysts in the epididymis may be associated with hydrocele formation.
- Inguinal Hernia:
- A hernia in the groin can disrupt the normal anatomy, leading to fluid collection.
- Post-Surgical Complications:
- Surgeries in the groin or scrotal area may lead to a hydrocele.
- Parasitic Infection:
- In some regions, filarial infection (caused by parasites) can lead to hydrocele.
- Obstruction of Lymphatic Drainage:
- Blockage in the lymphatic system may result in fluid accumulation.
- Vasectomy:
- In rare cases, complications after vasectomy may cause fluid buildup.
- Autoimmune Reactions:
- The body’s immune response can sometimes lead to inflammation and fluid retention.
- Radiation Therapy:
- Exposure to radiation in the pelvic area can alter tissue function.
- Systemic Diseases:
- Certain conditions that cause fluid retention (such as heart or liver disease) might contribute.
- Recurrent Infections:
- Multiple episodes of infection in the scrotum may gradually lead to hydrocele.
- Chronic Epididymitis:
- Long-term inflammation of the epididymis can be a contributing factor.
- Exposure to Toxins:
- Rare exposure to toxins or chemicals may result in tissue inflammation.
- Genetic Predisposition:
- A family history of hydrocele or related conditions can sometimes play a role.
