Hydrocele is a relatively common medical condition that affects males, especially newborns and older men. It occurs when fluid accumulates in the scrotum around the testicle, leading to swelling. Though typically painless, a hydrocele may signal an underlying issue that warrants medical attention. With awareness, early detection, and effective management, hydroceles can be resolved without complications.
This comprehensive guide explores what hydroceles are, their types, symptoms, causes, diagnosis, and available treatments—based on reliable medical insights and diagnostic expertise from centers like Sparsh Diagnostic Centre.
What Is a Hydrocele?
A hydrocele is a fluid-filled sac surrounding a testicle that causes swelling in the scrotum. It is usually not painful and is often benign. Hydroceles are more common in infants but can also develop in adult men due to injury, inflammation, or underlying conditions.
Types of Hydrocele
Hydroceles are categorized into two main types:
1. Primary Hydrocele
This type is not associated with any underlying disease or condition. It may develop gradually and is often idiopathic, meaning the exact cause is unknown. Primary hydroceles are non-communicating, where the fluid is trapped and does not flow back into the abdomen.
Types of Primary Hydrocele
Primary hydroceles can be further classified into four subtypes:
Congenital Hydrocele
Occurs in newborns when the processus vaginalis (a thin membrane extending from the abdomen into the scrotum) fails to close. This allows fluid to flow into the scrotal sac.Infantile Hydrocele
Found in infants and young children; the processus vaginalis remains open up to the level of the internal inguinal ring but doesn’t communicate with the peritoneal cavity.Encysted Hydrocele
A closed sac of fluid within the spermatic cord with no connection to the peritoneal cavity or scrotal sac.Vaginal Hydrocele (Primary Vaginal Hydrocele)
This is the most common type in adults and involves the tunica vaginalis (a covering of the testis) getting filled with fluid.
2. Secondary Hydrocele
This occurs due to an underlying issue such as:
Testicular infection (epididymitis or orchitis)
Trauma or injury to the scrotum
Testicular tumors
Post-surgical complications
Unlike primary hydroceles, secondary hydroceles require treatment of the underlying cause first.

What Causes a Hydrocele?
In Infants:
Hydroceles in babies are usually congenital, caused by the incomplete closure of the processus vaginalis during fetal development. This allows peritoneal fluid to accumulate in the scrotum.
In Adults:
Hydroceles in adult men may be due to:
Inflammation or Infection: Epididymitis or orchitis.
Injury or Trauma: To the scrotal area.
Testicular Tumors: Can lead to fluid buildup.
Radiation or Surgery: After treatment for varicoceles or hernias.
Signs and Symptoms of Hydrocele
Many hydroceles are asymptomatic. However, when symptoms do occur, they may include:
Scrotal Swelling: Often painless, noticeable increase in scrotum size.
Heaviness in the Scrotum
Discomfort with Movement
Pain (in case of infection or trauma)
Visible Fluid Buildup: Especially under a light source (transillumination).
In babies, parents may notice a swelling that fluctuates in size, often becoming larger when the baby is crying or straining.
Hydrocele vs. Other Conditions
Hydroceles can mimic other scrotal swellings. It’s important to differentiate hydroceles from:
Inguinal Hernia
Varicocele
Testicular Tumor
Spermatocele
Epididymal Cyst
A medical evaluation is crucial for an accurate diagnosis.
How Is a Hydrocele Diagnosed?
At advanced diagnostic centers like Sparsh Diagnostic Centre, the following diagnostic methods are used:
1. Physical Examination
The doctor palpates the scrotum for swelling or tenderness. Hydroceles typically feel smooth and are located in front of the testicle.
2. Transillumination
A light is shined through the scrotum. A hydrocele will allow light to pass through the fluid, distinguishing it from solid masses.
3. Ultrasound
A scrotal ultrasound provides a clear image and helps differentiate hydrocele from tumors, hernias, or infections.
4. Urine and Blood Tests
To rule out infections or inflammation that may be causing the hydrocele.
Complications of Hydrocele
Though hydroceles are often benign, if left untreated, complications can occur:
Infection of the fluid (pyocele)
Pressure on testicular structures
Infertility (if related to underlying causes)
Misdiagnosis of underlying malignancy
Prompt evaluation is important to avoid complications.
Treatment Options for Hydrocele
1. Observation
For infants and small, asymptomatic hydroceles, no treatment is needed as they often resolve by the age of 1-2 years.
2. Surgical Intervention
When hydroceles persist or cause discomfort, surgery is recommended:
Hydrocelectomy
Most common surgical procedure.
Involves removal or drainage of the fluid-filled sac.
Can be done under general or local anesthesia.
Usually a daycare or short-stay procedure.
3. Aspiration and Sclerotherapy
Involves draining the fluid and injecting a sclerosing agent to prevent recurrence.
Typically reserved for patients who cannot undergo surgery.
Higher recurrence rate compared to hydrocelectomy.
Recovery After Hydrocelectomy
Hospital Stay: Often same-day discharge.
Downtime: 1-2 weeks of limited activity.
Discomfort: Mild swelling and bruising are common.
Care Tips:
Wear scrotal support
Apply cold packs
Avoid strenuous activities
Keep the surgical site clean
Can Hydrocele Be Prevented?
While congenital hydroceles cannot be prevented, adult-onset hydroceles can sometimes be avoided by:
Preventing scrotal injuries
Prompt treatment of infections
Safe sexual practices to avoid STIs
Avoiding heavy lifting that strains the abdominal wall
When to See a Doctor
You should consult a doctor if you notice:
Sudden or persistent scrotal swelling
Pain or redness in the scrotum
Fever or signs of infection
Swelling that increases with time
Centers like Sparsh Diagnostic Centre offer expert consultation and diagnostic facilities for accurate diagnosis and prompt treatment.
Hydrocele in Infants vs Adults
| Feature | Infants | Adults |
|---|---|---|
| Cause | Congenital (failure of closure) | Injury, infection, tumor |
| Symptoms | Swelling, fluctuation | Swelling, heaviness, discomfort |
| Treatment | Observation, surgery if persistent | Surgery, aspiration in some cases |
| Recovery | Fast with minimal complications | Slightly longer, requires follow-up |
Hydrocele and Fertility
While hydroceles themselves typically do not affect fertility, secondary hydroceles may arise due to conditions that impair testicular function, such as:
Infections like epididymitis
Testicular tumors
Hence, evaluation is important if fertility is a concern.
