A hydrocele is a condition that affects many men and boys, causing fluid buildup around the testicles. This common issue can lead to discomfort and concern for those experiencing it. While often harmless, understanding hydrocele is crucial for proper management and knowing when to seek medical attention.
This article delves into the basics of hydrocele, exploring its symptoms and underlying causes. It also examines various treatment options available to manage this condition effectively. By shedding light on this topic, readers will gain valuable insights to help them navigate hydrocele-related concerns with confidence and make informed decisions about their health.
The Basics of Hydrocele
A hydrocele is a fluid-filled sac that develops around a testicle, causing swelling in the scrotum. This condition results from a defect or irritation in the tunica vaginalis, the membrane surrounding the testicle. Hydroceles can also occur in the spermatic cord or the canal of Nuck.
What is a Hydrocele?
Hydroceles are classified as either communicating or noncommunicating. A communicating hydrocele is similar to a hernia, with the sac connecting the abdomen to the scrotum containing only fluid instead of abdominal contents. On the other hand, a noncommunicating hydrocele is an isolated collection of scrotal fluid, making it the most common type globally, affecting over 30 million men and boys.

Types of Hydroceles
Primary hydroceles can be further categorized into four types:
- Congenital hydrocele: Occurs when the processus vaginalis is patent and communicates with the peritoneal cavity.
- Infantile hydrocele: The processus vaginalis is obliterated at the level of the deep inguinal ring.
- Encysted hydrocele of the cord: Both the proximal and distal portions of the processus vaginalis are obliterated.
- Vaginal hydrocele: The processus vaginalis remains patent only around the testes.
Secondary hydroceles usually develop as a result of an underlying condition, such as infection (filariasis, tuberculosis of the epididymis, syphilis), injury (trauma, post-herniorrhaphy hydrocele), or malignancy.
Affected Population
Hydroceles are more common in infants than adults, with about 10% of newborn infants having a hydrocele, which often clears up without treatment within the first year. In adults, hydroceles occur in only about 1% of the population and often disappear on their own without treatment. Adult-onset hydroceles may be secondary to orchitis, epididymitis, tuberculosis, or tropical infections such as lymphatic filariasis.
Recognizing Hydrocele Symptoms
The most common symptom of a hydrocele is swelling on one or both sides of the scrotum that may feel like a water balloon. The swelling may change in size throughout the day and cause discomfort or pain in the scrotum. In some cases, the swelling may also lead to a feeling of heaviness in the groin area when sitting.
Physical Signs
A physical examination can help diagnose a hydrocele. During the exam, the healthcare provider may apply pressure to the groin area and ask the patient to cough to examine the swelling. This helps rule out inguinal hernias or testicular hernias. The provider may also shine a light through the scrotum to highlight any abdominal fluid in the area.
Associated Discomfort
While hydroceles are not typically painful, they can cause discomfort in the scrotum and groin area. The swelling may lead to a feeling of heaviness or fullness, especially when sitting or walking. In some cases, the hydrocele may grow large enough to cause pain or interfere with daily activities.

When to Seek Medical Attention
It is important to have a healthcare provider check a hydrocele, even if it is not causing pain or discomfort. Hydroceles can lead to serious complications, such as testicular cysts, tumors, or inguinal hernias. Seek medical attention if you notice any of the following symptoms:
- Swelling or a lump around the scrotum or just above it
- Evident pain in the scrotum
- Nausea and vomiting
- Decreased appetite or bowel movements
In infants, hydroceles often go away on their own within the first year of life. However, if the hydrocele persists or causes discomfort, it is important to consult a pediatrician for proper evaluation and treatment.
Underlying Causes of Hydrocele
Several factors can contribute to the development of a hydrocele, ranging from developmental issues to acquired conditions. Understanding these underlying causes is crucial for proper diagnosis and treatment.
Hydroceles are classified as either primary or secondary. Primary hydroceles are further categorized into four types based on the site of obliteration of the processus vaginalis: congenital, infantile, encysted hydrocele of the cord, and vaginal hydrocele. Congenital hydroceles occur when the processus vaginalis remains patent and communicates with the peritoneal cavity, while infantile hydroceles result from obliteration at the level of the deep inguinal ring. Encysted hydroceles of the cord develop when both proximal and distal portions of the processus vaginalis are obliterated, and vaginal hydroceles arise when the processus vaginalis remains patent only around the testes.
Secondary hydroceles, on the other hand, usually develop as a result of an underlying condition, such as infection (filariasis, tuberculosis of the epididymis, syphilis), injury (trauma, post-herniorrhaphy hydrocele), or malignancy. Filariasis, caused by the parasite Wuchereria bancrofti, is the main cause of hydroceles globally, affecting millions of people in tropical and subtropical regions. In the United States, however, iatrogenic causes, such as trauma or post-herniorrhaphy complications, are more common.
Risk factors for hydroceles include breech presentation, low birth weight, and gestational progestin use. At birth, a significant proportion of term male infants possess a patent processus vaginalis, which declines steadily over the first two years of life. However, autopsy data suggests that the processus vaginalis may remain patent in a substantial percentage of adults, although only a small fraction of these cases become clinically evident.
Management and Treatment Options
The management of hydroceles depends on the size, symptoms, and underlying cause. Treatment options range from conservative approaches to surgical interventions.
Conservative management may be appropriate for small, asymptomatic hydroceles. This involves monitoring the condition and using scrotal support or compression to alleviate discomfort. Pain medication and anti-inflammatory drugs can help manage any associated pain.

For larger or symptomatic hydroceles, surgical intervention is often necessary. The most common surgical procedure is a hydrocelectomy, which involves removing the fluid-filled sac. This can be done through a small incision in the scrotum or using a minimally invasive approach. In some cases, a procedure called sclerotherapy may be used, where a solution is injected into the sac to cause it to scar and shrink.
After treatment, proper post-treatment care is essential for optimal recovery. This includes rest, ice application, and wearing supportive undergarments. Patients should follow their healthcare provider’s instructions regarding activity restrictions and wound care. Regular follow-up appointments are important to monitor healing and check for any complications or recurrence of the hydrocele.
Conclusion
Understanding hydrocele is key to managing this common condition effectively. From its basic definition to its various types, symptoms, causes, and treatment options, this article has provided a comprehensive overview. By recognizing the signs and knowing when to seek medical attention, individuals can take proactive steps to address hydrocele concerns.
While hydroceles often resolve on their own, especially in infants, some cases may require medical intervention. The range of treatment options, from conservative management to surgical procedures, offers solutions tailored to each patient’s needs. Regular check-ups and open communication with healthcare providers are crucial to ensure proper care and timely treatment of hydrocele, promoting overall testicular health and well-being.
