Hydrocele Surgery at Oaks Hospital in Colchester

Hydrocele surgery is a straightforward procedure used to remove the fluid-filled sac around your testicle that causes swelling in your scrotum. It is one of the most effective treatments for this common and highly treatable condition. 

At Ramsay Health Care, hydrocele surgery is carried out by experienced consultant urologists who specialise in scrotal and testicular conditions, ensuring you receive expert, personalised care from your very first appointment.

Most hydrocele repairs are performed as a day-case procedure, meaning you can go home the same day with clear guidance on recovery and follow-up. Our modern, CQC-rated hospitals, low infection rates and dedicated surgical teams provide a safe, comfortable environment for your treatment.

If you’re experiencing swelling, discomfort or uncertainty about a hydrocele, you can book an appointment or make an enquiry with a Ramsay urology specialist to discuss your options and plan the right treatment for you.

What is a hydrocele?

A hydrocele is a build-up of fluid in your scrotum, creating a smooth swelling around one or both testicles. The fluid collects within the tunica vaginalis, the thin protective sac that surrounds each testicle. Many people describe the swelling as feeling like a water-filled balloon or a sense of heaviness in the scrotum.

There are two main types:

• Communicating hydrocele - the sac remains connected to your abdominal cavity, allowing fluid to move in and out. This can cause the swelling to change size, often becoming larger during the day.

• Non-communicating hydrocele - the sac is closed, but fluid still accumulates because it is produced faster than it can be absorbed.

Hydroceles are primarily:

• Congenital - present from birth when the channel between your abdomen and scrotum doesn’t fully close.

• Acquired - develop later in life, often due to injury, infection, inflammation, or changes in fluid production and drainage.

Although hydroceles are usually harmless, they can resemble other scrotal conditions such as inguinal hernias, epididymal cysts or varicoceles, so proper assessment is important.

Symptoms of hydrocele

Hydroceles often cause:

• Painless scrotal swelling, often described as swollen testicles, usually smooth and fluid-filled

• A feeling of heaviness or dragging sensation

• Discomfort if the swelling becomes large

• Fluctuating swelling size, especially with communicating hydroceles

• Pain, which is uncommon but may occur if there is infection or significant tension in the sac

Any new scrotal swelling should be checked, even if it is painless.

Diagnosis of hydrocele

Diagnosing a hydrocele is usually simple and straightforward.

• Physical examination - a clinician gently examines your scrotum to assess the swelling.

• Transillumination test - a light is shone through your scrotum; fluid allows light to pass through, helping distinguish a hydrocele from other lumps.

• Ultrasound scan - is used to confirm the diagnosis and rule out other causes such as hernias, cysts or testicular tumours.

When urgent assessment is needed

Seek urgent medical attention if you experience:

• Sudden, severe scrotal pain

• Rapid swelling

• Fever or signs of infection

• A very tender scrotum

These symptoms may indicate infection or testicular torsion, which requires immediate care.

Do you need hydrocele surgery?

Not everyone with a hydrocele needs surgery. Treatment depends on the size of your hydrocele, your symptoms, and whether it is likely to resolve on its own. A Ramsay consultant will assess your individual case and recommend the safest, most appropriate approach.

When surgery is recommended

Surgery may be advised if your hydrocele is:

• Causing discomfort or pain

• Significantly large or growing, affecting daily activities or quality of life

• Cosmetically concerning or causing embarrassment

• Persistent and not resolving on its own (common in adults)

• Has an uncertain diagnosis, where another condition needs to be ruled out

• Associated with complications, such as infection or pressure on surrounding structures

When watchful waiting is appropriate

Monitoring without surgery may be suitable if:

• Your hydrocele is small and not causing symptoms

• It occurs in infants, as many congenital hydroceles resolve naturally by age 1 to 2

Your consultant will guide you on whether observation or surgery is the best option.

Types of hydrocele surgery

Ramsay Health Care offers several surgical approaches. Your consultant will recommend the most suitable option based on your type of hydrocele, its size, and your overall health.

Hydrocelectomy (standard open surgery)

This is the most common and effective treatment for hydroceles. It is preferred for most adult hydroceles due to its low recurrence rate and long-term success.

A small incision is made in your scrotum or lower abdomen. The fluid is drained, and the tunica vaginalis sac is removed or repaired to prevent recurrence. This surgery typically takes 45 to 60 minutes.

Aspiration and sclerotherapy

This is a less invasive alternative that may be suitable for selected patients. 

During the procedure, a needle is used to drain the fluid from your hydrocele, and a sclerosant is then injected to help seal the sac and reduce the chance of the fluid returning. 

It is usually performed under local anaesthetic and can be a useful option when standard surgery is not appropriate or when a temporary solution is needed. However, it has a higher recurrence rate than hydrocelectomy and is not typically considered a first-line treatment.

Laparoscopic approach

A laparoscopic approach offers a minimally invasive option for specific cases, particularly for communicating hydroceles or when the repair is carried out alongside another procedure. 

The surgeon makes small keyhole incisions and uses a camera-guided technique to repair your hydrocele from within the abdomen. This method may be available at selected Ramsay hospitals depending on consultant expertise.

Your Ramsay surgeon will explain which approach is most appropriate for your hydrocele, considering its type, size and your individual needs.

What happens during hydrocele surgery?

Before surgery

You will attend a pre-operative assessment, where your medical history, medications and any necessary tests are reviewed. You’ll receive clear instructions on:

• Fasting requirements

• Medication adjustments, including blood thinners

• What to bring and how to prepare

• Arranging transport home, as you won’t be able to drive after anaesthesia

You can find more information on before your stay here.

During the procedure

• You will receive either general anaesthetic (asleep) or spinal anaesthetic (numb from the waist down)

• Your surgeon makes a small incision, drains the fluid and repairs or removes the sac

• The procedure usually lasts 45 to 60 minutes

• Most hydrocele surgeries are day-case procedures, meaning you go home the same day

Immediate recovery

After surgery:

• You’ll spend time in the recovery room while the anaesthetic wears off

• Pain relief will be provided

• You can usually go home a few hours after surgery

• You’ll be discharged once you are comfortable, mobile and able to eat and drink

Recovery after hydrocele surgery

First 24 to 48 hours

• Expect swelling, bruising and mild discomfort

• Rest at home and avoid strenuous activity

• Use prescribed pain relief as needed

• Apply ice packs (wrapped in a cloth) to reduce swelling

• Keep your wound clean and dry

First week

• Avoid heavy lifting, strenuous exercise and driving until advised

• You can return to light activities as you feel able

• Showering is usually allowed after 24 to 48 hours, but avoid soaking your wound

• Contact the clinic if you develop fever, increasing pain, redness or discharge

2 to 6 weeks

• Gradually return to normal activities

• Most people resume exercise after 3 to 4 weeks

• Sexual activity is usually safe after 2 to 3 weeks, depending on comfort

• Full recovery is typically expected within 4 to 6 weeks

• A follow-up appointment will be arranged to check healing

What to wear after hydrocele surgery

Wearing the right support can make a big difference to comfort and healing. Choose snug-fitting briefs or an athletic support, avoiding loose boxers initially, as they allow too much movement. Wear supportive underwear for 2 to 4 weeks as the support they offer helps reduce swelling and protects the surgical area.

Testicle size after hydrocele surgery

Many patients worry about their testicle size after hydrocele surgery, especially if they have experienced swollen testicles before the procedure. It’s completely normal to feel anxious about how the area will look during recovery. Immediately after your operation, your testicle and surrounding tissues are often swollen, which can make your scrotum appear larger than before. This swelling is temporary and part of the normal healing process.

Over the next two to four weeks, the swelling gradually reduces as the tissues settle. Most people notice steady improvement during this period. By around four to six weeks, your testicle usually returns to its normal size, and in most cases, it will match the other testicle once healing is complete. Some mild residual swelling can persist a little longer, especially after activity, but this continues to improve with time.

You should seek advice if the swelling increases after the first few days, if there is a persistent size difference that does not improve, or if you develop redness, heat, fever or worsening pain. These symptoms may indicate an issue that needs review. 

Your Ramsay consultant will discuss what to expect at each stage of recovery and will check your progress at your follow-up appointment, where any concerns about size or healing can be addressed.

Risks and complications of hydrocele surgery

Hydrocele surgery is generally very safe, especially when performed by experienced surgeons in a high-quality clinical environment. Most patients experience only minor, short-term effects such as bruising, swelling and temporary discomfort. Some tenderness around the wound site is also common in the first few days.

More significant complications are uncommon, and Ramsay’s surgical teams follow strict infection-control standards to keep risks as low as possible. Your consultant will explain the potential risks before your procedure and answer any questions you may have, ensuring you feel informed and reassured throughout your care.
