Hydroceles generally don’t pose any threat to the testicles. They’re usually painless and disappear without treatment. However, if you have scrotal swelling, see your doctor to rule out other causes that are more harmful such as testicular cancer.



Hydrocele repair involves the drainage of a fluid collection around the testicle, and repair of the resulting defect in the fluid sac surrounding the testicle to prevent further accumulation of fluid.

How is it done?

Under a general anaesthetic, a cut is made in the scrotum and the fluid drained. The sac of the hydrocele is either bunched up on itself or turned inside-out to prevent recurrence. After stopping any small bleeding points, the incision is closed with absorbable stitches.

Why is it done?

To alleviate the troublesome symptoms of a hydrocele, such as pain, discomfort, awkwardness and difficulty with certain physical activities, or embarrassment due to a visible swelling through clothes.

What are the possible complications?

Occasionally there may be a recurrence of fluid collection (approximately 5%), a blood collection around testes which resolves slowly (haematoma), and possible infection in the skin wound or testis, requiring further treatment.

After the operation

After your operation, you will spend a period of time in the recovery area then go back to the ward. You will be able to go home once you have passed urine and have fully recovered from your anaesthetic (ie day case procedure). there will be a local anaesthetic block in the scrotal area which means that things will generally be 'numb' for over 6 hours, and sometimes into the next day.

What should I do after my procedure and when can I go back to work/resume normal activities?

You will not be able to drive for 24 hours after your anaesthetic, so you will need someone to come and collect you. You can resume most normal activities the following day but we would recommend that you do not drive your car for 2 days and refrain from sporting activities for 2 weeks. The stitches will dissolve in time. You may find it more comfortable to wear tighter briefs to support the scrotum rather than boxer shorts.

Who can I contact if there is a problem?

If there are any concerns after the operation you should contact the hospital who will arrange for one of the London Men’s Clinic team to contact you.

What follow-up will I have?

One of the London Men’s Clinic team will see you approximately 2-4 weeks after the operation to ensure that all is well and the wound has healed.
