What is a hydrocele repair? 

A hydrocele is a collection of fluid around the testicle. Surgery for a hydrocele involves removing or repairing the fluid sac surrounding your testicle to prevent the fluid from coming back. This is usually done under general or spinal anaesthetic. The surgeon makes a small incision in the scrotum, drains the fluid, and closes or removes the sac using absorbable stitches. After surgery, your testicle may feel bulkier than it did before, which is normal.  

What to expect after the procedure  

After the operation, you can expect some swelling, bruising, and discomfort around the scrotum, which may last several days to a few weeks. Your testicle will feel larger because of the “bunched-up” sac or remaining tissue. You will be provided with scrotal support (such as a jock strap) to help with comfort, and all stitches are dissolvable, disappearing within two to three weeks. Most patients recover without major issues and may not require routine follow-up unless advised. 

Pain and recovery  

Mild pain and tenderness are common and can usually be managed with simple painkillers like paracetamol or ibuprofen. Ice packs (not directly on the skin) may help reduce swelling in the first few days. Heavy lifting and strenuous activity should be avoided for at least four weeks. While most discomfort improves steadily, increasing pain, swelling, or bruising day by day should prompt contact with your surgical team.  

How to look after yourself  

  • Wear the scrotal support or tight underwear as advised.  

  • Keep the cut clean and dry.  

  • Take pain relief as recommended.  

  • Avoid heavy lifting and strenuous exercise for four weeks.
