Epididymal cyst surgery is not normally needed in most men. These cysts are usually benign and can simply be observed if they are small and painless.
Surgery, called epididymal cyst excision, is usually considered only when the cyst causes:
- Persistent pain or discomfort
- A large or increasing swelling affecting daily life
- Infection or diagnostic uncertainty
- Occasionally fertility concerns related to the cyst itself
The usual operation is a small incision in the scrotum to remove the cyst. It is commonly done as a day-case procedure, often under general or local anaesthesia. Campbell-Walsh Urology advises surgical treatment only for discomfort, infection, disability from size, or infertility, and describes a trans-scrotal approach. Campbell-Walsh Wein Urology, p. 2464.
Before surgery, a
scrotal ultrasound is often used to confirm that it is a cyst arising from the epididymis and not a testicular mass.
NHS referral guidance similarly notes that these cysts rarely require treatment and recommends referral mainly when symptoms significantly affect quality of life.
Important: surgery can sometimes damage the epididymis or sperm pathway. This may affect fertility, particularly if you are trying to have children or have cysts on both sides. Discuss sperm preservation and fertility risk with a urologist before agreeing to surgery.
Seek urgent assessment if there is sudden severe testicular pain, a hard lump in the testicle, fever, redness, or rapid enlargement.
