What Is the Difference Between Hydrocele and Epididymitis?

A hydrocele is a collection of fluid around the testicle, while epididymitis is inflammation of the epididymis, the tube located behind the testicle. Epididymitis commonly causes pain and tenderness, whereas a hydrocele is usually painless.

Although both conditions can cause scrotal swelling, they affect different structures and require different treatment.

Hydrocele:

• Involves fluid collecting around the testicle
• Usually causes painless swelling
• May produce heaviness or pressure when large
• May be monitored if small and asymptomatic
• Persistent symptomatic cases may require hydrocele treatment or surgery

Epididymitis:

• Involves inflammation of the epididymis
• Often causes pain and tenderness in the scrotum
• May be accompanied by redness, warmth, urinary symptoms, or fever
• Can sometimes cause a reactive hydrocele
• Treatment depends on the underlying cause and may include appropriate medication and supportive care

Because epididymitis can sometimes occur together with a hydrocele, persistent or painful scrotal swelling should be evaluated rather than diagnosed based on symptoms alone.

SCI International Hospital

At SCI International Hospital, Dr. Vishal Dutt Gour evaluates scrotal swelling, pain, and associated urinary symptoms to distinguish hydrocele from conditions such as epididymitis. When required, clinical examination and scrotal ultrasound are used to establish the diagnosis and guide treatment.
