Hydrocele
A hydrocele is a fluid collection around the testicle. It often causes painless scrotal swelling.
Symptoms
Painless scrotal swelling or heaviness, usually unilateral.
Causes and risk
Secondary hydrocele can result from injury, infection, or epididymitis. Primary hydrocele in adults is often idiopathic.
How it is evaluated
Physical exam and scrotal ultrasound are used to confirm the diagnosis and rule out other causes.
Treatment
Treatment depends on size, symptoms, and cause. Small asymptomatic hydroceles can be observed. Larger ones may require aspiration or surgery.
When to seek care
Seek care for acute scrotal swelling with pain, fever, or rapid growth.
