What Is the Difference Between Hydrocele and Varicocele?

A hydrocele is a collection of fluid around the testicle, while a varicocele is an enlargement of the veins within the scrotum. Both can cause scrotal swelling, but their causes, physical findings, and treatment approaches are different.

Although hydrocele and varicocele can both cause swelling or changes in the scrotum, they involve different structures.

Hydrocele:

• Caused by excess fluid collecting around the testicle
• Usually appears as smooth scrotal swelling
• Often painless
• May cause heaviness or discomfort when it becomes large
• Persistent symptomatic cases may be treated with hydrocelectomy

Varicocele:

• Involves enlarged veins around the testicle
• More commonly occurs on the left side
• May cause a dull aching discomfort, particularly after standing or physical activity
• Can sometimes be associated with abnormal sperm production or fertility concerns
• Treatment depends on symptoms, fertility considerations, and testicular findings

A physical examination can often provide important clues, but scrotal ultrasound with Doppler may be recommended when the diagnosis is uncertain or both conditions need to be distinguished.

At SCI International Hospital, Dr. Vishal Dutt Gour evaluates scrotal swelling carefully to determine whether it is caused by hydrocele, varicocele, or another condition. When required, appropriate imaging is used to support an accurate diagnosis and guide treatment.
