Hydrocele

A hydrocele is a fluid-filled sac around the testicle that causes swelling in the scrotum. It's typically painless but can be uncomfortable.

Symptoms
- Swelling in the scrotum
- Heaviness or discomfort
- Translucent appearance of the scrotum when light is shined through it

Risk Factors
- Common in newborns and men over 40
- Linked to scrotal injuries or infections
- Congenital issues in infants

Types
1. Communicating Hydrocele: Fluid flows between the abdomen and scrotum.
2. Non-Communicating Hydrocele: Fluid trapped in the scrotum, often after injury or inflammation.
3. Congenital Hydrocele: Present at birth, usually resolves on its own.
4. Acquired Hydrocele: Develops later due to injury, infection, or other conditions.

Treatment:  
- Observation: Often resolves on its own, especially in infants.
- Surgery (Hydrocelectomy): For persistent or large hydroceles.
- Aspiration: Fluid drainage, though less common.
