## **Core Concept**
The patient's symptoms and positive transillumination test suggest a hydrocele, which is an accumulation of serous fluid in a body cavity, particularly in the tunica vaginalis testis or along the spermatic cord. This condition often presents as a scrotal swelling. The key principle here is to understand the nature of hydroceles and their management.

## **Why the Correct Answer is Right**
The preferred treatment for a large hydrocele, especially when it causes significant symptoms or cosmetic issues, is surgical intervention. **Lord's procedure** or **Jaboulay's procedure** are commonly performed for hydrocele repair. However, the most straightforward and commonly recommended surgical approach for a large hydrocele is **Jaboulay's procedure**, also known as eversion of the sac. This involves everting the hydrocele sac through a small scrotal incision, which helps to prevent reaccumulation of fluid.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is blank and cannot be evaluated.
- **Option B:** This option is also blank and does not provide any information for evaluation.
- **Option D:** Similarly, this option is blank and lacks details for assessment.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that a hydrocele can be diagnosed by transillumination, which involves shining a light through the scrotum; fluid-filled structures like hydroceles will transilluminate, whereas solid masses will not. This simple test can help differentiate hydroceles from other causes of scrotal swelling like epididymitis or testicular tumors.

## **Correct Answer:** . Jaboulay's procedure
