What is the primary indication for performing an epididymectomy?

The primary indication for performing an epididymectomy is an infection of the epididymis, known as epididymitis. In cases of severe, persistent, or recurrent epididymitis, an epididymectomy may be indicated to alleviate pain, prevent complications, and remove the source of the infection that may not respond to antibiotic treatment.

This surgical procedure allows for the targeted removal of the inflamed or infected epididymis, while preserving the testis, which is crucial for maintaining fertility and hormonal balance. The surgery can effectively resolve symptoms such as pain and swelling when medical management fails, making it a necessary intervention for patients suffering from chronic or complicated cases of epididymitis.

In contrast, conditions like testicular torsion require immediate surgical intervention to save the testis, and varicocele treatment focuses on correcting issues with venous drainage in the scrotum. The surgical removal of the testis is a more drastic measure reserved for malignancies or severe trauma and is not directly related to an infection of the epididymis. Thus, the specific need to address significant infection and its complications makes an epididymectomy the appropriate choice in this context.
