Inflammation of the epididymis; commonly caused by a UTI and is the most common cause of which symptom?

• A. Epididymitis
• B. Orchitis
• C. Prostatitis
• D. Hydrocele

Answer: (A)

Inflammation of the epididymis is epididymitis, typically arising from a urinary tract infection. In adults, the symptom most commonly caused by this condition is acute scrotal pain, often with swelling and tenderness. The option that corresponds to the condition itself best fits the stem because epididymitis is the usual source of that scrotal pain. Orchitis involves the testicle and can cause pain but is not the most common source of acute scrotal pain; prostatitis presents with urinary and perineal symptoms rather than primarily scrotal pain; a hydrocele causes swelling that is usually painless. So epididymitis is the best match for the symptom described.
