Step-by-step explanation:
The most appropriate management for a 58-year-old male with right-sided scrotal swelling, pain, and dysuria is to consider the possibility of acute epididymitis caused by a bacterial infection. Antibiotics are generally prescribed to treat acute epididymitis, and treatment may last for several weeks to ensure complete eradication of the bacteria.
