### Patient: Doctor, I have been experiencing pain and swelling in my scrotum. I also have a fever and difficulty urinating. I think I may have epididymitis.
### Doctor: Based on your symptoms, we will need to conduct a few medical tests to confirm your diagnosis. We will start with a urinalysis to check for any presence of bacteria in your urine. We will also need to perform a radiographic imaging procedure to check for any inflammation and blockages in your urinary tract. An ultrasonography is also required to assess the condition of your testicles and epididymis. Additionally, a rectal examination and prostate-specific antigen measurement will be performed to rule out prostatitis. Lastly, a blood culture will also be required, and in some cases, insertion of a catheter into the urinary bladder may be necessary.
