What is the most critical examination during the diagnostic process?

Okay, let's talk about this.

What is the single most crucial test for diagnosing prostatitis?

If I had to pick the "most crucial" one, it would absolutely be the Routine Examination of Expressed Prostatic Secretions (EPS).

You can think of it as the "gold standard" or the "ace evidence" for diagnosing prostatitis.

Why is it the most crucial? An analogy will help

Imagine your prostate is like a "small workshop" that's malfunctioning.

• Ultrasound Examination: This is like looking at the workshop from the outside with a telescope. You can see its outline, size, and if there's anything strange growing (like cysts or calcifications), but you can't see what the workers (cells) inside are actually doing.
• Urinalysis: This checks if there's a problem with the "drainage pipes" (urinary tract). Sometimes workshop problems affect the pipes, but checking the pipes alone doesn't necessarily confirm the problem is with the workshop itself.
• Digital Rectal Examination (DRE): This is when the doctor uses their finger to "feel" the workshop's outer wall, checking if it's swollen, warm, or tender to the touch. This is a very important first step that provides many clues, but it still doesn't get inside the workshop.

The Routine Examination of Expressed Prostatic Secretions (EPS) is different. It involves taking a sample directly from the "workshop" (prostatic fluid) and analyzing it in the lab. This is the only way to get a direct look inside the workshop.

What does this "sample" tell us?

After obtaining the prostatic fluid, doctors mainly look for these things:

1. White Blood Cells (WBCs):

   • What they are: The body's "police cells"; they rush to wherever there's inflammation (a fight).
   • What it means: If the WBC count in the prostatic fluid is sky-high, it means there's definitely a "fight" (inflammation) happening inside the prostate "workshop". This is the most direct evidence for the presence of prostatitis.

2. Lecithin Bodies:

   • What they are: The "product" secreted by the prostate, representing how well the prostate is functioning.
   • What it means: If the number of lecithin bodies is significantly reduced, it means the workshop's production function has declined, which is also a key indicator of prostatitis.

3. Bacterial Culture (if needed):

   • What it is: "Culturing" the prostatic fluid sample to see if any "bad guys" (bacteria) grow.
   • What it means: If bacteria grow, it confirms "bacterial prostatitis" and identifies the specific bacteria, allowing for "targeted treatment" with the right antibiotics. If no bacteria grow but WBCs are high, it's most likely "non-bacterial prostatitis".

To summarize

So, you see, while doctors combine symptoms, DRE, ultrasound, and other methods for a comprehensive diagnosis, the core evidence needed to definitively "characterize" and "classify" prostatitis is still the Routine Examination of Expressed Prostatic Secretions (EPS).

• It confirms whether inflammation is present.
• It helps distinguish bacterial from non-bacterial prostatitis.
• It reflects the functional state of the prostate.

Understanding these points allows the doctor to formulate the most appropriate treatment plan for you. Therefore, although obtaining the prostatic fluid sample might be slightly uncomfortable, its value for a clear diagnosis is irreplaceable by other tests.
