Suspected urethritis with urinary tract pain but no bacteria detected?

Hello Doctor, around the end of February this year, after masturbating, I felt some discomfort in my urethra (I have no sexual experience).
At that time, I didn't feel any stinging sensation when urinating, but later that night, I started to experience a stinging pain when I went to the bathroom.
Eventually, the pain became severe, and I began to experience frequent urination, nocturia, but no hematuria or discharge from the urethral opening.
After four days, I went to a clinic for a urinalysis, and the doctor said there were no bacteria.
An ultrasound was performed, and there were no stones.
I then visited a second clinic, and the results were the same.
The doctor asked if I had any pain in the perineum, to which I replied yes.
The doctor then suspected I might have prostatitis.
Initially, I only had pain in the urethra, but later, due to possibly delayed treatment, I developed swelling and pain near the perineum and anus, along with a slight fever (or could it be that masturbation caused the prostatitis, and I just didn't realize it?).
I then went to a third clinic for another urinalysis, which again showed no bacteria.
The doctor prescribed an antibiotic called levofloxacin, but after taking it for almost two weeks, I saw little improvement.
I then went to a fourth clinic for another urinalysis, which also showed no bacteria, and the doctor prescribed a self-paid antibiotic, ciprofloxacin 500 mg.
After taking it for just one day, the pain significantly decreased, and I felt like I was improving.
Now, the prostatitis pain is gone, but I still have slight pain in the urethra, which is also improving.

Could there be some bacteria that are not detectable in the tests? Since no bacteria were found, why is the antibiotic effective? What are the differences between these two antibiotics? If ciprofloxacin is effective, what type of bacteria could it be targeting? The effectiveness seems to vary greatly.
Am I dealing with urethritis or prostatitis, or could the bacteria have entered the prostate during masturbation, leading to prostatitis? I have heard that frequent masturbation can lower the resistance of the urethra.
How long should I take ciprofloxacin, considering I actually started taking it the day after my visit? Thank you, Doctor Du, for listening to my lengthy concerns; I truly appreciate it.

Hello: If the bacterial count is low, it cannot be cultured, and some bacteria are difficult to culture, making it hard to identify the specific type (such as Gram-negative bacteria or spirochetes, etc.).
However, most are sexually transmitted.
It is not necessarily the last medication that is effective; rather, it is the medications taken over the previous doses that have had an effect.
However, you should not stop taking the medication casually; a duration of 4-6 weeks is generally required (according to your treating physician).
Pay attention to your lifestyle, diet, and practice safe sex.
As for urethritis or prostatitis, a hospital diagnosis is necessary; this platform cannot provide a diagnosis without examination.
(There are not many oral medication options, but they are generally effective; however, some individuals may respond well while others may take longer.)

More Info

Unexplained urethral pain can be a complex issue, often requiring a thorough understanding of potential causes and appropriate treatment options. Based on your description, it seems you have been experiencing significant discomfort, which has led to multiple visits to healthcare providers and various treatments. Let's break down your situation and address your concerns regarding antibiotic effectiveness, potential diagnoses, and the implications of your symptoms.

Understanding Your Symptoms
Initially, you experienced discomfort after masturbation, which progressed to sharp pain during urination, frequent urination, and some systemic symptoms like fever. The absence of bacteria in your urine tests is noteworthy, as it suggests that a typical urinary tract infection (UTI) may not be the cause of your symptoms.

Possible Causes
1. Non-bacterial Prostatitis: This condition can cause similar symptoms to bacterial prostatitis but does not involve a bacterial infection. It can be triggered by various factors, including stress, pelvic floor dysfunction, or even irritation from sexual activity.

2. Urethritis: Inflammation of the urethra can occur without a detectable bacterial infection. This could be due to irritation, trauma, or other non-infectious causes.

3. Chronic Pelvic Pain Syndrome: This syndrome encompasses a range of symptoms, including pain in the pelvic region, urinary symptoms, and sexual dysfunction, without a clear infectious cause.

Antibiotic Effectiveness
You mentioned that you were prescribed levofloxacin and ciprofloxacin, both of which are fluoroquinolone antibiotics. These medications are typically effective against a range of bacteria, including those that may not be easily detected in standard urine cultures.
1. Undetected Bacteria: It's possible that your symptoms are due to a bacterial infection that is not easily identified through standard testing. Some bacteria may require specific culture conditions or may be present in low quantities that standard tests do not detect.

2. Antibiotic Response: The fact that ciprofloxacin provided relief suggests that there may be a bacterial component to your condition, even if it was not identified in testing. This could indicate a resistant strain or a type of infection that is not routinely screened for.

Differences Between Levofloxacin and Ciprofloxacin
While both levofloxacin and ciprofloxacin belong to the same class of antibiotics, they have different pharmacokinetics and spectra of activity. Ciprofloxacin is often used for urinary tract infections and has a broader spectrum against certain Gram-negative bacteria. Levofloxacin, on the other hand, is generally considered to have better efficacy against some Gram-positive bacteria and may be preferred for respiratory infections.

Duration of Treatment
The duration of antibiotic treatment can vary based on the severity of the infection and the clinical response. For uncomplicated urinary tract infections, a typical course might last 3-7 days, while more complicated cases, such as prostatitis, may require longer treatment, often 2-4 weeks. Since you started ciprofloxacin recently, it would be advisable to continue it for at least 7-14 days, depending on your response and the guidance of your healthcare provider.

Recommendations Moving Forward
1. Follow-Up: Continue to monitor your symptoms closely. If you experience any worsening or new symptoms, seek medical attention promptly.

2. Further Testing: If symptoms persist despite antibiotic treatment, consider discussing further diagnostic options with your healthcare provider. This may include imaging studies or referral to a urologist for specialized evaluation.

3. Lifestyle Modifications: Maintain good hydration, avoid irritants (such as caffeine and alcohol), and practice safe sexual behaviors to minimize irritation and potential infections.

4. Communication with Your Doctor: Be proactive in discussing your symptoms and treatment options with your healthcare provider. If you feel that your concerns are not being addressed, seeking a second opinion may be beneficial.

In conclusion, while your symptoms are challenging, understanding the potential causes and treatment options can help you navigate your healthcare journey more effectively. Always consult with your healthcare provider for personalized medical advice tailored to your specific situation.
