Hematuria

Hello doctor, I have been experiencing a problem for the past ten days.
After an erection, I notice blood in my urine, along with blood clots that are soft and pass through the urethra.
There have also been instances of blockage.
However, after that, when the penis is in a normal state, my urine appears normal.
I visited a clinic, but the doctor could not find any blood.
Could you please explain what might be happening? I work night shifts in a labor-intensive job; could this be related? (This occurs after a normal erection, with no sexual activity or masturbation.)

Doctor, what could be the cause of my condition? A: Blood in urine after an erection is a rare occurrence and has been reported in literature to be associated with venous engorgement of the prostate.
However, given your age, the primary concern should be to rule out bladder cancer.
Could my night shift work be related to this? A: I recommend monitoring whether the bleeding consistently occurs after your night shift labor.

More Info

Blood in urine, or hematuria, can be a concerning symptom for many individuals, particularly for men. It can arise from various causes, and understanding these causes is crucial for determining the appropriate course of action. In your case, experiencing blood in urine after an erection, along with the presence of blood clots, warrants careful consideration.

Possible Causes of Hematuria
1. Urinary Tract Infection (UTI): UTIs are a common cause of hematuria and can lead to inflammation of the bladder and urethra. Symptoms may include burning during urination, frequent urination, and sometimes fever. However, your description of blood only occurring after an erection suggests that a UTI may not be the primary cause.

2. Trauma or Injury: Given that you mentioned working a labor-intensive job, it’s possible that physical strain or trauma to the pelvic area could cause bleeding. Activities that involve heavy lifting or straining can lead to micro-tears in the urinary tract.

3. Urethral Injury: The presence of blood during urination after an erection could indicate a potential injury to the urethra. This could be due to vigorous activities or even friction during an erection. If the urethra is irritated or injured, it may bleed, especially when pressure is applied during urination.

4. Prostate Issues: Conditions affecting the prostate, such as prostatitis (inflammation of the prostate) or benign prostatic hyperplasia (BPH), can also lead to hematuria. These conditions are more common in older men but can occur at any age.

5. Kidney Stones: Stones in the urinary tract can cause bleeding as they move through the ureters or urethra. This is often accompanied by severe pain, but not always.

6. Vascular Issues: Conditions affecting blood vessels in the urinary tract can lead to bleeding. This could be due to conditions like arteriovenous malformations or other vascular anomalies.

When to Seek Medical Attention
Given that you have experienced this symptom for ten days, it is essential to seek medical attention if you haven’t already. A healthcare provider can perform a thorough evaluation, which may include:
- Urinalysis: Testing your urine can help identify the presence of blood, infection, or other abnormalities.

- Imaging Studies: Ultrasounds or CT scans can help visualize the kidneys, bladder, and urethra to identify any stones, tumors, or structural issues.

- Cystoscopy: This procedure allows a doctor to look inside the bladder and urethra using a thin tube with a camera.

Conclusion
While it is possible that your labor-intensive job may contribute to your symptoms, it is crucial to rule out more serious conditions. Blood in urine, especially when accompanied by clots, should not be ignored. It is advisable to consult a urologist or a healthcare provider specializing in urinary tract issues for a comprehensive evaluation and appropriate management. Early diagnosis and treatment can help prevent potential complications and ensure your overall health and well-being.
