Blood in Urine: Possible Causes and Solutions - Urology

Share to:

Please consult Dr. Chen?


I have been masturbating (about four times a week) for the past two years.
Earlier this year, I experienced bleeding after ejaculation while using a masturbator.
I visited a doctor who prescribed antibiotics, and after taking them for a week, I didn't have any issues for about two months.
However, in the past two weeks, after manually masturbating, I noticed bleeding again.
Now, it seems that whenever I have an erection (without masturbating), I experience bleeding when I need to urinate.
What could be the possible cause of this?

More Info


Blood in urine, or hematuria, can be alarming and may indicate a variety of underlying conditions. In your case, the occurrence of blood after masturbation, particularly when it has recurred after a period of absence, raises several potential concerns that should be evaluated by a healthcare professional.


Possible Causes of Hematuria
1. Injury or Trauma: Engaging in vigorous sexual activity or masturbation can sometimes lead to minor injuries in the genital area or urinary tract, which may result in bleeding. This is especially true if there is excessive friction or if a foreign object (like a sex toy) is used improperly.

2. Infection: Urinary tract infections (UTIs) can cause hematuria. Symptoms may include a burning sensation during urination, frequent urination, and lower abdominal pain. Although you mentioned having taken antibiotics previously, it’s possible that an infection could recur or that a different type of infection could be present.

3. Inflammation: Conditions such as prostatitis (inflammation of the prostate gland) or urethritis (inflammation of the urethra) can also lead to blood in the urine. These conditions can be caused by infections or other irritants.

4. Kidney Stones: The presence of kidney stones can cause bleeding, especially if they irritate the lining of the urinary tract. If you have a history of kidney stones, this could be a relevant factor.

5. Vascular Issues: Blood vessel abnormalities or ruptures in the urinary tract can lead to bleeding. This could be due to increased pressure during sexual activity or other factors.

6. Tumors or Growths: While less common, tumors in the bladder, kidneys, or prostate can cause hematuria. This is particularly concerning if the bleeding is persistent or associated with other symptoms.


Recommended Actions
1. Consult a Urologist: Given the recurrence of blood in your urine, it is crucial to consult a urologist. They can perform a thorough evaluation, including a physical examination, urinalysis, and possibly imaging studies like an ultrasound or CT scan to identify any underlying issues.

2. Urinalysis and Culture: A urinalysis can help determine if there are signs of infection, blood, or other abnormalities. A urine culture can identify specific bacteria if an infection is suspected.

3. Avoid Irritants: Until you have a clear diagnosis, it may be wise to avoid activities that could irritate the urinary tract, such as vigorous sexual activity or the use of certain sexual aids.

4. Hydration: Staying well-hydrated can help flush out the urinary system and may alleviate some symptoms if they are related to irritation or infection.

5. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as pain, changes in urination frequency, or any other unusual signs. This information will be helpful for your healthcare provider.


Conclusion
Blood in urine can arise from various causes, ranging from benign to serious conditions. Given your history and the recurrence of symptoms, it is essential to seek medical attention promptly. A urologist will be able to provide a comprehensive evaluation and appropriate treatment based on the underlying cause of your hematuria. Early diagnosis and intervention are key to managing any potential health issues effectively.
