Blood in Urine: Causes and Concerns for Patients

Could you please provide more details about the issue of hematuria?

1.
I previously experienced dark yellow urine with a reddish tint after holding it overnight, and after urinating, I felt something unusual in my bladder.
However, my urine returned to normal afterward.
A month later, after jogging a bit longer than usual, I noticed blood in my urine, but it returned to normal after drinking more water.
There was no pain before or after urination, but for 2 to 3 days, I felt a brief, sharp, warm sensation in my bladder that lasted no more than 5 seconds, occurring only a few times a day.
I have noticed that the blood in my urine typically occurs when I have the urge to urinate, but the volume is low.
When I push to urinate, I sometimes see blood, though this is infrequent.
Occasionally, when I push, the urine color is normal, and I experience blood in my urine no more than twice a day, with most of the time being normal.
What could be the issue?
2.
I am currently being treated for hepatitis B, with liver enzyme levels at 74 and 116.
Can I take urinary medications alongside my liver medications? Will this affect my liver, or could the presence of red urine be related to my liver medication?
3.
For a kidney imaging study, I understand that a contrast agent is required, which may have side effects.
However, since I have hepatitis B and my body is relatively weak, is it safe for me to receive a contrast agent?

It is indeed quite concerning! Patients with hepatitis may sometimes have darker urine.
You must not ignore the phenomenon of "hematuria." I recommend that you visit a hospital and consult a urologist for a thorough examination.

More Info

Understanding blood in urine, or hematuria, is crucial for patients as it can indicate various underlying conditions, ranging from benign to serious. In your case, the episodes of blood in your urine, particularly after physical exertion like jogging, could be attributed to a few potential causes.

1. Physical Activity and Hematuria: The occurrence of blood in your urine after running may suggest a condition known as "exercise-induced hematuria." This is not uncommon and can happen due to the impact of running on the bladder and kidneys, leading to minor injuries or irritation. The fact that your urine returned to normal after hydration is a positive sign, indicating that the hematuria may have been transient and related to your physical activity rather than a chronic issue.

2. Bladder Irritation: The "strange" feeling in your bladder after holding your urine overnight could indicate irritation. Holding urine for extended periods can lead to bladder distension and irritation, which may cause temporary discomfort or changes in urine color. If you experience this sensation frequently, it may be worth discussing with a healthcare provider to rule out any underlying bladder issues.

3. Infection or Inflammation: The brief episodes of a "stinging" sensation in your bladder could suggest a mild urinary tract infection (UTI) or inflammation. UTIs can cause hematuria and discomfort, especially if they are mild and resolve quickly. If you notice persistent symptoms or worsening of your condition, it would be wise to seek medical evaluation.

4. Liver Health and Medication Interactions: Regarding your treatment for hepatitis B and the use of urinary medications, it is essential to consult your healthcare provider. Some medications can have interactions with liver function, especially if your liver enzymes are elevated. Your doctor can provide guidance on whether the urinary medications you are considering are safe in conjunction with your hepatitis B treatment.

5. Imaging and Contrast Agents: When it comes to kidney imaging that requires contrast agents, it is crucial to discuss your hepatitis B status with your healthcare provider. Some contrast agents can pose risks, especially in patients with liver disease. Your doctor will assess your overall health and liver function before recommending any imaging studies involving contrast.

In summary, while your symptoms may not indicate a severe underlying condition, it is essential to monitor them closely. If you experience recurrent hematuria, persistent bladder discomfort, or any new symptoms, you should seek medical attention for further evaluation. A healthcare provider can perform necessary tests, such as urinalysis or imaging studies, to determine the underlying cause and provide appropriate treatment. Additionally, always consult your doctor regarding any new medications or treatments, especially considering your existing liver condition.
