Blood in Urine: Causes, Risks, and Duration

The issue of hematuria?

1.
The sudden occurrence of hematuria (bright red) led me to visit a clinic for an X-ray and ultrasound, where a stone (0.4 cm) was detected in a higher position.
I would like to know if this could cause hematuria? 2.
Is there a possibility of bladder cancer? 3.
How long might hematuria last (today is the second day), and I have noticed that the color is becoming lighter?

There are many causes of hematuria, but the primary concern is the possibility of bladder cancer.
This requires repeated treatment and follow-up examinations, and the treatment plan will be arranged based on the results of these follow-ups.
If the doctor strongly suspects the possibility of cancer, they may even arrange for hospitalization for further testing.
We need to determine whether you have any stones and what the cause of the hematuria is, which should be closely monitored in the outpatient setting.
Although your age makes the likelihood of cancer low, no doctor would dare to make any guarantees.

More Info

Blood in urine, or hematuria, can be alarming and is often a sign of an underlying issue that needs to be addressed. In your case, the sudden appearance of bright red blood in the urine, along with the discovery of a kidney stone (0.4 cm), raises several important considerations.

1. Kidney Stones and Hematuria: Yes, the presence of a kidney stone can definitely cause blood in the urine. When a stone moves through the urinary tract, it can irritate the lining of the urinary system, leading to bleeding. This is particularly true if the stone is located in the kidney or ureter, as it can cause significant trauma to the tissues. The blood may appear bright red due to fresh bleeding, which is often more visible than older blood that may appear darker.

2. Risk of Bladder Cancer: While the presence of blood in the urine can be associated with bladder cancer, especially in older adults or those with risk factors (such as smoking or a history of chemical exposure), it is less common in younger individuals. In your case, given the presence of a kidney stone, it is more likely that the hematuria is related to the stone rather than cancer. However, if the blood persists or if there are other symptoms (such as pain, frequent urination, or changes in urinary habits), further evaluation may be warranted to rule out other serious conditions.

3. Duration of Hematuria: The duration of hematuria can vary depending on the underlying cause. In cases related to kidney stones, blood in the urine may resolve as the stone passes or if the irritation subsides. If you notice that the blood is becoming lighter in color, this may be a positive sign that the bleeding is decreasing. However, if the hematuria persists beyond a few days, or if you experience worsening symptoms (such as increased pain, fever, or difficulty urinating), it is crucial to seek medical attention promptly.

In summary, while kidney stones are a common cause of hematuria, it is essential to monitor the situation closely. If the blood in your urine continues or if you develop new symptoms, it is advisable to follow up with a healthcare provider for further evaluation. They may recommend imaging studies or additional tests to ensure that there are no other underlying issues that need to be addressed. Staying hydrated and managing any pain or discomfort is also important during this time.
