Persistent Hematuria: What It Means for Your Kidney Health - Urology

Regarding urinary occult blood?


Last year, around May to June, I had a urinalysis that showed a positive reaction for hematuria.
In November, I had another urinalysis and consulted a urologist who performed an X-ray and told me there were no stones, and it might just be microvascular bleeding.
In late June of this year, I had another urinalysis, and it still showed hematuria.
Given that I have had three urinalyses over the course of a year, all showing hematuria but no other abnormalities, could this indicate a kidney issue? All three tests showed hematuria at a trace level (1+).
Additionally, I have hypertension; my previous measurement was 144/95, and I am currently taking antihypertensive medication to manage it.

You can visit the outpatient clinic for a urinalysis and ultrasound examination.
If further investigation is needed, it may include cystography and renal imaging.

Persistent hematuria, or the presence of blood in the urine, can be a concerning symptom that may indicate underlying kidney or urinary tract issues. Given your history of recurrent hematuria over the past year, it is essential to understand what this could mean for your kidney health and the necessary steps to take.

Firstly, hematuria can originate from various sources within the urinary system, including the kidneys, ureters, bladder, and urethra. In your case, since you have had three urine tests over the span of a year, all showing a positive reaction for hematuria but without any other significant findings, it suggests that there may be a persistent issue that requires further investigation.

The fact that your hematuria has been classified as "1+" indicates a low level of blood in the urine. While this may not seem alarming, it is crucial to consider the context. Persistent hematuria can be associated with several conditions, ranging from benign causes, such as exercise-induced hematuria or minor trauma, to more serious conditions, including glomerulonephritis, urinary tract infections, or even tumors in the urinary tract.

Given your history of high blood pressure, it is also important to consider how this may relate to your kidney health. Hypertension can lead to kidney damage over time, and the kidneys play a crucial role in regulating blood pressure. Therefore, it is vital to manage your blood pressure effectively, as uncontrolled hypertension can exacerbate kidney issues.

In your case, since you have already consulted with a urologist and undergone imaging studies like X-rays, it is advisable to follow up with a nephrologist, a specialist in kidney health. They may recommend additional tests, such as a renal ultrasound, CT scan, or even a cystoscopy, to visualize the urinary tract and identify any potential abnormalities that may not have been detected in previous evaluations.

Moreover, it is essential to monitor any accompanying symptoms you may experience, such as changes in urine color, pain during urination, or any signs of infection, such as fever or chills. These symptoms can provide valuable information to your healthcare provider regarding the underlying cause of your hematuria.

In summary, while the presence of blood in your urine on multiple occasions is concerning, it does not automatically indicate severe kidney disease. However, it warrants further investigation to rule out any significant underlying conditions. Given your history of hypertension, managing your blood pressure and maintaining regular follow-ups with your healthcare provider is crucial for your overall kidney health. It is advisable to discuss your concerns with a nephrologist, who can guide you through the necessary diagnostic steps and potential treatment options.
