Urinalysis


Hello, I went for a urine test after school to monitor protein levels and found 28 red blood cells along with proteinuria ++.
Since I have had intermittent proteinuria in the past, my doctor recommended ongoing monitoring.
This was the first time I tested positive for hematuria, so that evening I immediately visited the nephrology department at Tzu Chi Hospital (suspecting kidney inflammation).
Upon re-testing at the hospital, I found that the proteinuria had decreased to +/- and there was no hematuria.
The doctor said it didn't seem like kidney inflammation, and my white blood cell count was normal, so the doctor concluded that there was no issue and suggested continued monitoring.

Two weeks ago, the urology department diagnosed me with epididymitis, and after two weeks of medication, the doctor said it was almost resolved (there was a 5-day gap between the last consultation and the detection of hematuria).
Additionally, I have a hernia on the left side, and I had surgery for a hernia on the right side just two months ago.
The more I researched online, the more alarming it became, as it mentioned the possibility of bladder cancer (painless hematuria), which made me very anxious.

Could you please tell me what the chances are? For the past three weeks, I have frequently experienced localized inflammation, including paronychia, otitis media, and epididymitis.
Why is this happening? Is there a possibility of a serious illness?

Xiao Xi: Hello, I think that being young, one is unlikely to have cancer.
Additionally, prior to a urine test, excessive exercise or holding in urine can cause blood to appear in the urine.
Therefore, for the next urine test, please avoid holding in urine and refrain from vigorous exercise for 72 hours before the test.
This will yield more accurate results.
I hope this information is helpful to you.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
Online responses should only be used as a reference; if necessary, it is still important to seek medical attention at a healthcare facility.
The Ministry of Health and Welfare Taitung Hospital cares about you.

Understanding urinalysis results can be a complex process, especially when multiple factors are involved. In your case, the presence of 28 red blood cells (RBCs) and proteinuria (with a reading of ++) raises some concerns, but it is essential to interpret these results in the context of your overall health and any other symptoms you may be experiencing.

Firstly, the presence of red blood cells in urine, known as hematuria, can be indicative of several conditions. These may range from benign causes, such as exercise-induced hematuria or minor trauma, to more serious conditions like urinary tract infections (UTIs), kidney stones, or even tumors in the urinary tract. The fact that you have previously experienced intermittent proteinuria suggests that there may be an underlying issue with your kidneys or urinary system that requires monitoring.

The proteinuria you mentioned (++) indicates that there is an elevated level of protein in your urine. This can be a sign of kidney damage or disease, as healthy kidneys typically do not allow significant amounts of protein to pass into the urine. Common causes of proteinuria include glomerulonephritis, diabetic nephropathy, or hypertension-related kidney damage. Given that your protein levels decreased to +/- in the follow-up test, this could suggest a transient issue, but it still warrants ongoing monitoring.

Your visit to the nephrology department was a prudent step, especially with the new finding of hematuria. The nephrologist's assessment that it does not appear to be kidney inflammation is reassuring, but it is crucial to continue monitoring your urine for any changes. The normal white blood cell count is also a positive sign, as it suggests that there may not be an active infection at this time.

Regarding your concerns about bladder cancer, while it is true that painless hematuria can be a symptom of bladder cancer, it is relatively rare, especially in younger individuals. The likelihood of bladder cancer increases with age and is more common in individuals with risk factors such as smoking or exposure to certain chemicals. Given your age and the absence of other significant risk factors, the chances of bladder cancer being the cause of your symptoms are likely low, but it is essential to follow up with your healthcare provider for further evaluation if symptoms persist or worsen.

The recurrent infections and inflammation you mentioned, such as paronychia (nail fold infection), otitis media (middle ear infection), and orchitis (testicular inflammation), could suggest an underlying issue with your immune system or a tendency towards infections. It may be beneficial to discuss these recurrent issues with your healthcare provider, who may consider further investigations to rule out any systemic conditions that could be contributing to your symptoms.

In summary, while your urinalysis results indicate some abnormalities that warrant further monitoring, the immediate risk of serious conditions like bladder cancer appears low based on your age and health history. It is crucial to maintain regular follow-ups with your healthcare provider, continue monitoring your symptoms, and address any new concerns as they arise. Keeping an open line of communication with your doctor will help ensure that any potential issues are caught early and managed appropriately.
