Urinary occult blood: The color of the urine gradually changes from brown to lighter shades?

Hello, Doctor.
Last Monday night, shortly after lying down to sleep, I started experiencing abdominal pain, which then radiated to my back.
This condition persisted until the following morning.
After that, the color of my urine began to appear tea-colored, and the darker tea color had sediment, lasting for about four to five days.
Recently, the color of my urine has gradually lightened, and now only the first urine in the morning is somewhat yellow.
I visited the urology department at the hospital, where I underwent urinalysis, X-rays, and an ultrasound.
The X-rays and ultrasound showed that both my kidneys and bladder were normal, with no stones present, but my urine tested positive for hematuria.
(Before going to the large hospital for emergency care, I had done a urinalysis elsewhere, which showed no hematuria.) The doctor has arranged for imaging tests (with contrast injection) and a urine cytology.
What are these two tests checking for? Why were the results for hematuria different between the two urinalyses? Could the symptoms I described indicate that a stone has already passed but caused some abrasion in the urethra during the process, resulting in the hematuria? P.S.
Aside from the pain that night, I have not experienced any further pain, although sometimes I feel a dull ache in my lower back and above my buttocks.
I apologize for the lengthy explanation, and thank you, Doctor!

Hello: I am not your physician, but I can offer some suggestions.
You still need to follow up with your doctor.
Hematuria may not always be detected during every test, so it may be necessary to repeat the tests after some time.
X-rays, ultrasounds, imaging studies, and urine cytology are all used to rule out common issues such as stones or urinary tract tumors.
Your suspicion of small stones is possible (as small stones often pass on their own and can also be associated with hematuria).
Currently, what you can do is to drink plenty of water, engage in moderate exercise, and return for follow-up as advised by your physician.
Additionally, I would like to remind you that plain water is preferable, and it's best to limit the consumption of various beverages, as they can contribute to stone formation over time.
I hope you stay safe and calm.
Thank you for your inquiry.
For someone who is 60 years old, it is recommended to have an annual health check-up.

More Info

Tea-colored urine can be a concerning symptom, and understanding its potential causes is crucial for determining whether further medical evaluation is necessary. Based on your description, it appears that you experienced abdominal pain that radiated to your back, followed by the appearance of tea-colored urine with sediment. This symptom persisted for several days before gradually lightening. You also mentioned that you underwent various diagnostic tests, including urinalysis, X-ray, and ultrasound, which showed no kidney stones but indicated the presence of hematuria (blood in urine).

Understanding Tea-Colored Urine
Tea-colored urine can result from several factors, including:
1. Dehydration: Concentrated urine can appear darker, resembling tea. However, your symptoms suggest a more complex issue.

2. Dietary Factors: Certain foods, such as beets or blackberries, can alter urine color. However, this seems less likely given your symptoms.

3. Medications: Some medications can change urine color. If you are taking any medications, it’s worth considering this possibility.

4. Medical Conditions: Conditions such as hematuria, liver disease, or hemolysis (destruction of red blood cells) can cause tea-colored urine. Given your history of abdominal pain and the presence of blood in your urine, it is essential to investigate further.

Diagnostic Tests Explained
You mentioned that your doctor ordered additional tests, including imaging with contrast and urine cytology. Here’s what these tests typically evaluate:
- Imaging with Contrast: This test, often referred to as a CT scan with contrast, helps visualize the urinary tract, including the kidneys, ureters, and bladder. It can identify abnormalities such as tumors, strictures, or other structural issues that might not be visible on standard X-rays or ultrasounds. The contrast agent enhances the images, allowing for a clearer view of the urinary system.

- Urine Cytology: This test examines urine samples under a microscope to check for abnormal cells. It is particularly useful in detecting bladder cancer or other malignancies in the urinary tract. If there is a concern about potential tumors or other cellular abnormalities, this test can provide valuable information.

Variability in Urine Test Results
The discrepancy in urine test results regarding the presence of blood can occur for several reasons:
- Sample Variability: Different samples can yield different results due to variations in hydration status, recent physical activity, or even the timing of the sample collection.

- Transient Hematuria: Sometimes, blood in the urine can be transient, meaning it may not be present in every sample. This can occur due to minor injuries, such as those from passing a small stone or irritation from a urinary tract infection.

- Laboratory Error: Although rare, discrepancies can occur due to errors in processing or analyzing urine samples.

Potential Causes of Your Symptoms
Given your symptoms of abdominal pain, tea-colored urine, and the presence of hematuria, several conditions could be considered:
- Urinary Tract Infection (UTI): While you may not have experienced typical UTI symptoms, some infections can present with hematuria and abdominal discomfort.

- Kidney Stones: Even if imaging shows no stones, it is possible that a small stone could have passed, causing irritation and bleeding.

- Glomerular Disease: Conditions affecting the kidneys' filtering units can lead to hematuria and changes in urine color.

- Liver Issues: Since tea-colored urine can also indicate liver problems, it may be worth discussing liver function tests with your doctor.

Conclusion
In summary, tea-colored urine accompanied by abdominal pain and hematuria warrants thorough investigation. The tests your doctor ordered are essential for identifying any underlying issues. It is crucial to follow up with your healthcare provider regarding the results of these tests and any further steps needed for diagnosis and treatment. If you experience any new or worsening symptoms, such as increased pain or changes in urination, seek medical attention promptly.
