White Particles in Urine: Causes and Concerns in Urology - Urology

White object


Hello, I experienced a urinary tract infection around November 2022, which led to a fever and a visit to the emergency room.
Blood and urine tests revealed that Escherichia coli had entered my bloodstream, causing the fever.
After recovering, I had a recurrence in December, but without fever.
I obtained medication from a nearby clinic and recovered after finishing the course.
Shortly after, within 1-2 days, I developed a Candida infection, which I have been treating since late December.
During this period, I have used oral medications and topical ointments, and I also used suppositories during the Lunar New Year.
After the holiday, my condition has not improved, so the doctor prescribed more oral medications and ointments, and I am still undergoing treatment.
However, after the New Year, I occasionally notice white, granular, flaky, or irregular-shaped objects in my urine.
I would like to ask you: 1.
Is it possible that these are remnants from the suppositories used during the Lunar New Year? 2.
Could it be that my urinary tract infection has not fully resolved? Previously, the doctor mentioned that black spots in the urine indicated inflammation or bleeding in the bladder or urethra, but now I am seeing white.
Is it possible that there are other issues with my bladder or kidneys, or is this normal and not a cause for concern? Thank you.

If symptoms persist, you can visit the outpatient clinic for a urinalysis and bacterial culture.
An ultrasound examination can also be performed to rule out other issues.

The presence of white particles in urine, especially following a history of urinary tract infections (UTIs) and yeast infections, can be concerning and warrants a thorough understanding of potential causes and implications. Given your medical history, it is essential to consider several factors that could contribute to the symptoms you are experiencing.

1. Possible Residue from Medications: It is plausible that the white particles you are observing could be remnants of medications, particularly if you have been using topical treatments or suppositories. Some medications can crystallize or form precipitates in urine, especially if they are not fully absorbed by the body. If you used a suppository during the holiday period, it is worth discussing with your healthcare provider whether this could be a contributing factor.

2. Persistent Infection: Your history of recurrent UTIs, particularly caused by E. coli, raises the possibility that your urinary tract may still be harboring an infection. While you mentioned that you have been treated for yeast infections, it is important to note that a UTI can sometimes coexist with other infections. The presence of white particles could indicate the presence of pus (white blood cells) or other inflammatory materials, suggesting that your urinary tract may still be inflamed or infected.
3. Inflammation or Damage: The white particles could also be indicative of inflammation in the urinary tract, possibly from the bladder or kidneys. If there is ongoing irritation or damage to the lining of these structures, it could lead to the shedding of cells or other materials that appear as white particles in urine. Your previous observation of black dots in urine could have been related to blood or debris from inflammation, and the transition to white particles may suggest a change in the nature of the irritation or infection.

4. Normal Variations: While it is essential to consider the above possibilities, it is also important to recognize that urine can contain various substances that may not necessarily indicate a serious problem. For instance, certain dietary factors, hydration levels, and even the presence of mucus can contribute to changes in urine appearance. However, given your symptoms and medical history, it is prudent to approach this with caution.

5. Recommended Actions: Given your ongoing symptoms and concerns, it is advisable to seek further evaluation from a urologist or your primary care physician. They may recommend a urinalysis to check for the presence of white blood cells, bacteria, or other abnormalities. A urine culture could also help identify any lingering infections. Additionally, imaging studies such as an ultrasound may be warranted to assess the kidneys and bladder for any structural issues.

In conclusion, while the presence of white particles in urine can sometimes be benign, your medical history and the persistence of symptoms suggest that further investigation is warranted. It is crucial to communicate openly with your healthcare provider about your concerns and to follow up with appropriate diagnostic tests to ensure that any underlying issues are addressed promptly. Your health and well-being are paramount, and taking proactive steps can help you achieve a better understanding of your condition and the necessary treatment options.
