Urinary issues


Hello, doctor.
I would like to ask, after urinating, I noticed many particles in the toilet when looking at it from the side due to the reflection, but I can't see them when looking straight down.
Could this be a symptom of inflammation or kidney stones? Thank you.

Zhang, 30~39 year old female. Ask Date: 2019/03/08

Dr. Cai Zhuorong reply Urology


It is recommended to perform a urinalysis.

When you notice particles in your urine, it can be concerning and may lead you to wonder whether these are signs of a urinary tract infection (UTI) or kidney stones. Understanding the nature of these particles is crucial for determining the underlying cause and appropriate treatment.

Firstly, the presence of particles in urine can be attributed to various factors. If the particles are small, they could potentially be crystals, which are often associated with kidney stones. Kidney stones can form from various substances, including calcium, oxalate, uric acid, and cystine. The formation of these stones can lead to symptoms such as hematuria (blood in urine), pain during urination, and sometimes even obstruction of the urinary tract, which can cause hydronephrosis (swelling of the kidney due to urine buildup).

On the other hand, if the particles are more like pus or mucus, this could indicate a urinary tract infection. UTIs are commonly caused by bacteria entering the urinary tract, leading to inflammation and the presence of white blood cells (pus cells) in the urine. Symptoms of a UTI can include a burning sensation during urination, frequent urge to urinate, and cloudy or foul-smelling urine. In some cases, individuals may not experience noticeable symptoms, especially in mild infections.

In your case, since you mentioned seeing particles after urination, it would be beneficial to consider the following:
1. Color and Clarity of Urine: If your urine appears cloudy or has a strong odor, this could suggest a UTI. Clear urine with small particles might lean more towards the presence of crystals or sediment.

2. Associated Symptoms: Are you experiencing any pain during urination, frequent urination, or any abdominal discomfort? These symptoms can help differentiate between a UTI and kidney stones.

3. Urinalysis: A urinalysis can provide valuable information. It can help identify the presence of bacteria, white blood cells, red blood cells, and crystals. If your doctor suspects a UTI, they may also perform a urine culture to identify the specific bacteria causing the infection.

4. Imaging Studies: If kidney stones are suspected, imaging studies such as an ultrasound or CT scan may be necessary to visualize the stones and assess their size and location.

5. Hydration and Diet: Staying well-hydrated is crucial in preventing both UTIs and kidney stones. Drinking plenty of water helps dilute the urine and flush out potential irritants. Additionally, dietary modifications may be necessary if you are prone to specific types of stones.

In conclusion, the particles you observed in your urine could indicate either a urinary tract infection or the presence of kidney stones. It is essential to consult with your healthcare provider for a thorough evaluation, which may include a urinalysis and possibly imaging studies. They can provide a definitive diagnosis and recommend appropriate treatment based on the underlying cause. If you have any additional symptoms or concerns, do not hesitate to seek medical attention promptly.
