Urinalysis


Hello Dr.
Zhang: I have been experiencing lower back pain and occasional frequent urination, although the urine volume is not much.
I usually drink more than 1500 ml of water a day.
During my first visit to the doctor, a urine test was conducted, and everything was normal.
I was prescribed medication for three days and asked to return for a follow-up.
During the second visit, another urine test revealed the presence of bacteria, and an X-ray was performed.
The doctor mentioned that I have nephroptosis, which makes me prone to inflammation and infection.
I was prescribed a three-day course of antibiotics (Bistor 100 mg/cap) and asked to return for another urine test.
However, the doctor indicated that the bacterial count was still high (two plus signs), and interestingly, the white blood cell count was normal.
The doctor mentioned that typically, a three-day course of antibiotics should suffice.
He suggested further evaluation with an ultrasound to check for possible inflammation in the digestive or reproductive systems that could be causing the urinary infection.
He advised me to continue taking antibiotics for another three days and then undergo the ultrasound.
Is this a serious issue? The way he described it sounded quite severe, and I am a bit worried (I usually drink plenty of water and do not hold my urine, averaging a bathroom visit every two hours).
Thank you for your response, doctor.

Hello: If the urine test is normal, antibiotics should not be taken orally, as there may be a possibility of free kidney stones.
Please consult your attending physician.
Thank you!

Understanding urinary tract infections (UTIs) is crucial, especially for those experiencing recurrent symptoms. UTIs can manifest in various ways, and the symptoms can range from mild discomfort to severe pain. Common symptoms include a burning sensation during urination, frequent urges to urinate, cloudy or strong-smelling urine, and lower abdominal pain. In some cases, individuals may also experience back pain, which can indicate a more serious infection involving the kidneys.

In your case, it appears that you have been experiencing a combination of symptoms, including lower back pain and frequent urination with low urine output. The fact that you have undergone multiple urine tests, and the results have shown the presence of bacteria but normal white blood cell counts, is intriguing. Typically, a UTI is characterized by elevated white blood cells in the urine, indicating an immune response to infection. However, there are instances where bacteria can be present without a corresponding increase in white blood cells, particularly if the infection is chronic or if the body is not mounting a significant immune response.

The treatment regimen you are currently on, which includes antibiotics, is standard for UTIs. However, the persistence of bacteria despite antibiotic treatment raises concerns. It is essential to consider factors such as the possibility of antibiotic resistance, the presence of underlying anatomical abnormalities (like the kidney descent you mentioned), or even issues related to the bladder or urethra that could predispose you to recurrent infections.

Your doctor’s recommendation for an ultrasound is prudent. This imaging study can help identify any structural abnormalities in the urinary tract or surrounding organs that may be contributing to your symptoms. Conditions such as kidney stones, tumors, or anatomical variations can lead to recurrent UTIs and should be evaluated.

Regarding your concern about the severity of your condition, it is understandable to feel anxious when faced with ongoing symptoms and the prospect of further testing. However, many urinary tract issues can be effectively managed once the underlying cause is identified. The key is to maintain open communication with your healthcare provider and to follow through with the recommended tests and treatments.

In addition to antibiotics, there are supportive measures you can take to help alleviate symptoms and reduce the risk of future infections. These include:
1. Hydration: Continue to drink plenty of fluids, particularly water, to help flush out bacteria from your urinary tract.


2. Hygiene: Maintain good personal hygiene, especially after using the bathroom and during sexual activity, to minimize the risk of introducing bacteria into the urinary tract.

3. Cranberry Products: Some studies suggest that cranberry juice or supplements may help prevent UTIs, although they should not replace medical treatment.

4. Probiotics: These may help restore the natural flora of the urinary tract and could be beneficial, especially if you have taken multiple courses of antibiotics.

5. Follow-Up: Regular follow-up appointments with your healthcare provider are essential to monitor your condition and adjust treatment as necessary.

In summary, while your symptoms and the presence of bacteria in your urine are concerning, there are many avenues for diagnosis and treatment. The ultrasound will provide valuable information, and with the right approach, many individuals can find relief from recurrent UTIs. Always consult your healthcare provider for personalized advice and treatment options tailored to your specific situation.
