Urinary tract infection and subsequent lower back pain follow-up?


Hello, I have already gone to a large hospital for examination due to concerns about bacteremia.
After blood tests, urinalysis, X-rays, and kidney ultrasounds, the doctor said there were no significant issues.
However, I still occasionally feel some discomfort near the urethral opening.
The last urinalysis at the clinic indicated that there are still some bacteria remaining.
Could it be that I might need more time to fully recover?

Hello, if these tests have been done, it will take some time to improve.
It is recommended to drink plenty of water and get more rest.
However, if you suddenly experience a fever or increased pain later on, you will need to return to a major hospital for a detailed examination.
Thank you for your inquiry.

More Info


Urinary tract infections (UTIs) can be a persistent and uncomfortable issue, especially when symptoms linger despite medical intervention. Based on your description, it seems that you have undergone a thorough evaluation, including blood tests, urinalysis, X-rays, and kidney ultrasounds, which have not indicated any serious underlying conditions. However, the presence of residual bacteria in your urine suggests that the infection may not have been fully resolved, which could explain the ongoing discomfort near the urethra.

UTIs are typically caused by bacteria entering the urinary tract, and they can lead to symptoms such as painful urination, frequent urges to urinate, and discomfort in the lower abdomen or back. In some cases, even after treatment with antibiotics, patients may continue to experience symptoms due to several reasons:
1. Incomplete Treatment: Sometimes, the prescribed antibiotic may not be effective against the specific strain of bacteria causing the infection. This can lead to a situation where the symptoms improve temporarily but do not fully resolve.

2. Recurrent Infections: Some individuals are prone to recurrent UTIs, which can occur due to anatomical factors, hormonal changes, or lifestyle habits. If you have a history of UTIs, it may be worth discussing preventive measures with your healthcare provider.

3. Underlying Conditions: Although your recent tests did not reveal any significant issues, conditions such as interstitial cystitis or bladder inflammation can mimic UTI symptoms. These conditions may require different treatment approaches.

4. Residual Bacteria: As noted in your urinalysis, the presence of residual bacteria could indicate that the infection is still present or that there is a biofilm formation, where bacteria adhere to the urinary tract lining, making them more resistant to antibiotics.

Given your situation, it is advisable to follow up with your healthcare provider. They may recommend a repeat urinalysis to check for the presence of bacteria and possibly adjust your treatment plan based on the results. Additionally, they might consider a longer course of antibiotics or a different class of antibiotics if the current treatment has not been effective.

In the meantime, there are several self-care measures you can adopt to help alleviate symptoms and support your urinary tract health:
- Stay Hydrated: Drinking plenty of water can help flush out bacteria from your urinary tract. Aim for at least 8-10 glasses of water daily.

- Avoid Irritants: Certain foods and beverages, such as caffeine, alcohol, spicy foods, and artificial sweeteners, can irritate the bladder. Reducing or eliminating these from your diet may help.

- Practice Good Hygiene: Ensure proper hygiene, especially after using the bathroom and during sexual activity, to minimize the risk of introducing bacteria into the urinary tract.

- Consider Probiotics: Some studies suggest that probiotics may help restore the natural flora of the urinary tract and may reduce the risk of recurrent infections.

- Monitor Symptoms: Keep track of your symptoms, noting any changes or patterns, which can provide valuable information for your healthcare provider.

In conclusion, while it can be frustrating to deal with persistent symptoms after a UTI, it is essential to maintain open communication with your healthcare provider. They can guide you through the next steps and help ensure that you receive the appropriate treatment to resolve your symptoms effectively.
