Urinary Tract Infections: When to Seek Further Testing - Urology

Could you please provide more details about urethritis?


Hello Dr.
Hsu: I only urinated once in a day, and after drinking a lot of water, I couldn't urinate again.
I went to the pharmacy, and they gave me a 7-day course of antibiotics, which I have been taking for 3 days.
My condition has improved; there is no discharge, and I no longer feel pain.
However, sometimes I feel feverish, and my lower back is sore.
I'm still a bit worried, but I have already taken the antibiotics.
Should I wait until I finish the medication and then get a urine test after 7 days to check for any other conditions? Thank you again.

Dr. Xu Weikai reply Urology


Tony: For general urethritis, it is recommended to repeat a urine test three days after stopping medication to confirm that there are no issues, which should indicate that the condition has resolved.
This is a response from Dr.
Hsu Wei-Kai, Chief of Urology, to the Taitung Hospital of the Ministry of Health and Welfare, expressing concern for your well-being.

More Info


Urinary tract infections (UTIs) are a common health issue, particularly among women, due to anatomical and physiological factors. Your symptoms, including discomfort during urination, potential fever, and lower back pain, suggest that you may be experiencing a UTI or possibly a more complicated infection, such as a kidney infection (pyelonephritis).
When you initially sought treatment and were prescribed antibiotics, it was a step in the right direction. Antibiotics are typically effective in treating UTIs, and many patients start to feel better within a few days. However, it is crucial to complete the entire course of antibiotics as prescribed, even if symptoms improve, to ensure that the infection is fully eradicated and to prevent the development of antibiotic resistance.

Given that you are still experiencing symptoms such as a fever and lower back pain, it is essential to monitor your condition closely. A fever can indicate that the infection may not be fully resolved or that it has progressed to a more serious condition. Lower back pain, particularly if it is unilateral (on one side), can be a sign of kidney involvement, which requires prompt medical attention.

In terms of further testing, it is generally advisable to follow up with your healthcare provider if symptoms persist or worsen after completing the antibiotic course. You may need a repeat urine test to check for the presence of bacteria or other abnormalities. Additionally, if you have a fever or significant pain, your doctor may recommend imaging studies, such as an ultrasound or CT scan, to evaluate your kidneys and urinary tract for any complications.

Regarding your question about waiting seven days after finishing the antibiotics to test again, it is not uncommon for healthcare providers to recommend a follow-up urine test after treatment to confirm that the infection has cleared. However, if you are experiencing concerning symptoms like fever or significant discomfort, it is better to seek medical advice sooner rather than later. Your healthcare provider can assess your situation and determine if additional tests or a different treatment approach is necessary.

In summary, while antibiotics are effective for treating UTIs, persistent symptoms warrant further evaluation. It is crucial to communicate openly with your healthcare provider about your symptoms and any concerns you have. They can provide tailored advice and ensure that you receive the appropriate care to address your urinary health effectively. Remember to stay hydrated, practice good hygiene, and follow up with your doctor as needed to prevent recurrent infections.
