Atypical Urine Cytology: Next Steps and Concerns - Urology

Share to:

Initially, there was hematuria, and later the cells showed atypical changes, but it could not be determined precisely..?


In December 2014, I underwent a physical examination that revealed hematuria and slightly elevated blood pressure.
In early February, a follow-up test showed no hematuria, with a creatinine level of 1.1 and a glomerular filtration rate of 86.
The urine cytology indicated atypia of undetermined significance, and the specimen was deemed satisfactory for evaluation.
The doctor recommended follow-up testing in May, which yielded similar results.
Later, in July, I underwent contrast-enhanced imaging of the kidneys and bladder, which showed no abnormalities, and the urine cytology results remained unchanged.

Given that I have had three urine cytology tests since mid-February, all showing the same results, should I consider further evaluation with an MRI or a bladder biopsy? Is there any risk associated with the bladder biopsy, or should I wait for another urine cytology follow-up in three months? Additionally, are there any dietary or lifestyle changes I should actively consider, as I am quite concerned about the possibility of cancer? Thank you!

Young person: Hello, you can first undergo a cystoscopy.
Additionally, is the method of urine sample collection appropriate? Generally, for urine cytology, I personally recommend against using the first morning urine, as it is collected after overnight retention, which may increase the chance of misinterpretation (normal cells may appear abnormal after being immersed in overnight urine).
Note: Some physicians may suggest using the first morning urine, as although the chance of misinterpretation is higher, it can yield a larger number of cells for examination.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
Online responses should only be used as a reference; if necessary, it is still important to seek medical care at a healthcare facility.

Understanding atypical urine cytology can be a source of anxiety for many patients, especially when there is a concern about potential malignancy. In your case, the findings of "atypia of undetermined significance" in your urine cytology indicate that there are abnormal cells present, but these changes are not definitive for cancer. This situation often requires careful monitoring and further evaluation to determine the underlying cause of the atypical cells.

Given your history of hematuria (blood in urine) and the subsequent tests that have shown no significant findings in your kidneys and bladder, it is understandable to feel concerned about the implications of these results. The recommendation from your physician to follow up in May is a standard approach in such cases. Regular monitoring is crucial, as it allows for the detection of any changes over time.


Next Steps and Recommendations
1. Follow-Up Urine Cytology: Continuing with urine cytology every three months is a reasonable approach. This will help to monitor any changes in the atypical cells. If the results remain consistent, your physician may consider extending the interval between tests.

2. Consideration of Cystoscopy: If there are persistent atypical results or if you develop new symptoms (such as increased hematuria or urinary symptoms), a cystoscopy may be warranted. This procedure allows direct visualization of the bladder and can facilitate biopsy if necessary. While cystoscopy is generally safe, it does carry some risks, including infection, bleeding, and discomfort. However, the benefits of obtaining a definitive diagnosis often outweigh these risks, especially if there is a concern for malignancy.

3. MRI or Other Imaging: An MRI is not typically the first-line imaging modality for bladder evaluation; however, if there are specific concerns about the kidneys or surrounding structures, your physician may recommend it. Generally, a CT scan or ultrasound is more commonly used for initial evaluations of the urinary tract.

4. Lifestyle and Dietary Considerations: While there is no specific diet that can prevent bladder cancer, maintaining a healthy lifestyle can be beneficial. Here are some general recommendations:
- Hydration: Drink plenty of water to help dilute your urine and flush out potential irritants.

- Avoid Irritants: Limit consumption of caffeine, alcohol, and spicy foods, as these can irritate the bladder.

- Quit Smoking: If you smoke, quitting can significantly reduce your risk of bladder cancer.

- Healthy Diet: Incorporate a diet rich in fruits and vegetables, which may provide protective benefits against various cancers.

5. Mental Health Support: It’s important to address the anxiety that can accompany health concerns. If you find yourself feeling overwhelmed or experiencing significant distress, consider speaking with a mental health professional. They can provide strategies to cope with anxiety and help you manage your concerns about your health.


Prognosis and Monitoring
The prognosis for atypical urine cytology largely depends on the underlying cause. Many cases of atypical cytology are benign and may resolve over time. However, close monitoring is essential to ensure that any potential malignancy is caught early if it develops.
In summary, continue with your follow-up appointments and urine cytology as recommended by your physician. If you have any new symptoms or concerns, do not hesitate to reach out for further evaluation. Your proactive approach to your health is commendable, and staying informed will empower you to make the best decisions moving forward.
