What is the role of urinary cytology in the diagnosis of BK virus?

• A. To identify infections
• B. To monitor renal function
• C. To detect cancer
• D. To assess treatment response

Answer: (A)

The role of urinary cytology in the diagnosis of BK virus primarily revolves around identifying infections. BK virus, a member of the Polyomavirus family, is known to cause significant issues, particularly in immunocompromised patients, including renal transplant recipients. In these patients, urinary cytology can reveal characteristic changes in the urine that indicate the presence of viral infections. Urinary cytology involves examining cells from the urine under a microscope, allowing for the detection of viral cytopathic effects such as enlarged cells or other abnormal cellular changes associated with BK virus infection. This method serves as a crucial diagnostic tool to help confirm the suspicion of BK virus, especially in the context of kidney transplantation where early intervention can be vital to preserving kidney function. While monitoring renal function, detecting cancer, and assessing treatment response are important aspects of patient management in renal transplant recipients, these roles do not directly correlate with the primary function of urinary cytology in the context of BK virus infections. Monitoring renal function typically involves serological assessments and imaging studies, cancer detection would require specific diagnostic tests beyond cytology, and treatment response assessments can be done with virological testing or renal biopsy rather than purely cytological examination.
