In the initial workup for suspected urinary tract malignancy presenting with asymptomatic microscopic hematuria, which combination of tests is recommended?

• A. Urinalysis alone
• B. Abdominal ultrasound
• C. MRI pelvis
• D. Renal function testing, CT urography, and cystoscopy

Answer: (D)

When assessing suspected urothelial cancer in someone with asymptomatic microscopic hematuria, the goal is to evaluate both the upper urinary tract and the bladder while ensuring imaging is done safely. Renal function testing establishes baseline kidney function and determines whether iodinated contrast can be used for CT urography, which is important for avoiding contrast-related kidney injury. CT urography then provides a comprehensive view of the kidneys, ureters, and bladder, detecting upper-tract lesions as well as bladder abnormalities with high sensitivity. Cystoscopy adds direct visualization of the bladder lining and the opportunity to biopsy any suspicious lesions, which is crucial because bladder tumors can be occult on imaging alone. Together, these tests cover the full scope of the workup needed to identify potential malignancy and guide subsequent management. Urinalysis by itself can miss issues, ultrasound alone is less sensitive for upper-tract tumors, and MRI pelvis is not the standard initial approach for this scenario, making the combination of renal function testing, CT urography, and cystoscopy the best-fit initial workup.
