Q. A 65 y/o man with history of chronic smoking and COPD presents for follow up visit in your office after being discharged from the hospital about three weeks ago.
The patient was admitted and treated in the hospital for community acquired pneumonia and COPD exacerbation. During his hospital stay he was noted to have microscopic hematuria on routine urinalysis. The patient denies any symptoms now. His COPD is well controlled on tiotropium inhaler. His allergies include Isoniazid and Penicillin. Past medical history is significant for a positive PPD test ( latent tuberculosis) for which he has been on treatment with Rifampin for past three months. Physical examination is benign. Labarotory investigations reveal a normal CBC and serum creatinine. Dipstick is positive for blood. A repeat urinalysis during this visit reveals persistent microscopic hematuria with 3 RBCs/HPF. A urine cytology has been sent. The next appropriate step in evaluating this patient’s hematuria is:
A) Repeat urinalysis in 3 months
B) Urine cultures
C) Intravenos pyelogram
D) CT urogram and Cystoscopy
E) Stop Rifampin
