Some patients, especially with chronic disease such as diabetes, who suffer from lower urinary tract symptoms (LUTS) just want to take prolonged oral medication (anticholinergics or alpha blockers) without proper evaluation for basic causes. LUTS is commonly occurred by urinary tract infection, several chronic diseases and/or aging itself. However, we should not pass over the fact that LUTS also can be evoked by malignancy. Because there is a higher detection rate of malignancy in patients with microscopic hematuria, urine cytology must be done with ultrasonography, IVP and cystoscopy. In those patients aged over 50 years or high risk group for urothelial carcinoma, it is mandatory to undergo ultrasonography and cystoscopy, even if there is no abnormalities on their urinalysis and urine cytology.
