Hi and thanks for the query, blood in the urine in the absence of lower urinary tract symptoms like pain on urination, frequent urination or difficulties in holding urine often lead first to the suspicion of a bladder tumour. A urine cytology and urological examination and advice is usually needed in this situation. However, possibilities of urinary tract infections must always be ruled out by carrying out routine urine cultures and anti biotic sensitivity test. Exposures to paints in the past is a important risk factor to be considered. A past history of having spent time in a water logged zone, which could be endemic to Schistosomiasis (S. Histolytica) could a possibility to bear in mind too. Consulting with a urologist could be very necessary. Thanks and best regards, Luchuo, MD.
