Hi, I had gone through your question and understand your concerns. Blood in urine is not unusual sig and it may indicate several more or less serious diseases or urinary tract. Most common are benign and include uroinfection, urinary stones or prostate hyperplasia but always should some serious issues be ruled out such as prostate or bladder tumor. If PSA was fine and prostate is fine then you should look for stones as a next step.SO you ll need to do urography and kidneys ultrasound. If stones are ruled out then CT scan of bladder and urotract is required if bleeding persist. Try to drink more fluids and raspberry tea to promote urination till you do these tests. Do write back to me for any further clarifications, I am always available to help. Best wishes.
