[|AI|]  Hello! Thank you for the query. Blood in the urine can be the first symptom of bladder cancer indeed. Especially if no sign of infection. But most probable reason of it are stones. Please note that stones can recur. And even if no evidence of stones in the ultrasound, some small stones can be present. I suggest you to consult urologist in that matter. Cystoscopy to rule out cancer should be done. Hope this will help. Regards.
