Coping With Hematuria

I’ve had periods of hematuria since October 2009. When I’m on my feet for for awhile I get abdominal pain and then can see the hematuria when I urinate. Ultra sound was clear. CAT scan showed 2 bilateral kidney stones 1mm each (which my urologist said is not causing the blood). A bladder scope showed a pappilary tumor which was removed on 12/31/09. I am still having pain and hematuria (more often with menstration). They gyno said one has nothing to do with the other and instructed I go back to the urologist. I went back to the urologist and he told me its probably due to the surgery (3 weeks ago) and told me to come back again in a month. At this point I am very frustrated. I teach sports for a living and standing on my feet for 45 minutes creates abdominal pain and hematuria I am angry with my doctors for passing me off and not coming up with a solution. I am a healthy, in shape 28 year old female and should be able to teach a pee wee soccer class for 45 minutes without being in pain and seeing blood in my urine. Any advice or people with similar stories would be very helpful!
