Welcome. None of us are doctors so our ideas are worth.... about 2 cents, as the joke goes. Personally, I'd get a second opinion. Your post does indicate via pathology some kind of growth. Also, you still need to find out why you have microscopic hematuria. Many times it is never even found out why but, any bleeding should still be chceked out. Often, a CT scan of the torso is done to rule out other urinary tract problems. So, yes, get a second.
