I'd have to look up what she called it. Urologist knows I don't like CTs, so recommended an MRI, to have before I see her, and found out I'd have to lay on back for 90 min! So told them I don't want that either, since have back problems. She was going to follow up with it. See her after nephrologist appt. (I am on cancellation list) I had an ultrasound of it earlier this month, and she saw where it hasn't grown that much. That wasn't bad, except for holding 32 oz water in my bladder for an hour before. I'll have to ask about a sonogram. Is that radiation free? I don't want surgery as I have copd, level 3, and one surgeon said might not make it through surgery well.
