I am a 62 year old male, i have had an ongoing UTI with a brief period of gross hematuria. A recent MRI shows an abnormal enhancement of the right collecting system especially involving the upper and lower pole calyces.in addition there is an abnormal thickening of the right renal pelvis and proximal ureter. The suspicion is for either infiltrating transitional carcinoma or an inflammatory etiology. Other than frequent urination, no pain, no fever, no weight loss, just stress while i am waiting to clear the e-coli infection so that internal testing can proceed and diagnose the problem. I have a history of frequent stones and presently have 2 in my right kidney What is the likelyhood of a positive outcome
