LEFT KIDNEY
HelloThanks for query. Thinning out of cortex with presence of large stone of a size of 42\u00a0mm is strongly suggestive of a long-standing obstruction to urine flow from kidney in to ureter. This could be due to Pelvis Ureteric Junction Obstruction (PUB Obstruction) resulting into damage to your kidney ... Please consult qualified Urologist for clinical examination and get following basic tests done to confirm the diagnosis.1) Intravenous Paleography or Contrast C. T scan of Kidney ureter and Bladder 2) DMS scan. Further treatment will depend upon result of these tests and final diagnosis. Chat Doctor.
