A 2-year-old male neutered persian cross was presented with lethargy. Blood tests showed creatinine greater than 9.2mg/dL and phosphorus >20mg/dL. On US examination, neproliths were found in both kidneys. To me therse nephroliths are not causing obstruction of the renal pelvis and the renal pelvis is not dilated. I do get sometimes confused as to how to differentiate between renal medulla and the renal pelvis when it is dilated – any tips. There is increased cortex to medulla ration in both kidneys – any siginificancae of this – does it indicate AKI? Both kidneys have a cyst also
