It's transitional cell carcinoma, which smoking is a common risk factor for; it can involve the renal pelvis/calyces. The histo image shows the papillary nature of the tumor (however it can also be flat or nodular according to Pathoma).

Also known as urothelial carcinoma. Most common tumor of urinary tract system (can occur in renal calyces, renal pelvis, ureters, and bladder). Can be suggested by painless hematuria (no casts).

Is this the one with the poor kidney that was cut in half against its will and has a dilated distal ureter? If so, probably showing us transitional carcinoma with mild invasion into that distal ureter. Pathoma does a pretty awesome job of talking about GU cancers (and most cancers) ((and most medicine)) IMO.
