      ABSTRACT

      Jackstone calculus is a rare bladder stone with a unique appearance, presenting a stippled and spiculated contour. Correct diagnosis is important because it may have therapeutic implications, as this distinctive shape correlates with a specific mineral composition of calcium oxalate dihydrate, which tend to be easily fragmented by lithotripsy, allowing to attempt an endoscopic treatment instead of surgery in larger stones.
      We present the case of a 77-year-old male where a 2 cm bladder calculus was incidentally found on CT, with features that allowed to make straightforward the diagnosis of a jackstone calculus.
