- Repeated urinary tract infection with organisms that produce urease produces the staghorn calculi leads to a large formation and growth of the struvite stone in the ureter. This stone is so big that it forms and fills the entire proximal urinary tract, including the branching calyces. This is why the stone appears like horns of a stag.
