OK, first off stones start off in the kidneys, most are formed from oxalate, not from a urinary infection. Now, kidney
stones can make you feel like you have in infection

in the area (ureter) they are, if they are in the ureter, that is one of two tubes that come from the kidneys, one tube for each kidney about 6m or so in diameter, in females they are about 50-70mm long each one empties urine in the bladder and then pass through the larger diameter urethra.
