ABSTRACT

Staghorn stones are urinary stones that have the possibility to disturb the normal kidney physiology, though they do not reduce the renal functions to such a level that will prevent their formation, at least during the course of their progression. During the formation pro-cess, staghorn stones take the shape of renal pelvicaliceal system. Staghorn stones may develop in kidney in pathologic conditions, but it is unusual to find a staghorn shaped sto-ne in the other parts of the urinary system. In literature, a urinary staghorn stone in extra-renal location was reported in a bifid ureter and called as giant ureteral staghorn stone.We report a case of a huge, staghorn like, left ureteral stone measuring 54 x 24 mm, with ab-dominal radiography, intravenous pyelography, retrograd pyelography and ultrasonog-raphy findings.
