Bullet colic

Ureteral obstruction by intramural bullet, buckshot, or related missle following penetrating abdominal trauma is rare; a search of the literature revealed only 4 previously described cases [1-4]. A fifth case of a bullet migrating from the renal pelvis to the ureter has been reported at autopsy [5]. We present 2 new cases of delayed symptomatic ureteral obstruction ("bullet colic") after abdominal gunshot wounds.
