A 16-year-old boy was hemodynamically stable after sustaining a gunshot wound to his abdomen. Physical examination revealed left suprapubic entry and gluteal exit wounds. At laparotomy, the left external iliac vein was repaired and a diverting colostomy was performed because of extensive sigmoid injury. There were no signs of ureteral injury. Postoperatively, the patient developed fevers and mild azotemia. Contrast-enhanced computed tomography (CT) (Fig 1A) showed copious ascites that enhanced on delayed images (Fig 1B). A CT cystogram was normal. CT urography (Fig 1C) demonstrated left ureteral laceration. A retrograde double J-stent was placed cystoscopically before definitive repair.
