Click 76 year old male with an inguinal hernia of the ureter, presenting with acute renal failure. Axial image of CT a urogram with the patient in a prone position shows a contrast-filled right ureter within the right inguinal canal. Bilateral inguinal hernia sacs are present, and the herniated ureter is seen medial to the right inguinal hernia sac. Note is also made of placement of a percutaneous drain into a left renal abscess. Bilateral hip prostheses are present. This study was performed using GE LightSpeed 16-slice CT scanner using kV 140 and mA 379. 40 cc in intravenous Visipaque was injected at time 0. At 5 minutes an additional 120 cc of Visipaque was injected. At 7 minutes a combined nephrographic/execretory phase helical CT was performed of the abdomen and pelvis using 0.625 mm collimation with 2.5 mm axial reconstructions and 3 mm bilateral oblique reconstructions.
