case_images: A CT of the abdomen and pelvis was obtained in the emergency room, which revealed moderate right hydronephrosis secondary to an eroded IVC filter limb projecting in the right proximal ureteral lumen (Figs. 1 and 2).
case_images: Coronal cut CT with additional demonstration of filter limb penetrating right ureter.

case_images: A CT of the abdomen and pelvis was obtained in the emergency room, which revealed moderate right hydronephrosis secondary to an eroded IVC filter limb projecting in the right proximal ureteral lumen (Figs. 1 and 2).
case_images: Antegrade nephrostogram immediately after filter retrieval showing luminal narrowing at site of limb penetration, without evidence of extravasation.
