Ileal ureter interpositions are uncommon urologic reconstructions, using a loop of small bowel to replace a damaged ureter. The concept is similar to the formation of a neobladder from small bowel (e.g. ileal conduit), except one is forming a neo-ureter.
Variants include using colon as an interposition or creating a Roux-en-Y conduit 3-4.
