Retroiliac Ureter or Preureteral Iliac Artery
A retroiliac ureter is very rare and associated malformations are common. The retroiliac ureter is caused by the development of the iliac vessels from the anterior branch of the umbilical artery (instead of the normally dorsal branch). The ureter can be compressed by iliac vessels causing hydronephrosis.
