"The proximal ureter courses posterior to the IVC, then emerges to the right of the aorta, coming to lie anterior to the right iliac vessels. There is typically right hydroureteronephrosis above the segment related to the IVC. Intravenous urogram classically depicts a fishhook-shaped or S-shaped deformity of the ureter in type 1 or the low loop variety. In type 2, the retrocaval segment is at the same level as the renal pelvis; the sickle-shaped appearance of the involved ureter can be identified on IVU. Type 2 generally causes mild hydronephrosis and is less common than type 1."
