Preureteric vena cava or retrocaval ureter is an uncommon congenital anomaly where the right ureter runs behind and medial to the inferior vena cava (IVC) due to dysgenesis of the IVC. This abnormality has been diagnosed using computed tomography urography (CTU), nuclear scintigraphy, ultrasound, intravenous urography, and magnetic resonance urography (MRU). When the illness manifests symptoms, surgery, either open or laparoscopic, is used to treat it.[1]
