The renal veins empty into the inferior vena cava, entering it at nearly a 90° angle. [1] Due to the right-ward displacement of the inferior vena cava from the midline, the left renal vein is some 3 times longer than the right one (~7.5 cm and ~2.5 cm, respectively). [1]
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 ...

The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins , usually at the level of the fifth lumbar vertebra .
The inferior vena cava and the abdominal aorta sit to the midline of the right and left ureters, respectively. [2] In the lower part of the abdomen, the right ureter sits behind the lower mesentery and the terminal ileum, and the left ureter sits behind the jejunum and the sigmoid colon. [2]

In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg.: vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin 'hollow veins') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium ...
The left gonadal vein usually empties into (inferior aspect of) [2] the ipsilateral renal vein [2] [3]: 1144 proximally to where the renal vein crossing over the aorta. [ 2 ] The right gonadal vein typically empties directly into the (right anterolateral aspect of) inferior vena cava , joining it at an acute angle, some 2 cm inferior to the ...
