I would assume it mean absent of the left renal function or kidney
It is the failure of the fetal kidneys to form
An agenesis is an imperfect development of the body, or an anomaly of organization.
I believe it is called Unilateral Renal Agenesis.
Renal veins empty into the inferior vena cava
mild fullness of left renal collecting system
Aplasia is the absence of the organ with only the rudiment present Agenesis is the complete lack of the organ
The left and right renal arteries and veins branch off from the abdominal aorta.
agenesis
left atrium -> left ventricle -> aorta -> renal artery -> renal vein -> inferior vena cava -> right atrium -> right ventricle
left
uterine agenesis
Since the renal veins empty into the large inferior vena cava, it is more reasonable for the smaller amount of venous blood flow from the testicle to use the renal vein (rather than empty directly into the inferior vena cava).
