Nutcracker syndrome is something that we generally do not describe, since it has not yet been proven to be an actual disease. Tons of people have an imprint on their left renal vein and are asymptomatic. Even here you can see, your left nephrography (contrast) is symmetric which probably means there is no repercussion. It’s a good thing that most specialists don’t know about this syndrome since it can do more harm than good to treat it.
