Has anyone explored nutcracker syndrome?

Like the title says, there’s a decent amount of literature on nutcracker syndrome on some crossover symptoms like back/flank pain, bladder issues and more. Venous congestion. What a crazy concept right? Anyway. Has anyone here, mods or otherwise, done research into nutcracker syndrome/midline congestion for cases of hematuria and cpps? In fact, one thing I read is that it CAUSES cpps.

Any thoughts?
