title: Retroaortic left renal vein with renal vein hypertension causing hematuria.
abstract: We describe a case of retroaortic left renal vein with hematuria. In this case, pullback pressure from the retroaortic left renal vein to the inferior vena cava revealed left renal vein hypertension according to criteria of the "nutcracker phenomenon." We stress that left renal vein anomaly including retroaortic left renal vein can cause clinical symptoms such as hematuria.
