Abstract

Nutcracker syndrome (NCS) refers to left renal vein compression with impaired blood outflow. The etiology of NCS has been attributed to various anatomic anomalies. Posterior NCS is caused by compression of the retroaortic left renal vein between the aorta and spine. The classic symptoms of NCS include left flank pain with gross or microscopic hematuria. The frequency and severity of the syndrome vary from asymptomatic microhematuria to severe pelvic congestion. For this reason, diagnosis of NCS is difficult and often delayed. Here, we report a case of posterior NCS that was incidentally discovered.
