Makroskopik Hematürinin Nadir Bir Nedeni: Nutcracker Sendromu.

Nutcracker syndrome caused by compression of the left renal vein between the abdominal aorta and the superior mesenteric artery is a rare anatomo-pathological condition. The patients have symptoms such as hematuria, proteinuria, and left flank pain. In this paper, we report a 13-year-old boy who presented with macroscopic haematuria. Routine laboratory tests for the evaluation of hematuria were normal. Abdominal computed tomography revealed that the left renal vein was compressed between the aorta and the superior mesenteric artery. A diagnosis of nutcracker syndrome was established. If Nutcracker syndrome is considered in the differential diagnosis of haematuria, it is easily diagnosed by imaging techniques. [ABSTRACT FROM AUTHOR]
