INTRODUCTION: Nutcracker syndrome (NCS) is a rare condition caused by the compression of the left renal vein between the abdominal aorta and superior mesenteric artery. The purpose of the study was to evaluate our management of NCS. METHODS: Patients were retrospectively reviewed and sex, age, main symptoms at application, physical examination, radiological findings, laboratory examinations, and treatment were recorded. RESULTS: 23 patients (16 girls, 7 boys; age range, 5 to 16) diagnosed with NCS. Microhematuria was detected with 14 (60.8%) patients before diagnosis. And four of 9 (39.1%) were determined after diagnosis. Microhematuria was not detected in 5 (21.7%) of the patients. All patients (100%) had orthostatic proteinuria. 17 (73.9%) patients had mild, 3 (13.0%) patients had moderate and 3 (13.0%) had severe proteinuria. The mean diameter of the left renal vein (LRV) at the aortomesenteric (AM) portions and the hilar were 1.69mm+-0.70 and 8.01mm+-2.27. The mean angle between the superior mesenteric artery and LRV was 25.26º+-7.98. DISCUSSION AND CONCLUSION: In the case of especially colic flank pain, hematuria, and proteinuria NCS should keep in mind in the differential diagnosis. Surgical management may supply more enough clinic improvement when the patient has a response to medical therapy.
