Nutcracker phenomenon is left renal vein compression, more frequently in the angle formed by the aorta artery and the superior mesenteric artery due to abnormal emergency of the mesentery. When symptoms derived from this anomaly occur, this situation is called nutcracker syndrome. It may cause very varied symptoms and signs such as hematuria, orthostatic proteinuria, varicocele, chronic pelvic congestion, abdominal pain and flank pain, and orthostatic intolerance as the most common ones. Hematuria and orthostatic proteinuria are two frequent manifestations that the family physician and the pediatrician must face, so it is necessary to take the nutcracker syndrome into account for the differential diagnosis of these alterations. Hematuria is more frequent and orthostatic proteinuria is mainly caused by the nutcracker syndrome. Therefore, we consider that this brief review on this topic is important to cope with these situations and to bear in mind all their diagnostic possibilities.
