Nutcracker syndrome is generally not a particularly serious disease, some patients can be treated conservatively, while a small number may need surgery or intervention. Nutcracker syndrome, or left renal vein compression syndrome, occurs when the left renal vein is compressed and symptoms such as hematuria, proteinuria, and low back pain occur. Most pediatric patients can be treated conservatively, and it is possible that as the child grows older the increase in fat and knotted tissue at the beginning of the superior mesenteric artery will reduce the compression and the hematuria will disappear. When the symptoms are not relieved by conservative treatment, surgical treatment or interventional stenting can also be used to relieve the compression of the left renal vein, remove renal vein stasis, and improve the blood supply to the kidneys. Therefore, when Nutcracker Syndrome occurs, go to a regular hospital and follow the doctor’s instructions for treatment.
