Renal Nutcracker syndrome is usually not serious. The renal vein, on its way back into the inferior vena cava, passes through the angle formed by the superior mesenteric artery and the abdominal aorta. If this angle is small, like a nutcracker, it tends to snag on the renal vein leading to kidney stasis, and a nutcracker syndrome is formed. The formation of nutcracker syndrome is related to the lean body type and low fat content in the abdomen of patients. After patients pay attention to their diet and gradually gain weight, many nutcracker syndromes are cured. Some patients are not cured, but the prognosis for this disease is relatively good in the long run, and the chance of developing into renal failure is very small, so there is no need to worry too much. With Nutcracker syndrome it is recommended to dynamically review urine routine, kidney function and ultrasound, if the above indicators keep getting worse, surgery can be taken if necessary.
