The amount of proteinuria in Nutcracker Syndrome is usually not too much, but it is possible to have a urine protein of 3+.
Nutcracker syndrome often refers to the left renal vein being compressed during its return to the inferior vena cava through the angle formed by the abdominal aorta and the superior mesenteric artery or the gap between the abdominal aorta and the spine, which may lead to a decrease in the speed of the left renal vein’s blood flow and a dilatation of the distal vein at the point of compression, as detected by renal ultrasound.
Clinical symptoms such as proteinuria, hematuria, and left lower back and abdominal pain may occur, and severe proteinuria may reach 3+.
When proteinuria, hematuria and other symptoms, especially adolescents, should be alert to the possibility of Nutcracker Syndrome, improve the urinary tract ultrasound and other related examinations, and standardized treatment under the guidance of the doctor.
