What is orthostatic proteinuria?

Orthostatic proteinuria may be related to functional causes, nutcracker phenomenon, early manifestations of certain glomerular diseases, etc., specific analysis is as follows:

1, functional causes

Due to the existence of microcirculation changes in the patient's kidney, resulting in a large number of protein filtration glomerulus into the urine, causing orthostatic proteinuria.

2, nutcracker phenomenon

Due to the existence of abdominal aorta and its branches between the mesenteric artery angle is small, will compress the left renal vein, causing high pressure in the left kidney, appear to do left kidney congestion, increase glomerular capillary permeability, increase protein filtration, orthostatic proteinuria.

3, early manifestations of certain glomerular diseases

due to the existence of acute glomerulonephritis, nephrotic syndrome, chronic glomerulonephritis and other glomerular diseases, will destroy glomerular filtration function, causing a large number of protein leakage into the urine, resulting in orthostatic proteinuria.
