Increased renal artery blood flow resistance index is usually associated with glomerulonephritis, nephrotic syndrome, renal insufficiency and other factors.
1. Glomerulonephritis: when the condition of glomerulonephritis is aggravated, affecting the glomerular filtration and leading to the stenosis of renal artery, the increase of renal artery blood flow resistance may be seen through examination.
2. Nephrotic syndrome: patients with nephrotic syndrome will have a large amount of proteinuria, if not treated in time, it may lead to a decrease in protein level, resulting in narrowing of the renal artery, which may show increased resistance to renal arterial blood flow through examination.
3. Renal insufficiency: when renal disease aggravates and affects renal function, resulting in renal insufficiency, it may affect the normal metabolism of the kidneys, narrowing the lumen of the renal artery, and the passage of the blood will be blocked, so that an increase in renal artery blood flow resistance will be found in the examination.
If patients find that the renal artery blood resistance index increases, it is recommended to go to the regular hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of doctors.
