Renal Vascular Disease

A primary cause of kidney damage and failure

Overview Of Renal Vascular Disease

When someone has renal vascular disease, their blood isn’t flowing normally to and from the kidneys. This can cause health complications including high blood pressure, kidney damage, and kidney failure.

Renal vascular disease involves the hormone renin, which raises blood pressure. When you have decreased blood flow to the kidneys due to renal vascular disease, you may have too much renin in the blood which results in excessively high blood pressure.

Renal vascular disease is related to the following conditions:

  • Renal artery stenosis (RAS), a narrowing of the artery to the kidneys 
  • Renal artery thrombosis, a blood clot in the artery to the kidney
  • Renal vein thrombosis, a clot in a vein to the kidney
  • Renal artery aneurysm, from a weak area in the wall of the artery to the kidney
  • Atheroembolic renal disease, from plaque breaking off and moving through the blood

Symptoms Of Renal Vascular Disease

A person with renal vascular disease may experience a wide array of symptoms, depending on how it is affecting their body. Any of the following symptoms can be an indicator of renal vascular disease:

  • Persistent high blood pressure, even despite medication
  • Blood with high urea, a waste byproduct of the kidneys
  • Sudden-onset side pain
  • Side and hip pain and tenderness
  • Belly pain
  • High and/or persistent fever
  • Blood in the urine
  • Nausea and vomiting  
  • Skin Lesions
  • Red or purple discoloration of the skin
  • Discoloration in the toes and feet
  • Diarrhea
  • Mental confusion
  • Unexplained weight loss
  • Muscle aches
  • Spasms in the body, especially the hips and flank
  • Soreness in the kidney area
  • Sudden or unexplained kidney failure    

It is important to note that some people with renal vascular disease have no symptoms. These patients are often diagnosed through routine medical screenings and checkups.
