What Is Renal Vascular Disease?
Renal vascular disease includes conditions that affect blood flow to and from the kidneys. When blood vessels become narrowed, blocked, or damaged, the kidneys may not receive enough blood to work properly.
Several health conditions can increase the risk of renal vascular disease, including:
- Atherosclerosis (hardening of the arteries)
- Diabetes
- Smoking
- High cholesterol
- Obesity
- Long-term high blood pressure
- Blood clotting disorders
- Certain inherited or inflammatory conditions
Over time, reduced kidney blood flow can lead to high blood pressure, kidney damage, or kidney failure. Some forms of renal vascular disease also increase the risk of heart and blood vessel problems.
Symptoms
Symptoms of renal vascular disease can vary depending on the type and severity of the condition. Some people may not notice symptoms early on.
Common symptoms include:
- High blood pressure that is difficult to control
- Swelling in the legs, feet, or body
- Flank or side pain
- Blood in the urine
- Fatigue
- Nausea
- Sudden changes in kidney function
How Is It Diagnosed?
Healthcare providers diagnose renal vascular disease using a combination of physical examination, lab work, and imaging tests.
Testing may include:
- Blood and urine tests to evaluate kidney function
- Duplex ultrasound to check blood flow
- CT or MR angiography
- Renal angiogram in some cases
These tests help identify narrowed arteries, blood clots, or other problems affecting kidney circulation.
How Is It Treated?
Treatment focuses on improving blood flow, protecting kidney function, and reducing the risk of complications.
Treatment options may include:
- Blood pressure medications
- Cholesterol-lowering medicine
- Diabetes management
- Blood thinners for clot-related conditions
- Lifestyle changes such as quitting smoking and reducing salt intake
Some people may need procedures to improve blood flow, including:
- Angioplasty
- Stent placement
- Surgery for severe blockages or aneurysms
If kidney damage becomes severe, dialysis or kidney transplant may eventually be needed.
Regular follow-up care is important to monitor kidney health and manage cardiovascular risk factors.
