Renal Disease

Expert treatment for kidney artery blockages and renovascular conditions

Vascular Surgery

Kidney Blood Flow

Renal artery stenosis can cause high blood pressure and kidney dysfunction. Expert vascular intervention can restore normal kidney function and blood pressure control.

Understanding Renal Vascular Disease

The kidney is a bean-shaped organ that lies within the abdomen. They serve many functions including filtering impurities from the blood to produce urine, regulation of plasma electrolytes and acid-base balance, regulation of blood pressure and production of some hormones.

The kidneys receive their blood supply usually by a single renal artery, that branches from the abdominal aorta.

Kidney Vascular Anatomy

Renal Arterial System

Causes of Renal Artery Stenosis

Stenoses of the arteries to the kidneys may be caused by the following

Atherosclerosis

Most common cause of renal artery stenosis

Cholesterol plaque buildup
Progressive arterial narrowing
Usually affects older patients

Fibromuscular Disease

Non-atherosclerotic arterial disease

More common in younger women
Abnormal arterial wall development
Often responds well to intervention

Inflammatory Arteritis

Inflammatory conditions affecting arteries

Takayasu arteritis
Giant cell arteritis
Requires specialized treatment

Symptoms

Stenosis of the arteries to the kidneys may be asymptomatic, or may cause the following problems

Silent Condition

Often Asymptomatic

Many cases of renal artery stenosis can be present without obvious symptoms, making regular health screenings important for early detection.

Renal Symptoms

Symptomatic Presentations

High Blood Pressure

Renovascular hypertension that may be difficult to control

Sudden Pulmonary Oedema

Acute fluid buildup in the lungs

Chronic Renal Failure

Progressive decline in kidney function

Investigations

Stenoses of the arteries to the kidneys can be identified and monitored with various imaging techniques

Renal Duplex Ultrasound

Duplex Ultrasound

Non-invasive first-line screening test

CT Angiography

CT Angiography

Detailed cross-sectional imaging of renal vessels

MR Angiography

MR Angiography

High-resolution magnetic resonance imaging

Catheter Angiography

Catheter Angiography

Gold standard for detailed renal vessel assessment

Treatment Options

Individualized Treatment Planning

After review of your history, physical examination and investigations we will formulate an appropriate treatment plan for you. Stenoses of the renal arteries can be treated by a number of means.

Medical Management

Medications to control blood pressure and protect kidney function.

Antihypertensive medications
Cholesterol lowering medications
Antiplatelet medications

Endovascular Techniques

Minimally invasive procedures to open blocked renal arteries.

Renal artery angioplasty and stenting

Surgical Options

Open surgical procedures for complex cases.

Renal artery bypass
Complex reconstruction
Renal Angioplasty

Renal Angioplasty & Stenting

Endovascular techniques such as angioplasty and stenting offer minimally invasive treatment options for renal artery stenosis.

Balloon dilation of narrowed artery
Stent placement for long-term patency
Faster recovery than surgery
Renal Bypass Surgery

Surgical Reconstruction

Surgery, such as bypass, may be required for complex lesions or failed endovascular treatment.

Bypass grafting around blockage
Excellent long-term durability
