Renal vascular ultrasound is an ultrasound examination that allows assessment of the blood vessels supplying the kidneys and detection of blood flow disorders such as renal artery stenosis (narrowing), thrombosis, or aneurysms. This method is safe and highly effective for diagnosing diseases of the renal vessels and evaluating their impact on kidney function.
When is renal vascular ultrasound indicated?
Renal vascular ultrasound may be recommended in the following cases:
- Hypertension (high blood pressure) — persistent elevation of blood pressure may be caused by impaired renal blood flow, for example due to renal artery stenosis.
- Edema — swelling of the legs, face, or abdominal area may indicate impaired kidney function related to reduced blood supply.
- Impaired kidney function — such as elevated blood creatinine or urea levels, which may be associated with vascular problems affecting renal perfusion.
- Lower back or abdominal pain — pain in the kidney region may be related to vascular pathologies such as thrombosis or aneurysms of renal vessels.
- Suspected renal vascular disease — for example, suspected atherosclerosis or other vascular conditions that may compromise normal renal blood flow.
- Monitoring of patients with chronic kidney disease — including chronic kidney disease, diabetic nephropathy, or follow-up after kidney surgery.
Advantages of renal vascular ultrasound
- Safety — ultrasound does not use ionizing radiation, making it safe for all patients, including pregnant women and children.
- Accuracy — renal vascular ultrasound allows detection of conditions such as renal artery stenosis, aneurysms, thrombosis, and structural changes of vessel walls.
- Painlessness — the procedure is completely painless and does not cause discomfort.
- Accessibility — renal vascular ultrasound is available in most medical institutions and usually takes only 15–20 minutes.
How is renal vascular ultrasound performed?
The procedure is carried out using an ultrasound transducer that is moved over the patient’s abdominal and lumbar regions. A special gel is applied to the skin to improve transmission of ultrasound waves. The examination allows not only assessment of the kidneys themselves but also visualization of the blood vessels, including the renal arteries and veins.
To obtain the most accurate results, the patient may be referred for additional studies, such as Doppler ultrasound, to assess blood flow within the renal vessels.
Renal vascular ultrasound is available in leading clinics in Belarus, where specialists provide high-quality diagnostics and offer individualized treatment recommendations.
