Our renal artery stenosis ultrasound scans assess blood flow in the renal arteries, helping to diagnose and monitor narrowing or blockages that can affect kidney function.
Individuals with risk factors for renal artery stenosis, such as high blood pressure (especially if resistant to treatment), older age, atherosclerosis, or a history of smoking, may benefit from a renal artery stenosis ultrasound scan. The scan is also recommended for those with unexplained kidney dysfunction, sudden or rapidly worsening hypertension, or a significant difference in kidney sizes. Renal artery stenosis ultrasound scans can help identify narrowing or blockages in the renal arteries, allowing for timely intervention to preserve kidney function and manage associated conditions like hypertension.
During a renal artery stenosis ultrasound scan, you'll lie comfortably on an examination table with your abdomen exposed. A clear, water-based gel will be applied to your skin, and a handheld device called a transducer will be moved over your abdomen to capture detailed images of the renal arteries and assess blood flow using Doppler technology. The radiologist may ask you to hold your breath briefly or change positions to better visualise the renal arteries from different angles. The procedure is painless and usually takes 30-45 minutes, depending on the extent of the examination.
You may be asked to fast for 6-8 hours before your renal artery stenosis ultrasound scan to minimise gas in the intestines, which can interfere with the imaging. Drink plenty of water before the exam to ensure adequate hydration and to promote clear visualisation of the renal arteries. Wear loose, comfortable clothing that allows easy access to your abdomen. Inform your radiologist of any relevant medical history, current medications (especially blood pressure medications), or allergies, as this may impact the interpretation of the results. If you have any concerns or questions about the procedure, feel free to discuss them with your radiologist before the scan.
If you have risk factors for renal artery stenosis or experience symptoms such as resistant hypertension, unexplained kidney dysfunction, or a significant difference in kidney sizes, schedule your renal artery stenosis ultrasound scan as soon as possible. Early detection and management of renal artery stenosis can help preserve kidney function and prevent complications. Your GP or nephrologist will advise you on the appropriate timing based on your individual circumstances and the presence of any concerning symptoms. If you have been diagnosed with renal artery stenosis, your specialist may recommend regular scans to monitor the progression of the condition and assess the effectiveness of treatment.
We provide a comprehensive range of services, from private GP consultations and specialised men's and women's health care to advanced ultrasound scans and proactive health screenings, all within a reassuring and state-of-the-art environment.
You have a question? We have an answer.
Whilst a renal artery stenosis ultrasound scan is primarily focused on evaluating the renal arteries, it can sometimes detect other kidney abnormalities, such as kidney stones, cysts, or tumours. However, these findings are incidental and may require further targeted imaging or tests for a definitive diagnosis. If you have concerns about other kidney conditions, discuss them with your radiologist or GP to determine the most appropriate diagnostic approach.
No, a renal artery stenosis ultrasound scan is generally painless. You may feel slight pressure from the transducer as it moves over your abdomen, but this should not cause any significant discomfort. If you experience pain during the procedure, inform your radiologist, as this may indicate an underlying condition that requires further investigation.
You may be asked to fast for 6-8 hours before your renal artery stenosis ultrasound scan to minimise gas in the intestines, which can interfere with the imaging. However, it's important to drink plenty of water before the exam to ensure adequate hydration and to promote clear visualisation of the renal arteries. Your radiologist will provide you with specific instructions regarding eating and drinking before the scan based on your individual circumstances.

An ultrasound scan, also known as sonography, is a medical imaging technique that uses high-frequency sound waves to create images of the inside of the body. It is a safe and painless procedure that does not use ionising radiation. Ultrasound scans are commonly used to monitor pregnancy, diagnose conditions, and guide medical procedures. The images are created in real-time, allowing healthcare professionals to view the structure and movement of internal organs and tissues.
During an ultrasound scan, a small device called a transducer is placed on the skin over the area to be examined. The transducer emits high-frequency sound waves that travel through the body and bounce back when they encounter different tissues. The transducer then receives these reflected waves and converts them into electrical signals, which are processed by a computer to create images of the internal structures. The images can be displayed on a monitor or printed for further analysis.
Yes, ultrasound scans are generally considered safe for both the patient and the unborn baby (in the case of pregnancy scans). Unlike X-rays or CT scans, ultrasound does not use ionising radiation, which can potentially harm living tissues. There are no known side effects or risks associated with ultrasound scans when performed by qualified healthcare professionals. However, it is essential to ensure that the scan is medically necessary and performed by a trained specialist.
There are several types of ultrasound scans, each designed for specific purposes:
Abdominal ultrasound: Used to examine organs in the abdomen, such as the liver, gallbladder, pancreas, and kidneys.
Pelvic ultrasound: Used to assess the uterus, ovaries, and other pelvic structures in women, or the prostate gland in men.
Pregnancy ultrasound: Used to monitor fetal development, confirm the due date, and detect potential complications.
Breast ultrasound: Used to evaluate breast lumps or abnormalities detected during a mammogram or physical exam.
Vascular ultrasound: Used to assess blood flow in arteries and veins and detect blockages or clots.
According to verified reviews from platforms such as Doctify, TrustPilot and Google - 99% patients have a positive experience at Spital Clinic.
"Great experience. Frustratingly we had 3 NIPTs come back with no result so had to do 3 blood redraws but thanks to LPC’s persistence we finally got a result on the 4th draw. After the 3rd no result they also kindly offered us a free anomaly scan."
"I had a surprisingly positive experience. The most friendly and helpful staff, clean and beautiful premises. The visit was smooth and quick but never felt rushed and I was able to ask all the questions I had. Thanks so much!"
"The service was exceptional from the moment we booked to the moment we left the building post our appointment. The lovely colleagues at the main desk were great and approachable. They made the whole process very comforting."
"I really recommend this clinic, everything was smooth and perfect. All staff are helpful and our sonographer Miss Shaz is an expert on her job, she is very kind and explained everything that we asked. I am glad to choose LPC."
Our medical centre is at 36 Spital Square, E1 6DY, City of London.
