A significant association between hypertension-related indications and RAS-positive studies was shown (p=.002).Ĭonclusion: RHDUS is a useful screening test in patients with a high suspicion of RAS. Sensitivity and specificity was 80% and 98.5% respectively. Twenty-one of the studies met criteria for possible RAS. Results : 291 (90%) of 325 Doppler studies were included in the study. Renal Doppler results and confirmatory studies such as Angiography, MRA, CTA, etc.
Patients’ sex, age, serum creatinine and BUN, risk factors for RAS, and primary and secondary indications for the requested Doppler exam were included. Patients receiving RHDUS were included with the exclusion of patients under 18 years, and exams of poor diagnostic quality. Materials and methods : A retrospective study of adult Intensive Care Unit (ICU) patients receiving RHDUS to rule out RAS spanning a time frame of one year.

Vinmec International General Hospital is one of the hospitals that not only ensures professional quality with a team of leading medical doctors, modern equipment and technology, but also stands out for its examination and consultation services. This is a non-invasive, economical, fast effective and safe measure for the patient's health. Indications for renal artery Doppler ultrasound in the following diseases: Renal host disease Obstructive kidney disease Renal artery stenosis Renal tumor Kidney transplant patient Renal artery ultrasound and renal artery Doppler ultrasound have plays a huge role in the diagnosis and treatment of many kidney diseases as well as in monitoring the health status of kidney transplant patients.
RI in children, especially infants, is often higher than in adults.
The RI index was measured at the upper, lower and lower poles of the kidney on each side, then the average value was calculated to assess the degree of obstruction of renal blood flow at the downstream site. One of the parameters to be considered in the Doppler ultrasound of the renal arteries is the RI contrast index to represent the wave shape in ultrasound. The probe position on the patient's abdomen is usually the anterior, lateral line when the patient is supine or lateral. Some patients who are having difficulty breathing due to other medical conditions cannot perform a renal artery Doppler ultrasound. In these cases it is difficult to visualize the renal artery, so only the interlobar artery can be explored.
Because the renal artery has an anatomical position located very deep inside the abdomen, it is difficult to use an ultrasound probe to investigate, especially in obese patients. To perform a renal artery Doppler ultrasound, the patient needs to fast for 6 hours, not drink any carbonated drinks before the ultrasound. In addition, other kidney diseases are often performed renal artery ultrasound in combination with some other methods to diagnose and monitor disease status. To diagnose this pathology, renal artery ultrasound and renal artery Doppler ultrasound are one of the most effective non-invasive clinical methods today. Renal artery stenosis is one of the causes of high blood pressure, accounting for 5-10%. In particular, renal artery stenosis is a disease caused by the narrowing of the inner lumen of the renal artery, reducing the blood flow to the renal artery, increasing the blood pressure of the renal artery, thereby causing dangerous diseases such as heart failure. can seriously affect the patient's life, so the examination and treatment Diagnosis of these diseases is essential. Kidney diseases such as renal artery stenosis, renal host disease, obstructive kidney disease, kidney tumor.
