In 78 patients suspected of renovascular hypertension on clinical grounds duplex ultrasound examination of the renal arteries was performed. Renal angiography was used as the standard of reference.

In a prospective renal artery duplex ultrasound-based progression study, 84 patients with 139 renal arteries with stenosis were followed for a mean of 13 months. Progression of RAS occurred in 42% ...

Renal-artery stenosis may occur alone (isolated anatomical renal-artery stenosis) or in association with hypertension, renal insufficiency (ischemic nephropathy), or both.

Renal artery stenosis can lead to high blood pressure and kidney damage. Learn about its symptoms, causes, diagnosis, and treatment approaches.

New results from a clinical trial testing a novel ultrasound therapy for hypertension show the experimental treatment can deliver clinically meaningful reductions in blood pressure. The treatment ...

The renal segmental arterial resistance index (the percentage reduction of the end-diastolic flow as compared with the systolic flow) was measured by Doppler ultrasonography in 601 patients at ...

Renal artery stenosis (RAS) is the narrowing of one or both arteries carrying blood to the kidneys.

A kidney ultrasound uses high frequency sound to produce video and still images of your kidneys. Learn more about the process and its uses here.

An FDA advisory panel voted 10-2 that the benefits of an ultrasound renal denervation system outweigh the risk for use in adults with uncontrolled hypertension who are unresponsive or intolerant ...

Ultrasound renal denervation injures the sympathetic neurons within the renal artery that contribute to elevated blood pressure.

In addition, while renal arteriograghy is the accepted gold standard for diagnosing renal artery disease, it is well established that percentage angiographic diameter stenosis is an insensitive ...
