WHAT IS A RENAL DUPLEX?
Renal Duplex is a color flow Doppler of kidney and renal arteries. The
renal arteries provide blood flow to the kidneys. Renal artery disease,
including narrowing (stenosis) due to atherosclerosis, can result in reduced
blood flow to the kidney. This can cause hypertension. Renal artery stenosis
is the most common correctable cause of hypertension. Long-standing,
untreated renal artery disease is also an important cause of kidney failure.
