Renal Doppler in hypertension

This patient had severe hypertension. 

Renal Doppler ultrasound is essential to rule out renal artery stenosis. 

Let's see 👀 what we found:

Renal arteries diameter measurements are normal:

Caliber of both renal arteries is in normal range. 6 to 7 mm width. 

Let's have a look at arterial flow in both kidneys.

The intrarenal flow appears normal. 

Now let's have a look at renal arterial spectral Doppler in both kidneys:

Both renal arteries show normal waveform. High diastolic low resistance flow confirms 👍 healthy flow through renal arteries. 

Let's have a look at the segmental arteries of both kidneys. 

Looks like healthy normal flow parameters in the segmental arteries too.

Final diagnosis: 

Normal color and spectral Doppler ultrasound of both kidneys. 

He'll need to be investigated further to find the cause of hypertension.
