Renal sympathetic denervation (RSDN) is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation or ultrasound ablation aimed at treating resistant hypertension (high blood pressure not controlled by medication). [1]
Renal ultrasonography (Renal US) is the examination of one or both kidneys using medical ultrasound. Ultrasonography of the kidneys is essential in the diagnosis and management of kidney-related diseases. The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound.
Page kidney or Page phenomena is a potentially reversible form of secondary arterial hypertension caused by external compression of the renal parenchyma by some perirenal process. [1] Any process that causes mass effect can be a potential cause of Page kidney.
Hypertensive nephropathy refers to kidney failure that can be attributed to a history of hypertension [7] It is a chronic condition and it is a serious risk factor for the development of end-stage kidney disease (ESKD). However, despite the well-known association between hypertension and chronic kidney disease, the underlying mechanism remains ...
Upon presentation of decreased renal function, it is recommended to perform a history and physical examination, as well as performing a renal ultrasound and a urinalysis. [ citation needed ] The most relevant items in the history are medications , edema , nocturia , gross hematuria , family history of kidney disease, diabetes and polyuria .
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.
Applying spectral Doppler to the renal artery and selected interlobular arteries, peak systolic velocities, resistive index, and acceleration curves can be estimated (Figure 4) (e.g., peak systolic velocity of the renal artery above 180 cm/s is a predictor of renal artery stenosis of more than 60%, and a resistive index, which is a calculated ...
Small or absent kidney (renal agenesis), Ectopic kidneys (sometimes cannot be visualized by ultrasonography of abdomen due to intestinal gas) Evaluation of an occult duplex system, Characterization of certain renal masses, Evaluation of systemic hypertension especially young hypertensive and in cases of suspected vasculitis.
