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]
The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
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 ...
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 ...
Renal hypoplasia; Other names: Hypoplastic kidneys: An ultrasound scan of a hypoplastic right kidney in an adult male. Specialty: Nephrology: Complications: Anuria, chronic kidney disease, glomerular hyperfiltration, hypertension, proteinuria, sepsis, urinary tract infection, urinary tract obstruction, urolithiasis [1] [2] Types
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 .
In medicine, a distal splenorenal shunt procedure (DSRS), also splenorenal shunt procedure and Warren shunt, [1] is a surgical procedure in which the distal splenic vein (a part of the portal venous system) is attached to the left renal vein (a part of the systemic venous system).
