Hypertension

high blood pressurehypertensivearterial hypertension
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.
The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such as chronic kidney disease, narrowing of the kidney arteries, an endocrine disorder, or the use of birth control pills.

Renovascular hypertension

hypertension, renovascularRenal hypertension
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.
The cause of renovascular hypertension is consistent with any narrowing/blockage of blood supply to the renal organ (renal artery stenosis).

Fibromuscular dysplasia

Renal artery stenosis is the narrowing of one of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.
In cases of renal stenosis and indications for intervention, percutaneous balloon angioplasty may be recommended.

Renal artery stenosis is the narrowing of one of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.
Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys.

Chronic kidney disease

Possible complications of renal artery stenosis are chronic kidney disease and coronary artery disease.
Vascular disease includes large vessel disease such as bilateral renal artery stenosis and small vessel disease such as ischemic nephropathy, hemolytic-uremic syndrome, and vasculitis.

It is used to assist in the diagnosis of renal artery stenosis.

Angioplasty

balloon angioplastyangioplastiespercutaneous transluminal angioplasty
When high-grade renal artery stenosis is documented and blood pressure cannot be controlled with medication, or if renal function deteriorates, surgery may be resorted to. The most commonly used procedure is a minimally-invasive angioplasty with or without stenting.
Renal artery stenosis can lead to hypertension and loss of renal function.

It is widely used before renal transplantation to assess the vascularity of the kidney to be transplanted and with a test dose of captopril to highlight possible renal artery stenosis in the donor's other kidney, and later the performance of the transplant.

Chronic condition

chronicchronic diseasechronic diseases
If the stenosis is longstanding and severe, the glomerular filtration rate in the affected kidneys never recovers and (prerenal) kidney failure is the result.

Renal function

If the stenosis is longstanding and severe, the glomerular filtration rate in the affected kidneys never recovers and (prerenal) kidney failure is the result. Decreased kidney function may develop if both kidneys do not receive adequate blood flow, furthermore some people with renal artery stenosis present with episodes of flash pulmonary edema.

The pathophysiology of renal artery stenosis, leads to changes in the structure of the kidney that are most noticeable in the tubular tissue.
