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 .

This leads to a build-up of plaques and they can be deposited in the renal arteries causing stenosis and ischemic kidney disease. [citation needed] In this situation, the kidney supplied blood by the narrowed renal artery suffers from inadequate blood flow, which in turn causes the size of the kidneys to decrease. Other consequences include ...

This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Generally, diseases outlined within the ICD-10 codes N00-N19, N20.0 within Chapter XIV: Diseases of the genitourinary system should be included in this category. Wikimedia Commons has media related to Kidney diseases .
[8] [9] [10] There are two main causes of renovascular hypertension: renal artery stenosis and fibromuscular dysplasia. [citation needed] The normal physiological response to low blood pressure in the renal arteries is to increase cardiac output (CO) to maintain the pressure needed for glomerular filtration. Here, however, increased CO cannot ...
The latter include renal artery stenosis, or the narrowing of the renal artery which supplies the kidney with blood, and renal vein thrombosis, which is the formation of a blood clot in the renal vein that drains blood from the kidney. [10]: 26-27
