2. Renal artery stenosis - Wikipedia

   en.wikipedia.org/wiki/Renal_artery_stenosis

   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 .

3. Hypertensive kidney disease - Wikipedia

   en.wikipedia.org/wiki/Hypertensive_kidney_disease

   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 ...

4. Acute kidney injury - Wikipedia

   en.wikipedia.org/wiki/Acute_kidney_injury

   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

5. Renal infarction - Wikipedia

   en.wikipedia.org/wiki/Renal_infarction

   Renal infarction is a medical condition caused by an abrupt disruption of the renal blood flow in either one of the segmental branches or the major ipsilateral renal artery. [3] Patients who have experienced an acute renal infarction usually report sudden onset flank pain , which is often accompanied by fever , nausea , and vomiting .

6. Acute tubular necrosis - Wikipedia

   en.wikipedia.org/wiki/Acute_tubular_necrosis

   Ischemic ATN can be caused when the kidneys are not sufficiently perfused for a long period of time (i.e. renal artery stenosis) or during shock. Hypoperfusion can also be caused by embolism of the renal arteries. Given their importance in massive nutrient and electrolyte reabsorption, the proximal tubule and medullary thick ascending limb ...

7. Kidney ischemia - Wikipedia

   en.wikipedia.org/wiki/Kidney_ischemia

   Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]

8. Nutcracker syndrome - Wikipedia

   en.wikipedia.org/wiki/Nutcracker_syndrome

   [1] [2] The name derives from the fact that, in the sagittal plane and/or transverse plane, the SMA and AA (with some imagination) appear to be a nutcracker crushing a nut (the renal vein). There is a wide spectrum of clinical presentations and diagnostic criteria are not well defined, which frequently results in delayed or incorrect diagnosis. [1]

9. Radioisotope renography - Wikipedia

   en.wikipedia.org/wiki/Radioisotope_renography

   Radioisotopes can differentiate between passive dilatation and obstruction. It is widely used before kidney 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, [12] and later the performance of the transplant.
