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 .
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.
Chronic kidney disease–mineral and bone disorder ( CKD–MBD) is one of the many complications associated with chronic kidney disease. It represents a systemic disorder of mineral and bone metabolism due to CKD manifested by either one or a combination of the following: [1] [2] Abnormalities of calcium, phosphorus ( phosphate ), parathyroid ...
Kidney failure, also known as end-stage renal disease ( ESRD ), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. [ 2] Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney ...
Chronic kidney disease. Chronic kidney disease ( CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function occurs over a period of months to years, or abnormal kidney structure (with normal function). [ 2][ 5] Initially generally no symptoms are seen, but later symptoms may include leg swelling ...
Hyponatremia. Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [ 4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L ), with severe hyponatremia being below 120 mEq/L. [ 3][ 8] Symptoms can be absent, mild or severe. [ 2][ 9] Mild symptoms include a decreased ability to think ...
Renal osteodystrophy is currently defined as an alteration of bone morphology in patients with chronic kidney disease (CKD). [ 1] It is one measure of the skeletal component of the systemic disorder of chronic kidney disease-mineral and bone disorder (CKD-MBD). [ 1][ 2][ 3] The term "renal osteodystrophy" was coined in 1943, [ 4] 60 years after ...
Hypertensive kidney disease is a medical condition referring to damage to the kidney due to chronic high blood pressure. It manifests as hypertensive nephrosclerosis (sclerosis referring to the stiffening of renal components). [ 2] It should be distinguished from renovascular hypertension, which is a form of secondary hypertension, and thus has ...
