Kidney failure (renal failure) means one or both of your kidneys no longer function well on their own. Kidney failure is sometimes temporary and develops quickly (acute). Other times it’s a chronic (long-term) condition that slowly gets worse.
Kidney disease is called “chronic” because kidney function slowly decreases over time. CKD can lead to kidney failure, which is also called end-stage kidney disease. Not everyone with CKD will develop kidney failure, but the disease will often worsen without treatment. There’s no cure for chronic kidney disease.
Uremia is a buildup of waste products in your blood that occurs as a result of untreated kidney failure. Symptoms include nausea, vomiting, weight loss, difficulty concentrating and fatigue. Treatments include dialysis and kidney transplant surgery. Without treatment, uremia is fatal.
Renal osteodystrophy is a complication of chronic kidney disease that weakens your bones. It's caused by changes in the levels of minerals and hormones in your blood. The main signs are bone pain and fractures.
Renal hypertension (or renovascular hypertension) is high blood pressure caused by the narrowing of your arteries that carry blood to your kidneys. It is also sometimes called renal artery stenosis. Because your kidneys are not getting enough blood, they react by making a hormone that makes your blood pressure rise.
Hepatorenal syndrome (HRS) is a life-threatening complication of end-stage liver disease. It causes sudden kidney failure in people who had no prior kidney disease.
Monoclonal gammopathy of renal significance (MGRS) is a group of conditions caused by a buildup of faulty antibodies (M proteins) in your kidneys. The buildup can cause severe kidney damage. Symptoms can include frothy or pink-tinged pee and swelling in your legs, ankles and feet. Treatment aims to prevent further damage to your kidneys.
Anuria is the lack of urine (pee) production. It can happen as a result of shock, severe blood loss, or heart or kidney failure. It can also occur from medications or toxins. Anuria is an emergency and can be life-threatening. Get immediate treatment if you have anuria.
Is azotemia the same as renal failure? No, azotemia isn’t the same as kidney failure (renal failure). Kidney failure is the main cause of azotemia. How common is azotemia? Azotemia is common. It accounts for about 16% of hospital admissions.
Kidney failure (renal failure): Kidney failure may be acute (worsen suddenly) or chronic (a permanent lessening of how well your kidneys work). End-stage renal disease is a complete loss of kidney function. It requires dialysis (treatment to filter your blood in place of your kidneys).
