End-stage renal disease là gì

End-stage renal disease, also called end-stage kidney disease or kidney failure, occurs when chronic kidney disease — the gradual loss of kidney function — reaches an advanced state. In end-stage renal disease, your kidneys no longer work as they should to meet your body's needs.

Your kidneys filter wastes and excess fluids from your blood, which are then excreted in your urine. When your kidneys lose their filtering abilities, dangerous levels of fluid, electrolytes and wastes can build up in your body.

With end-stage renal disease, you need dialysis or a kidney transplant to stay alive. But you can also choose to opt for conservative care to manage your symptoms — aiming for the best quality of life during your remaining time.

How kidneys work

Show transcript for video How kidneys work

One of the important jobs of the kidneys is to clean the blood. As blood moves through the body, it picks up extra fluid, chemicals and waste. The kidneys separate this material from the blood. It's carried out of the body in urine. If the kidneys are unable to do this and the condition is untreated, serious health problems result, with eventual loss of life.

Symptoms

Early in chronic kidney disease, you might have no signs or symptoms. As chronic kidney disease progresses to end-stage renal disease, signs and symptoms might include:

• Nausea
• Vomiting
• Loss of appetite
• Fatigue and weakness
• Changes in how much you urinate
• Chest pain, if fluid builds up around the lining of the heart
• Shortness of breath, if fluid builds up in the lungs
• Swelling of feet and ankles
• High blood pressure [hypertension] that's difficult to control
• Headaches
• Difficulty sleeping
• Decreased mental sharpness
• Muscle twitches and cramps
• Persistent itching
• Metallic taste

Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. Because your kidneys can make up for lost function, signs and symptoms might not appear until irreversible damage has occurred.

When to seek care

Make an appointment with your health care provider if you have signs or symptoms of kidney disease.

If you have a medical condition that increases your risk of kidney disease, your care provider is likely to monitor your kidney function with urine and blood tests and your blood pressure during regular office visits. Ask your provider whether these tests are necessary for you.
