What procedure is used to replace some functions of the kidneys?

Dialysis is a procedure specifically designed to replace some of the functions of the kidneys. This treatment is essential for patients who have chronic kidney disease or acute kidney injury. The primary role of the kidneys is to filter waste products and excess fluid from the blood, maintaining the body’s chemical balance. When kidneys are no longer able to perform these functions effectively, dialysis steps in to remove waste products, regulate electrolytes, and manage fluid levels in the body.

There are two main types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis involves filtering the blood through a machine, while peritoneal dialysis uses the lining of the abdominal cavity to filter blood inside the body. Both types of dialysis help mimic the kidney functions, allowing patients to manage their condition and maintain a level of normalcy in their daily lives. As such, dialysis is the correct answer, as it directly corresponds to the need for a procedure that takes over some of the kidney functions. This is crucial for those who cannot rely on their kidneys for proper filtration and fluid balance.
