What is the term used when kidneys can no longer cleanse the blood and maintain homeostasis?

The term "Kidney Failure" is used to describe a condition in which the kidneys lose their ability to properly cleanse the blood and maintain homeostasis. In this state, the kidneys cannot filter waste products effectively, leading to the accumulation of toxins in the body. This impaired function can be due to various underlying causes, including diabetes, hypertension, or other kidney-related conditions.

Choosing "Kidney Failure" emphasizes the severity of the situation as it indicates that the kidneys are no longer meeting the body's needs for waste elimination and balance of bodily fluids and electrolytes. This encompasses both acute and chronic forms of renal failure.

The other terms, while related, do not capture the full essence of the complete inability of the kidneys to perform their critical functions in the context described. Acute Renal Failure indicates a sudden onset of kidney dysfunction, Chronic Kidney Disease denotes a gradual loss of kidney function over time, and Nephropathy refers more generally to any disease of the kidneys without specifying the level of failure.
