Kidney deficiency and kidney failure are two different concepts, they represent different disease states.

Kidney deficiency is a concept in traditional Chinese medicine theory, which refers to insufficient or weak kidney function of the human body. Traditional Chinese medicine believes that kidney is the root of life, with the function of regulating, storing and secreting important substances. Kidney deficiency can lead to a series of symptoms, such as sore waist and weak legs, fatigue, frequent urination at night, tinnitus, etc. Kidney failure is a disease state, which refers to the loss or significant decline of kidney function, unable to properly complete the elimination of metabolites and maintain the stability of the internal environment.
