If a person with kidney takes care of kidney protection, no problem will occur. It can live as normal and live as long as a normal person. Because the kidneys have a strong compensatory capacity, normally only 30% of kidney units are actually working, and the remaining 70% are in a state of rest in rotation. One kidney is fully capable of performing the excretory and secretory functions of the kidney, removing metabolites and toxins from the body, and maintaining hydropower and acid-base balance. But after all, it is one kidney, which requires patients to have a long-term light, low-salt, low-fat, low-purine, high-quality protein diet and maintain normal body weight to prevent vascular sclerosis causing sclerosis of renal arteries and glomeruli. Regular check of blood sugar and blood pressure, urinary routine, renal function and renal ultrasound are also required, and nephrotoxic drugs need to be avoided throughout the course of the disease.
