I. Diet: 1. Protein: The metabolites in the human body are mainly derived from the protein components of the diet, especially animal and plant proteins, such as meat, rice, flour and soy products. Therefore, in order to reduce the workload of the residual healthy kidney units, protein intake must be compatible with the excretory capacity of the kidneys. However, it must be emphasized that if restricting protein intake is pursued, it will lead to malnutrition and decrease in body mass, which is not good. Therefore, under the premise of reducing the total protein intake, it is necessary to selectively supplement the protein with high nutritional value, the so-called high-quality protein, in order to meet the necessary nutritional needs of the body. The specific approach is generally to increase the intake of certain animal proteins (such as milk, eggs, fish, lean meat, etc.) and reduce the amount of plant proteins, because the former contains a higher variety and quantity of essential amino acids than the latter. Since grain contains a lot of plant protein, it is recommended that starchy foods, such as wheat starch, corn starch, lotus root flour, potatoes, yams, etc. (protein content is only 0.4%), instead of ordinary rice, noodles and other staple foods (protein content is 7-10%). 2, heat: to make the maximum use of the protein intake, not to let it be converted into energy consumption, in taking a low protein diet, but also must be supplemented with energy. At least 35 calories per kilogram of body weight per day. Calories are mainly supplied by sugar, you can eat fruit, cane sugar products, chocolate, jam, honey, etc. Fat can also provide some of the calories, vegetarian oils can be unrestricted. 3, phosphorus: in the supplemental protein also need to pay attention to some food although meet the above conditions, such as: egg yolk, meat loaf, animal offal, dairy products, bone marrow, etc., because of the high phosphorus content, but still should not be eaten, because the retention of phosphorus can contribute to the kidney function is reduced. To reduce the amount of phosphorus in food, consumption of fish, meat, potatoes, etc., can be boiled first to discard the soup before further cooking. 4, salt: the amount of salt should depend on the condition, such as hypertension, edema, it is appropriate to use a low-salt diet, 2 grams of salt per day. If polyuria, the amount of sodium and salt lost in urine should be calculated according to the daily amount of sodium and salt lost in urine after discretion. 5. Water: The kidneys excrete metabolic wastes from the body by secreting urine. Only by ensuring sufficient urine volume (generally 2000ml/day or more) can the metabolic products of the day be excreted, therefore, if there is no obvious edema, more water should be drunk, and it is recommended to ensure 2000ml of water per day in addition to water in the excluded food. II. Exercise: Proper exercise is necessary to keep the body healthy. However, strenuous exercise needs to be avoided because strenuous exercise is likely to cause a lot of sweating, causing changes in circulating blood volume during a period of time, and is likely to cause large fluctuations in heart rate and blood pressure, which can easily increase the load on the kidneys. In addition to small-intensity exercise such as walking, it is recommended that slightly more intense exercise, such as jogging, swimming, etc.; 3. Health care: 1. On review: It is recommended to review ultrasound in January after discharge, CT after three months, and ultrasound/CT every six months thereafter, as well as blood biochemistry to clarify renal function. 2, daily monitoring: blood pressure: pay attention to the monitoring of blood pressure, high blood pressure may cause damage to kidney function, therefore, blood pressure should be controlled to avoid dramatic fluctuations in blood pressure; urine volume: urine volume is the most direct manifestation of kidney function, if there is a decrease in urine volume (in the case of normal water intake), renal function should be reviewed in a timely manner, and timely intervention. 3, drugs: the vast majority of drugs are metabolized through the liver and kidneys, therefore, to avoid the application of drugs with high nephrotoxicity, while the application of drugs that are mainly metabolized through the kidneys, the application needs to follow medical advice.
