Most of the patients with chronic renal failure still have some renal function, protect the residual renal function can reduce the frequency of dialysis, more conducive to maintaining the body's water and electrolyte balance and reduce the incidence of cardiac dysfunction.
1. Actively treat the primary disease
Different causes of kidney disease, the degree of residual renal function decreased slightly. Early diabetic nephropathy to actively strengthen insulin therapy, can slow down the residual renal function decline. Lupus nephritis, renal function after hormone shock treatment may also be restored, and even have a longer time from dialysis. Purpura nephritis should actively look for allergens, to prevent re-sensitization aggravate renal damage.
2. Strict control of high blood pressure
Hypertension is a factor that promotes the progression of kidney disease, especially in dialysis patients, prone to water retention and dyslipidemia, both of which are risk factors for increased blood pressure and renal arteriosclerosis, glomerular damage caused by further.
3. Prevent low blood pressure in hemodialysis
In dialysis to remove water should not be too much, usually 5-7% of body weight is appropriate to prevent hypotension. Because of insufficient blood volume, can make the kidneys further ischemia, aggravating kidney damage. Patients are required to control the dialysis interval.
4. Remove the obstruction of the kidney
Elderly male should pay attention to the treatment of benign prostatic hypertrophy, kidney and ureteral stones should be removed as soon as possible.
5. Avoid kidney drugs and poisons
Many drugs and poisons have kidney damage. Such as aminoglycoside antibiotics, rifampin in anti-tuberculosis drugs, antineoplastic drug doxorubicin, fluorouracil, high-dose antipyretic and analgesic agents such contrast agent, mannitol, traditional Chinese medicine Caulis aristolochiae manshuriensis and Aristolochia fangchi. Fish gallbladder, mercury and other heavy metals.
6. Avoid high-protein diet, high purine diet
High-protein diet has the effect of increasing the burden on the kidneys. Renal failure patients without dialysis are appropriate to take low-protein diet. However, dialysis patients due to small molecules of nutrients will be lost through the filtration membrane, it is not recommended to take low-protein diet, appropriate high protein diet should be given under the guidance of doctors to prevent malnutrition.
High-purine diet can increase uric acid, the formation of uric acid crystals block the renal tubular damage. Such foods are: animal offal, seafood, fish eggs, skin, beer, soybeans, seaweed, mushrooms, spinach and so on.
