Maintenance of urine output in hemodialysis patients requires continued treatment of the primary cause of kidney failure, control of water intake, and avoidance of infection.
Early hemodialysis patients often have residual renal function, when there is still a certain amount of urine output that needs to be maintained, which has a good effect on the patient’s quality of life and life expectancy. Primary causes of renal failure (e.g. diabetes mellitus), excessive and rapid dehydration during hemodialysis, and infections are the main causes of damage to residual renal function.
1. Primary disease: If the primary disease of kidney failure cannot be effectively controlled, it will continue to damage the residual kidney tissue and needs to be controlled, such as using insulin to control the blood sugar of diabetic patients. In addition, we should also pay attention to the control of hypertension, hyperuricemia and so on.
2. Too much and too fast dehydration: too much and too fast dehydration in the process of hemodialysis will cause the blood volume to drop in a short time, affecting the renal blood supply, and further destroying the residual renal function, so the patients usually need to control the intake of water, so as not to accumulate a large amount of water in the body, and if possible, can increase the number of hemodialysis, in order to slow down the rate of dehydration.
3. Infection: all kinds of infections, including lung infection, urinary tract infection, will further damage the kidneys, so patients usually need to avoid all kinds of infections, if there is fever and cough and other discomforts, need to consult a doctor in time.
In addition to these measures, patients need to avoid high or low blood pressure and avoid using drugs that are toxic to the kidneys.
Patients with hemodialysis should go to the hospital regularly every week for standardized treatment under the guidance of dialysis physician to avoid delaying the condition.
