Dialysis twice a week is already more serious, indicating that the kidney function has reached the end stage. For patients with chronic renal failure, long-term dialysis treatment is usually required, but 2 dialysis sessions a week are often not enough, and 3 dialysis sessions a week are usually required. Patients with acute renal failure may need several dialysis sessions to fully or partially recover their renal function without the need for long-term dialysis treatment.
Dialysis is a treatment for end-stage renal failure that does not remove excess water, toxins and small molecules from the body. Through dialysis, the excess water will be discharged from the body to reduce the volume load, and urea nitrogen, plasma potassium, etc. will be discharged from the body to maintain the proper osmolality and electrolyte balance in the body.
For the vast majority of patients with chronic renal failure, dialysis can excrete the water and small molecule toxin substances that the body needs to expel, usually for 4 hours each time, and the doctor will recommend 2 to 3 times a week according to the condition. In case of acute renal failure patients, the renal function may be partially or completely recovered after several dialysis sessions, and there is usually no need for further dialysis treatment at a later stage.
For patients who undergo dialysis 2 times a week, it is recommended to undergo dialysis in hospital regularly, improve relevant examinations as prescribed by doctor, evaluate renal function in time, and adjust treatment plan under doctor’s guidance.
