Patients with kidney failure who remain anuric after dialysis need to continue hemodialysis treatment. Hemodialysis for kidney failure patients is a kind of renal replacement therapy. Acute renal failure patients with no urine after dialysis may be the kidney function has not recovered, can continue hemodialysis treatment, and observe the patient’s urine output, if continue to have no urine, then the kidney damage may be irreversible, need regular hemodialysis treatment. With the prolongation of dialysis treatment time, patients with chronic renal failure have a gradual decrease in urine output, or even anuria, which is due to long-term dialysis, increased ultrafiltration, hemodynamic changes, and further damage to residual renal function, resulting in anuria. At this time, attention should be paid to the control of water intake and diet, and timely adjustment of the dialysis program to remove toxins, improve the water electrolyte acid-base imbalance, etc.. Anuria after dialysis in renal failure patients should be analyzed according to specific conditions and treated under the guidance of doctors, and regular hemodialysis treatment if necessary.
