Whether dialysis is needed for high creatinine depends mainly on the cause and level of creatinine elevation and whether there are complications. If the creatinine is elevated due to physiological reasons, or the creatinine level has not reached the end-stage renal disease and there is no obvious complication, usually dialysis is not needed; if the creatinine level has reached the stage of uremia, or there are complications such as hyperkalemia and acute left heart failure which can not be corrected by drugs, then dialysis is needed. Part of creatinine elevation may be due to the patient’s own muscle content is higher, or usually eat more meat caused by more exercise, if the urine routine and urinary system ultrasound and other related tests are not abnormal, clear kidney without obvious diseases, improve the habits of creatinine may return to normal, this time does not need dialysis. Some chronic kidney diseases such as chronic nephritis, creatinine level may increase, but not reach the level of uremia, and there is no hyperkalemia, acute left heart failure and other complications, to be active treatment of the primary disease, to slow down the progress of renal function can be, at this time do not need dialysis treatment. When creatinine rises gradually and reaches the uremia stage, or there are complications such as hyperkalemia and acute left heart failure which cannot be corrected by drugs, dialysis treatment is needed at this time. Patients with acute kidney injury with oliguria and anuria or serious complications also need dialysis treatment. Patients with high creatinine are recommended to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
