High creatinine levels do not necessarily indicate uremia, but during uremia, creatinine levels will certainly increase. Clinically, we consider creatinine levels above 707 as uremia. Once uremia is diagnosed, treatment mainly involves renal replacement therapy or transplantation. Renal replacement therapy mainly includes hemodialysis and peritoneal dialysis, each with its own advantages and disadvantages, and the choice should be based on the patient's individual condition. Renal transplantation is currently the best treatment option, which can be done through relatives or donations. After a kidney transplant, one can live and work like a normal person, but long-term oral immunosuppressive medication is required.
