Abstract:  Maintenance hemodialysis（MH） is the most important form of renal replacement therapy in patients with end-stage renal disease（ESRD）．Despite many improvements in medical technology have been achieved in recent years，the mortality rate of ESRD patients with MH is still high.In this paper，based on the review of domestic and abroad articles published recently in which the prognosis and associated risk factors in uremic patients with MH were studied，we summarized the predictive factors for poor prognosis in such patients，including older age，prevalence of diabetes mellitus，dyslipidemia and disorders of calcium and phosphate metabolism，poor hypertension management，and so on.In general，there are many risk factors for poor prognosis of uremic patients，which not only involves the disease itself，but also the treatment and follow-up management.
