Abstract: Residual renal function (RRF) is closely associated with increased survival in dialysis patients. Avoiding the factors aggravating renal injury is the main strategy to protect RRF of dialysis patients. With the continuous extension of dialysis duration，more patients are involved in vascular interventional examination and treatment. The application of iodine contrast media (ICM) may lead to acute kidney injury (AKI). However, how does ICM affect the RRF of dialysis patients? This paper reviews the research progress of the effect of ICM on RRF in dialysis patients.
