Residual renal function (RRF) remains important even after beginning of dialysis. RRF contributes significantly to the overall health and well-being of patients on dialysis. ⋯ More importantly, the loss of RRF is a powerful predictor of mortality. This article will review the evidence supporting the importance of RRF on outcome and outline potential strategies that may better preserve RRF in patients on dialysis.
