The Importance of Residual Renal Function in Peritoneal Dialysis | Biomed Grid

Renal residual function (RRF) is defined like the glomerular filtration rate (GFR) maintained by patients with end-stage renal disease (ESRD) after being included in some dialysis technique [1]. It is difficult to discern which is the best way to calculate it, but it is probably the average of the sum of the urea and creatinine clearance [1]. Throughout this review the most relevant aspects of RRF in peritoneal dialysis (PD) its benefits, its relationship with dialysis adequacy, survival in the technique will be analyzed, concluding with a summary of the most important keys for the preservation of it
