摘要

Most studies reportthat residual renalfunction (RRF) is maintained Longer on peritoneal dialysis (PD) than on hemodialysis (1). Residual renalfunction is a predictive factor of survival of patients on PD (2), and its preservation must therefore be a priority in dialysis patients.During dialysis, there is a progressive loss of RRF, but the progression of loss on PD is slower compared to pre-dialysis periods (3). In fact, some patients on PD maintain their RRF as at the beginning of treatment for some time, and some even recover it, requiring abandonment of the treatment (4). The factors involved have not been fully determined.The main aim of this study is to analyze the evolution of RRF at the first year of treatment with PD, seeking to determine the percentage of patients that maintain or increase their RRF and what factors may be involved.
