title: [Factors related to residual renal function loss in patients in peritoneal dialysis].
abstract: BACKGROUND
  Residual renal function (RRF) contributes to the quality of life of patients on dialysis. The preservation of RRF is associated with higher patient survival in peritoneal dialysis (PD), and is now accepted that RRF and peritoneal clearance are not of equal value in patient survival. The aim of this study is to know the factors related to RRF loss in prevalent patients in continuous ambulatory peritoneal dialysis (CAPD).
  
  
  METHODS
  This is an analysis of secondary outcomes. Forty-three adult patients with type 2 diabetes were included. They had RRF preserved. Clinical and laboratory assessments were done in each visit during a year.
  
  
  RESULTS
  The male gender (p = 0.042), systolic (p = 0.009) and diastolic (p = 0.006) blood pressure (BP), hemoglobin (p = 0.008), peritoneal creatinine clearance (p = 0.014), peritoneal ultrafiltration (p = 0.017) and levels of tumor necrosis factor-alpha (TNF-alpha) in plasma (p = 0.022) and dialysate (p = 0.008) were related with RRF loss.
  
  
  CONCLUSIONS
  It is important to understand the factors associated with RRF loss in our patients to prevent the gradual loss and its implications on the mortality and quality of life.
