Objective: The main objective of the study was to analyse the progression of residual renal function according to the dialysis technique (peritoneal dialysis or haemodialysis) and the frequency of treatment (two or three sessions of haemodialysis per week). As secondary objectives, we studied the progression of the serum concentration levels of β2 microglobulin and the response of anaemia to erythropoietic agents.
Material And Method: 193 non-anuric patients were included and began renal replacement therapy with dialysis in our hospital between 1 January 2006 and 31 December 2011, with a follow-up period of over three months.
Introduction: In contrast to patients treated with peritoneal dialysis, those on periodical haemodialysis (HD) do not receive programmed progressive increases in dialysis dosage, nor is residual renal function taken into account in the calculation of the total dialysis prescription; rather, only dialyser clearance is factored into the equation. In 2006, we decided to establish a progressively increasing dialysis regimen at the start of renal replacement therapy, evaluating the possibility of starting with 2 sessions of HD/week when renal clearance of urea was equal to or greater than 2.5 ml/min.
