The present study demonstrates a strong predictive value of daily peritoneal UF for both technique and patient survival in prevalent anuric PD patients. In multivariate Cox regression analysis, age, time-dependent UF volume and serum albumin were independent predictors of mortality, while UF independently predicted technique failure.Ĭonclusions. Using Kaplan–Meier analysis, patients with baseline UF <1 L/24 h had significantly worse outcome (survival, 27.2 ± 3.9 vs 42.4 ± 1.9 months P < 0.001). Also, while Kt/V and CCr were stable over time, UF decreased significantly over the study period (baseline, 1205.5 ± 327.3 ml/24 h vs after 3 years, 870.6 ± 439.8 ml/24 h P < 0.001). When compared to those with a UF <1 L/24 h, patients with a UF ≥1 L/24 h had significantly higher haemoglobin levels (101.9 ± 20.5 vs 89.3 ± 20.2 g/L, P < 0.05) and tended to be younger (55.0 ± 12.5 vs 60.6 ± 16.1 years, P = 0.10). Kaplan–Meier analysis and Cox proportional hazards models were used to identify risk factors of mortality and technique failure in patients with a UF ≥1 L/24 h or <1 L/24 h. Clinical and PD parameters were recorded yearly.

We retrospectively analysed a cohort of 86 prevalent anuric PD patients followed up for a median of 25.3 months (range, 6 to 54 months). The optimal ultrafiltration (UF) volume in patients on peritoneal dialysis (PD) remains controversial. Maintenance dialysis therapy is the only way to remove excess fluid in patients with anuric end-stage renal disease.
