Factors associated with above and under 5-year survival in peritoneal dialysis patients. 
A few patients stay on peritoneal dialysis (PD) for 5 years or longer from initiation of therapy.  We investigated patient survival and factors affecting mortality in PD patients.  This was a retrospective study including 354 PD patients.  The demographic, clinical, and biochemical data were collected from the medical records.  Two hundred patients were excluded.  Evaluation was carried out on data from 154 patients, including 83 surviving 5 years or more and 71 who were taken as surviving less than 5 years.  Mean age, number of comorbid diseases, prevalence of diabetes mellitus (DM), rate of mandatory preference of PD, making their PD exchanges with help from anyone were lower in surviving patients, and education level was higher in surviving patients.  Advanced age, high rate of mandatory preference of PD, high rate of baseline high, and high-average peritoneal transporters were associated with an increased risk of death.  Long-term survival is possible for PD patients, particularly nondiabetics, those having higher education level, those with a self-preference of PD, and those making PD exchanges without any help.
