    Abstract:
    INTRODUCTION: Various innovations for preventing complications and improving a patient's quality of life have been implemented for peritoneal dialysis (PD), which was established in Japan approximately 35 years ago and introduced at our hospital in 1999. Herein, we investigate the outcomes of patients undergoing PD to identify approaches for improving their long-term prognosis. METHODS: This retrospective study included 114 patients who underwent PD between September 1999 and August 2017 and included various parameters such as patient survival rate, technical survival rate, cause (s) of PD withdrawal, incidence of peritonitis, dialysis duration, and change in residual renal function (RRF). Furthermore, factors associated with PD withdrawal and duration, as well as risk factors for peritonitis, were examined. RESULTS: Mean (± standard deviation) PD duration was 35.62 (±29.88) months in all patients and 37.16 (±34.09) months in 58 patients who withdrew from treatment. Five-year continuance and survival rates were 40.41% and 55.74%, respectively (p=0.0061). However, in patients aged ≥65 years, the continuance and survival rates were not significantly different (p=0.1250). Furthermore, the continuance and survival rates in diabetic patients were not significantly different from those of non-diabetic patients (p=0.1334 and 0.7140, respectively). Comparison of changes in RRF in young and elderly patients revealed that it was not significantly sustained in elderly patients (p=0.0259). The Cox proportional hazards model revealed that age (p=0.0455) and total cholesterol levels (p=0.0494) were independent risk factors for PD withdrawal, and multiple regression analysis showed that the presence of peritonitis (p=0.0063) and low-density lipoprotein cholesterol (LDL-C) levels (p=0.0087) were significant factors for PD duration. Peritonitis incidence was 0.077 times per patient per year, and multivariate analysis identified PD duration (p=0.0009) and LDL-C levels (p=0.0054) as independent risk factors for peritonitis. CONCLUSION: The findings of this study revealed that assessment of the nutritional status of the patient and prevention of peritonitis are important for continuation of PD. PD is a safe treatment option that can maintain the quality of life in elderly patients. In a rapidly aging society, the need for PD-based medical care is expected to increase.
