Analysis of outcome and factors correlated with maintenance peritoneal dialysis

Abstract

Objectives This study aimed to analyze the outcome and factors correlated with maintenance peritoneal dialysis (PD) to provide guidance for improving prognosis, and prolonging the catheterization and survival times of patients on PD with end-stage renal disease. Methods Clinical data of patients at The Third Xiangya Hospital of Central South University were retrospectively analyzed. We compared the survival and technique survival rates of patients, and analyzed relevant factors. Results A total of 510 cases of PD were included. Two hundred thirty-nine patients continued to receive PD treatment, 73 received kidney transplants, 72 transferred to hemodialysis, and 126 died. The main reasons of death were cardiovascular (27.00%) and cerebrovascular diseases (23.80%). The main reasons of transfer to HD were peritonitis and inadequate dialysis. The survival rates at 1, 2, 3, 5, and 7 years were 95.75%, 90.34%, 82.35%, 66.21%, and 54.32%, respectively. The technique survival rates at 1, 2, 3, 5, and 7 years were 93.22%, 86.76%, 77.91%, 63.16%, and 47.67%, respectively. Female sex and older age were protective factors that affected patients’ withdrawal from PD and survival time. Conclusions Death is the primary reason for withdrawal from PD. Female sex and older age affect patients’ withdrawal from PD and survival.
