Abstract
Abstract Background and Aims Peritoneal dialysis (PD) has become a well-established complementary alternative to hemodialysis (HD) as the first-line renal replacement modality. Unlike the temporary catheter for hemodialysis that can be used immediately after implementation, the PD catheter usage period remains controversial. The aim of this study was to compare the short- and long-term outcomes in patients under peritoneal dialysis according to the delay of starting the dialysis after catheter placement. Method This observational prospective study was conducted over an eight-year and four-month period (from April 2014 to August 2021), including all patients treated with peritoneal dialysis for 18 months (from April 2014 to October 2015). The patients were divided into two groups according to whether the catheter was used during the first 15 days (PD-E) or 15 days after (PD-L) catheter placement. The primary outcomes were early complications (mechanical and infectious) within 90 days. Secondary outcomes included technique survival. Results Among the 36 patients included in the study, 14 started PD early (38.8%), while 22 started it 15 days after catheter placement (61.2%). The mean age between the two groups was not significantly different (41 ± 17 years vs 35 ± 16 years, p: not significant). There were no significant differences in the Charlson comorbidity index or the degree of autonomy. The incidence of infections was not significantly different between the two groups (13.6% in PD-L vs 21.4% in PD-E, p: not significant). The total number of mechanical complications was not significantly higher in the PD-E group compared to the PD-L group (42.8% vs 27.3%, respectively, p: not significant). Kaplan-Meier estimates of technique survival were comparable between the groups (log Rank: 1.908, p: 0.67). Conclusion Our study showed no increase in the risk of complications associated with early use of the PD catheter and no difference in technique survival. PD can be used as first-line renal replacement therapy in the unplanned initiation of chronic dialysis.
