Analysis of the impact of peritoneal dialysis catheter tail‐end design on catheter‐related complications

Evaluate the impact of peritoneal dialysis catheter (PDC) tail-end design variations on PDC-related complications.Effective data were extracted from databases. The literature was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions, and a meta-analysis was conducted.Analysis revealed that the straight-tailed catheter was superior to the curled-tailed catheter in minimizing catheter displacement and complication-induced catheter removal (RR = 1.73, 95%CI:1.18-2.53, p = 0.005). In terms of complication-induced PDC removal, the straight-tailed catheter was superior to the curled-tailed catheter (RR = 1.55, 95%CI: 1.15-2.08, p = 0.004).Curled-tail design of the catheter increased the risk of catheter displacement and complication-induced catheter removal, whereas the straight-tailed catheter was superior to the curled-tailed catheter in terms of reducing catheter displacement and complication-induced catheter removal. However, the analysis and comparison of factors such as leakage, peritonitis, exit-site infection, and tunnel infection did not reveal a statistically significant difference between the two designs.
