Abstract: A well-functioning peritoneal dialysis catheter (PDC) is a critical prerequisite for successful peritoneal dialysis (PD) therapy. There is no consensus about the best method for PDC placement. Ultrasound-guided Seldinger percutaneous puncture PD placement is now a well-established technology. However PD can still be terminated due to technical or infectious reasons such as catheter migration, leakage, and peritonitis. Therefore, continuous improvement of catheter placement techniques to increase catheter technical survival is an urgent issue to be solved. This article focuses on the improvement of operation procedures and the advantages of Seldinger percutaneous PDC placement.
