Summary

Curled peritoneal dialysis catheters demonstrate good long-term function, with 61% still working at three years. Percutaneous placement is a viable option, showing comparable outcomes to surgical placement for dialysis catheters.

Area of Science:

  • Nephrology
  • Medical Devices
  • Surgical Procedures

Background:

  • Peritoneal dialysis (PD) catheters are crucial for renal replacement therapy.
  • Catheter migration and drainage failure are common complications impacting PD efficacy.
  • Curled catheter design theoretically improves stability and function.

Purpose of the Study:

  • To evaluate the long-term functional outcomes of curled peritoneal dialysis catheters.
  • To compare the efficacy and complication rates of percutaneous versus surgical placement.
  • To assess the incidence of various complications associated with curled PD catheter use.

Main Methods:

  • Retrospective review of 213 curled PD catheter placements over four years.
  • Life-table analysis to determine catheter survival probability.

  • Comparison of outcomes between percutaneous and surgical placement groups.
  • Detailed analysis of complication types and frequencies.

    • Main Results:

    • Catheter survival probability was 88% at 1 year, 71% at 2 years, and 61% at 3 years.
    • No significant difference in function or complication rates between percutaneous and surgical placement.
    • Infectious complications (24/213) and drain failures (9/213) were the most common reasons for catheter loss.
    • Early external dialysate leaking was more frequent with percutaneous placement (21.6% vs. 10.1%).

    Conclusions:

    • Curled peritoneal dialysis catheters offer favorable long-term function and are suitable for percutaneous placement.
    • Percutaneous placement is a safe and effective alternative to surgical placement for curled PD catheters.
    • While early external leakage is more common with percutaneous insertion, it does not lead to catheter loss.
