Peritoneal dialysis catheter

Last revised by Arlene Campos on 21 May 2024

A peritoneal dialysis catheter is a flexible tube designed for peritoneal dialysis, the most well-known and widely-used being the Tenckhoff catheter

From an MRI perspective, the Tenckhoff catheter has an extraperitoneal tungsten tip which is MRI-compatible, however, it will cause some susceptibility artefacts if the tip is overlying the area being imaged.

History and etymology

In 1968 an American nephrologist Henry A Tenckhoff (d.2017) 2 introduced his eponymous peritoneal indwelling catheter 1

The major improvements made by Dr Tenckhoff over the Palmer-Quinton catheter, the main one in use at the time, was:

  • using the recently discovered inert and flexible Silastic as the catheter material

  • the addition of Dacron cuffs near the ends to improve skin anchorage and decrease secondary infection rates

  • developing and patenting an insertion trocar
