PDkateter
PDkateter, or peritoneal dialysis catheter, is a surgically implanted conduit that provides access to the peritoneal cavity for the exchange of dialysis fluid in peritoneal dialysis. It enables continuous or intermittent infusion and drainage of dialysate, allowing patients to perform dialysis at home or in other non-hospital settings. The most common type is the Tenckhoff catheter, designed with a flexible silicone or polyurethane tube, a curled or straight intraperitoneal tip, and a subcutaneous tunnel with one or two Dacron cuffs to reduce infection risk and stabilize the catheter.
Design features include an external, skin-facing segment for the exit site and a subcutaneous tunnel that helps
PDkateter is used to conduct both continuous ambulatory peritoneal dialysis (CAPD) and automated PD (APD). After
Complications can include peritonitis, exit-site or tunnel infections, dialysate leaks, catheter obstruction or migration, and hernia.
The lifespan of a PDkateter varies but is often years, depending on infection control, mechanical function,
