The impact of catheter design on preventing CAPD complications.
Continuous ambulatory peritoneal dialysis has become a practical and safe mode of therapy for patients with end-stage renal disease. The creation of a durable, safe and efficient peritoneal access has been made possible through refinements in catheter design. The Tenckhoff catheter and its modifications has remained the most popular peritoneal access devise over the last 25 years. The major objectives' in catheter design include ensuring biocompatibility, ease with which the catheter can be implanted and removed as well as esthetic appeal. The other features in a peritoneal dialysis catheter are those that reduce catheter related complications such as catheter migration, exit-site and tunnel infections, flow restriction and catheter cuff erosion. Although the perfect peritoneal catheter remains elusive as yet, refinements in design and manufacturing materials have facilitated the implantation and maintenance of the catheter resulting in better dialysis technique survival, lesser morbidity and greater patient acceptance.
