What is the primary advantage of using coiled catheters for peritoneal dialysis?

The primary advantage of using coiled catheters for peritoneal dialysis is related to improved patient comfort. Coiled catheters are designed to conform more comfortably to the body’s shape and accommodate the peritoneal cavity, which can lead to a more comfortable experience for patients during dialysis treatments. This comfort can significantly impact a patient's overall adherence to the treatment regimen, as they may feel less discomfort and thus be more willing to continue the therapy.

While factors like kinking, fluid flow, and fibrin buildup are important considerations in the design and function of dialysis catheters, they are secondary to the overall patient experience. Effective hydration and appropriate adjustments in therapy can address issues related to flow and fibrin buildup, but patient comfort directly influences the quality of life and willingness to undergo repeated treatments. Therefore, improved patient comfort is a critical factor in the selection of peritoneal dialysis catheters.
