Purpose:
To present a novel in-vitro pig model for testing the design and function of different internal catheter constructs, along with the resulting exit wound resulting from removal.
Materials And Methods:
We compared the pullout parameters of two nephrostomy catheters that differ only in their internal loop design.
Results:
Greater force, work, and displacement are necessary to extricate catheters with a double loop without increasing exit-wound size.
Conclusion:
Although the differences were not statistically significant, results from this model have potential clinical implications that may prompt further design modifications and prototype development to improve the retention of catheters in the kidney, thus reducing patient discomfort and costs associated with repeated catheter placement.
