Simple reinforcement for thin nephrostomy catheters.
OBJECTIVE
Nephrostomy catheters are prone to kinking or damage because the thin, flexible silicone tube is too vulnerable against mechanical stress even when the proximal end is carefully fixed. We developed a simple method to reinforce the outside part of a thin catheter protruding from the skin.


METHODS
We treated 7 children with nephrostomy catheters or ureteral stents with a diameter of 8F or smaller. After insertion a large plastic tube was wrapped around the small catheter, and fixed to the skin and to the peripheral collection system with adhesive tape.


RESULTS
Handling of the catheters improved and there was less need for re-fixation.


CONCLUSIONS
Thin nephrostomy catheters can be effectively protected by wrapping them into a larger, outer tube after insertion.
