PURPOSE: 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. MATERIALS AND 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.
