Insights
A simple technique reinforces thin nephrostomy catheters by wrapping them in a larger tube, reducing mechanical stress and improving handling. This method enhances the durability of nephrostomy tubes and ureteral stents.
Area of Science:
- Urology
- Medical Devices
- Nephrology
Background:
- Nephrostomy catheters are susceptible to kinking and damage due to mechanical stress.
- The thin, flexible silicone material of these catheters offers limited protection.
Purpose of the Study:
- To develop a simple method for reinforcing the external portion of thin nephrostomy catheters.
- To enhance the mechanical resilience of nephrostomy tubes and ureteral stents.
Main Methods:
- A reinforcing large plastic tube was wrapped around the protruding part of the nephrostomy catheter or ureteral stent.
- The outer tube was secured to the skin and collection system using adhesive tape.
- The technique was applied to 7 pediatric patients with catheters or stents of 8F diameter or smaller.
Main Results:
- Improved handling of the nephrostomy catheters was observed.
- The need for frequent re-fixation of the catheters was reduced.
- The external reinforcement effectively protected the thin silicone tubes.
Conclusions:
- Wrapping thin nephrostomy catheters in a larger outer tube is an effective method for protection.
- This technique enhances the durability and usability of nephrostomy catheters and ureteral stents.
- The described method offers a simple solution to prevent mechanical damage to indwelling urinary drainage tubes.
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.
