Summary
Introduction
Knotting during urethral catheterization in children is an unpleasant situation. We
aimed to minimize this risk.
Method
To prevent knot formation, we must understand its nature. We focused on the simplest,
and most fundamental, known as overhand knot.
Results
Calculating the maximum length of catheter inserted in the bladder without risk of
knotting, we estimated the minimum length of catheter needed for an overhand knot.
Discussion
This theoretical approach provides a rough estimation which may contribute to secure
catheterization.
Conclusion
Adding the calculated length to the appropriate for gender and age urethral length,
may reduce knotting risk.
