  • Title: An investigation of the uncurling forces of indwelling catheters.
    Author: Lowthian PT.
    Journal: Br J Nurs; ; 4(6):328, 330-4. PubMed ID: 7727951.
    Abstract:
    An elastic catheter in the male urethra produces an 'uncurling' force as it attempts to straighten itself. Where this force is sustained, it may result in some pressure necrosis, or pressure atrophy. This article describes how this in-vivo situation was modelled and the resultant pressures checked and recommends the type and size of catheter that should be used if it is needed for more than 2 days of continuous use.
