Research summary
This study focuses on the examination and analysis of intermittent catheters after use. Urethral trauma is damage caused to the urethra, often by force, and can cause pain, discomfort, inflammation and bleeding. The repetitive use of intermittent catheters has been associated with urethral trauma. Friction between the surface of the catheter and the urethral tissue on insertion and removal of the catheter from the bladder can cause pain, discomfort, bleeding and damage. Some intermittent catheter products have outer coatings which provide lubrication to reduce friction and pain experienced on insertion. However, these outer coatings on the catheters can become ‘sticky’ and can detach from the surface during removal of the intermittent catheter from the bladder.
We aim to collect used intermittent catheters from participants. These intermittent catheter samples will be analysed for evidence of urethral trauma. Specifically, the surface of the catheters will be observed using microscopy techniques to detect evidence of catheter coating removal and urethral cells sticking to the catheter. Staining of the catheter surface will also be used to detect the presence or absence of blood.
The research will provide both an understanding and observation of urethral trauma caused by intermittent catheters. We hope that this study may help improve future development and the use of intermittent catheters in order to minimize the effect of urethral trauma and discomfort for people using these devices.REC name
