Mucosal injuries from indwelling catheters: A scoping review

Area of Science:

• Urology
• Medical Device Research
• Patient Safety

Background:

• Limited understanding of bladder mucosa injuries associated with modern indwelling urinary catheters.
• Need for comprehensive data on injury types and frequency in adult patients.

Purpose of the Study:

• To identify and present existing information on bladder mucosa injuries in adult patients using indwelling urinary catheters.
• To address the research question: What is known about mucosa injuries in urine bladders among patients with indwelling urinary catheters?

Main Methods:

• Scoping review utilizing the patient, exposure, and outcome framework.
• Systematic search across five databases, following PRISMA guidelines.
• Inclusion of eight studies from three countries using diverse data collection methods.

Main Results:

• Mucosa injuries, including polypoid cystitis, were reported in all included studies (41%-100%).
• Injured areas ranged from 0.5 to 2.5 cm, predominantly on the posterior bladder wall.
• Eleven distinct injury concepts were identified across the studies.

Conclusions:

• Significant knowledge gaps exist regarding bladder mucosal injuries in patients with indwelling urinary catheters.
• Further research is crucial to enhance understanding and improve clinical outcomes.
• A robust scientific foundation is lacking regarding the impact of urinary catheters on bladder mucosa.
