While urinary catheters are routinely used to provide urinary diversion and manage healing after urethral surgeries and sphincter complications, some experimental evidence suggests that catheterization can induce inflammation and fibrosis, demonstrating that the necessity of catheters for optimal healing remains contested.

The claim specifies that urinary catheters assist in the healing process of the urethral sphincter (or urethra). Several clinical papers (0, 2, 6, 10) support the use of catheters for urinary diversion and to manage healing following urethral trauma or artificial urinary sphincter erosion/explantation. However, experimental studies such as [7] and [8] indicate that catheterization can increase inflammation and fibrosis, and that healing can occur effectively without stents. Therefore, the verdict is CONTESTED due to mixed clinical rationale versus localized inflammatory findings.
