Complications like stent migration and recurrent stenosis occurred in men receiving the UroLume stent for urethral stricture or spinal cord injury. Careful patient selection is crucial, as removal can be complex.

Area of Science:

  • Urology
  • Medical Devices
  • Reconstructive Surgery

Background:

  • The UroLume endoprosthesis has been used since 1990 for urethral stricture disease and detrusor-sphincter dyssynergia in spinal cord injury patients.
  • Despite reported success, complex cases present management challenges.

Purpose of the Study:

  • To evaluate the outcomes and complications associated with UroLume endoprosthesis placement in a cohort of patients.
  • To identify potential issues and areas for improvement in patient selection and management.

Main Methods:

  • Retrospective analysis of 10 male patients who underwent UroLume stent placement.
  • Review of complications, additional procedures, and outcomes following stent insertion.

Main Results:

  • Four patients with detrusor-sphincter dyssynergia experienced stent migration and required further interventions.
  • Six patients with urethral stricture disease had recurrent stenosis within or adjacent to the stent, necessitating repeat procedures.
  • Complications included urosepsis, retention, bleeding, and the need for stent explantation.

Conclusions:

  • Stent migration and recurrent stenosis are significant concerns following UroLume insertion.
  • Tandem stent placement may lead to urethral obstruction.
  • Improper patient selection is a likely cause of adverse outcomes, emphasizing the need for judicious use and careful case selection.
