Summary
A novel endoscopic balloon dilation effectively treated external urethral sphincter spasticity in a multiple sclerosis patient. This procedure eased catheterization difficulties and normalized urethral pressure for at least seven months.
Area of Science:
- Urology
- Neurology
- Medical Device Technology
Background:
- External urethral sphincter spasticity can impede bladder management, particularly in patients with neurological conditions like multiple sclerosis.
- Intermittent catheterization is a common management strategy, but sphincter spasticity can render it impossible.
- A minimally invasive endoscopic approach for sphincter spasticity is needed.
Observation:
- A patient with multiple sclerosis experienced severe external urethral sphincter spasticity, preventing intermittent catheterization.
- Endoscopic balloon dilation of the external urethral sphincter was performed using a 25mm balloon catheter.
- The procedure aimed to reduce sphincter resistance and improve catheter passage.
Findings:
- Following balloon dilation, resistance to catheterization resolved completely.
- Urethral pressure profilometry demonstrated a significant reduction in sphincteric pressure post-procedure.
- The achieved reduction in sphincteric pressure was maintained at a normal level for at least seven months.
Implications:
- Endoscopic balloon dilation presents a simple, effective treatment for external urethral sphincter spasticity.
- This minimally invasive technique offers a potential solution for bladder management challenges in neurological patients.
- Sustained efficacy suggests long-term benefits for patients requiring intermittent catheterization.
