Summary
Detrusor-urethral sphincter dyssynergia, a bladder voiding disorder, involves sphincter dysfunction during bladder contraction. Spinal cord injury severity correlates with the degree of this micturitional disorder.
Area of Science:
- Urology
- Neuroscience
- Physiology
Background:
- Detrusor-urethral sphincter dyssynergia is a complex micturitional disorder characterized by abnormal urethral sphincter function during bladder contraction.
- This condition significantly impacts bladder emptying and can be associated with neurological injuries.
Purpose of the Study:
- To classify and describe grades of detrusor-urethral sphincter dyssynergia.
- To investigate the relationship between spinal cord injury characteristics and the degree of dyssynergia.
- To review the pathophysiology and management strategies for this condition.
Main Methods:
- Clinical experience with over 200 spinal cord injury patients.
- Serial urodynamic observations to assess bladder and sphincter function.
- Classification of dyssynergia into grades 1 to 3 based on clinical and urodynamic findings.
Main Results:
- Various grades (1-3) of detrusor-urethral sphincter dyssynergia were identified.
- The duration and completeness of suprasacral spinal cord injury were key determinants of dyssynergia severity.
- Internal sphincter dyssynergia was observed less frequently in the studied population.
Conclusions:
- Spinal cord injury significantly influences the development and severity of detrusor-urethral sphincter dyssynergia.
- Urodynamic assessment is crucial for diagnosing and grading this micturitional dysfunction.
- Understanding the pathophysiology is essential for effective management of detrusor-urethral sphincter dyssynergia.
