Most patients with suprasacral spinal cord injuries exhibit detrusor hyperreflexia and sphincteric dyssynergia. Unexpected bladder dysfunction suggests a potential sacral cord lesion in spinal cord injury patients.

Area of Science:

  • Neurology
  • Urology

Background:

  • Chronic, stable suprasacral spinal cord injuries (SCI) can impact bladder function.
  • Comprehensive neurological and urodynamic evaluations are crucial for diagnosis.

Purpose of the Study:

  • To characterize urodynamic findings in patients with suprasacral SCI.
  • To identify potential indicators of secondary sacral cord involvement.

Main Methods:

  • 21 patients with chronic, stable suprasacral SCI were evaluated.
  • Neurological assessments and urodynamic studies were performed.
  • Exclusion of secondary lumbosacral lesions.

Main Results:

  • 95% of patients presented with detrusor hyperreflexia and elevated pressures.

  • Sphincteric dyssynergia and a competent bladder neck were common.
  • Areflexia or hypocontractility indicated potential sacral cord dysfunction.

    • Conclusions:

    • Detrusor hyperreflexia with elevated pressures is characteristic of suprasacral SCI.
    • Sphincteric dyssynergia is a frequent urodynamic finding.
    • Unexpected detrusor hypocontractility warrants investigation for sacral cord lesions.
