Official Title

Determining the Most Appropriate Time to Evaluate Detrusor Activity Recovery in Acute Traumatic Spinal Cord Injuries

Brief Summary

      Determining the most appropriate time to evaluate detrusor activity in urodynamic studies for
      both traumatic and non-traumatic spinal cord injuries

Detailed Description

      The detrusor activity in the acute phase of the spinal cord injury changes with the
      development of the spinal shock. Spinal shock is a phase of areflexic phase after the spinal
      cord injury that is primarily influenced by the severity of the injury and the neurological
      level of injury. Detrusor activity shows areflexic in the spinal shock phase, followed by a
      return of detrusor activity at the end of the spinal shock.

      There was no recent study to provide evidence of an appropriate time to assess detrusor
      muscle activity through urodynamic studies. There were only a few limited studies on detrusor
      activity following spinal cord injury from 1960 to 1970. However, when the urodynamic study
      should be performed is still controversial.

      Knowing the patterns of detrusor activity following spinal cord injuries is critical to
      determining the appropriate timing for intermittent catheterization, which is the standard
      emptying method of choice. If clinicians fail to understand true detrusor activity as early
      as possible, the patient will suffer from unnecessary indwelling catheter voiding, resulting
      in impaired quality of life in the acute phase.
