Abstract

STUDY DESIGN:

Retrospective chart review.

OBJECTIVES:

To establish the frequency and severity of autonomic dysreflexia (AD) during urodynamics among individuals with chronic spinal cord injury (SCI) and to investigate the possible effect of the number of years since SCI on the severity of AD.

SETTING:

SCI outpatient clinic.

METHODS:

A retrospective chart review was undertaken of individuals with SCI who were seen at an outpatient clinic and could potentially develop an episode of AD (T6 and above). Data regarding age, gender, urodynamic examination, lower urinary tract function, cardiovascular parameters and SCI were collected. In addition, information on signs and symptoms of AD were retrieved.

RESULTS:

A total of 76 individuals with SCI were examined with blood pressure (BP) monitoring. The majority had cervical SCI (79%). The mean age was 47.8±13.9 years. The median duration after SCI was 51.5 months. During urodynamics, a total of 48 (63.2%) individuals showed an increase in systolic BP>20 mm Hg, meeting the criteria for AD. Indicators for higher incidences of AD were cervical SCI, being >2 years after SCI, the presence of detrusor sphincter dyssynergia (DSD) and low bladder compliance. AD was more severe in individuals with complete (American Spinal Cord Association (ASIA) impairment scale (AIS) A) injuries, worse with greater time after SCI.

CONCLUSION:

Individuals with cervical SCI, DSD, poor bladder compliance or >2 years after SCI were associated with a higher possibility of developing AD during urodynamics. Furthermore, AD was more severe in complete (AIS A) individuals and was exacerbated with time after injury.
