January 2018 CME Article No. 1: Cardiovascular Monitoring During Video Urodynamic Studies in Persons with Spinal Cord Injury
Additional Information
Objective:
The aims of the study were to observe cardiovascular responses during video urodynamic studies and to identify correlations between autonomic dysreflexia events and video urodynamic study findings in spinal cord injuries.

Design:
Thirty-four persons with spinal cord injury were enrolled and investigated using continuous cardiovascular monitoring during video urodynamic studies. Associations between cardiovascular responses and video study variables were analyzed.

Results:
Bladder type–specific cardiovascular responses occurred during the study. The incidence of overactive detrusor during urodynamic study and bladder trabeculation on voiding cystourethrogram was significantly higher in autonomic dysreflexia persons with spinal cord injury (P < 0.05). Systolic blood pressure changes showed moderate negative correlation (r = -0.402, P = 0.020) with bladder compliance and high positive correlation (r = 0.810, P = 0.000) with maximum detrusor pressure. However, no significant differences in neurological level of injury, injury completeness, autonomic dysreflexia symptoms, and voiding type were found. Spinal cord injury increase at each section was significantly higher in overactive detrusor group (P < 0.05). Significant bradycardia or tachycardia correlating with autonomic dysreflexia during urodynamic studies was not observed.

Conclusions: Unpredictable cardiovascular reactions during urodynamic study should be considered carefully in persons with a spinal cord injury above T6.

Learning Objectives:
  1. Describe limitations of previous cardiovascular monitoring during urodynamic study to observe changes in cardiovascular responses
  2. Identify factors contributing to AD during urodynamic testing
  3. Discuss the effect of morphologic features in voiding cystourethrogram including trabeculation and vesicourethral reflux on autonomic dysreflexia.
