title: Anorectal Manometric and Urodynamic Parameters According to the Spinal Cord Injury Lesion.
abstract: OBJECTIVE
  To assess the correlation between the anorectal function and bladder detrusor function in patients with complete spinal cord injury (SCI) according to the type of lesion.
  
  
  METHODS
  Medical records of twenty-eight patients with SCI were included in this study. We compared the anorectal manometric and urodynamic (UD) parameters in total subjects. We analyzed the anorectal manometric and UD parameters between the two groups: upper motor neuron (UMN) lesion and lower motor neuron (LMN) lesion. In addition, we reclassified the total subjects into two groups according to the bladder detrusor function: overactive and non-overactive.
  
  
  RESULTS
  In the group with LMN lesion, the mean value of maximal anal squeeze pressure (MSP) was slightly higher than that in the group with UMN lesion, and the ratio of MSP to maximal anal resting pressure (MRP) was statistically significant different between the two groups. In addition, although the mean value of MSP was slightly higher in the group with non-overactive detrusor function, there was no statistical correlation of anorectal manometric parameters between the groups with overactive and non-overactive detrusor function.
  
  
  CONCLUSIONS
  The MSP and the ratio of MSP to MRP were higher in the group with LMN lesion. In this study, we could not identify the correlation between bladder and bowel function in total subjects. We conclude that the results of UD study alone cannot predict the outcome of anorectal manometry in patients with SCI. Therefore, it is recommended to perform assessment of anorectal function with anorectal manometry in patients with SCI.
