Anorectal Manometric and Urodynamic Parameters According to the Spinal Cord Injury Lesion

This study aimed to assess the correlation between anorectal function and bladder detrusor function in patients with complete spinal cord injury (SCI) according to the type of lesion. Medical records of twenty-eight patients with SCI were included in this study and anorectal manometric and urodynamic (UD) parameters were compared between upper motor neuron (UMN) lesion and lower motor neuron (LMN) lesion groups. The study found that MSP and the ratio of MSP to MRP were higher in the group with LMN lesion, but no correlation was identified between bladder and bowel function in total subjects.

• 1
  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.
• 2
  The ratio of MSP to maximal anal resting pressure (MRP) was statistically significant different between the two groups (UMN vs LMN).
• 3
  No statistical correlation of anorectal manometric parameters was found between the groups with overactive and non-overactive detrusor function.
