ABSTRACT
Purpose
To investigate the video-urodynamic and pelvic floor electrophysiological characteristics in patients with traumatic spinal cord injury.
Methods
This retrospective reviewed the clinical records, urodynamic and pelvic floor electrophysiological data of 647 patients with traumatic spinal cord injury (SCI) and out of spinal shock. Patients were classified based on American Spinal Injury Association (ASIA) Impairment Scale and urodynamic findings.
Results
Of the 647 patients, detrusor overactivity (DO) with or without detrusor sphincter dyssynergia (DSD) was found in 79.5%, 61%, 35.2%, 35%, and 19.2% of patients with cervical, thoracic (T1-9), thoracic (T10-12), lumbar, and conical cauda injury, respectively. Other patients manifested detrusor areflexia (DA). Patients with DO and/or DSD had a longer duration of SCI at each injury level than patients with DA. In suprasacral injury patients with DA, 63.0% (58/92) had a normal bulbocavernosus reflex (BCR) response. Compared with patients without bladder sensation, bladder capacity during urine leakage was far higher in those with bladder sensation. The manifestation of BCR and somatosensory-evoked potential (SEP) was associated with the level of injury.
Conclusions
This study showed a significant correlation between the level of SCI and video-urodynamic findings, but clinical examination cannot by predict bladder function; urodynamic testing is also necessary. In addition, the role of BCR and SEP for guiding bladder management is limited. Moreover, bladder sensation is important for urinary control in patients with traumatic SCI.
