Abstract

This study was designed to find the association between the injury level and changes in bladder function. This was a descriptive cross sectional study performed on 30 patient of spinal cord injury. Categorization of patients was done based on clinical neurologic level and completeness and incompleteness of spinal cord injury (SCI) according to American Spinal Injury Association Classification (ASIA). Urodynamic study (UDS) was done on Laborie Dorado KT concept machine in Department of Physical Medicine and Rehabilitation. Reduced bladder compliance in 100% cases of cervical SCI and lumbar levels SCI and 27.85% of thoracic level SCI. Detrusor overactivity was found in 2 cases of cervical level, 10 cases of thoracic level and 1 case of lumbar level. Detrusor-external sphincter dyssynergia (DESD) in 100% patients of cervical, 77.8% patients of thoracic and 40% patients of lumbar level injuries. Detrusor areflexia was found in the 10% patients of the lumbar neurological level and absent in the cervical and thoracic level of injury. Normal PVRU was founded in 100% cases of thoracic and 10% of lumbar level. Bladder capacity was more affected in lumbar SCI than thoracic SCI. Detrusor over activity and bladder capacity significantly related with completeness and regional neurological level of injury. This association is not founded with all the parameter of urodynamic. Thus we can conclude that there is no significant association between neurological injury level and urodynamic parameter.
