Abstract
Objective: To investigate the relationship between lesion level and urodynamic findings in spinal cord injury (SCI) patients. Materials and Methods: The medical records of 236 newly injured SCI patients admitted to our inpatient rehabilitation hospital were evaluated retrospectively and 131 patients who had urodynamic evaluation for neurogenic bladder were included in the study. Neurological levels of the patients were compared with the detrusor dysfunction as determined by urodynamic investigation. Results: There were 91 (69.5%) males and 40 (30.5%) females with a mean age of 39.1±15.17 years. The spinal cord lesion was cervical in 31(24%) patients, thoracal in 83 (63%) patients and lumbosacral (13%) in 17 patients. Forty-five percent (45%) of the patients with cervical cord injury, 32% of the patients with thoracal cord injury, and 29% of the patients with lumbosacral cord injury had detrusor hyperactivity. The ratios of low compliance bladders in the cervical, thoracic, and lumbosacral lesions were 58%, 54%, and 64%, respectively. There was no statistically significant relationship between detrusor hyperactivity or compliance and lesion level (p>0.05). According to the The American Spinal Injury Association Impairment Scale (AIS) classification, 83 (63%) patients had a complete lesion and 48 (37%) patients had an incomplete lesion. Hyperactive detrusor was determined in 31% of the patients with complete injury and 42% of the patients with incomplete injury. There were 45 (54%) bladders with low compliance in the complete lesion group and 29 (60%) bladders with low compliance in the incomplete lesion group. No statistically significant relationship was found between detrusor hyperactivity or compliance and AIS grade (p>0.05). Conclusion: We concluded that it not possible to determine the type of neurogenic bladder depending on the level and severity of lesion in SCI patients and urodynamic evaluations are essential for neurogenic bladder management in these patients.
