Summary
Patients with anterior spinal artery syndrome experience urinary retention and altered bladder function, similar to spinal cord injury. However, bladder sensation is preserved, suggesting pathways through the spinal cord's posterior columns.
Area of Science:
- Neurology
- Urology
Background:
- Anterior spinal artery syndrome can impact neurological function, including lower urinary tract control.
- Understanding vesicoureteral dysfunction is crucial for patient management.
Purpose of the Study:
- To investigate lower urinary tract function in patients with anterior spinal artery syndrome.
- To compare vesicoureteral dysfunction in this syndrome to that seen in spinal cord injury.
Main Methods:
- Studied 10 patients with anterior spinal artery syndrome.
- Utilized cystometry and external urethral sphincter electromyography.
- Assessed urinary retention and bladder capacity.
Main Results:
- All patients had acute urinary retention; 9 achieved voiding at a stable stage.
- Reduced bladder capacities were observed in 8 patients.
- Detrusor hyperreflexia and detrusor-sphincter dyssynergia were noted in some patients.
Conclusions:
- Vesicomotor dysfunction in anterior spinal artery syndrome resembles spinal cord injury.
- Preserved bladder sensation suggests posterior column pathways are involved in sensory transmission.
