Improved voiding in response to electrical stimulation of the spinal cord of paraplegic dogs

Bipolar electrodes were inserted into the conus medullaris and attached to the proximal urethra of paraplegic dogs. Repeated stimulus trains were delivered to the spinal cord electrodes and the urethral electrodes in an attempt to improve voiding induced by cord stimulation. The results indicate that the increased outflow resistance which often accompanies electromicturition can be significantly overcome both by repeated spinal cord stimulation and by prestimulation of the proximal urethra.
