Abstract
The intraspinal extradural segments of the sacral nerves were stimulated [in dogs] in an effort to obtain the combination of maximal detrusor contraction and minimal outflow resistance essential for effective micturition. Each root was stimulated unilaterally and bilaterally. Each was separated into its motor and sensory components and these components were then individually stimulated. The most effective result was obtained with stimulation of root S[sacral]2. As in the experimental animal, sacral roots in the human have a long intraspinal course that makes them accessible for implantation of electrodes. A chronically implantable sacral root electrode is being studied, providing a tool for efficient emptying of the denervated bladder.
