Abstract
A new method of stimulating the sacral and coccygeal roots was used to induce voiding in spinal dogs. The method consisted of inserting platinum stimulating electrodes through drilled holes in the dorsal surface of sacrum into the sacral canal in the vicinity of the spinal roots. Stimulation with this method was previously shown effective in inducing strong detrusor contraction and in completely emptying the bladder in anesthetized spinal dogs. In the present study, stimulation with this method was effective in completely emptying the bladder in both male and female conscious spinal dogs. This method appears to be safe as the two long‐termed spinal dogs were maintained healthy by emptying the bladder twice daily, the male for more than two years and the female for more than three years, until they were killed at the conclusion of the project. Unlike the conventional method, the electrodes in this method are replaceable. The safety and electrode replaceability of this method makes its future clinical use very attractive. The maximum urine output following a single stimulation increased several folds from an initial volume of 20 to 25 ml in three to four weeks.
