Abstract
We report our experience with radical transurethral resection of the prostate performed on 89 male spinal cord injury subjects. The over-all success rate of modified sphincterotomy was 90 per cent, although there was a 14 per cent recurrence rate with time. Urodynamically, success was characterized by a statistically significant reduction in the degree of detrusor-sphincter dyssynergia, an increase in vesical compliance and a reduction in detrusor hyperreflexia. These results suggest an effect on the distal sphincteric area by the adrenergic system in the genesis of detrusor-sphincter dyssynergia. It is suggested that radical transurethral resection of the prostate exerts this effect via a surgical sympathtectomy, while continence is preserved by the activity of the untouched external urethral sphincter.
