Abstract

Electrical stimulation of sacral roots for electromicturition results in simultaneous activation of bladder and external urethral sphincter. The sphincter contraction hinders bladder emptying. Here, anodal blocking is described as a means to reduce the activation of the urethral sphincter. Using a tripolar electrode configuration and monophasic rectangular current pulses in acute canine experiments, a reduction of intraurethral pressure response, as compared to stimulation without blocking, of more than 80% could be achieved in all experiments
