A Finetech-Brindley bladder controller was implanted in 17 patients with a complete lesion of the spinal cord. During a microscopic procedure in the cauda equina, the sacral roots were identified and the posterior components of the S2, S3 and S4 roots were cut. The stimulator was placed intradurally around the anterior components of the S2, S3, S4 roots and the S5 root. Our patients have now been followed-up for periods varying between 1 and 6 years. In all 17 patients, the bladder capacity has been increased; 16 patients have a residual volume of less than 30 ml, urinary tract infection is rare; 12 patients are fully continent. All male patients can achieve a full sustained erection by means of the implant and 13 patients are using the implant for bowel function. The method has no significant harmful effects or complications.

“…The spinal cord mictu rition center [8,9], the detrusor itself [1,[10][11][12], the pel vic nerve and the sacral root nerves [3,4,6,7] have been regarded as possible sites for electrical stimulation. Al though the sacral nerve root stimulation has several advantages [13,14], specific stimulation of bladder motor neurons is impossible in the sacral roots' stimulation, since the motor neurons of the urethral sphincter are located within the same sacral cord and extend their axons through the sacral roots.…”

“…High-frequency stimulus over 300 Hz reduced elevated urethral clo sure pressure, which was induced by tetanic stimulus, up to 30-45%. type voiding [2,4,6,7] or voiding by high-frequency stim ulus [5,[13][14][15], However, reduction of the urethral pres sure by the pudendal neurectomy and/or selective section ing of somatic fibers seemed inevitable to achieve suffi cient voiding [3].Reversible nerve conduction block by high-frequency stimulus has been available in the control of the muscle contraction [16,17], It was found that tetanic muscle con traction evoked by electrical stimulation can be blocked by high-frequency electrical stimulation. If such a method can be applied to the control of external urethral sphincter mechanism, urethral pressure during tetanic contraction may be modulated by this technique.…”
