    Abstract:
    Neurostimulation to restore the essential elements of lower urinary tract function is a very promising approach in the management of the neuropathic bladder. The goal of neurostimulation is to restore the three main functions of the lower urinary tract: the reservior capacity of the bladder, the sphincteric activity of the continence mechanism, and the ability of the bladder to evacuate completely. In extensive experimental studies conducted over the past 18 years, the physiological foundations of micturition and sphincteric control were investigated, which made the clinical application of neurostimulation in the management of the neurogenic bladder possible. In human studies, the essential experimental model of ventral root stimulation after dorsal rhizotomy and selective peripheral neurotomy proved to be the most successful. To date, over 220 patients have been treated, of whom 35 have spinal cord injury or severe neuropathy and received multiple sacral root implants. 25 of the 35 patients are evaluable, 15 (60%) of these achieved the three goals of the study: complete continence, restoration of reservoir function with adequate capacity, and voiding to neurostimulation with minimal residual urine or none. The remaining 185 patients with a variety of voiding dysfunctions classified under four main headings: 1) urge incontinence; 2) post-prostatectomy incontinence; 3) pelvic dysfunction syndrome in the male; 4) pelvic dysfunction syndrome in the female were treated by single electrode implantation in order to modulate spastic voiding dysfunction and pelvic floor activity. Success rates (improvement of 50% or more) were 72%, 38%, 46%, and 47% in the four groups, respectively.
