Different forms of dysfunction of the lower urinary tract can be treat
ed with electrical stimulation. Currently, two operative treatment mod
alities are available. In patients with spinal cord injury the combina
tion of posterior sacral root rhizotomies with implantation of electro
des on the anterior roots produces excellent results in terms of resto
ration of continence and bladder evacuation. In patients with chronic
problems of urge incontinence, urgency/frequency and voiding dysfuncti
on, neuromodulation of a sacral nerve with an implantable system can r
educe the symptomatology significantly. Both these treatments are a va
luable addition to the modern neuro-urological practice.
