Abstract
OBJECTIVE:: Pudendal nerve stimulation (PNS) aims to maximize afferent or efferent stimulation from the sacral plexus. BACKGROUND:: We hypothesized this may be a promising new treatment for patients with bowel dysfunction in complete cauda equina syndrome (CES). METHODS:: Thirteen patients with complete CES [8 constipation predominant (group 1) and 5 incontinence predominant (group 2)] had a 3-week trial of PNS. Patients who showed a 50% or more improvement in symptoms during the trial phase proceeded to permanent neurostimulator implantation. RESULTS:: Five (63%) of the 8 patients in group 1 showed a 50% or more improvement in bowel symptoms during the trial phase and were permanently impla..
