Participation of pudendal innervation in detrusor overactivity and in overactive bladder syndrome

Abstract

ObjectivesThe functional symptoms of the filling phase and detrusor overactivity are two inter-related dysfunctions of the lower urinary tract. We have aimed to study the participation of the lesion of the pudendal nerve in both urinary dysfunctions. Material and methodsA cross-sectional cutoff study in a series of 108 women was carried out. The study consisted in the questioning on the presence of functional symptoms of the lower urinary tract, cystomanometry and determination of peripheral pudendal nerve latency time, selective electromyography of the external anal sphincter and determination of the sacral reflex latency time. ResultsA tendency was observed toward significance between the presence of pollakiuria amplitude of motor unit potentials (greater in presence of pollakiuria) and the presence of urgency-incontinence and time of sacral latency (greater in the presence of urge incontinence) and a significant relation between the score on the King's Health Questionnaire and peripheral pudendal nerve latency time. Regarding detrusor hyperactivity, greater sacral latency time was observed in patients with overactivity with tendency toward significance. ConclusionsThere is a relation between pudendal innervation alterations and presence of symptoms in the filling phase and detrusor overactivity. This relation would explain the therapeutic action of the perineal rehabilitation on these dysfunctions.
