Bladder dysfunctions are often observed in patients with multiple sclerosis (MS). In order to evaluate their sensitivity in detecting abnormalities in bladder central control pathways, pudendal nerve somatosensory evoked potentials (pSEPs) were recorded in 16 patients with clinically probable MS: six were affected by retention or urge incontinence, and ten were asymptomatic. Conventional visual, auditory and somatosensory evoked potentials were also recorded, and all of the patients underwent a urodynamic examination. Prolonged latency or the absence of pSEP cortical responses was found in eight of the ten asymptomatic patients, and in all of the symptomatic cases (87.5%). The urodynamic evaluation revealed abnormalities in 12 patients (75%). Our findings seem to indicate an early and frequent involvement of bladder control pathways in MS patients, as well as a high rate of subclinical disorders.

Abstract

Bladder dysfunctions are often observed in patients with multiple sclerosis (MS). In order to evaluate their sensitivity in detecting abnormalities in bladder central control pathways, pudendal nerve somatosensory evoked potentials (pSEPs) were recorded in 16 patients with clinically probable MS: six were affected by retention or urge incontinence, and ten were asymptomatic. Conventional visual, auditory and somatosensory evoked potentials were also recorded, and all of the patients underwent a urodynamic examination. Prolonged latency or the absence of pSEP cortical responses was found in eight of the ten asymptomatic patients, and in all of the symptomatic cases (87.5%). The urodynamic evaluation revealed abnormalities in 12 patients (75%). Our findings seem to indicate an early and frequent involvement of bladder control pathways in MS patients, as well as a high rate of subclinical disorders.
