Relationship between neurological and urological status in patients with multiple sclerosis

The relationship between neurological urinary symptoms and urodynamic findings in patients with multiple sclerosis was examined. The duration of multiple sclerosis was significantly longer in patients with urinary symptoms. The presence of urinary symptoms correlated with the severity of the pyramidal or sensory lesions and the total disability score. Cystometrograms revealed detrusor hyperreflexia in 67 per cent of the patients, areflexia in 21 per cent and a normal detrusor in 12 per cent. Somatic dyssynergia was found in 20 of the 39 patients whose examination revealed clear-cut results. Positive correlation was found between urge incontinence and detrusor hyperreflexia, and between hesitancy and detrusor areflexia but no relationship was found between urological symptoms and sphincter function. Analysis of the neurological lesions in relation to the cystometric findings revealed a positive correlation among pyramidal lesions, detrusor hyperreflexia and detrusor areflexia, and between cerebellar lesions and detrusor areflexia. The correlation between detrusor dysfunction and high total disability score disappeared when patients with high pyramidal scores were excluded. No correlation could be detected between somatic dyssynergia and the various neurological lesions.
