Bladder function in patients with myotonic dystrophy

Ten patients with a clinically and neurophysiologically established diagnosis of myotonic dystrophy underwent urodynamic evaluation of the lower urinary tract. Eighty percent of the patients had urinary complaints by history, but we were not able to identify a homogeneous bladder dysfunction pattern by voiding and incontinence chart, flowmetry, cystometry, or sphincter electromyography.
