Abstract

Although clinical reports concerning voiding dysfunction after cerebrovascular disease are observed, no experimental studies have been carried out using an animal model. This study was performed to establish an animal model to evaluate neurogenic voiding dysfunction associated with cerebral infarctions. Male Sprague-Dawley (S-D) rats weighing between 250 to 350 g were used. To induce regional cerebral infarction in rats, 4-0 monofilament nylon thread was introduced through the left internal carotid artery into the origin of the left middle cerebral artery. Cystometric examination was performed in conscious rats through a catheter chronically implanted into the bladder dome. Changes in body weight and bladder capacity were studied. The effects of intravenous oxybutynin hydrochloride, atropine and nifedipine on the conscious rat bladder were examined. By measuring the contractile response to field stimulation with added atropine and alpha, beta-methylene-ATP, the proportion of muscarinergic and purinergic innervation was compared between them. Bladder capacity in cerebral infarcted rats was significantly decreased just after middle cerebral artery occlusion, and 14, 21 and 28 days after occlusion reached less than half that in sh...Continue Reading
