Effects of Selective β2 and β3-Adrenoceptor Agonists on Detrusor Hyperreflexia in Conscious Cerebral Infarcted Rats

Purpose: We evaluated the effects of β-adrenoceptor agonists on detrusor hyperreflexia in cerebral infarcted rats.Materials and Methods: To produce cerebral infarction in Sprague-Dawley rats the left middle cerebral artery was occluded by introducing a monofilament nylon thread into the artery. In sham operated rats the same artery was exposed but not occluded. After these operations cystometric and cardiovascular experiments were performed with no anesthesia or restraint.Results: After the operation bladder capacity was significantly decreased and voiding pressure was significantly increased in cerebral infarcted but not in sham operated animals. The difference in cerebral infarcted and sham operated rats was significant for each parameter (p
