Experimental Study On Abdominal Surface Recording Of Electromyographic Activity Of Bladder In Rabbit

Objective: To develop a method for recording vesical electromyographic activity from body surface by systematically evaluating whether abdominal surface electromyography is representative of vesical electrical and contractile events. And therefore to search for a noninvasive method for recording vesical activity.Methods: Electrical activity was acquired by using of bipolar electrodes attached simultaneously to the vesical wall and to the abdominal surface of rabbits. Intravesical pressure was recorded with a pressure transducer inserted in the vesical cavity. Correlation analyses were performed between them after simultaneous recording.Results: There were no obviously bursts recorded from either the bladder or the abdominal surface during filling period, and the Intravesical pressure also had no obvious changes. In voiding period,...
