Abstract :
The resistance of the urinary bladder, as measured between two electrodes attached to the external bladder wall at frequencies above 100 kHz, is proportional to the bladder volume for properly placed electrodes. The feasibility of using an oscillator, the frequency of which is controlled by the bladder interelectrode resistance, to provide an electrical signal proportional to bladder volume for use in connection with an electronic bladder stimulator is presented. The implications of this result are discussed.
