ABSTRACT

Indwelling pressure transducers find application in three types of measurements in the genitourinary area: as a means of measuring pressure in the bladder to indicate volume, as an indicator of effectiveness of bladder stimulation for urinary evacuation and as a means of measuring pressure in inflatable devices for urethral occlusion. Pressurization and pressure-monitoring devices are basic for three purposes in the lower urinary tract. In a given patient, basically the pressure in the bladder is found to increase in a fairly reproducible fashion as a function of the volume. The pressure-sensing devices are used in conjunction with electrical bladder stimulation to produce bladder evacuation. Pressure telemetry techniques or indwelling transducers are useful for monitoring: bladder pressure as a means to measure volume, bladder pressure as a means to determine efficacy of stimulation techniques and function of an implanted artificial sphincter system.
