Catheter-mounted microtransducers for urethral pressure measurements were introduced by Karlson35 in 1953. The microtransducer was the author s own design 36 and the sensing part consisted of a small rubber tube filled with granular carbon. The resistance of these granules changed as the pressure exerted on the device changed. Microtransducers available today are either of semiconductor 37-39 fiber-optic type 40-42 or (as disclosed in this study) air-charged balloon sensing catheters. These catheters are commonly used in clinical studies.9 43-45 The main advantage of catheter-tipped sensors are that they measure pressure at the catheter location where the sensor is located thus greatly simplifying calibration and zeroing of the system except TDOC which zeros to atmosphere by the open system before closing the air column.. The pressure-sensing
