title: Simultaneous urethro-cystometry with a new technique.
abstract: A new technique for studying simultaneous intravesical-intraurethral pressure is described. The basic principle of our technique is pressure recordings with the aid of micro-transducers. These micro-transducers have excellent frequency response, are easy to calibrate and to sterilize and are free from artefacts induced by motion. They permit a more accurate study of the pressures within the bladder and the urethra than catheter-transducer systems described earlier. Using electronical subtraction the closure pressure can easily be measured under static and dynamic conditions. Typical pressure diagrammes obtained with this catheter system are presented.
