A New Method with Fiberoptic Transducers Used for Simultaneous Recording of Intravesical and Urethral Pressure During Physiological Filling and Voiding Phases

A new technique using fiberoptic transducers for simultaneous registration of intravesical and urethral pressures during the physiological filling and voiding phases is described. The method, which is simple, exact and stable, was used on several patients with different urological problems. The study shows that the measurement technique and the fiberoptic transducer system are suited for clinical use.
