Fiber-optic versus microtip transducers in simultaneous urethrocystometry. A comparative study.
A comparative study of a new fiber-optic transducer versus a microtip transducer was performed in 13 females. A good correlation was found on bladder pressure. The urethral pressure diverged considerably, as the pressures measured with the fiber-optic transducer were about two thirds of the pressures found with the microtip. The functional urethral length measured with the fiber-optic transducer was also shorter.
