title: New technical possibilities for simultaneous cystometry.
abstract: With the introduction of integrated semiconductor pressure pick-ups into the urodynamic methodology of analysis, the bladder and urethral manometry has been optimized, since the measuring transducer is positioned directly inside the lumen of the bladder. In this way, it is possible to eliminate the errors of conventional measuring methods with the liquid-filled or gas-filled catheter system, for example movements, vibrations, hydrostatic influences on the coupling medium by different vertical positions of the catheter or connecting tube, as well as cloggings due to haematuria or secretion of mucus. Owing to its dimensions and radiopaque properties, the IBW 78 tip manometer is suitable also for the pressure measurement in the upper urinary passages including the pyelon. The pressure signals obtained are further processed in a special plug-in unit for the biomonitor system, and thus they can be recorded on any multiple recorder.
