With the introduction of integrated semiconductor pressure admitters into the urodynamic examination methodology an optimization of the manometry of the bladder and the urethra was carried out, since the changer of the measuring value in this case is directly situated in the lumen of the bladder. Thus it is achieved that the possibilities of errors which are connected with the conventional measuring method with the catheter system filled with fluid or gas, such as movements, concussions, hydrostatic influence of the coupling medium by different altitude level of the catheter and the connection tube, respectively, but also constipations in haematuria or excretions of the mucus may be excluded. The presented tip manometre IBW 74 due to its measures and radiopaque properties is also suited for the measurement of the pressure on the upper urinary tracts including the pyelon. Hereby the pressure signals gained are further elaborated through a special insertion for the biomonitor system and thus may be recorded on every multiple recorder.
随着集成半导体压力传感器引入尿动力学检查方法，膀胱和尿道测压得以优化，因为在这种情况下测量值的变化直接发生在膀胱腔内。这样就实现了排除与传统的充满液体或气体的导管系统测量方法相关的误差可能性，比如移动、震荡、导管和连接管不同高度水平下耦合介质的静水压力影响，还有血尿中的便秘或黏液分泌。所展示的尖端测压计IBW 74因其尺寸和不透射线特性，也适用于测量包括肾盂在内的上尿路压力。由此获得的压力信号通过生物监测系统的特殊插入装置进一步处理，从而可以在任何多通道记录仪上记录下来。
