[New technical possibilities for simultaneous cystometry]

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.
