Metrological properties of profilometry catheters in an experiment

Using an experimental phantom of the urethra made from the urethra of the bull, compression pressures acting from one side as well as circular pressure were simulated. Both the measurement with the perfusion method using catheters with one or more openings and the measurement with catheters with a measuring chamber have been shown to provide good reproducibility, however, the signal is strongly dependent on the position of the catheter in the urethra. The same applies to the catheter with an incorporated sensor (MikroTip). Overall information on the pressure from the whole circumference of the urethra was obtained only from an air-charged balloon catheter (T-DOC). This device also yielded the best sensitivity rates as well as the lowest diffusion rates.
