Comparison of Water and Air-Charged Transducer Catheters in the Evaluation of Cystometrogram Pressures

Comparison of Water and Air-Charged Transducer Catheters in the Evaluation of Cystometrogram Pressures

The primary objective of this study is to demonstrate reproducibility of air-charged versus water-perfused catheters when measuring stress point pressures, such as coughs and valsalva movements in urodynamic studies.

The comparison was analyzed during a cystometrogram (CMG) test. The present study introduced a single catheter technique that was conceptualized for the CMG. We believe that the single, dual catheter, fastidious work, and the same experience clinician throughout the study will provide analogous point pressures for coughs and valsalva movements in both water-perfused and air-charged catheters.
