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

The aim of this study is to determine if there is a significant difference between air-charged and water-perfused urethral pressure measurements, namely maximum urethral closure pressures in urodynamic testing.

There have been previous studies that investigated the differences between air-charged and water-perfused catheters; however, this current study introduced a single catheter technique that was conceptualized in order to overcome the limitations of double-catheterization including better patient comfort, decreased alteration of the natural urethral closure mechanism and a lessened risk of catheter cross-talk.
