Incontinence Clinical Trial
— ACWFOfficial title:
In Vivo Comparison of Air Charged Catheters With Water Filled Catheters for Intravesical and Intrarectal Pressures Recording During Urodynamic Study
Various systems to measure intravesical and intrarectal pressure during urodynamic testing;
especially cystometry, exist. Water filled tube -systems are the most commonly used and
should be regarded as the contemporary standard. A water filled system is however sensitive
to tube and or patient movement artefacts and prone to erroneous calibration. Air charged
catheters are less sensitive to patient and especially tubing- movements, and calibrate
easier. However, in vitro tests have demonstrated that air charged catheters respond
somewhat slower and relatively damped, especially to rapid pressure changes as in
(simulated) coughing, in comparison with water filled systems. The clinical relevance of
these observations is unknown.
This is a study to compare the technical reliability and clinical applicability of the two
types of catheter systems for cystometry in a synchronous double catheter testing procedure
in a prospective group or patients scheduled for urodynamic investigation.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | The difference between the water filled catheter recorded and simultaneously air charged catheter recorded maximum pressure (amplitude)during the bladder filling phase of urodynamic test. | Null hypothesis: the (absolute mean) difference between the water filled catheter recorded and simultaneously air charged catheter recorded maximum pressure (amplitude) observed with a dominant detrusor pressure event during urodynamic filling as obtained with both systems is close to zero. | acute comparison during one test with two types of catheter | No |
Secondary | responses to relevant pressure events: end fill pressure, maximum contraction pressure, maximum pressure at overactive detrusor contraction and maximum cough pressure. | to test the clinical feasibility (-mean absolute- pressure responses differences) of the air charged system, against the contemporary clinical standard. Perfect feasibility of air charged catheter system is achieved when the measured pressures are equal (difference zero) to the water filled system in all performed measurements in all situations. | acute comparison during one test with two types of catheter | No |
