Infused volume
The infused volume is the volume of the fluid pumped into the patient during
an investigation.
Bladder filling
The filling of the bladder at the end of the investigation. It is calculated as the
sum of the initial bladder filling and the infused volume subtracted with the
volume lost through leakage.
Volume lost through leakage
The volume lost during the cystometry. This number is determined only when
a flowmeter is connected and used during the investigation.
Maximum bladder capacity
The maximum bladder capacity is the maximum infused volume.
Residual urine
The residual urine is defined as the volume of the fluid remaining in the
bladder immediately following the completion of micturition. It can be entered
manually at the end of a cystometry.
Pves max
Pves max is the maximum bladder pressure (Pves) during the investigation.
This parameter is only valid as an absolute parameter if the transducer is
zeroed at atmospheric pressure. This parameter is affected by cough peaks,
which can be eliminated with artifact markers during the investigation and/or
analysis.
Pdet max
Pdet max is the maximum detrusor pressure during the investigation. The
detrusor pressure is that component of the intravesical pressure that is created
by forces in the bladder wall (passive and active). It is estimated by subtracting
abdominal pressure from intravesical pressure. However, artifacts on the
detrusor pressure trace may be produced by intrinsic rectal contractions.
These can be eliminated with artifact markers during the investigation or
analysis.
