Example reusable solid-state catheter
The procedure to prepare the catheters is as follows:
▪
Pre-wet the catheter in distilled sterile water as described in manual of the
manufacturer (the minimum period is two minutes).
▪
Connect the pre-wetted catheter to the WPU as follows.
o
Connect P
ves
(vesical/bladder pressure) to P1
o
Connect P
abd
(abdominal pressure) to P2
o
Connect P
ura
(urethral pressure) to P3
▪
Press the
Zero
all
button to zero all pressures pressure (the pressure
sensors must be covered with approx. 1 cm of water).
▪
Disinfect the genital area.
▪
Insert the bladder catheter and position the vesical pressure sensor (P
ves
) in
the bladder. If applicable, position the urethral pressure sensor (P
ura
) at the
maximum urethral pressure and fix the catheter.
▪
Insert the rectal catheter into the rectum and fix the catheter.
▪
Ask the patient to cough to check the registration of all pressures. The
spikes of P
ves,
P
abd
and P
ura
should rise equally in response to the cough
and the detrusor pressure (P
det
) should remain relatively flat.
▪
Start the investigation (cystometry, pressure-flow study, UPP or gynecology

Single-Use e
•Sense Solid-State Catheters
Single-use e
•Sense solid-state catheters can be used to perform pressure
measurements in bladder and urethra (using one blue connector) and rectum
(red connector). The single-sensor bladder catheter has one pressure sensor
for bladder pressure (P
ves
). The dual-sensor catheter has a sensor for bladder
pressure and urethra pressure (P
ves
and P
ura
).
The bladder catheters have a filling lumen to fill the bladder. The abdominal
catheter has one sensor for measuring the abdominal pressure (P
abd
).
