How to Perform a Study
Laborie NXT Pro Owner’s Manual LBL-00146 [C], MAN2010 43
Urethral Pressure Profile
To start a Urethral Pressure Profile (UPP), follow the instructions provided in the section
Customizing Workflows on page 59
for adding a UPP phase to a study, or select a study
template that contains a UPP phase. Be sure to complete patient and consumables setup as
instructed in the section
Setting Up Consumables and Preparing the Patient on page 25.
3.5.2.1 Manual Urethral Pressure Profile
To complete a manual Urethral Pressure Profile, perform the following steps:
In the UPP phase, confirm that the positioning of the urethral pressure sensor
(Pura) is just proximal to the bladder neck. To position the sensor, manually
withdraw the catheter at a moderate rate. When Pura begins to rise, stop
withdrawing and return the catheter slightly back into the bladder.
Click the Rest Profile button to start the rest profile.
Very slowly begin manually withdrawing the vesical catheter, pulling at
approximately 1 mm/sec by using the measurement marking on the catheter.
Vesical pressure should remain stable, whereas urethral pressure and closure
pressure (Pclo) will rise and fall, indicating that the sensor is travelling through
the urethra.
When Pclo returns to zero, stop pulling and click the Rest Profile button to end
the profile.
Reinsert the catheter and position it just proximal to the bladder neck to complete
a Stress Profile using the Stress Profile button. After the required number of
profiles is complete, finish the selected study.
3.5.2.2 Mechanical Urethral Pressure Profile
For a mechanical Urethral Pressure Profile, in the Device Manager window, ensure that the
UPP Puller NXT is connected. Select the Puller option and then, in the Workflow
Configuration dialog box, in the Profile Settings section, set the Puller Speed before
starting the test. To complete a mechanical Urethral Pressure Profile, perform the following
steps:
In the UPP phase, confirm that the positioning of the urethral pressure sensor
(Pura) is just proximal to the bladder neck. To position the sensor, manually
withdraw the catheter at a moderate rate. When Pura begins to rise, stop
withdrawing and return the catheter slightly back into the bladder.
Ensure that the UPP Puller NXT is in the start position. If the Rest Profile and
Stress Profile buttons are inactive in the Synergy control panel, click the Puller
Return button to return the UPP Puller to the start position.
Feed the catheter through the catheter guide and use the catheter clamp to
secure the catheter to the UPP Puller NXT.
Select the Rest Profile (On) button to start the rest profile. The UPP Puller will
begin pulling at the speed selected in the Workflow Configuration dialog box.
NOTE: UPP Puller NXT speed can be adjusted only in the Workflow Configuration
dialog box prior to starting the test.
Select the Rest Profile (Off) button to mark the end of the profile. Click the
Puller Return button to return the UPP Puller NXT to the start position.
