3.4 Cystometry Study
A Cystometry study involves filling the bladder and determining the Detrusor pressure Pdet
= Pves – Pabd (the difference between the pressure inside the bladder (Pves) and the
pressure inside the abdomen (Pabd)). The Cystometry study provides one phase to
complete filling and voiding. This allows the user flexibility in procedure structure.
Starting the Cystometry Study
Start the Cystometry study as described in the Starting a Study section on page 30.
The study requires the use of the Urocap NXT, Roam NXT, NXT Go Pump Hub, and
Bluetooth Dongle NXT. Ensure all modules are connected in the Synergy Software. Ensure
that the Urocap NXT and Roam NXT are fully charged. The Synergy Software will recognize
the PIM NXT and the Roam NXT as one device under the title Roam NXT.
Performing the Cystometry Study
3.4.2.1 Preview phase
Complete patient and consumables setup during this phase. Refer to the Setting Up
Consumables and Preparing the Patient section on page 24. Once patient and pump setup
are complete proceed to the Cystometry Phase.
3.4.2.2 Cystometry phase
Click the Start Cystometry Study button.
Click the Pump On button to start the Infusion Pump and begin filling the
bladder. Click Smart Pump Up or Smart Pump Down buttons to increase or
decrease the pump speed, respectively.
NOTE: To change the infusion bag click the Change Infusion Fluid button. A popup
window will appear, and the study will pause. If desired, update the Fluid Density setting
using the dropdown menu available on the popup window and click OK to resume the study.
Fluid density options must be configured in the Workflow Configuration window before
starting the study. Refer to the Customizing Workflows section on page 56.
Encourage the patient to give feedback on sensation or urge. Mark relevant events
(e.g.: First Sensation, First Desire, Strong Desire, etc.) by clicking the First
Sensation drop-down menu and selecting the relevant event.
When the patient starts to feel discomfort or fullness, stop the Infusion Pump by
clicking the Pump Off button in the Synergy software.
Caution: Infusion can be stopped at ALL TIMES by pressing the grey pump stop button
on the NXT Go Pump Hub, by opening the pump door, or by disconnecting the filling tube
from the catheter or the water bag.
Click the Permission To Void button and ask the patient to void through the commode
chair into the Urocap NXT setup. See
Preparing the Urocap NXT for a reference image of the Urocap NXT Setup. If the
patient fails to void re-click the Permission to Void button to create a new
marker; this action will shift the previous marker to ‘Attempt to Void’. If the
Status DRAFT Effective
