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
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.
