Brief Summary:
The investigators have developed a novel pressure monitoring device that hooks to standard urinary catheters. The investigators will be testing how the pressure measurements recorded with this device compare to the gold standard measurement of urodynamics.

Condition or disease Intervention/treatment Phase
Urinary Bladder, Neurogenic Urodynamics Diagnostic Test: Urodynamics Testing Not Applicable

Detailed Description:

For patients with neurogenic bladder, regular monitoring of bladder pressure and capacity is a critical component of maintaining renal and urinary health. This monitoring is currently done by in-office urodynamics testing (UDS). This testing is done intermittently, leaving open the possibility of worsening of bladder function and renal deterioration between testing sessions.

This study utilizes a novel pressure monitoring device which is portable and hooks to the end of a standard urinary catheter. The investigators will be investigating if this device can achieve similar pressure measurements as UDS. The investigators hope is that this device will provide similar measurements to UDS, and can be developed as a home bladder-pressure monitoring tool.

This study will enroll children with neurogenic bladder who are currently undergoing UDS as part of their regular care. The measurements will be taken as part of the standard UDS protocol (with insertion of the UDS catheter) and will then be compared to the values obtained with UDS testing.

Primary Purpose: Other
Official Title: Measurement of Bladder Pressure With a Novel External Device, Comparison to Urodynamics Testing
Actual Study Start Date : April 15, 2018
Estimated Primary Completion Date : June 30, 2021

Arm Intervention/treatment
Neurogenic Bladder Patients
Patients with neurogenic bladder undergoing urodynamics testing
Diagnostic Test: Urodynamics Testing
Urodynamics utilizes a small catheter to fill the bladder and continuously measure pressure and volume giving information on bladder function and compliance

Primary Outcome Measures :
  1. Bladder Pressure [ Time Frame: During UDS testing ]
    Pressure of the bladder at bladder capacity
