RecruitingDevice studyMeasurement of Bladder Pressure With a Novel External Device (Cystomanometer) - Home UseThe investigators have developed a novel pressure monitoring device that hooks to standard urinary catheters that are used by patients with a neurogenic bladder on daily clean intermittent catheterization. The device has already been demonstrated to be accurate compared to the gold standard in clinic urodynamics. This study will assess the patients and care givers ability and experience using the device in a home setting.
