Conditions

Neurogenic Bladder, Urinary Tract Infections

Brief summary

The Uroshield device is a commercially available device with two parts: a disposable actuator which attaches to the external portion of the catheter and a portable battery. The device sends out low-frequency ultrasound waves which run along the surfaces of the catheter. These acoustic waves prevent bacteria from adhering to the catheter and prevent the formation of biofilm. Our objective is to conduct a pilot study to determine if the UroShield device can reduce bacteriuria and catheter biofilm formation among neurogenic bladder patients with an indwelling catheter, as well as improve urinary quality of life and symptoms.

Interventions

DEVICEUroshield

The Uroshield device sends out low-frequency ultrasound waves which run along the surface of the catheter.

The sham Uroshield device is identical to the active machine, but it does not send out low-frequency ultrasound waves along the surface of the catheter.

Design outcomes

Primary

MeasureTime frameDescription
Bacteriuria30 daysProportion with bacteriuria \>10\^5 cfu at day 30

Secondary

MeasureTime frameDescription
Neurogenic bladder symptom score (NBSS)30 daysValidated symptom score that measures symptoms related to neurogenic bladder dysfunction and urinary quality of life. Total scale ranges from 0-74, and a lower number is considered a better outcome and represents lower symptom burden.
Patient subjective rating of amount of sediment/debris at the end of the 30 days30 days
Total bacterial cell counts30 days
Microbiome comparison of biofilms30 days
Scanning electron microscopy of biofilms30 days
