Noninvasive Optical Monitoring of Bladder Filling to Capacity Using a Wireless Near Infrared Spectroscopy Device.

ABSTRACT

Lack of bladder fullness sensation is an issue that arises in different neurogenic conditions and in addition to influencing patients' quality of life, can result in serious kidney damage. We describe a wireless wearable sensor for detecting bladder fullness using near infrared spectroscopy (NIRS). The sensor has been tested in vitro and in vivo to verify its feasibility and is shown to be capable of detecting changes in bladder content noninvasively.
