Advancing Towards a Wearable Ultrasound Sensor for Real-Time Bladder Volume Monitoring to Reduce Catheterization in...

Area of Science:

• Urology
• Biomedical Engineering
• Medical Devices

Background:

• Bladder monitoring is crucial in urological care, especially for conditions like neurogenic bladder.
• Urethral catheterization (UC) is standard but carries risks highlighted by the CDC.
• Current methods for bladder volume measurement can be invasive and increase infection risk.

Purpose of the Study:

• To introduce a novel wearable ultrasound sensor for real-time bladder volume monitoring.
• To develop an energy-efficient solution to reduce reliance on urethral catheterization.
• To present a proof-of-concept for a wearable bladder monitor addressing current limitations.

Main Methods:

• Development of a 32-channel bladder volume measurement wearable ultrasound sensor (BV-WUS).
• Utilized a low frame rate for reduced power consumption (0.125 W) and extended battery life.
• Incorporated efficient data communication, a low-power FPGA, and wireless connectivity.

Main Results:

• The BV-WUS demonstrates a technologically advanced, energy-efficient solution for real-time bladder monitoring.
• Achieved low power consumption suitable for extended use.
• Established a foundation for future development, including a 3D rotating transducer.

Conclusions:

• The BV-WUS platform is a viable proof of concept for wearable bladder monitoring.
• This innovation offers a less invasive alternative to traditional catheterization.
• The technology has the potential to reduce risks and costs associated with bladder management.
