2163 Non-Invasive Measurement of Bladder Pressure in Men: A Leap Forward

Continuous non‐invasive measurement of bladder voiding pressure using an experimental constant low‐flow test

“…To allow restriction of urine flow to a very low rate using a penile cuff, the ideal device would respond immediately to initiation of flow in order to rapidly achieve a pressure close to that of the bladder, with subsequent fine control of pressure in the cuff to keep flow at a constant low rate. We developed a prototype pilot device (Regional Medical Physics Department, Newcastle upon Tyne, UK, patent pending8) which incorporates an air pump, reservoir and variable orifice valves allowing mechanical cuff pressure control. These are controlled by a PIC microcontroller (Microchip technology, Chandler, AZ) programmed with firmware governing the feedback loop (see Fig.…”
