Scanning the bladder and measuring its volume is a common procedure usually performed by nurses. It may be done for a variety of reasons, but achieving accuracy is key. Catheterization-based methods may be the most accurate, but non-invasive ultrasound is a lot more attractive. With conventional ultrasound one must be very careful to properly gauge the margins of the bladder, then essentially use a ruler on a 3D object, and finish using a formula that really only provides a rough estimate. EchoNous, based in Redmond, Washington, has released a device that lets nurses measure bladder volume faster and with greater confidence, hopefully resulting in more accurate numbers. Read more.
