Background
- Identification: anechoic (black) fluid within a structure defined by hyperechoic (white) appearing borders
- Bladder volume = length x width x heigth x 0.52
Technique
- Use phased array probe
- Find the bladder suprapubically
- usually need to turn down far gain 2/2 acoustic enhancement from bladder
Clinical Uses
- Look for abdominal free fluid
- Can be used to calculate post void residual non invasively
- Confirm foley placement by visualizing balloon
