Visualization of Bladder and Fluid Collections

Ultrasound excels at identifying fluid collections, and a number of possible ED applications utilize this property. Unless devoid of urine, the bladder is very easy to identify on ultrasound, and most ultrasound machines have the ability to estimate bladder volume based on easily performed measurements. The invasive and painful procedure of catheterizing the bladder to determine postvoid residual volume can often be obviated by ultrasound. Furthermore, suprapubic bladder catheterizations and aspirations are easier and more likely to be successful when guided by ultrasound. Identifying abscesses is another area where ultrasound can be of assistance. With the use of high-frequency transducers (Z.5 to 10 MHz), the presence or absence of fluid collections within subcutaneous masses can be determined. If an abscess is present, the depth of the abscess and surrounding structures (e.g., vessels) can be identified. The fluid within the abscess appears anechoic or has scattered echoes within a hypoechoic collection, representing necrotic debris. Just as ultrasound can identify hemothoraces, it can identify even small pleural effusions and guide aspiration attempts.
