Abstract: BladderScan^® Technology

Bill Barnard, Gerald McMorrow, Roger Sahm, and Brian Wilson. "BladderScan Technology." Diagnostic Ultrasound Corporation, 1994.

Objectives:
* To compare the accuracy of the BladderScan BVI 2500 to Abdominal Ultrasound (AUS) methods of measuring bladder volume.

Methods:
* Thirty-eight examinations were conducted on thirty-six adults. Each subject was examined with up to five BVI 2500 instruments. The subject was then examined with an ATL Ultramark-8 (UM8) general purpose ultrasound instrument. Immediately after the examinations, the subject voided into a UFS 1005 Uroflowmeter in order to document the voided bladder volume.

Results:
* "The BVI 2500 demonstrated significantly less error than each of the six AUS methods. In addition, r² was significantly higher for the BVI 2500 than for the six AUS methods."

Conclusions:
* "The BladderScan BVI 2500 provides a portable, rapid, accurate method for bladder volume determination. Clinical results demonstrate that the BladderScan is simpler to use and more accurate than abdominal ultrasound instruments."
