Bladder scanning is one of the most common use cases in point-of-care ultrasound—and a question that comes up frequently, especially from the nursing team, is:
“Can ultrasound really replace a bladder scanner?”
The answer is yes—and with the Smart Bladder tool, it can be fast, simple, and accurate.
Bladder Scan in 5 Simple Steps
At a glance, this is all it takes:
- Scan transverse & freeze
- Tap Smart Bladder
- Accept measurements
- Rotate probe (longitudinal) & freeze
- Tap Smart Bladder again --> Volume auto-calculated
That’s it.

Breaking It Down
While the workflow is simple, a quick understanding of each step makes all the difference:
1. Acquire and freeze (transverse view)
Start by obtaining a clear short-axis (transverse) image of the bladder and freeze the image. Proper probe positioning is key here.

2. Activate Smart Bladder
Tap Smart Bladder and the system will automatically detect and display the first two diameters.
If needed, you can fine-tune the measurements by adjusting the markers.
3. Accept measurements
Confirm by tapping Accept. The system will store the measurements and prepare for the second plane.

4. Rotate and freeze (longitudinal view)
Rotate the probe 90°, acquire the long-axis image and freeze.
5. Tap Smart Bladder again
Once confirmed, the system automatically calculates the bladder volume—no manual formulas, no guesswork.

Technology Supporting Skills
It’s important to highlight:
Using ultrasound for bladder scanning still requires basic scanning skills—correct probe placement and image recognition.
What Smart Bladder does is simplify the process, reduce variability, and improve confidence—especially in busy clinical environments.
