Portable bladder volume measurement at the point of care

The MDPro HD2 Handheld Bladder Scanner is a compact ultrasound device designed to measure urinary bladder volume non-invasively. It projects ultrasound energy through the lower abdomen, produces an image of the bladder, and automatically calculates the estimated bladder volume.

Its handheld, all-in-one design allows healthcare professionals to perform bladder-volume and post-void residual assessments in examination rooms, patient rooms, long-term care facilities, rehabilitation settings, and other clinical environments without moving the patient to a dedicated ultrasound department.

The HD2 is intended for use by qualified medical professionals. It can support assessment of urinary retention and post-void residual volume and may help clinicians make more informed decisions about whether catheterization is necessary. It is not intended to replace clinical judgment, diagnostic evaluation, or facility protocols.

Easy and Expert operating modes

The HD2 offers two scanning modes to accommodate different levels of ultrasound experience.

Easy Mode provides visual guidance to help the operator position the scanner over the bladder and locate the appropriate scanning area.

Expert Mode displays a real-time two-dimensional ultrasound image, allowing experienced clinicians to evaluate bladder positioning and image quality before completing the measurement.

After the bladder is positioned correctly, the device analyzes the ultrasound image and displays the calculated bladder volume.

Automatic volume calculation

The scanner uses a mechanical sector probe and internal image-processing technology to create a two-dimensional bladder image and calculate bladder volume automatically.

The displayed measurement range is 0 to 999 mL, with a 1 mL display resolution. The manufacturer’s user manual lists volume-measurement accuracy as ±15% or ±15 mL, while the current IMCO listing describes the HD2 as having ±12% accuracy. Because the sources differ, the precise accuracy specification for the IMCO-supplied revision should be confirmed before publishing the product as Active.

Voice annotation and data storage

The HD2 includes voice-recording capability for associating spoken information with a completed scan. Measurement data may include the bladder ultrasound image, measured bladder volume, and recorded audio.

The system stores information on an SD card and can generate image, text, and audio files for review on a computer. This is file-based data export rather than confirmed direct EMR or EHR integration.

Compact and battery-powered

The HD2 combines the main unit, display, and ultrasound probe in a handheld design weighing approximately 500 grams, or 1.1 pounds.

The rechargeable lithium-ion battery provides more than 3.5 hours of listed scanning time and more than eight hours of standby time. A base and carrying bag support storage and transport between clinical areas.

No routine annual calibration service advertised

The IMCO listing identifies the HD2 as requiring no annual calibration. This may help reduce the recurring service burden associated with some bladder-scanning systems.

The manufacturer’s manual still includes a device-calibration setting, so users should follow the current manufacturer instructions, institutional quality procedures, and any service recommendations supplied with the delivered unit.

Common Clinical Applications

The MDPro HD2 may support qualified healthcare professionals during:

• Bladder-volume assessment
• Post-void residual measurement
• Evaluation of suspected urinary retention
• Postoperative urinary-retention assessment
• Intermittent-catheterization decision support
• Continence-management workflows
• Urology and primary-care examinations
• Long-term care and rehabilitation assessments
• Bedside bladder-volume checks
• Selected urgent-care evaluations

Bladder scanning may help clinicians avoid catheterization when it is not clinically necessary, but decisions must be based on the patient’s condition, clinical findings, and established facility protocols.

Important Limitations and Safety Information

The HD2 is intended for operation by qualified medical professionals.

The manufacturer’s manual states that the device should not be used for fetal applications or on pregnant patients.

It should not be used on patients with ascites because fluid outside the bladder may affect measurement accuracy.

Do not scan over open or damaged skin or wounds in the suprapubic region.

The probe must not be immersed in water or other liquids.

Ultrasound gel should be used during scanning to maintain appropriate contact between the probe and the patient’s skin.

Measurements should be interpreted together with clinical findings and should not serve as the only basis for diagnosis or treatment decisions.
