- Charging: USB charging cable, about 2 hours to charge (see specifications)
- Category: Bladder Ultrasound
Product overview
The BProbe-5 is a single handheld probe. It sends the image over Wi-Fi to a phone or tablet, so the set is easy to carry and quick to set up. The probe scans in 4D (four-dimensional), which keeps the image clear and the volume calculation consistent.
Intended use. The device is intended for measuring post-void residual bladder volume in patients with urinary incontinence, to support the decision on whether catheterisation is needed and how much urine should be drained, and to provide visual monitoring during catheterisation so that blind insertion and bladder injury can be avoided.
In urology it is used to grade acute and chronic urinary retention, which helps decide the timing of catheterisation and of surgery, to assess the effect of neuromodulation, and to grade urethral obstruction or prostatic enlargement.

Where it is used
- Urology - grading of acute and chronic urinary retention, to help decide the timing of catheterisation and of surgery; assessment of the effect of neuromodulation; grading of urethral obstruction or prostatic enlargement.
- Obstetrics - postpartum stress urinary incontinence; assessment of the degree of postpartum pelvic floor muscle damage.
- Gynaecology - assessment of pelvic floor nerve and muscle damage after pelvic tumour surgery, to help decide between surgery and rehabilitation.
- ICU - timing of intermittent catheterisation for patients on long-term catheter drainage, to reduce the number of insertions, lower the infection risk and support recovery of spontaneous voiding.
- Neurology - assessment of detrusor and sphincter damage in patients with neurogenic bladder.
- Nursing - timing of catheter removal after surgery, to shorten catheter dwell time and lower the infection risk.
- Rehabilitation - monitoring the effect of pelvic floor rehabilitation; planning bladder retraining programmes and providing a basis for assessing recovery of bladder function.
- Emergency - assessment of acute urinary retention and guidance for catheter insertion; assessment of suspected bladder injury or rupture after trauma.
- Radiotherapy - assessment of bladder function during radiotherapy in patients with pelvic or bladder tumours.
Product features
- One probe only - small, light and easy to carry.
- Wireless connection - free and easy to operate.
- High accuracy (error below 5%).
- Fast scanning and volume calculation (about 2 seconds).
- Measurement range of 50-2000 mL.
- Electronic convex 4D scanning with a high channel count and element count - clear image, no mechanical scanning distortion.
- R20 probe - a wide scan angle and a wide coverage area.
- High-resolution rotary encoder - precise positioning, no routine calibration service required.
- Refined volume algorithm, stronger bladder wall recognition and more accurate contour tracing, together with a higher-accuracy probe.
- The algorithm is less affected by bladder shape and size. Sex, age group and special situations such as hysterectomy do not need to be entered, and small or unusually shaped bladders are measured with better consistency.
- Good recognition of bladder walls with adherent air, so the volume can still be measured when the bladder is not full.
- Where a bladder wall is difficult to trace, the abnormal image can be added to the training set and used to improve the contour tracing.
- Real-time imaging during scanning, which supports visual monitoring while a catheter is inserted or removed.
