PURPOSE
Vesicoureteral reflux and residual urine ultimately cause kidney damage and urinary infections in
both neurogenic bladder and bladder dysfunction. In both scenarios, it would be useful to define
the presence of Post Voiding Residual (PVR), in an outpatient basis and in real time, in order to
proceed to clean catheterization or new urination, as appropriate, and only if necessary. A portable
and personal ultrasound bladder scanner, that could be handled by each patient, was designed.
The goal was to create a device that would only discern, in an outpatient basis, and in real time,
whether a significant PVR exists or not.
MATERIAL AND METHODS
A B mode ultrasound transducer device capable of detecting “water” signal and translating this
quantitative signal into a color code was designed. Color code was defined according to International
Children Continence Society PVR limit values: green (<20 cc), amber (20-50 cc) and red (> 50 cc),
depending on the amount of PVR detected after micturition or catheterization. This new proto-
type has been developed under collaboration of both public regional health and bio-engineering
institutions.
RESULTS
A 390 gr and 14 cm ultrasound probe that includes:a) a convex 2.30 MHz B mode linear transducer
and b) a 12 V LED driver or color-coded terminal (red, amber, green) that lights after bladder volume
measurement. If green lights, there is no need for catheterization nor double micturition. Accuracy:
10% of detected PMR; volume range: 0-500. Scanning method: sectorial, 180º; Maximal depth:
100 mm. Data can be downloaded from the probe to a personal computer throught an USB port.
CONCLUSIONS
This personal and portable ultrasound device is actually under phase II clinical essay. Clinical
benefits include: portability, easy understanding, easy diagnosing, preventing unnecessary cath-
eterization, (verifies empty bladder) and monitoring postoperative urinary retention. This personal
and portable traffic light like ultrasound bladder scanner facilitates management and understanding
of PVR
