PURPOSE
In the Netherlands, the prevalence of daytime incontinence affects 6-9% of the children older than four year old.
Dysfunctional voiding (DV) refers to children who do not develop or even lose the ability to consciously recognize a full
bladder. An ultrasonic bladder monitor which is able to sense the bladder filling and is capable of alarming the user
before voiding, may be useful for training these children. A new, wearable and wireless ultrasonic bladder device: the
URIKA Bladder Monitor is developed. In this study, the aim is to evaluate the feasibility and validity of the URIKA
Bladder Monitor in the detection of bladder filling.
MATERIAL AND METHODS
The URIKA Bladder Monitor consists of an electronic case for generation and reception of ultrasound pulses. The case is
connected to the transducer assembly, containing a single-element 3.81 MHz transducer. The transducer assembly is
fixed to the lower abdomen by a belt with coupling gel. This pilot study includes 15 children (age 6-12 years) with DV.
The patient is subjected to an URIKA monitoring session of 1.5-2 hours, during which 2D ultrasound images are made
repeatedly as reference.
RESULTS
The study is on-going, but the first results show that the URIKA Bladder Monitor is able to detect the anterior and
posterior wall of the bladder. The calculated distance between both bladder walls is comparable to the measured
distance with 2D ultrasound.
CONCLUSIONS
Currently, the URIKA Bladder Monitor is able to detect the anterior and posterior wall of the bladder. In the future, the
alarm functionality will be investigated.
