PURPOSE

In children at school-age (6-10 years), the prevalence of daytime incontinence equals 6-9%.

Children often experience a reduced bladder sensation, which makes it difficult to recognize

a full bladder. For this reason, we have developed the URIKA Bladder Monitor (UBM): a wireless

ultrasound-based sensor which detects a full bladder before voiding and informs the user to prevent

urinary leakage. Previous results showed that the UBM was influenced by sensor movement and

a minor detection area, resulting in a detection-rate of 71%. In this study, the aim is to evaluate the

feasibility of the optimized UBM after increasing the detection area and improving sensor fixation.

MATERIAL AND METHODS

The optimized UBM uses multiple ultrasound transducers, which results in an increased field of

view (30 degrees). With a skin-friendly adhesive patch, the UBM transducer is positioned to the

lower abdomen combined with an elastic belt. In this feasibility study, 12 children (6-12 years)

with daytime incontinence are subjected to an UBM monitoring session during which a full bladder

is detected four times. Transabdominal ultrasound (TUS) was used repeatedly as reference. The

estimated bladder dimension are analyzed by descriptive statistics. The level of agreement between

these methods are analyzed by the Pearson’s correlation coefficient and the Bland-Altman plot.

RESULTS

The optimized UBM is able to measure the changes in bladder size over time repeatedly and ac-

curately. A pre-selected volume to go to the toilet for micturition can be installed in the system.

CONCLUSIONS

The optimizations of the UBM result in a higher detectability of a full bladder, giving a signal to the

child when the pre-selected volume to go emptying the bladder has been reached.
