Abstract
INTRODUCTION: Urinary incontinence is one of the most commonly treated disorders in children at school age. Recently, a new, wearable bladder sensor became available, the SENS-U Bladder Sensor. The SENS-U is a small, wireless ultrasonic sensor, which continuously monitors the bladder filling and provides a personalized notification when it is time to go to the toilet. In this study, the aim was to examine the performance of the SENS-U as a full-bladder-based notification system in children during daily life activities. PATIENTS AND METHODS: In this pilot study, children (6-16 years) who were admitted for an inpatient bladder training were included. Parallel to one training day, the child would wear the SENS-U to estimate the bladder filling and it informed the child when the bladder was almost full. When the child received a full-bladder notification, the child was taught to inform the urotherapist/researcher, in order to determine the level of response. RESULTS: Fifteen patients (boys/girls: 7/8; mean age: 11.5 ± 1.7 years) were included. Based on a personalized volume-based threshold, the SENS-U notified these children of a full bladder with a median notification rate of 92.9%. In the remaining cases, children voided before the threshold was reached (e.g. defecation). Children responded positively to the notification of the SENS-U, resulting in a median level of response equal to 100%. CONCLUSION: The SENS-U was able to monitor the natural bladder filling accurately during activities of daily living and provided a personalized notification to the children when it was almost time to go to the toilet. Future research will focus on investigating the efficacy of the SENS-U compared to daily clinical practices.
