TENA SmartCare Bladder Sensor · Ages 6+
Confidence that grows day by day
5.0 · Parent reviews
The sensor measures the bladder with ultrasound and sends a discreet notification when it's full, so a leak can be prevented before it happens.
Studied and used in multiple Dutch hospitals
Non-invasive: ultrasound, no radiation
Discreet notification: only your child notices
Working with the bladder sensor is experienced as very pleasant within the Paediatric Incontinence Team. It is user-friendly, and the results show an improvement in symptoms in more than 80% of patients.
Nurse Specialist in Paediatrics, Jeroen Bosch HospitalThe science behind it
It's not magic, it's science
Picture the bladder as a balloon. As urine slowly enters, the balloon gets bigger and bigger. The trouble is that children do not always feel it filling, or only notice the signal once it is too late.
The patented sensor makes that filling visible. It sends harmless sound waves to the bladder and measures the echo that returns, much like an echo off a wall. No radiation, nothing invasive. At 80% full your child gets a discreet notification, before anything goes wrong, and over time they learn to recognise their own bladder signals.
The same technology as a pregnancy scan · Class IIa medical device.
Three moments every parent recognises
01
The sleepover
They say no. Better not than risk it.
02
Three in the morning
The washing machine again. Another short night.
03
The guesswork
Do they need to go now, or later? You simply don't know.
Sound familiar?
Then you don't have to guess any more
The sensor shows bladder filling and flags the moment to go to the toilet, before it goes wrong.
Not a warning afterwards, but a signal in time.

What changed at home
The sensor brought relief by showing there is a real medical issue, not laziness or misbehaviour. That recognition alone changed everything for him.
The experience has been very positive. He's really starting to feel when he needs to go, and that helps him a lot in learning to recognise the urge.
The sensor is small and comfortable. It fits in a discreet black pouch so her friends don't accidentally see it.
