This looks pretty interesting and can maybe provide an alternative to bladder management, rather than self catheterizing all day . At the moment the studies have been carried out on rats and looks to be successful.
There is still a long way to go before such a device can be used in humans. For instance, it needs to be miniaturized and made from materials that will work in the human body. However, the researchers foresee a handheld version that buzzes when the patient needs to use the bathroom, and when they are ready, they just press a button to start emptying their bladder.
I've always thought about something like this, definitely that'd make a difference in many lives! I can see this being something common in the future! freewheeler, I think it'd decrease UTI's as well having the ability to properly empty the bladder!
