That's one of the reasons with my urge UIC that I prefer wearing diapers. Whenever and urge comes up, I can freely decide - no matter what I'm doing, where I am, what's the surrounding, if a bathroom is nearby or not - if I want to try to hold in and find out if it starts hurting or not, or if I rather release - either only a spurt, or in worse case, the full bladder. Even if short time later the next urge comes,I can simply push out everything. It's quite important for me as well to empty out everything from time to time as also to try sometimes to fill up the bladder completely, no matter if I'm on a toilet or not...
