I spend a lot of time on conference calls at work, and I have a wireless headset which has been a life safer for me (I don't have UC, but I've been trying to drink more water, and I seem to have to go to the bathroom every 15-20 minutes). So, I put myself on mute, go to the bathroom, and when I'm out take myself off mute.
At work for me, it is a shared restroom with multiple stalls, so if someone is in there with me, if I take myself off mute, even if I don't flush, if the other person does . . . So, it's not perfect, but it's far better than trying to hold it.
At home, I used my cordless phone (the handset also has a speaker phone), and I put it on speaker, and put myself on mute. I hope this helps you. Also, if your urgency is really bad, your flare is probably not under control - so you should (if you aren't already) look into what you can do to quickly bring this flare under control. Also, in the past, I've heard quincy mention a med (I think the name is Bentyl) for urgency - maybe someone can update this ticket with the meds that help with controlling the urgency associated with a UC flare.
Feel better soon.
