Maybe he's captured and tormented into it by Fisk.
Maybe he's always wet the bed and wakes to find he's done it again - but Foggy or Karen or Claire are there this time, and they clean him up and take care of him.
Maybe he's out beating up bad guys, but has a full bladder, and when he's knocked to the ground at one point, it just gives out on him and he pees everywhere.
