Who knows, it might partially heal and give out on him or something during his next fight.
That would be super dramatic. I can completely picture it now O.o
Also, if Urahara was the one to make the Hueco Mundo gates they might have a problem. Seeing as karakura town has been moved and everyone in it was put to sleep. I assume Urahara and Co. are probably ready, or too powerful to be put to sleep or whatever. But now, even if Urahara made a gate for them, they would only end up where nothings going on.
