I think that's preference thing. This is all fantasy writing so I tend not to try to go for real death details. With that being said I have done a scene where the victim has lost bladder control before but that is about the extent of it. I would dabble in it in general but its really not in my wheel house. I usually keep it clean, yes I know its not as real but I'm not into real death and do this as fantasy and fiction so I think it works for my writing.
