Essentially it is disrespectful to do something like that in a cemetery, and therefore not allowed, however in your situation, he seemed to be left with no choice. Additionally, the halachos of respect in a cemetery apply to the whole area of the cemetery, there is an opinion (Chazon Ish- 209-15) that it only applies to that part that has graves. Therefore, in this desperate situation, that he wasn’t relieving himself in the area of the graves, and it is only urinating, we can’t say that he did wrong.
