Yes, as far as can be deduced from current research as well as the experiences reported by users here, there is reason to think that bladder toxicity applies to the entire arylcyclohexylamine class, which includes pretty much all known dissociatives except for DXM and the diarylethylamines (or "phenidines", ie, ephenidine, diphenidine, methoxyphenidine, isophenidine and any other rarer or yet-to-be-synthed ones that I forget).
So, PCP, ~PCE, ~PCM, ~PCPy, whatever else, "~PCx" compounds, yes, these should all be presumed to be bladder-toxic (and possibly slightly nephrotoxic as well) until anyone has solid evidence otherwise, which could be a while.
Ketamine and PCP are analogues of each other, fyi. Ketamine is something like 2-Cl-OxO-PCM... someone who knows more about chemistry please correct me there as I just deduced it from knowing that DCK (deschloroketamine) is 2-OxO-PCM, so just jammed the Chlorine back in...
