Urinary retention is a side effect of a class of drugs. Actually, several classes.

"Urinary retention has been described with the use of drugs with anticholinergic activity (e.g. antipsychotic drugs, antidepressant agents and anticholinergic respiratory agents), opioids and anaesthetics, alpha-adrenoceptor agonists, benzodiazepines, NSAIDs, detrusor relaxants and calcium channel antagonists."

Whether an individual drug in a class gives you this side effect can only be determined by trial and error. Just because drug A in that class gave you that side effect does not mean that drug B would, too, even if this side effect is included in the list of side effects. So I would still try it and see what happens.

It worries me that you say that you do not need an antypsychotic because you are currently not experiencing psychosis. I made the mistake of thinking this way in the past, much to my detriment which I will not describe here. Antipsychotics are now a first line of treatment for bipolar, regardless of whether you have psychosis currently. They prevent mania and depression and are very important in your case, imho. Just because their name is antipsychotics does not mean that there are purely for the treatment of psychosis. Their use is far broader than that.

Of course, it must be awful to be a catheter and I am sorry you have to go through this, and during holidays!
