COPD inhalors and BPH problems

[tethered goat]

I was recently diagnosed with Emphysema,  as i have never smoked or had a "dirty" job this was a real <deleted> moment, i knew little or nothing about it. I was given an inhalor and sent on my way.Nobody asked me if i had BPH [enlarged prostate] Within 3 weeks i was in hospital with severe urinary tract infection , infection of the prostate and an inability to pee.The uroligist said it was caused by the inhalor shutting down my urinary tract.

I started looking at the research on this and discovered that 15 to 20 years ago it was established that there was a direct causal link between COPD inhalors and urinary retention in elderly men with BPH who were using an inhalor for the first time.  I ticked all the boxes yet 20 years after this being established nobody thought to ask.I can find no recent research on this and no information on more modern inhalors, if there are any that are less likely to cause this problem.

My current treatment for Emphysema is one pill a day [doxophylline 400mg]  I have nothing to compare it too regarding relief using inhalors,but i'm not feeling that good.I recently had a situation where someone using an inhalor would use their ' rescue inhalor ', i had no such choice i just had to suffer my way through it

It is the lack of interest from most Lung specialists i find most frustrating , 99% of treatment development for moderate COPD is inhalors and then there is one pill. Does anyone know a Lung specialist in Bangkok who acknowledges this as a problem and may have more info.
