Just to provide an update, my experiments with condom caths have slowed to a crawl for unexpected reasons. My urologist had me intermittent cathing twice a day and taking a double dose of Flomax. As my post-void residuals had dropped, I expected my urologist to discontinue one or both of my intermittent catheterizations.
To my surprise, at my last appointment with my urologist he wanted me to increase intermittent cathing to 4 times a day!

I guess the drop in my residuals was good - but not good enough, considering that I was taking double Flomax.
I negotiated down to only 3 intermittent coatings a day due to complications with my fecal incontinence and the difficulty of cathing after I have on barrier cream, diaper, PUL pants, and compression pants.
The bottom line is that it now has become much more difficult to use the condom caths! I have decreased the number I receive per month from my medical supply house. I will continue to experiment on a reduced basis. I will use the condom caths during my cruise in January as my urologist said that I could drop back to only one intermittent cath per day for that period.
Again, my thanks to all who have assisted and guided me with the condom catheters.
