My husband has used a condom catheter and leg bag when going out to dinner and such for many years. But he finds he gets some irritation if he leaves it on more than 12 hours or so. Something like this: http://www.allegromedical.com/catheters-c539/ultraflex-p191771.html There are lots of different styles of condoms.
His last stay at the hospital, they tried to put one on Sonny. He fought them so badly they gave up.The NH does not use them.I was surprised that the hospital had no kind of adult diapers for the incontinent patients.
