He may not like the type of product as many people find a 'diaper-like' product irritating. I sugegst your mother find something else to contain the urine leakage. You may want to look at TENA products as they have a pad and pant system that is good at containing urine and is less irritating. Another option is for your Dad to use an external condom catheter at night. Also what about a urinal next to the bed?
