Depending on how often your husband empties/changes his pouch and how much hair he has on his tummy can cause the leakage. Finding a good ostomy/urostomy nurse and spending time on your computer finding out everything you can about applying the pouch may help. I have an ostomy so I'm only guessing about your husband's needs. Body hair could be a problem, which may have to be another place to shave when changing his pouch. Good luck,
