My 94-year-old father-in-law (who lives with us) can get to the toilet with his walker, but he often urinates on his lowered pants rather than in the toilet. (My husband, his son, says he cannot find, or see, his penis.) This situation results in the need for more frequent showers, and the urine smell is very difficult to get out of his clothes. He is not incontinent, so Depends are not the answer. Any suggestions?
