My husband, who has moderate to severe dementia, is urinating less frequently than usual while his water intake is normal. I fear he is retaining urine. The hospice RN said the doc could do a rectal exam to check if his prostate is enlarged but that would be a nuclear war. My husband does not even like me to change his diapers anymore, so there is no way he’d let a stranger to probe his rectum. Is there another way to check his prostate?
