The uro's office just called a just told me that I had a positive urine
culture. The physician's assistant told me something that I have not thought
of before.  He said that the sphincter works both to keep the urine in and
to keep bad things out.  When a person is incontinent, i.e., malfunctioning
sphincter, then it is more likely that pathogens can find their way into the
urinary tract and bladder where they do not belong.
   So, the point here is that trying to keep down the number of pads per
day can be counterproductive.  Changing more frequently, I would think,
reduces the risk of exposure to harmful organisms that may grow in the warm
moist environment of the soiled pad.
   Just a thought.
