@lisalucier Actually I am not 100% sure that I have had a UTI. When I first had episodes of confusion (HE), one of the possible causes mentioned was UTIs and I tested very low but was put on an antibiotic regardless. Of course now we know that UTIs were not the cause, and also I have learned that a very low number generally does not mean you have a UTI. The old thinking was that urine was sterile. That is no longer considered to be true.
Now, due to my immunosuppressants, I tend to be very careful about hot tubs. I don't want to tempt fate. I have used the one at my health club a few times when I have been in the pool for an hour or so and noticed that no one had been in the hot tub during that time. I assume that in an hour any germs in there would be killed by the chlorine. My transplant surgeon, when I told him that and asked him if it was OK, said he would leave it up to my discretion.
