UT question: Urinary tract infection

Just a question for those of you who may know.

I believe very strongly in UT. It helped me combat and beat and very serious illness.

But I was just thinking: If Urine can be such a healer and carries with it all the antibodies to treat the body's ailments...how can people get Urinary or bladder infections?

Shouldn't the urine itself heal it?

Looking forward to your thoughts,
