title: Lessons learned from a patient. Changing concepts rather than facts.
abstract: Many concepts pertaining to urinary tract infections and considered to be established or dogma are, in fact, incorrect or subject to modification. The physician should not be too rigid in his thinking regarding this disorder, as new knowledge constantly becomes available, disproving previously cherished beliefs. The case described appears to underscore this better than any hypothetical situation.
