Has the vet ever done a culture and sensitivity? If not, that should be
done, pronto. What other urinalysis has been done - pH, specific gravity,
etc.? What are Hannah's symptoms (urge? anything else?).

Drinking a lot/peeing a lot (PU/PD) is a symptom of a lot of things, as is
weight gain - Diabetes Mellitus, Diabetes Insipidus, Cushing's Disease, etc.
I would talk to the vet about urinalysis of a fresh catch (first thing in
the morning) and fasting blood work. IF you haven't done geriatric
bloodwork on Hannah before, now might be a good time to get started.
