Overview
Feasibility assessment of intravesical gentamicin instillation (putting antibiotics directly into the bladder) versus the current standard of care of oral nitrofurantoin prophylaxis (taking a low dose of antibiotics by mouth every day) to prevent recurrent urinary tract infections (UTI)
Description
The overall goal of this project is to assess the feasibility of a larger trial investigating the use of intravesical gentamicin instillation (putting antibiotics directly into the bladder) versus the current standard of care of oral nitrofurantoin prophylaxis (taking a low dose of antibiotics by mouth every day). Investigators plan to gain patient perspective regarding preferences for study design and assess associations between the treatments with changes in the postmenopausal urinary microbiome (urobiome).

Exclusion criteria:

- renal failure
- liver failure
- bladder pain syndrome
- multiple negative urine cultures associated with UTI symptoms (>/= 3)
- bladder Botox treatments in the past
- treatment planned for UI and prolapse
- unevaluated microscopic hematuria
- history of kidney stones
- no antibiotics within 4 weeks
- most recent weight <40kg (88.18lbs)
