Antibiotic Bladder Instillations vs. Oral Suppression for the Treatment of Recurrent Urinary Tract Infections

This is a research study that aims to determine if antibiotic bladder instillations (placing an antibiotic directly into the bladder) over several sessions at the office is a good option to prevent recurrent urinary tract infections, in comparison with oral suppression therapy (taking daily antibiotics in the form of pills by mouth). Oral antibiotic suppression therapy is currently the most common treatment route for recurrent urinary tract infections in post-menopausal women. The bladder antibiotic instillation may overcome the disadvantages of oral suppression therapy such as antibiotic resistance, certain side effects, and recurrence of infections after finishing the treatment course.
