Intravesical Agents for Prevention of Recurrent Urinary Tract Infections.

Recurrent urinary tract infections (rUTIs) are common and can significantly impact a patient's quality of life. The mainstay of treatment is antibiotic-based, which contributes to the global problem of antibiotic resistance among urinary pathogens, so many alternative therapies have been explored. In this mini-review we evaluate evidence for intravesical agents that prevent rUTI, including antibiotic and nonantibiotic options. The current evidence supports the use of intravesical agents that replenish the glycosaminoglycan layer and of aminoglycoside antibiotics as safe and effective therapies to prevent rUTI. PATIENT SUMMARY: We reviewed evidence on the use of bladder instillations to treat repeated urinary infections. Studies have shown that agents that improve the bladder surface and one specific antibiotic class are effective and safe treatments for prevention of recurrent infections.
