Recurrent uncomplicated UTIs can be frustrating to treat, especially when all other standard treatment options have been exhausted.

Patient profile:
• 25-year-old healthy female.
• No past medical history; not pregnant; no known allergies.
Current status:
• Presents to urgent care with dysuria, urgency, and suprapubic pressure x3 days.
• Afebrile, mild suprapubic tenderness, no CVA tenderness.
• Urinalysis: positive nitrites, leukocyte esterase.
• Urine culture pending.
History:
• Reports a similar episode 4 months ago treated with nitrofurantoin, but symptoms persisted, and she required a second course of TMP-SMX.
• Patient is now requesting “something stronger that will work the first time.”
1. How are you approaching empiric treatment for recurrent uncomplicated UTIs in young, otherwise healthy patients, especially when there’s a recent history of clinical failure with nitrofurantoin and TMP-SMX?
Are there newer oral agents you’re reaching for more often, given resistance trends?
Key takeaways for treating recurrent uncomplicated UTIs:
Family Practice
"In otherwise healthy young patients with recurrent uncomplicated UTIs and recent treatment failure with first-line agents, empiric therapy should be guided by local resistance data and prior culture results when available. In the absence of culture guidance, a different class from prior failures is preferred, such as a beta-lactam or, when appropriate, a short course fluoroquinolone (though the latter is generally reserved due to safety concerns and resistance risks).
Newer oral options, like fosfomycin, may be considered in select cases, particularly if prior infections involved multidrug-resistant organisms, though access and susceptibility vary regionally. Preventive strategies like hydration, post-coital voiding, and targeted behavioral measures remain important alongside acute management to reduce recurrence risk."
Internal Medicine
"Nitrofurantoin is still my first choice. Unfortunately, D-Mannose was proven ineffective in a recent study, but patients still reach for it for prevention."
Urology
"I would like to know if a culture was done with the first infection and if the new culture is the same bacteria. I would also like to know if these followed intercourse. I may consider prophylactic therapy with intercourse. She may need imaging if it’s the same pathogen.
I generally use full time prophylaxis for documented recurrent infections without a cause found and resistant to traditional treatments."
Internal Medicine
"For a healthy young woman with recurrent UTIs who didn’t respond to nitrofurantoin or TMP-SMX, I usually avoid those again and go with fosfomycin as a first choice while waiting on culture results. If needed, I might use cefpodoxime or Augmentin, depending on local resistance. I avoid fluoroquinolones unless there are no better options. I also ask about risk factors like sex, hygiene, and voiding habits, and if the UTIs are frequent, I consider self-start treatment or post-coital antibiotics."
Urology
"Personally, I would never start empiric treatment of a UTI with nitrofurantoin as it is bacteriostatic and not bactericidal. Macrobid/nitrofurantoin can be used for prevention of uncomplicated UTIs, but not necessarily treatment. Bactrim is my go-to for treatment, and if a sulfa allergy exists, trimethoprim could suffice.
I would also work up the patient to determine why there was a recurrent UTI with a good history/physical. Do these happen post coital, or is there an anatomic abnormality causing them? It should be the treating clinician's responsibility to explore this."
