Answer

Keeping the patient well hydrated is important, especially if an obstruction was recently relieved.

Drinking cranberry juice offers little benefit. Although it appears to inhibit E coli from adhering to human uroepithelium, the amounts of bacteriostatic hippuric acid that are present are unlikely to be clinically effective.

For complicated UTIs associated with struvite calculi, foods and vitamin supplements rich in phosphorus and magnesium are advised. Remember that divalent cations (eg, magnesium) can chelate oral fluoroquinolones, preventing their absorption from the gut.
