Repeat culture.: Sounds like you have already seen urologist and that you have a recurrent rather than relapsing uti. If i were your physician i would obtain culture before treating. In absence of any other contraindication i would use Nitrofurantoin 100 mg PO bid.

Once this current infection is under control, talk to your doctor about using Methenamine Mandelate to prevent future UTI's.
