In brief: Possibly
Cranberry juice has a substance called tannins which make it harder for bacteria to attach to the bladder and cause infections.
Cranberry can help some people reduce the risk of recurrent urinary tract infections. Drinking cranberry juice shouldn't hurt and may help. If your symptoms are not improving, should be evaluated by your physician.

In brief: To Prevent UTI ONLY
There is data to support the use of cranberry juice or extract to prevent recurrent, culture proven utis.
However, review of studies intending to treat a UTI with cranberry failed to show any benefit. Thus, cranberry juice/extract will only help to prevent utis. Unfortunately, maintaining adequate intake over the long term is difficult, and studies suggest it increases kidney stone production.

One of the sugars in cranberry juice is L-mannose which can be purchased and taken at first sign of UTI. Bacteria eat this in bladder and slide off wall to be washed out.

We hear this a lot but not sure how good it is and i don't think that there is good data to support.
