Infections tend to arise when the body is in an imbalanced state. It could be an overabundance of stress, a poor diet, change in routine, major life event, etc. that caused the imbalance.
However, urinary infections generally respond well to elimination of sugars, grains, and dairy from your diet and drinking 1-2 oz unsweetened organic cranberry juice multiple times per day (unless you are diabetic) and drinking a lot of water (until urine turns pale yellow). Also eating plenty of dark leafy greens for their alkaline nature would help.
These tips are NOT a substitute for medical treatment.
This natural approach is NOT meant to kill the infection but rather boost your immune system allowing your body to better deal with the infection.
There's is NO natural substitute for antibiotics.
The medical approach is to kill the infection. The natural approach enhances your body's innate ability to do so. There's a time and place for antibiotics and other medicines.
If your M.D. prescribed antibiotics you should talk to them first about taking the antibiotics or holding off and trying a natural approach first.
