### output:

Hi, I can understand your concerns. Norfloxacin acts in kidneys, bladder and prostate. However, the beneficial effect depends on whether that particular bacteria are sensitive (i.e. gets killed by the antibiotic) to norfloxacin. Since you have been having recurrent infections it is always better to start antibiotic according to urine culture and sensitivity. Since you are having improvement in your symptoms, norfloxacin is acting well. Lactobacillus acidophilus and bilious are good bacteria that will help in preventing recurrent UTI. They are safe to take with norfloxacin. Did you undergo an uroflowmetry (test to detect and obstruction in urine flow)? You may need to be evaluated and treated for any obstruction in urine flow due to prostate enlargement, since this can cause recurrent UTI. Take a lot of fluids, pass urine at least once every 2 hours and take cranberry extract capsules twice a day. Small cysts in kidney are not a cause for concern. If you have diabetes or hypertension, these need to be controlled properly to protect your kidneys. I am available for any more clarifications you need, Wish you good health,
