I passed a kidney stone 10 days ago (at home, did not go to the hospital, have passed them before so I recognize the symptoms). Now with urgency, frequency and on a home test strip some leukocytes in urine (I do not see gross hematuria). Also, I am a sonographer - scanned myself - unable to tell if there are more stones and I do not feel like ultrasound is the best option to see small stones. Would an antibiotic help my symptoms?
