Renal ultrasound for a urinary tract infection - should you wait until the infection has cleared?

I see not reason: We diagnose UTI with urinalysis and culture. The ultrasound is used to see if there is a reason for repeat infections e.g. Stones, tumors, blockages of flow for some reason. So doing it should be sooner than later. But you should wait until the infection proves recurrent i.E returns after treatment in females. In male patients, ultrasound is done earlier d/t infection is unusual in men.

No need: Can be performed during an active uti. Will need to be repeated if ultrasound demonstrates kidney abnormalities.
