my baby had mild fever when he was 34 days old and fever was due to urinary tract infection and was given antibiotic. The ultra sound taekn on 7-1-2014 shows borderline peliectasis measuring 0.8 cm and is still under medication -cephalexin and doctor advised scan of kidney during first week of may. My question is whether this will affect kidney and whether he will be cured by this medeication. His right kidney is normal. He is having normal urine .
