Welcome to icliniq.com.
Your baby has proven UTI - urinary tract infection with Klebsiella and is Colistin sensitive and unfortunately not responding. Also, she had bilateral reflux, which is prone to cause recurrent UTI.
The reason for persistent urine infection may be underlying anatomical defects (the reflux), resistance to Colistin or involvement of upper urinary tract (kidneys).
I recommend you to repeat urine cultures and get an ultrasound examination to look for any complications developed and whether any intervention is needed now, as during active infection other imaging studies are deferred.
I need to know, how many episodes of UTI she had earlier? Also, give me more details of reflux and surgery done and antibiotic prophylaxis being used.
Please continue her antibiotics. Thank you.
