My 12 year old daughter had an appendectomy a month ago. 10 days later she had a procedure to drain an absess from infection due to the appendectomy.  She completed PICC line antibiotics a week ago, but has had urinary issues for a couple weeks.  Today urine test came back that she has strep in her urine (UTI).  Is this related to the appendix/absess issues?  Why didnt the IV antibiotics kill any bacteria present?
HI appendix with mild ascites.... can cause ureter to get infected.....and secondly strep and staph are skin germs and rarely the ureter can be injured during operation....... they can be due to scar mark access if fistula is formed or simply SHE GOT DIFFERENT STRAIN OF STREP FROM THE ANTIBIOTIC U GAVE.EVERY ANTIBIOTIC HAS DIFFERENT SPECTRUM OF ACTIVITY.... JUST BY NORMAL ASCENDING URINARY TRACT INFECTION ...............TAKE CARE
