<s>[INST] Hi sir, my mom had a Kidney transplant an year ago. now a few days ago she got an infection ( E.coli ) due to which she suffered from fever . infection was sensitive to cefixime so zinacef 1.5G every 8 hours was injected for three days (still continued). now the fever n other physical conditions are fine except 80 puss cells in urine and pain in right old Kidney. Can it b that th right e puss is coming from the old failed kidney? [/INST] Hi. If there are pus cells in the urine the test to confirm infection would be urine culture and sensitivity. It is possible that the infection is in the old kidney. A review of previous records and an ultrasound or CT scan may help. Good luck. </s>
