My father was admitted to the hospital on 15th August, he was suffering with e.coli urinary tract infection previously which after medication he hardly made any recovery. After being admitted to hospital the reports said his creatinine level was 4 and after two days it increased to 6.80 so temporary dialysis has been done as the bladder was blocked with all the waste and the urine was not able to pass through. After dialysis, (which was on 20- 21st Aug) the creatinine was reduced to 4. Something and is still under medication for the infection. Today the report indicates that his creatinine has increased back to 6.20. What can be the reason for this? And what would you suggest? Thank you.
